You mention that you are not interested in Britain's overall military fortunes. And it appears from the research that Blair wasn't interested in it either. By examining the U-boat peril in "isolation", Blair has both handicapped his research and its results.

Let me explain.



Hi back at ya :)

Handicapped? how so? You say the Uboat was the biggest threat and most sucessful weapon, so I fail to understand all this other talk about the BoB or Germany's conquests on the continent. Britian won the BoB and by doing so was immune to that situation. It was therefore up to the uboats to starve a defiant nation into admitting defeat. To do so, we need to see conclusive proof that this "brink" was reached.


It does not take much logic to conclude from the above, that if 20 U-boats can bring Britain's naval resources to the breaking point, then adding 20, 30, 50 or more U-boats can effectively help tip that balance. Yet again, this type of analysis is ignored by Blair.

By leaving out all outside influences on the development of the U-boat, its use, and the interference in its operation, leaves Blair's book, while good in so many other ways, as myopic in approach.

The evidence is clear: the U-boat was a highly effective instrument of German warfare. The biggest problem in its failure to eventually defeat Britain was not in its use; rather, the problem was that more U-boats were not employed in attacking Britain's shipping.



Forgive me for being obtuse, but "what" evidence? Again your transposings are mostly subjective commentary from authors and current newspapers regarding the losses which i have no doubt at the time were alarming tio them. However once more you fail to give any data that shows that Britian's economy and her people's bellies were brought to the breaking point.

Your figures also skillfully blend two vital periods of time.....before and after America's entry. I thought we were now talking about the effect of the Uboats before 1942? Regardless in the end the numbers you keep repeating are but raw tonnage data. No-one is disputing this. What i asked is for you to show data that refutes Blair's contention that the sinkings did not come dangerously close to severing Britian's lifeline

According to his data which you say he is painting a faulty picture with, in the first 28 months of the war Britian sailed 900 Atlantic convoys, Britian's "lifeline" so to speak. Uboats achieved victories (defined as 6 or more ships sunk per convoy) over but 19 of them.

Total ships involved in these 900 convoys comprised 12,057 ships. Uboats sank 291 of them. That accounts to 98% of all ships in these convoys reaching the British Isles.

So you see, this isn't about the law of averages 1939 - 45 diluting the shipping losses.

Finally, Blair's thesis, to which i continually refer, is *not* that the Uboats were'nt a threat at all.....his thesis states that the uboats never came close to acheiving their strategic goals and in the end, you have yet to provide evidence to the contrary.

We can talk about the number of ships sunk and talk about % totals of the pre-war British merchant fleet sans replacements etc etc etc, complete with dramatic adjetives including staggering and terrible till the cows come home.... but all your "sources" give nothing but dramatic ancedotal info without any real statistics outside of occasional raw tonnage figures of ships sunk without any corresponding data that shows Britian was on the edge of economic ruin and starvation.

And btw, whats this about 20 uboats bringing Britian's naval resources to the breaking point?? I number the total # of boats at 153.

60 years after the fact we know the USA entered the war. But in the dark years of 1939, 1940, and 1941, the British had no such knowledge, nor the luxury of having those ships at that time.

Remember, 50% of all Allied shipping that was sunk in all of WWII fell on Britain in those first two years.

Germany could easily have built 20 U-boats per month from Sept/39 onwards. That Germany did not do so, is a product of Hitler's bungling, and not because the U-boat was not effective.

Cheers!


In the last seven months of 1941, U.S. tonnage supplied British campaigns
in the Middle East, Africa, the Persian Gulf, and the Indian Ocean with
48,958 vehicles, 302,698 tons of dry goods, and 814 airplanes.

They are in violation of neutrality but what are the Germans going to do about it? I'll be back later after I complile how much the USA shipped in own bottoms in 1939-1940 (To discover how soon Germans would be faced with allowing shipment or bringing in USA)

It was therefore up to the uboats to starve a defiant nation into admitting defeat. To do so, we need to see conclusive proof that this "brink" was reached.


Mentioning the BoB, North Africa, and the fact Britain was fighting all alone, shows that Britain was stretched to the limit. This is living proof of Churchill's statements - that Britain was at the breaking point.

That Britain was not defeated is a combined product of:

1) allowing 330,000 Allied soldiers to escape from Dunkirk

2) Hitler's decision to build capital ships; and few U-boats between 1937 - 1939.

3) The decison to build so few U-boats in the first year of 1939 and afterwards.

4) Hitler's interference in the operation of the U-boat campaign.

5) Hitler's decision to invade the USSR rather than North Africa, then knock Britain out of the war.

6) The decision to switch from bombing British airfields to bombing British cities instead.

Since Britain was fighting the war alone, and since it was stretched to the limit, then it follows that any pressure that is exerted in any of the areas I mentioned above, would help push Britain over the brink, especially if at least 20 U-boats had been built per month from Sept/39 onwards.

The British situation simply cannot be examined in isolation, especially as it relates to the U-boat.

Many on this board have stated that Britain was never close to defeat. I have shown that in fact they were close to defeat, IF the proper amount of pressure had been exerted.
Forgive me for being obtuse, but "what" evidence? Again your transposings are mostly subjective commentary from authors and current newspapers regarding the losses. . . According to his data which you say he is painting a faulty picture with, in the first 28 months of the war Britian sailed 900 Atlantic convoys, Britian's "lifeline" so to speak. Uboats achieved victories (defined as 6 or more ships sunk per convoy) over but 19 of them.


Subjective evidence? Please take another look at all the evidence and quotes I have provided in the past several posts. You have yet to provide a single reference.

I have used factual information from a variety of highly reliable sources. Your source is Blair, himself. You provide no reference for this information. Worse still, Blair provides no footnotes for this information, so it is almost impossible to check his figures.
Finally, Blair's thesis, to which i continually refer, is *not* that the Uboats were'nt a threat at all.....his thesis states that the uboats never came close to acheiving their strategic goals and in the end, you have yet to provide evidence to the contrary.


That is the problem with his research. He looks at the bare numbers and draws his conclusions without taking into account the REASON WHY THE U-BOAT FAILED. I have provided ample evidence and reasons for the U-boat failure in my previous posts. Have you just ignored them? Again, the discussion is going round and round. . .

It is very clear that Britain could have been defeated in the first two years of the war, especially after Dunkirk. Even Churchill admits it! The fact that Hitler did not capitalize on Britain's weaknesses, is something we can all be thankful for.

What would Britain have done if none of the 330,000 Allied soldiers had escaped from Dunkirk? They could have been captured. Britain would have been defenseless. . .

The failure of the U-boat was but a symptom of the larger bungling of the war by Hitler. The U-boat was an effective instrument of war if used properly and in larger numbers. Britain could have been defeated if Hitler had taken the proper steps.
And btw, whats this about 20 uboats bringing Britian's naval resources to the breaking point?? I number the total # of boats at 153.


I was merely giving a number as an example.

Some helpful facts

Post by mogami »

Hi, I'm learning a lot about U-boats and merchant ships.

UK started war with 21mT of merchant shipping. Needed yearly imports of 43mT after rationing. (Every ton of shipping sunk = 2T of goods/yr. lost.)

1939
U-boats sink 755,000 tons British replace (new builds) 320,000 tons.

Polish merchant fleet of 54 ships 188,000 tons escapes to Scotland (320+188=508k tons) (These ships carried over 5 million tons during war)


So in 1939 Germany was plus 247k tons 21,000,000-247,000

1940 to follow

1940

U-boats sink 4million tons

1.2 million tons new builds

Norway
233 Tankers fell under Allied control after the Apr 9 1940 invasion of Norway. These ships were to prove vital during war. Over 500 Norwegian ships would be lost during battle of Atlantic. (over 1000 ships went "Allied") using 2.5k I'll add 2,500,000 tons for these and 582,500 for the Tankers (and I know this is way below real tonnage)

Denmark
800,000 tons went to Allies after Denmark was over run.

4,000,000-5,082,000 Germany is behind 1,082,000 for 1940 and 835,000 tons overall. (British begin Sept 39 with 21MT begin 1941 with 21,835,000 ton)

1941 to follow

I dont need too. I have Blair......which 'you' say draws faulty conclusions from the 'data', but none of your quotes or sources refutes his data. All i've seen is raw tonnage data which we already know and quotes from sources at the time waving their arms in the air for dramatic effect talking about how scary the big bad uboots were. Thats fine but NOT what i asked you for. I only use Blair because his is the only source that makes this contention and provides statistical data.

ok, so in the absence of counter data we now have to attack Blair's. Fine.

That is the problem with his research. He looks at the bare numbers and draws his conclusions without taking into account the REASON WHY THE U-BOAT FAILED. I have provided ample evidence and reasons for the U-boat failure in my previous posts. Have you just ignored them? Again, the discussion is going round and round. . .

At this point, yes i am ignoring parts because as this thread has ground down to a halt i've gotten more specific in my questioning and focus while you continue to dance about until we're now talking about the entire war effort between Germany and Britian before 1942. I did listen to your objections regarding Blair, i even conceeded several points regarding critisim on his work and focus, particularily in regards to his treatment of the USN. However 'you' have failed to provide me with one source that refutes Blair's #'s in regards to the success of the vast majority of loaded cargo ships reaching Britian, nor data that shows that Britian's economy and people were brought to the brink of economic ruin and starvation by said Uboats. Thats all i care about at this point. If you want to talk about Uboats in conjunction with other strategies and war efforts....thats a whole different ball park.

I was merely giving a number as an example. [/B]


Well it was a poor example, .....which tied along with the continued use of the words 'staggering' and 'tragic' would seem to present as skewed an argument as you accuse Blair of doing only this one in favor of the "legend" of the Uboat. I am truely interested in what other authors have had to say, good and bad about Blair's "definitive" work. Thats why i'm pressing so hard to see the hard data none of them have shown as of yet. If Blair's revisionism is indeed false, then it shouldn't be that hard to produce......unless of course he's right in his thesis and the Uboats never came close to severing the lifeline in spite of the signifigant damage they did.

Hi, I was very amazed to find Britian had almost a million more tons of shipping going into 1941 then she had in Sept 1939.
Now of course 300 U-boats would alter this but it's interesting to me to note that in the actual event the U-boat were clearly losing the tonnage war going into 1941.

(and dispite Drumroll I discovered that the USA "assumed control" of over 500,000 tons of ships from other countries in July 1941)

1941

U-boats sink 4,330,000 tons

New Builds 1,800,000 tons

Germans plus 2,530,000 tons for 1941 and 1,695,000 tons over all. (Not counting the 84 ships over 500,000 tons the USA added from ships in port aquired in July)(or the US merchant marine in Dec since it had been active the whole war, the numbers just make the U-boat effort appear hopeless)

1942 to follow.

1942

U-boats sink 6,700,000 tons
New Builds 7,000,000 tons

Germans minus 300,000 tons for 1942 plus 1,395,000 over all

(I'm using the lowest numbers for Allied builds. I have many that would have Germans minus 3MT by end of 1942

1943

U-boats sink 2,300,000 tons
New builds (lowest figure I find) 14,400,000 tons

Game set and match to allies......

No where, do I see the U-boat coming close to defeating Britian.

To quote Blair:

". . . the U-boat peril in World War II was and has been vastly overblown."

My evidence was to show that it was not over blown.

Also, many on this board said that Britain was not in danger of being defeated. My "extra" evidence showed otherwise.
I dont need too. I have Blair......which 'you' say draws faulty conclusions from the 'data', but none of your quotes or sources refutes his data.

Ah, yes you have Blair. Where would we be without Blair. You hang onto his book as though it is the Holy Grail. LOL

His book is full of faults, no less being it contains no footnotes so we cannot check his data. Further, his pro-American bias is everywhere in the book. The British and Germans are roundly criticized, but he has almost 300 pages to devote to defending King's abysmal lax attitude regarding east coast convoy protection.

It is difficult ultimately to accept Blair's claim that the loss of 596 merchant ships of 3.5 million tons to enemy action between September 1942 and March 1943 was not a crisis simply because most ships in convoy arrived safely and Allied shipbuilding replaced those lost.

In order to win the tonnage war, the Allies had to divert an extraordinary amount of resources away from the production of tanks, landing craft, aircraft and other armaments necessary for the invasion of Europe toward the production of merchant ships and escorts.

Indeed, the argument that the tonnage war was a misguided strategy from the outset pre-supposes both the entry of the United States into the war and the presence of a viable alternative to it for Germany.

"Arms waving in the air?" Please.

Winston Churchill, as the leader of Great Britain, was briefed daily on all activities on air, land and sea. He had a very clear idea of what was happening. The information was so bad, he eventually stopped giving loss figures to Parliament, because they were so depressing.

Out of the HUNDREDS of historians who have written about the Battle of the Atlantic, ONLY Blair makes the contention that the U-boat war was not that serious. LOL

I guess all these other historians are flighty individuals running around waving their hands in the air whenever the word "U-boat" is mentioned.

To paraphrase Tweedy Bird: "I did, I did. I did taw a U-boat."
'you' have failed to provide me with one source that refutes Blair's #'s in regards to the success of the vast majority of loaded cargo ships reaching Britian, nor data that shows that Britian's economy and people were brought to the brink of economic ruin and starvation by said Uboats. Thats all i care about at this point. If you want to talk about Uboats in conjunction with other strategies and war efforts....thats a whole different ball park.


No one said the British were starving, even though rationing was instituted, and everyone had to grow gardens. Even so, just three weeks interruption of the convoy system would have resulted in dire shortages.

The British Prime Minister, Winston Churchill, in a broadcast on 27th April 1941, made clear that the most important theatre of the war for Britain lay in the Atlantic:

"Still, when you think how easy it is to sink ships at sea and how hard it is to build and protect them, when you remember we never have less than 2,000 ships afloat and 300 to 400 in the danger areas, when you think of the great armies we maintain...and the world-wide traffic we have to carry, can you wonder that it is the Battle of the Atlantic which holds the first place in the thoughts of those upon whom rests the responsibility for procuring the victory?"

And while convoying did undoubtedly reduce sinkings and save lives, the introduction of the convoy system led to a temporary but critical one-third reduction in the quantity of imports reaching Britain, a fact which caused Churchill much concern.

In addition to a one-third reduction in imports, there was also the 2,500 ships that had been sunk in the first two years of the war.

War is waged by much more than having a few carrots and potatoes to eat. It requires prodigious amounts of oil, metals, parts, tanks, aircraft, ships, factories, money etc, etc.

And every ship sunk, places the recipient in a far worse situation.

In early 1941, not only was Britain running out of gold and cash (in fact it couldn't even pay the US for any of the armaments it was building), but the ships the USA was building would only meet half of Britain's shipping requirements due to losses sustained (page 692, Gilbert's "Churchill").

Well it was a poor example, .....which tied along with the continued use of the words 'staggering' and 'tragic' would seem to present as skewed an argument as you accuse Blair of doing only this one in favor of the "legend" of the Uboat. I am truely interested in what other authors have had to say, good and bad about Blair's "definitive" work. Thats why i'm pressing so hard to see the hard data none of them have shown as of yet. If Blair's revisionism is indeed false, then it shouldn't be that hard to produce......unless of course he's right in his thesis and the Uboats never came close to severing the lifeline in spite of the signifigant damage they did.


It was a just a figure to illustrate my point. Relax.

Mogami:

Interesting. But what are your sources for all these figures?

Here are estimates:

Between Sept/39 to Dec/40, 1,280 British, Allied and Neutral ships were sunk, for a total of 4,700,000 tons.

Between Jan/41 to Dec/41 another 1,299 British, Allied and Neutral ships were sunk, for a total of 4,329,000 tons.

[This period between Sept/39 to Dec/41 represents 50% of all Allied shipping losses sustained in all of WWII. The main burden of these losses fell on Britain].

January 1942 to May 1943 another 2,029 British, Allied and neutral ships of 9,792,000 tons ( 576,000 tons per month)

June 1943 to May 1944 Total Losses = 324 British, Allied and neutral ships of 1,733,000 tons (144,000 tons per month)

Source:
http://www.naval-history.net/WW2CampaignsUboats.htm


*************

Also the following must be taken into consideration:

1) In the summer of 1941, Hitler ordered 12 U-boats to leave the Atlantic and to go to the Med. This hindered Donitz's campaign against Allied supply ships, effectively giving the Allies a two-month holiday, allowing convoys to get through, and unload supplies in Britain.

2) In 1942, Hitler again intervened and ordered more U-boats to be sent into Norwegian waters because he thought the British were going to attack it. Again, this allowed convoy ships to get through to Britain unmolested.

- (source: "Chronicles of WW II", pp 222-223)

3) The fact that so few U-boats were built initially.

4) During the first year after the war had started, the U-boat construction programme had almost been halted; only thirty-seven new boats were commissioned in those first twelve months, despite earlier plans to have over 100 boats in that time. Hitler had hoped for a quick vistory on the Continent and that Britain would agree terms for peace when she found that she stood alone in Europe. It was 1941 before the building programme was really going again, but a valuable chance had been lost. Although 230 new boats were being built in April of that year, only thirty-two boats were available for operations!

If Hitler had not miscalculated the British mood and had allowed the U-boat building programme to proceed in 1940, Donitz could possibly have won the Battle of the Atlantic in 1941 or 1942. . .

- (Source: "Convoy" by Martin Middlebrook, NY, 1977; pp ix, 8, 17, 18)

*************

That so few U-boats could inflict such great damage is testament to their effectiveness.

The fact that they were not more effective is due to Hitler's bungling and the low numbers used in the battle of the Atlantic.

Numbers

Post by mogami »

Hi, Our numbers match for period from Sept 39 to Jan 42.
After that it does not matter U-boats have lost. (They do have best period but alas for them the enemy total has more then doubled.
In 39 they are after 21mT in 1942 The Allies have at least 50MT (I'm guessing the USA had at least as large a merchant fleet as Britian)

Yes they do a lot of damage but they would need to almost triple the historic damage to be making real progress.

Germany had no hope of defeating the USA. It needed to defeat Britain (and it could defeat Britain if the proper resources had been placed in the battle).

Between Sept/39 to Dec/40, 1,280 British, Allied and Neutral ships were sunk, for a total of 4,700,000 tons.

Between Jan/41 to Dec/41 another 1,299 British, Allied and Neutral ships were sunk, for a total of 4,329,000 tons.

[This period between Sept/39 to Dec/41 represents 50% of all Allied shipping losses sustained in all of WWII. The main burden of these losses fell on Britain].

These are the real meaningful numbers. For such a small U-boat fleet they inflicted a great deal of damage. The real significance of all this lies in the fact that had Hitler committed to a large U-boat fleet early on, then Britain could have been blockaded into submission.

Frankly, Blair's underlying thesis that the U-boat threat was overblown, simply does not hold water, considering the damage they did do, as well as the terrifying potential they had (if produced in larger numbers).

That this did not happen can only be accounted one of the true lucky "circumstances" of the war.

Finally, raw numbers simply do not tell the whole tale. One ship sunk; two built.

This becomes even more evident when we consider what just three airliners and 19 men caused on 9/11.

U-boats

Post by mogami »

Hi, You keep forgetting the Germans keep giving the British more ships then they sink.

In Sept 1939 Britian has 21,000,000 tons of shipping.
They need 43,000,000 tons of goods per year.

In 1939 they sink 755,000 tons but the British get 500,000 tons back (new builds and the Poles.

In 1940 they sink 4,000,000 tons (this would have been a disaster except the British get 5,000,000 tons back (New,Norway,Denmark (and I'm sure I forgot to add a few ships from France Belguim and Holland)

So when 1941 begins the Germans actually have more ships still to sink then when they began in 1939. Thats the problem.

Mogami:

By your own reckoning, it takes the Allies 4 years (until 1943) before the Allies (mainly the USA) produce more ships than are being sunk. This, in and of itself, defeats Blair's thesis that the U-boat threat has been overblown. In addition, it took the entry into the war of the USA to overcome these ship losses.

You mention Britain getting all these other nations' ships. I do not doubt your information. I was just wondering what are your sources for this information? Just because France has 50 tankers, does not necessarily mean that they will wind up in British hands.

If I remember correctly, the British sank a large part of the French fleet. Not sure the French would be so obliging to hand over supply ships to them.

In early 1941, not only was Britain running out of gold and cash (in fact it couldn't even pay the US for any of the armaments it was building), but the ships the USA were building at that time were less than half of what Britain needed, due to losses sustained. This was according to Churchill, himself. (page 692, Gilbert's "Churchill").

Also, many on this board said that Britain was not in danger of being defeated. My "extra" evidence showed otherwise.
I guess i need reading glasses because i do not see this evidence. I see a bunch of opinions, negative reviews on Blair and dire predictions and forcasts. I need not repeat anymore what i've been asking you for.

Ah, yes you have Blair. Where would we be without Blair. You hang onto his book as though it is the Holy Grail. LOL

His book is full of faults, no less being it contains no footnotes so we cannot check his data. Further, his pro-American bias is everywhere in the book. The British and Germans are roundly criticized, but he has almost 300 pages to devote to defending King's abysmal lax attitude regarding east coast convoy protection.
Tsk tsk my friend. I do not consider Blair's book a holy grail. That is my whole point. I've listened, and listened and listened to your continued pointings towards what are perceived as his "faults" yet in the end you can provide no counter-data regarding the economic situation nor can your critics refute Blair's findings that most cargo ships made it to their destinations. I am only asking what any "Blair fan" would, who might use the source to run away and say that the uboats were nothing at all. I dont think the uboats were nothing, but i have yet to see any data that refutes Blair's thesis that the UBoats never came close to acheiving strategic success.

Yes, he criticises the British and Germans, yes he devotes pages to exonerate the Americans....yes he likes King. I've pointed out that he does the same thing to the American silent service in his earlier book and levels harsh critisim on his own Silent Service. So maybe he's just a hard taskmaster when it comes to sub ops. I know the raw tonnage figures, you've repeated them over and over. I am only interested in the state of Britian's lifeline and the uboat objectives. All you've been able to do here is talk about lack of footnotes (there are some in the book) and that his "data" cant be checked. Well that might be true given how many years he spent pouring over the documents and records in London and Washington. Last i checked, noone faults Blair for his research, only his writing methods from the thumbs down reviews you've transcribed.

It is difficult ultimately to accept Blair's claim that the loss of 596 merchant ships of 3.5 million tons to enemy action between September 1942 and March 1943 was not a crisis simply because most ships in convoy arrived safely and Allied shipbuilding replaced those lost.
Sigh. Well here we are back in 1942 after the USA entered the war. So you conceede then Britian's lifeline was hardly severed before American entry into the war? Define "Crisis", i could see a crisis in leadership when someone has to explain why so many American ships got sunk when perhaps the "tools" were available and that it might have been prevented, but this 'crisis' does not automatically evolve into a crippling blow to the Allies. 3.1 million tons of shipping is alot. 30million tons total shipping is alot more. Replacement of 85 - 90% of that lost shipping same year counts alot too.
In order to win the tonnage war, the Allies had to divert an extraordinary amount of resources away from the production of tanks, landing craft, aircraft and other armaments necessary for the invasion of Europe toward the production of merchant ships and escorts.
No argument here. Blair agrees. other sources agree. we all agree. However this is a moot point as well. The Allies had to divert resources, but they still won. Neither does this facet translate into a crippling blow. It was not Doneitz's goal. His goal was maritime defeat of the enemy and Blair's thesis is not about resource divertion, its about how close the Uboats came to acheiving strategic victory.

Indeed, the argument that the tonnage war was a misguided strategy from the outset pre-supposes both the entry of the United States into the war and the presence of a viable alternative to it for Germany.
Not if Blair's info on Britian is correct. I might not use the term 'misguided' myself as it does smack of hindsight, unless one considers Germany's technological challenges in facing this new uboot war, perhaps a better term is "doomed" for it would have required more changes than meerly producing a few more boats and the world economy was different from the last war.

"Arms waving in the air?" Please.

Winston Churchill, as the leader of Great Britain, was briefed daily on all activities on air, land and sea. He had a very clear idea of what was happening. The information was so bad, he eventually stopped giving loss figures to Parliament, because they were so depressing.

Out of the HUNDREDS of historians who have written about the Battle of the Atlantic, ONLY Blair makes the contention that the U-boat war was not that serious. LOL
Well you can laugh. Me, i prefer to see the data. I've posted numbers from Blair's book. All you've posted is raw tonnage which is yes, well known, and some of Churchill's quotes on his fears. Blair, love or hate his writing style, researched all the convoy and uboat patrols and compared them with economic data for the USA and Britian at the time. I've asked you repeatedly over and over to show the data that backs the negative commentary you've gone to pains to post about the author. To this date you have not.
I guess all these other historians are flighty individuals running around waving their hands in the air whenever the word "U-boat" is mentioned.
I have no idea who "all these other historians are" and have no need to critisize their work. When all I see are quotes from Churchill and the daily paper of the time talking grim about the Uboat war which i never said was anything less than a struggle for life, When all i see are comments that the Uboat war was serious and that heavy losses were reported in raw tonnage yep, the description fits. None of these trappings indicates that Britian's lifeline was in mortal danager of being severed. If Blair is the first author to truely attempt to delve into the real effects of this popular subject, that does not automatically make him wrong. What would make him wrong is equivilent data that shows that Britian was teetering on the edge of destruction and that most of her loaded ships were being sunk before reaching harbor. But that appears to have not happened.
To paraphrase Tweedy Bird: "I did, I did. I did taw a U-boat."
I'd like to see a Uboat someday. :)

No one said the British were starving, even though rationing was instituted, and everyone had to grow gardens. Even so, just three weeks interruption of the convoy system would have resulted in dire shortages.
Ok, you admit they wern't starving. It also appears their economy wasn't grinding down either. As for "interruption" of the convoy system. It never happened during the war. According to the data, it never came close to happening. I think it would take a hell lot more than a few more boats to create that total or near total embargo.

The British Prime Minister, Winston Churchill, in a broadcast on 27th April 1941, made clear that the most important theatre of the war for Britain lay in the Atlantic:

"Still, when you think how easy it is to sink ships at sea and how hard it is to build and protect them, when you remember we never have less than 2,000 ships afloat and 300 to 400 in the danger areas, when you think of the great armies we maintain...and the world-wide traffic we have to carry, can you wonder that it is the Battle of the Atlantic which holds the first place in the thoughts of those upon whom rests the responsibility for procuring the victory?"
Nice speech. Again all this proves is that Churchill's first obsession was the Uboat. No doubt he was right to focus on the threat. When your an island nation dependant on maritime trade, i think that produces a far different perception of priorities vs say, a continental power that if push came to shove, could survive having half it's merchant fleet shot out from under it. Who knows, maybe thats why King downplayed the warnings from the British which helped make DRUMBEAT a reality. Had Britian not focused on the threat.....maybe they would have lost their lifeline. But they did focus on it....obscessed on it might be the better word....and it appears they never came close to losing it.
And while convoying did undoubtedly reduce sinkings and save lives, the introduction of the convoy system led to a temporary but critical one-third reduction in the quantity of imports reaching Britain, a fact which caused Churchill much concern.

In addition to a one-third reduction in imports, there was also the 2,500 ships that had been sunk in the first two years of the war.
Much of which was quickly replaced.....meanwhile, Britian's economy made the adjustments, reduced it's need for imports and chugged on, as did the British people. Nothing new here......raw tonnage #'s Got em....thanks.
War is waged by much more than having a few carrots and potatoes to eat. It requires prodigious amounts of oil, metals, parts, tanks, aircraft, ships, factories, money etc, etc.

And every ship sunk, places the recipient in a far worse situation.
That is the oft held contention, if one assumes that each ship sunk was loaded. They were not. Britian continued to produce the tanks, parts, aircraft etc etc etc. When losses from the land battles exceeded that production they turned to the USA for help.

In early 1941, not only was Britain running out of gold and cash (in fact it couldn't even pay the US for any of the armaments it was building), but the ships the USA was building would only meet half of Britain's shipping requirements due to losses sustained (page 692, Gilbert's "Churchill").
Britian was running out of gold not meerly because of uboat losses, never rich to begin with after WWI gutted the treasury, the land based losses and the BoB and the damage/costs it ensued would all have combined to create a money starved government.
It was a just a figure to illustrate my point. Relax. [/B]


I'm always relaxed :) well your point seemed to be indicating that only a "handful" of uboats created a catastrophe when in reality it was rather more than that. Perception is a powerful tool and can readily distort.

Hi, I don't think I've added any French ships. (But I'll bet there were French ships used by allies)

The Polish ships for example. Some of these were at Dunkirk, others hauled material to North Africa for the USA later on.
Norway had one of the largest merchant marines in the world. The fact that over 500 Norwegian ships were sunk after Apr 9 1940 while in the mid atlantic shows a considerable number of Norwegian ships went into allied service. I even saw a WW2 Poster thanking the Danish merchant marines for continuing to man their ships.
You do the math. The U-boats sank enough ships to defeat Britian.........except the British must have gotten a large number of ships from some place (and as you point out new production does not come close in 1939 and 1940)

The 233 Norwegian tankers were used the entire war. They were critical to Allied planning. I think if I find and post the total tonnage Britian recieved as a result of other neutral countries going allied it will dismay you.

After Dec 7 1941 it is pointless to debate. The only question is could Germany have defeated Britian in 1939-1940.
The answer is yes. But only by preventing neutral ships from crossing over into the allied camp or sinking 3 times the tonnage they sank.


PS it takes till 1943 for allies to pass sunk tons with new tons only if I use the lowest set of numbers I find. And I should point out these numbers are only USA production not allied production.
If I use the higher totals I find then in 1942 the USA built 10MT new (not allies just USA) But to help the U-boat cause I used the lowest total I could find. ( this is 28 months after war begins allies are clearly out producing lost tons)

50% of all shipping losses were suffered between 1939 to 1941, or 2,500 ships. According to Blair, this type of threat was over-blown.

I do not doubt that many ships in convoy reached their destinations, and neither do other historians. I have mentioned this before.

The problem is, even though thousands of ships are sunk, especially before 1942, Blair does not consider this to be a serious threat by U-boats.


Not if Blair's info on Britian is correct.

I have seen Blair's info. Many different sources have varying numbers - some sources have twice the numbers that Blair uses. So we are to suppose that Blair's numbers are correct? Then again, how are we to check his facts, when he provides no footnotes!


I have no idea who "all these other historians are" and have no need to critisize their work.

What would make him wrong is equivilent data that shows that Britian was teetering on the edge of destruction and that most of her loaded ships were being sunk before reaching harbor. But that appears to have not happened.



I have provided info and quotes from reliable sources and highly qualified academics. The author of Churchill's biography, who was a professor at Oxford, spent 26 years completing the 8 volume work of his life. They at least provide sources for their information, something Blair fails to do.

What is it about the fact that 2,500 ships being sunk between 1939 to 1941 that you do not understand?

I also guess the statements made by one of the greatest statesmen of the 20th Century (Churchill - who was briefed daily on all war activities and who was a scholar in his own right, having written two dozen history books) carries NO weight - LOL

Ok, you admit they wern't starving. It also appears their economy wasn't grinding down either. As for "interruption" of the convoy system. It never happened during the war. According to the data, it never came close to happening. I think it would take a hell lot more than a few more boats to create that total or near total embargo.


No one said they were starving. This is something you added. Although, a 3 week interruption of convoys would have led to food shortages.

If the country you currently live in is always just 3 weeks away from starvation and food shortages, would you not consider this to be a crisis?

Heck, you might even become obssessed over food - hehe

Who knows, maybe thats why King downplayed the warnings from the British which helped make DRUMBEAT a reality. Had Britian not focused on the threat.....maybe they would have lost their lifeline. But they did focus on it....obscessed on it might be the better word....and it appears they never came close to losing it.


Obessessed. Hehe - Yeah, when you're all alone, fighting for your very existence, I guess you can get "obssessed" - :rolleyes:

Never came close to losing it? If Blair is the only book you have read on the U-boat war, then I can understand your thinking.

well your point seemed to be indicating that only a "handful" of uboats created a catastrophe when in reality it was rather more than that. Perception is a powerful tool and can readily distort.


The fact is that only a handful of U-boats were at sea for any length of time until later in the war. And yes, a relatively small number did inflict huge losses.

For example, in June, 1940 there were only 21 operational subs.

In April, 1941 there were only 35 operational subs.

This disproves Blair's thesis, since, if Hitler had built more U-boats, the losses would have been even higher in 1939-41.

Hi, I'm learning a lot about U-boats and merchant ships.

UK started war with 21mT of merchant shipping. Needed yearly imports of 43mT after rationing. (Every ton of shipping sunk = 2T of goods/yr. lost.)

1939
U-boats sink 755,000 tons British replace (new builds) 320,000 tons.

Polish merchant fleet of 54 ships 188,000 tons escapes to Scotland (320+188=508k tons) (These ships carried over 5 million tons during war)


So in 1939 Germany was plus 247k tons 21,000,000-247,000

1940 to follow

1940

U-boats sink 4million tons

1.2 million tons new builds

Norway
233 Tankers fell under Allied control after the Apr 9 1940 invasion of Norway. These ships were to prove vital during war. Over 500 Norwegian ships would be lost during battle of Atlantic. (over 1000 ships went "Allied") using 2.5k I'll add 2,500,000 tons for these and 582,500 for the Tankers (and I know this is way below real tonnage)

Denmark
800,000 tons went to Allies after Denmark was over run.

4,000,000-5,082,000 Germany is behind 1,082,000 for 1940 and 835,000 tons overall. (British begin Sept 39 with 21MT begin 1941 with 21,835,000 ton)

1941 to follow


My figures indicate that in 1939 Britain had the biggest merchant fleet in the world of about 3,000 ships, totaling 17 millions tons, and not the 21 million you have indicated, which means the British lose 4 million tons.

I've done some digging, and the numbers roughly correspond to what you have written. I was mainly interested in the sources you used, since this type of info is difficult to come by.

Again, all this info disproves Blair's thesis: Since, as you rightly mentioned, "The U-boats sank enough ships to defeat Britian.........except the British must have gotten a large number of ships from some place (and as you point out new production does not come close in 1939 and 1940)", then the U-boats posed a great risk to Britain's survival.

The fact that all these other ships came over to Britain; the fact that Hitler didn't concentrate on U-boat buildiing early on; etc, etc, does not diminish the threat the U-boat posed.

Since Britain started the war with 3,000 ships; and since by Dec/41 the Germans had sunk 2,500 ships; then it clearly indicates that Britain (if left by itself without the benefit of other countrys' shipping or new construction) would have been left with only 500 ships.

In other words, in the first two years of the war, the Germans sank the equivalent of almost the total number of pre-war British merchant shipping!

This is indeed a crisis.

And again, this only serves to disprove Blair's contention that the U-boat threat was overblown and did not pose a strategic threat to Britain before 1942.

The fact that the USA entered the war; the fact that other countries' merchant ships went over to Britain; the fact that few U-boats were initially built; and the fact that Hitler turned east, rather than dealing Britain a death blow, can only be considered to be some of the fortunate twists and turns of history that fate seems destined to hand out from time-to-time.
