Looks like we are not "all together".

Sorry to burst your bubble Mogami, but NO ONE said the U-boat (as it was organized in WWII) would have defeated Britain all by itself.

My part of the discussion in this thread centered round two things:

1) Blair's contention that the U-boat threat was over-inflated, and did not pose a threat to Britain.

I have shown that it did pose a threat, and it took the Allies 4 years and considerable resources to defeat it.

As I stated previously, this portion of the discussion, for me, is closed. I have satisfied myself with the information.

2) Germany could have defeated Britain before December 1941.

In saying this, the U-boat would have been ONE tool in that mission. But as it was originally conceived and put into place, it could not accomplish it on its own.

If Hitler had put the full resources of Germany to work to defeat Britain, he, in all likelihood would have accomplished it.

Here are just a few of the possibilties that were open to Germany before December 1941:

1) Failure to produce large numbers of U-boats leading up to 1939, and afterwards.

2) Failure to bag all the Allied troops at Dunkirk (over 330,000 were allowed to escape). Guderian was ordered to stop.

3) Failure to seize North Africa, instead of attacking the USSR.

4) In the Battle of Britain, the failure to continue the policy of bombing British airfields, radar stations, etc

5) Hitler's incredibly stupid declaration of war on the USA in Dec, 1941.

6) Failure to gear the economy for Total War.

7) And on, and on, and on. . . .

The failure to produce more U-boats is just part of the over-all picture of the lost potential Germany had to achieve greater success.

And no, I do not intend to be drawn into a debate on all of the above.

This is to make sure that we are all on the same page.

Anyway, have fun with all your research. I'm heading to the beach :D

You should be a politician Von Rom.....you have changed slightly, and not so slightly your orig contention, dont back it up with the data specifically asked for, and then claim "victory" over your fellow debators and author Clay Blair

I do not recall Mogami, Pry, or myself ever saying that the Uboats were "no threat."

The goal here, is to provide what you were unable too: proof of Britian's true economic state/condition by 12/41.

U-boats

Post by mogami »

Hi, I think we are all aware of the fact that U-boats as organized at the time would not defeat Britain alone. (Since this is a fact)

The survey seeks to establish exactly what Germany by all means accomplished. We are seeking to know the amount of material on hand in Britain at any time. The number and tonnage of merchants on hand at any time.

After we have these base points we will then know exactly how much increase in damage the Germans would need to inflict to put Britain in an actual "crisis" (Or if and when this state was ever in fact achived. And how long it was maintained)

I have no bone to pick. I only wish to know for certain myself the true record of events. No matter what the data reveals I will be content to have attained a better understanding of history.

Example of Norwegian ship in British service.
M/S Abraham Lincoln NS
Fred Olsen & Co., Oslo 5740 gt
Built in Odense, Denmark, delivered in 1929.
Captain Sverre Holmsen. Made it safely through about 50 Atlantic crossings (287,000t)
Abraham Lincoln was in Convoy HX 167 which left Halifax on Dec. 27-1941 (1st convoy?)

I was not going to make another post in this thread, but I cannot let these statements stand.

1) I have not changed in my stand. Nowhere throughout this entire thread will you find any comments made by me that the U-boat, as it was organized in WWII, could win the war all by itself.

2) Almost every opinion I have stated in this thread has been backed with quotes and sources by some of the best academics and leaders I could find. And I have stacks of books at my disposal that I have not even touched yet.

3) I have shown the fact that Blair fails to include in his book, 1,400 Allied ships sunk by other causes, which defeats his own argument according to HIS own criteria and statistics. YOU have his book and can read the pages I indicated in my previous post on this matter.

It was over HIS contention that the U-boat threat was overblown, threat inflated, etc, etc, that this discussion centered.

4) I never claimed "victory" over anyone, least of all the other people in this discussion. In fact, after I found those allied ships were missing from Blair's data, I said that you guys shouldn't waste "your valuable time" debating something which this omitted data defeats.

I just wish I had found it sooner - it would have saved us all a lot of typing - LOL

5) I have indicated in numerous posts, with sources from qualified academics, including Blair himself, about the state of Britain's economy. These have NOT been my opinions.

If you guys think you can do better - then go to it. . .

No problem Mogami. I generally respect your opinion. And I am also interested in the data you find.

BTW, the Norwegian ship AL is an example of what I had mentioned earlier. Although Norway is close to Britain, the fact that its first convoy of supplies may have been in late Dec 1941, indicates the long times periods involved between a ship "coming over" to the British side, and its actual use in supplying Britain. In this case it MAY have been a year and a half.

So additional total tonnage and ship numbers don't mean anything if we don't know where those ships are and when they became "useful".

missing data

"4) I never claimed "victory" over anyone, least of all the other people in this discussion. In fact, after I found those allied ships were missing from Blair's data, I said that you guys shouldn't waste "your valuable time" debating something which this omitted data defeats."


Hi, It has not been established that this missing data shows anything other that more ships were sunk then this fellow quoted in his book. If these extra (or missing) ships were not related to the maintenance of material levels in Britain then there ommision means nothings (since we will omit them as well except to note their loss in the ship totals. If they contained tonnage relevant it will be included. One way or the other we will know the exact facts. A lot of conjecture concerning ship totals has already been revealed as meaningless.

The Royal Navy lost 381 ships in 1939 and 1940. Only 16 of these had any direct impact on the supply levels. (They amount to almost 3 million tons of material not being delivered in the remaining period of the war)


I'm going to work through 1941 today. So I will have final data on the Royal Navy during our period of study.

1941 Royal Navy first pass

350 ships sunk 10 ships counted towards survey

1939-1941 totals 730 ships 26 keepers

Still need to sort out those sunk by U-boat from those sunk otherwise.

Mogami:

The way your study is being conducted is flawed. It is being conducted by your definition of what should be included.

Your say that the Royal Navy lost 381 ships in 1939 and 1940. Yet only 16 of these had any direct impact on the supply levels.

This type of thinking is wrong. Let me explain.

Many of these ships (destroyers, trawlers, etc) played a vital role in defending against U-boats and protecting merchants and harbours, etc.

In other words:

What is more important:

"The bomber or the fighter escort?"

What is more important:

"The merchant ship or the convoy escort (destroyer)?"

Since even Blair contends that most ships that were sunk were unescorted ones, it follows, that it was with the help of the escorts that merchants made it through the U-boats in one piece.

This means that the destroyer is as valuable as the merchant, since you cannot have one without the other. Well you can, but then the number of your merchant sinkings go up, involving more shipbuilding, etc.

This is why the allies had to divide their shipbulding priorities between destroyers and merchants and minelayers, and minesweepers, etc, etc.

Almost all studies of Allied ship sinkings INCLUDE lost destroyers, aircraft carriers, etc, because these warships were part of the Battle of the Atlantic, as it was their job to protect merchants AND sink U-boats. A lost destroyer is a cost of the convoy system, just as much as the merchant ship is.

You cannot have protected convoys without destroyers and escorts.

You cannot have a harbour free of German mines without minesweeping trawlers. This means that destroyers and trawlers must be commissioned instead of more merchants.

If you don't have destroyers, then you don't have protected convoys, and therefore the supplies don't get through.

If all destroyers are lost, then sinking merchants becomes easier. This is why Britain wanted those 50 WWI destroyers so bad.

Even trawlers performed a vital service by attacking U-boats attempting to lay mines near ports and harbours where merchants might run into them.

A lost trawler means that the British must forgo building another merchant because they have to re-fit another ship to serve the same puropse.

This is why the Germans also attacked and sank these "warships". They knew less destroyers, meant more unprotected merchants. Less trawlers, meant more mines could be laid.

Without these additional ships included in your "study" your data will be fatally flawed. It will be interesting, but flawed.

All researchers have understood this. Even Blair does.

I agree that some ships like blockships, etc shouldn't be included, but many of the others should be.

Let me cite an example from UV. We all know how important supply is in the game. That merchant ships are important. But who in their right mind would send these ships into enemy held territory without heavy escort and carrier cover? This is all part of the cost of getting the supplies through.

Ship totals

Post by mogami »

Hi, I don't think you understand our line of reasoning.

In previous posts we have seen quotes like

Britain began with 22,000,000 tons of shiping.

In 1939-1941 she lost 2500 ships totaling XXXX tons
She was on the brink of collapse.

Then we go and examine the facts and find at least 700 of the 2500 ships had nothing to do with carrying supply to Britain.

That the tonnage subtracted from the total is not even the same ships used to arrive at that total.

Since this is not a live event it does not matter for our purpose.
(It would be important to keep track of escort loss if this were taking place at this time. It would influence planning. We will even note when a Allied ship is lost as a result of escort shortage. however it is not important for knowing what the tonnage on hand on any date was)

She was on the brink of collapse.

Then we go and examine the facts and find at least 700 of the 2500 ships had nothing to do with carrying supply to Britain.

That the tonnage subtracted from the total is not even the same ships used to arrive at that total.

Since this is not a live event it does not matter for our purpose.

OK, fair enough. Just pointing out what most researchers have discussed.

But it must also be remembered that many of those 2500 ships sunk helped to keep the supply trail open, and so were also vital, even though they may not have been in the original totals.

Von Rom.....i promised to do my part and not keep salvoing back and forth needlessly so i'll just let readers of the thread decide for themselves regarding the variability of your "stand" and the other items you've recycled.

Regarding your claim though that you've provided the economic data I requested; ***WHERE?**** All i've seen you give is raw tonnage data, followed by #'s of ships sunk, followed by the total level of imports.....usually attached with dramatic adjetives about how bad it was for Britian......none of which tells us what we want to know about Britian's *actual* state in terms of her vital industries and stockpiles.

Had you provided this, then we wouldn't still be here trying to piece the puzzle together. Had it shone a Britian on the verge of defeat, I'd have said Blair was wrong in his contention that the Uboats did not come close to achieving ******strategic, and decisive victory******* and hence their threat was overinflated and we could all go to the beach together!

For what it's worth, i dont think counting ships will do the job either. Roughly 2500 ships were destroyed, we know this. We also already know that her merchant fleet ended 41 *bigger* than it started in 39 which makes dramatic talk (by you) of how much % of the prewar British merchant fleet those 2500 ships represent not only misleading, but liable to being the example of the "threat inflation" you say you've proven is false. LOL You also have carefully skirted the fact that this was hardly a one sided blow and that Britian struck back sinking 35% of Germany's *wartime* (not prewar) Uboat fleet up to that point.

The only question worth pursuing that remains is : what is the true state of Britian's economy, based on her stockpiles, and how well her industries are running......as i've said many times....were they at the brink? were they critically short of what they needed? If they were not.....then i'd say thats all the proof needed. Noone denies the Uboats, oh sorry, the Uboats and the entire German armed forces :) "Hurt" Britian, the "question" is, how much did these Uboats hurt in real terms to a Britian now running on war economy with it's belt tightened and the hatches battened down......

No quotes from famous figures

No "opinioins" from authors about how bad the situaiton looked or felt.

no references to the BoB, Dunkirk, or WWI.

data......tabulated would be nice. showing the state of Britian's economy.

I fail to see why this simple request is so hard fullfill?

But if we just use the total number of ships sunk, it still begs the question as to why Blair would omit this rather large number of Allied ships sunk by "Other Causes".

Taken together, 2,500 Allied ships sunk between 1939 to December 1941 by all causes represents the equivalent of Britain losing 83% of its pre-war merchant fleet (of 3,000 ships).


Hi, Are we showing you somewhat at least that these 2500 ships were not in fact 83 percent of prewar merchant fleet? (since I've shown over 700 of the 2500 were not even merchant ships)

As far as their being important to keeping supply line open I agree. I also think they did their job. I'd prefer my escorts to be sunk rather then my merchants.

As I mentioned in my last post to you - this subject of debate is CLOSED.

I have already found the information I need to explain why Blair's argument is faulty.

Mogami:

Hi

I said the 83% is equivalent to the total of British pre-WWII ship totals. I know they are not the same ships.

It is the equivalent.

My disagreement is not with you; it was with some of Blair's findings. You have nothing to prove.

It is admirable that you are doing this work.

However, you are doing this survey based upon what you have subjectively defined will be included in it. That's your privilege. It's your survey. But the results will hardly be "scientific".

As you know, convoys work. That's why the British built escort ships, and that's why the Germans tried to sink them.

It costs resources to build escorts, just as it costs resources and supplies to build merchants. For each one of these ships that is sunk, another must be built to take its place. In addition, if the crew goes down with their ships, then new crews must be found and trained, and fed and clothed. All of this is the cost of war; of convoying; and of the struggle for the Battle of the Atlantic.

How else were the allies going to defeat the U-boat? Ram them with merchant ships?

The allies poured a lot of resources into building escort carriers, destroyers, sonar, etc to help sail the ocean to hunt for U-boats. This is all part of the cost of getting supplies through and of defeating the U-boats and Germany.

There is a cost for building destroyers - it is the cost of giving up building an extra merchant ship. Plus, some of the supplies that merchant ship is carrying is in part helping to build some of those escorts.

Why do you think there was a "shortage" of ships among the allies? Do you think all the authors of these books make this stuff up? It's because there were competing demands for SHIP TYPES, to do all types of different jobs. All the shipyards weren't building the same type of ships. Look at all the ship types in UV and WiTP. There is a cost involved whether we like it or not.

To his credit, Blair understands all this and has factored this into his data.

There is so much information that must go into a study of this type, that simple numbers will not do.

For example:

In 1939 we know there were 3,000 British merchant ships of 17,000,000 tons. However, of these 3,000 ships, how many were stationed in the Pacific? How many in the Atlantic? Were they ALL operational at the same time? or were many of them "dry-docked? How many were under repairs? How many were being converted into troop ships? Etc, etc. . .

Well, you know what I mean.

All U-boats were not operational at the same time. It is the same with these 3,000 ships. One simply cannot say,"We have 3,000 ships, therefore we XXX capacity." Simply doesn't work that way.

Using UV as another example:

You have 2 BBs and 2 CVs at Noumea. You learn that in three months you will get 1 BB and 1 CV from Pearl. Even though on paper you have 3 BBs and 3 CVs in existence, you know that in reality all you have operationally, are your original 2 BBs and 2 CVs, and must plan your operations accordingly.

This is also the way it works with merchant ships, etc.

It is a very, very complicated thing to work out, and will simply not yield any relevant results from a quick study of this type.

Heck, economists have studied this question. What a job that would be. . . ack

I think playing UV would be far more enjoyable. :)

In the final analysis, Mogami, you have nothing to prove. Either does pry or Nikademus. We all see things a little differently. Hopefully, because of our friendly discussions, it will spur others to do some extra reading on the subject.

Cheers!

Mogami:

I also wanted to add that you have provided a lot of important information regarding the number and types of ships that have been sunk.

I think it will give many of us more to think about when we see numbers of ships listed as sunk.

I would also say that some ships may be worth more than others, but that they are all valuable in getting the job done.

Regarding the number of merchant ships being available: I just thought of something.

I will use a simplified example to illustrate:

Say Britain has 3,000 merchant ships. Let's assume they are ALL available for our convoy purposes. And let's assume they are all available for the Atlantic.

Next, let's assume we have a convoy route setup between Halifax, NS and Portsmouth, England. Let's assume it takes 30 days to complete the trip one way.

This means that fully half of those 3,000 ships (1,500) will be empty at least 6 months each year (they are empty when making the return trip from Portsmouth to Halifax).

I think just this one example illustrates how shortages could occur even though there appear to be lots of ships available.

Cheers!

VR, This may seem strange to hear but to a point I agree with parts of what you are saying here...

1st of all let me get the part I disagree about out of the way
Your number of merchant hulls (3000) for the UK at the start of the war is too small by half. I think we have all agreed (have we actually agreed on something after all this time.. ) the starting tonnage is 17,000,000 give or take a bit. No offense but I can not accept this 3000 number because that would make the average vessel size around 5500 tons each this is far too big. As my "Little Project" has been showing the average vessel size is closer to 2500 tons. I believe a starting number of 6000-6100 vessels is correct. I know your sources say 3000 but those numbers do not jive to the data being shown by Mogami and myself.

Now to the part I do Agree with (At least in principal) You are absolutly correct in your suggestion they would not all be available on day 1, most would not be available until October - November. Now that I have your undivided attention i'll explain why, The British merchant Marine was privately owned and plying trade to the 4 courners of the world. They were Militarized on Sept 2 1939 with UK's declaration of War on Germany and would have to assemble in British or Canadian ports for convoy duty. This would take time... So the total fleet could not have possibly been brought to bare until Late 39 maybe even Early 1940. One has to understand from the start that the required amount of vessels were already on steady runs to the UK keeping her supplied the excess capacity and there was a large one would take time to assemble in order to pitch in and start bringing in additional supplies and materials. This is a point I think everyone is missing not every English merchantman was bringing supplies and material to the UK, they were trading all over the world.

I also agree that these ships would not be available 100% of the time, general upkeep overhauls and yard time would keep some out of action at times. UK did not need 100% she had excess capacity.

Your statement about being empty half the year is also to a point correct, The only time a ship will willfully deadhead is in time of war... in real life if they are not loaded then they are not making money. If you assume all vessels travel at the same speed then what you say is correct but !!! Part of how they dealt with that was by forming Fast and Slow convoys the faster ones would lap the slower ones and as a result MORE was being delivered than if all were traveling at the same speed. Think about for a bit i think you will see what i mean.

To give you an example look at it like a car race, if all were going the same speed then all would be bunched up on the same lap on the same part of the oval. Now with faster cars they lap the slower ones and cars are all over the oval so say the race is 100 laps the slowest cars cross the finish line 100 times but the faster ones got there 2 laps ahead of the rest but if they had kept going until the others finished their 100 laps they would have done 102 a crude example but i think you can get the idea.

Anyway I also think this research is interesting will it prove anything no but i think we can come away from this with a much better understanding of UK's economic situation and if she was in as much trouble as your take is or Mogami, Nick and myself's that she was not in that bad a spot.

The one thing we all seem to forget is that history is always written by the winner and they ALWAYS slant that history to shed the brightest light on their side. So MR. Blair can be forgiven for his biases as can S.E. Morrison, great writer i own the 15 volume set of his history of WWII and read every volume cover to cover many times but still roll my eyes at some of the things he has to say.

had a little family problem today that I had to deal with I'll get my part finished over the weekend, I also found another source that i forgot I had that does a much better job of naming ships when sunk, I'll use it to expand my current data.

Stop The Presses New Info Discovered

Post by pry »

Just ran across a very important paper that just might put this thread to bed once and for all.

I urge anyone who has an interest in this thread to download the .pdf file Especially Von Rom, Mogami and Nikademus

1 meg, 44 pages with tables and sources
http://www.jmss.org/2003/spring-summer/ ... cdfai2.pdf

Central Thesis is this

Lost wartime imports reduced British military output only by a very small amount. In the face of VASTLY REDUCED imports, adjustments within Britians import program and it's larger economy supplied the war economy with MORE steel, MORE of the most important non-ferrous metals, MORE of some non-metallic materials, MORE staple crops, and MORE of some other foods than Britian had comsumed in peacetime.

Although Britain had to make do with less timber and less of some other non-metallic materials and foods, these losses did not significantly hinder it's war economy. Even if it cannot be precisely quantified, the immediate cost of reduced imports was very small.

Well, I don't make anything up, especially something as important as the amount of British pre-WWII merchant shipping.

You and Mogami say the British had 6,000 merchants? What is your source for this amazingly high number?

Nowhere, in ANY source I have checked, has the number of British merchants come anywhere near 6,000. I would really double-check my numbers if I were you.

The statistics I used come from Blair himself:

Page 99, 1st volume:

Grand Total of ALL British controlled shipping in 1939 = 2,999 ships of 17,784,000 GROSS Tons.

Blair's source for this information is Hancock (1975) - a well-respected international statistical source.

Remember not to confuse GROSS tonnage with NET Tonnage. Gross Tonnage is LARGER than NET Tonnage. This may be why you think the size of the hulls is too big. It's simply a different way of measuring the SAME THING.

As you can see your study is ALREADY in error.

Now to the part I do Agree with (At least in principal) You are absolutly correct in your suggestion they would not all be available on day 1, most would not be available until October - November. Now that I have your undivided attention i'll explain why, The British merchant Marine was privately owned and plying trade to the 4 courners of the world.

Part of how they dealt with that was by forming Fast and Slow convoys the faster ones would lap the slower ones and as a result MORE was being delivered than if all were traveling at the same speed. Think about for a bit i think you will see what i mean.


The example I used was very over-simplified to illustrate something that most writers seem to have diffculty in explaining. But I think it helps us to visualize the problem better.
Anyway I also think this research is interesting will it prove anything no but i think we can come away from this with a much better understanding of UK's economic situation and if she was in as much trouble as your take is or Mogami, Nick and myself's that she was not in that bad a spot.


True up to a point.

While Britian was JUST able to maintain itself (Blair states from 1940 imports dropped drastically for each successive year), it is very clear from my simplified illustration what would happen if the U-boats were able to stop or impede the convoys for 3 months, or sink enough merchants to cause a further drop in supplies getting through.

It was a very tenuous lifeline. Everyone agrees on this. But no need to get into all this again.
The one thing we all seem to forget is that history is always written by the winner and they ALWAYS slant that history to shed the brightest light on their side. So MR. Blair can be forgiven for his biases as can S.E. Morrison, great writer i own the 15 volume set of his history of WWII and read every volume cover to cover many times but still roll my eyes at some of the things he has to say.


This is also true to a point.

This is why certain topics make for great debates.

The reader should be aware of biases if they are present. While much of Blair IS informative and worth reading, the reader should also be aware of the fact that he neglects to include data into his statistics. He also spends 269 pages defending King's decisison not to escort merchant ships in 1942, which led to the easy sinking of 585 vessels along America's east coast.

People can agree with Blair, or they can disagree with him. Hopefully, whatever decision they reach is based on informed opinion.

Cheers!
