Hi, Some where we have several different sets of numbers.
My sources give around 1500 ships total sunk by other then sub during entire war in all theatres. (So using the 1200 by 41 figure we are left with 300 for 42-43-44-45 ) Somethings gotta give.
We all have to agree on a set of numbers and all use it.
(I have nothing showing 1200 ships lost via other then sub before end of 41 and I'm going one day at a time. )
Ok let me try this and see if it floatsOriginally posted by Mogami

My main source World War 2, A Statistical Survey, John Ellis 1993
lists nearly every conceivable topic. So I'll give you 1939, 1940 and 1941 numbers.
Merchant vessels lost all causes
1939 = 221
1940 = 1059
1941 = 1399
Total = 2679
It then goes to list losses by cause but does so in percentages
then by doing the math we should be able to arrive at a very close number
1939 = 221
Subs 55.8% = 123 vessels
Aircraft 0.4% = 1 vessels
Mines 34.8% = 77 vessels
Surface 8.1% = 18 vessels
Other or Unknown 0.9% = 2 vessels
1940 = 1059
Subs 54.8% = 581
Aircraft 14.5% = 154
Mines 12.8% = 135
Surface 12.8% = 135
Other or Unknown 5.1% = 54
1941 = 1399
Subs 50.1% = 701
Aircraft 23.5% = 329
Mines 5.3% = 74
Surface 11.2% = 157
Other or Unknown 9.9% = 138
So given these numbers we come up with
Lost to Subs = 1405
Lost to Aircraft = 484
Lost to Mines = 286
Lost to Surface Vessels = 310
Lost to Other or Unknown = 194
Total = 2679

The approxiamte total of ALL Allied ships sunk (by all causes) between 1939 to 1941 is closer to 2,500 ships.
The total number of ships sunk in all of WWII is closer to 5,000.
Here is a site that gives several comparisons:

Here is another site that gives an exhaustive month by month account of all Allied ship sinkings throughout the war:

No NO NO. I didn't say by all causes I said by all causes other then submarine. On your page they need to learn how to add
(The totals make no sense.)
Lets not mix our numbers. (from your web site)
Well I tried to use that first table but none of the numbers add up to what the totals are.
I used the bottom table (It had the highest ship sunk totals)
Can't use it. In fact none of these tables are close to one another from 39 to 45.
On one page it goes from 50 ships sunk by U-boats to 212 all sunk in 1939 by subs or in Atlantic.
This is hopeless. Can't anyone agree
"SS Blah of XX tons was sank by XXXX on blah blah date???
I will say more merchant men survuved being sunk then I first supposed. If 85 percent of the prewar fleet was sunk and only 30 percent of the prewar sailors were lost. (and supposing the number of ships went up (It does not matter if a ship was sunk. The merchant marine had to get a new crew for the new ship. But the total crew lost was only 30 percent of pre war number)

Hi, Ok. But these numbers don't really tell us what we need to know.
For instance. I've found ships sunk in Atlantic by U-boat are normally at least twice the tonnage of ships sunk else where by other then sub.

Ok I think I now know what you are looking for...
September 3 1939
U-26 Lays minefield which sinks 3 ships of 17414 tons
U-27 sinks 2 ships of 624 tons
U-28 sinks 1 ship of 4955 tons
U-29 sinks 3 ships of 19405 tons
U-30 sinks 2 ships of 9625 tons
Etc. Etc. Etc. Etc.
If this is what you are looking for I have the info but it going to take a while and I mean long while to compile it all thru 1941

Oh now we have a new set of numbers. Ships sunk by other causes includes trawlers (often very small under 300t) and there were 6k of them in WW2. (They were used for coastal traffic. Many were used in ASW roles. My source (a trawler page) states there were 6,000 trawler crewmen (and women) in 1939 on 600 ships and by wars end there were 66,000 crew on 6k ships.
These trawlers get listed in the sunk ship totals but were not part of 3k merchant fleet. (Many non U-boat non Atlantic ships sunk were this type)
This results in a problem
a U-boat torpedos and sinks 1 9kt ship in mid atlantic.
a Ocean tug of 80t hits a mine and sinks
a JU-88 bombs and sinks a trawler 300t
totals for day 3 ships 9380t. But only the 9kt ship really impacts the overall picture.

Hi, The trawlers did not operate any where U-boats actually did.
The U-boat was confined to the mid Atlantic gap. After the fall of France they outflanked the RN and had bases that allowed them the range to operate outside aircover. We don't find too many U-boats operating in the confined waters. (They also hit mines. )
Of course the RN did not know this and maintained ASW patrols.
The trawlers also fought E-boats and mounted AA.
When you look at ships sunk UK waters you don't find too many U-boats after mid 40. But the bulk of the ships lost in these waters also did not belong in the vital ocean going merchant catagory (where they are always quoted)
Only ships capable of trans ocean movement should be listed in our study.
These are the ships the U-boats were after. We don't need to include "U-** surfaced off Norway on Apr 7 and sank 6 Norwegian fishing boats and MG'd the crews and later list these boats as part of a 5k ship sunk total.
