Submarine Losses in the Mediterranean

The following table is courtesy of Erwin Sieche ( The sources consulted are listed at the bottom. Erwin notes that:

I am especially indebted to Admiral Attilio Duilio Raineri, Italian Navy (ret.), for providing information and corrections.

Note that putting a hyphen between letter and number is US practice; the Germans only left a blank. Historically correct is U 21 instead of U-21. The same rule is for much of the European ships with numbers, like British submarines (e.g. E 21 instead of E-21, Italian subs e.g. W. 4, Italian MAS boats; also all other German designations, eg. for destroyers or torpedo boats, eg. Z 38 or Z 38). The hyphen came into German literature by bad translations from US books.

Further information from Erwin Sieche:

Imperial Germany had sent submarines to the Mediterranean, but in 1915 it was not at war with Italy. It was only a matter of time until the first problems of international law occurred. Therefore it was decided to enlist the German submarines operating in the Mediterranean formally into the Austro-Hungarian navy and they should fly the A.-H. flag when attacking. The A.-H. boat numbers are given in brackets.

The reader consulting all these books will note that they differ in some points. Without going back to the original files it is not possibly to find out the historical throuth after eighty years. It is also remarkable that the firstnames of some of the submarine commanders are not told in the above mentioned naval reference books. In some cases we do not even know their family names.
