This may already be a redundant topic; there are so many threads on the Seehund. However, I couldn't find what I was looking for, so here goes. I've checked with three different sources on tonnage sunk by the Seehund and have found three different estimations. The Historic Naval Ships Association says, "Operated by two men and carrying two underslung torpedoes, the Seehund was used very effectively in the waning months of World War II, sinking over 120,000 tons of allied shipping." http://hnsa.org/ships/seehund.htm In the book Wolf Pack by Gordon Williamson he says, "It has been estimated that up to 90,000 tons of enemy shipping were sunk in operations using the Seehund." Williamson even includes uboat.net as an Online Research Resource, yet the website gives another number for sunken tonnage: "From January through April 1945 the Seehund boats went out on 142 sorties, lost 3 of their own and only sank 8 ships for a total of 17,301 tons and damaged 3 for 18, 384 tons." http://uboat.net/types/seehund.htm Can anyone clear this up??????????
