. . "Seewolf was formed in March 1945 in an effort to re-establish the U-boat offensive in American waters; it was the last wolfpack of the Atlantic campaign. 7 of the 9 boats that sailed to Americas were in Seewolf; another 2 sailed independently. Coincidentally, Allied Intelligence formed the view that the Germans were planning to mount a missile attack on the United States, using V-1 or V-2 missiles adapted for launch at sea by submarines. This led to a vigorous response by the United States Navy, code-named Operation Teardrop, to find and destroy the Seewolf boats. This was successful; Of the 5 boats in American waters by April ( 2 boats had returned to base for repairs, and were still in transit at the end of April) 4 boats were sunk during the month: Seewolf boats had one success; U-546 sank USS Frederick C. Davis, shortly before she herself was sunk. The fifth boat U-881 was detected and destroyed on 6 May 1945, the last boat in American waters to be destroyed. The 2 boats in transit when Germany surrendered were given up to the USN on 8 May 1945."@en . . "Seven submarines"@en . "Wolf pack Seewolf"@en . "Wolf pack Seewolf"@en . "--05-06"^^ .
