Besides their success in the early years of the war, the U-Boats paid a terrible price for it. About 80% of all U-Boats were destroyed, 28.000 of the 40.000 U-boat personal were killed during the war, 8.000 were captured. Since detailed information for all U-Boat classes and single ships would be too voluminous for this web page, only a short overview about the single U-Boat types is given here.
