NotesApproximate losses in the Battle of the Atlantic reached about 3,500 merchant ships, 175 warships, and 783 German submarines and 17 Italian submarines. Submarine fighting also occurred beyond the boundaries of that named campaign. These totals place U-boat losses inside the much larger material and human cost of convoy warfare. They should be read as broad comparative figures rather than a complete accounting of every submarine operation.
