Ships hit by U-boats off the US East Coast (and Gulf)

The losses off the US East Coast were overwhelmingly in 1942 during Operation Drumbeat and its successor operations, but the U-boats visited the area throughout the war.

This map, currently, includes ships lost in the Gulf of Mexico which has its own map. As it is now this map shows the entire US coastline and losses off it.

311 ships hit in the area, 255 ships sunk (1,425,996 GRT) and 56 ships damaged (397,444 GRT).
