General notes on this boat

The first US Navy ship lost in the Atlantic

On 31. October, 1941 U-552 was attacking the eastbound convoy HX-156 and at roughly 0525 hours torpedoed one of its escorts. The ship's magazine exploded and the ship sank quickly and 100 out of its crew of 144 perished. The ship was the destroyer USS Reuben James and it was the first US Navy ship lost in hostile action in WWII.

This took place roughly 6 weeks before war was declared between Germany and the United States although US Navy ships had been escorting convoys and attacking U-boats for months before that.

Men lost from U-boats

Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-552 did not suffer any casualties (we know of) until the time of her loss.
