History

U-100 was a Type VIIB U-boat, commissioned 30 May, 1940. She conducted six war patrols between August, 1940, and March, 1941, accounting for twenty-five ships sunk, four damaged, and one written off as a total loss, for a total of 155,048 tons. This made her one of the top scoring U-boats of the War. She was caught on the surface by radar as she approached Convoy HX 112 on 17 March, 1941, and was rammed by the V-class destroyer HMS Vanoc. U-100 has the distinction of being the first U-boat to be located by radar. Only six of U-100's crew survived the sinking.
