Blücher was a wolfpack of German U-boats that operated during the World War II Battle of the Atlantic from 14 to 28 August 1942. They attacked the Freetown, Sierra Leone to Liverpool convoys SL-118 and SL-119, and sank six ships for a total of 41,984 gross register tons (GRT), and damaged one (10,552 GRT). The group was named after Gebhard Leberecht von Blücher (1742–1819), a Prussian Generalfeldmarschall in the Napoleonic Wars.[1]
