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.

The master, 39 crewmen, two gunners and one passenger abandoned ship, and were picked up by the British merchantman Baron Dunmore.

[11] Another damaged the 7,522-ton British merchant ship Hatarana so badly that she was abandoned by her crew of 108 and was scuttled by gunfire from the corvette HMS Pentstemon.

[12] The final two torpedoes struck the 6,318-ton Dutch cargo ship Balingkar, sinking her within 15 minutes with the loss of two men from her crew of 93.

She then managed to rejoin the convoy, but flooding in her holds forced the 56 crew and 12 passengers to abandon ship early on 29 August.
