Hans-Wilhelm von Dresky joined the Kriegsmarine in 1929. He served as a Watch Officer (WO) on U-20 Feb 1936 - Sept 1937, when he took command of the small Type IIA U-4 on 30 Sept 1937.

Von Dresky left U-4 on 28 Oct 1938, and the following day took command of the larger Type VIIA boat U-33. On his first two patrols he sank ten small ships (19,261 tons) and destroyed another of 3,670 tons.

For his third patrol he was sent to the Firth of Clyde lay eight TMC mines close to the British naval base there - a highly dangerous task. When he nosed his boat into the Firth she was detected by the British minesweeper HMS Gleaner, but von Dresky mistook her for a cruiser and thought she would pass him and head for open waters. He thus dived, and after Gleaner dropped six depth charges on the boat, surprising the Germans, and causing severe damage and several leaks, the boat bottomed at only 36m (119 ft). Over the next hour, two more batches of depth charges followed, which caused further damage. Von Dresky ordered the boat to surface and then scuttle, distributing the Enigma cipher machine wheels to three of his men to throw into the sea away from the boat.

The freezing cold water temperatures meant only 17 men survived the sinking, and 25 died from the shock of immersion and hypothermia, including Kptlt. von Dresky (Blair, 1996, Sebag-Montefiore, 2000). One of the survivors had failed to dispose of his cipher wheels, and they were discovered by the British. They played a crucial part in the British breaking of the German navy Enigma codes (Sebag-Montefiore, Enigma, 2000).
