Heinrich Zimmermann joined the Reichsmarine in 1932. From Aug 1939 to May 1940 he served as an acting Commander of the 7th Minesweeping Flotilla while commanding his own minesweeper. He then joined the 3rd Minesweeping Flotilla from May 1940 to March 1941 (Busch & Röll, 1999).
From March to Aug 1941 he went through U-boat training, U-boat Commander training, and finally U-boat construction familiarization (Baubelehrung) for his own U-boat command (Busch & Röll, 1999).
On his first patrol around the British Isles he sank four ships (almost 13,000 tons) from four different convoys before arriving at his new base at St. Nazaire, France on 1 March 1942. These included the British corvette HMS Arbutus (K 86) on 5 Feb, and on 11 Feb the Canadian corvette HMCS Spikenard (K 198) (Rohwer, 1998).
His second patrol was also successful. This time he operated off the US east coast and sank three ships (12,707 tons) and damaged a large ship of 8,955 tons (Rohwer, 1998). He arrived back to France on 20 May 1942 after 58 days at sea (Busch & Röll, 1997).
On 29 June 1942 Zimmermann left base in U-136 for the last time (Busch & Röll, 1997). 13 days later his boat was sunk with all hands (45 men) in the Atlantic west of Madeira, Portugal by depth charges from the Free French destroyer Léopard, the British frigate HMS Spey and the British sloop HMS Pelican (Niestlé, 1998).
