U-1229 was ordered in October 1941 from Deutsche Werft AG Weser in Hamburg-Finkenwerder under the yard number 392. Her keel was laid down on 2 March 1943 and was launched on 22 October 1943. About three months later she was commissioned into service under the command of Korvettenkapitän Arnim Zinke (Crew 31) in the 31st U-boat Flotilla.
After completing training and work-up for deployment U-1229 was transferred to the 10th U-boat Flotilla for front-line service on 1 August 1944. The U-boat left Kiel on 13 July 1944 for the first and only war patrol operating unsuccessfully against Allied shipping in the North Atlantic and off the coast of Canada. A special mission to infiltrate an Abwehr agent into the United States failed, when U-1229 was spotted south of Newfoundland by an Radar-equipped aircraft from USS Bogue and subsequently attacked by several more aircraft over a period of two hours. Having been heavily damaged in the initial air attack, U-1229 attempted to escape under water but was forced to surface again as poisonous fumes started to develop from the damaged battery sections. While the crew was abandoning ship, the U-boat was strafed by several aircraft resulting in the death of numerous crew members, including Zinke. In total 18 crew members died while 41 survivors were picked up by a US destroyer after seven hours in the water.
