Patrol description
U-1228 left for a patrol off the Canadian coast, but the outbound boat was ordered to help the disabled U-867. Before they could make contact, U-1228 was bombed and its damaged Schnorchel resulted in a carbon monoxide poisoning of the crew, forcing the boat to abort its patrol.

Attacks on U-1228 during this patrol

18 Sep 1944
22.53 hrs, Norwegian Sea: a British B-24 Liberator (RAF Sqdn 224/R, pilot FO P.M. Hill) dropped six depth charges in a Leigh-Light attack. Most overshot, but one fell close, causing only minor damage, but with serious consequences. On diving, damage to the schnorchel caused carbon monoxide poisoning of the crew. One man died and the boat was forced to return to base. [Matrosenobergefreiter Matthias Mittler] (Sources: BdU KTB/Norman Franks)
