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.

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.
