Notes on event

At 01.22 hours on 12 June 1941, U-553 fired one torpedo at an unescorted freighter about 370 miles north-northeast of the Azores and observed how the ship sank within 90 seconds after being hit underneath the bridge. The U-boat had spotted the ship about five hours earlier and missed with a stern torpedo at 01.05 hours. The target must have been the Susan Mærsk (Master Kaj Bjørn Thomsen) which was reported missing after being detached from convoy OG-64. The master, 22 crew members and one gunner were lost.
