Ship history
She sailed from Oban on 15 August 1941, captained by F.E. Christian, and joined Convoy OG-71 (Outward Gibraltar).

On Tuesday, 19 August 1941, she joined the search for survivors from the merchantman Alva which had been sunk by GS U-559, and spent approximately an hour searching and picked up several survivors before putting on speed to catch up with the convoy. On returning to the convoy Captain F.E. Christian spotted starshells going up, on arrival he spotted a number of red lights in the water which he took to be the red lights attached to merchantmen's lifejackets (at this time Royal Navy lifejackets didn't). These were survivors from the merchantman Aguila, and after a long search Empire Oak picked up six crew members.

On Friday, 22 August 1941, during the night Captain Christian was standing on the starboard wing of the bridge when Empire Oak was struck by a torpedo fired from GS U-564 on the starboard side of the engine room. She sank within seconds with the captain been washed off the bridge. The destroyer HMS Boreas (H77) then launched a depth charge attack on U-564, the shock waves of which caused distress and injuries to the survivors in the water. Captain Christian was in the water for over two hours with his chief officer plus the chief officer from Aguila before the corvette HMS Campanula found them, unfortunately during the rescue the chief officer from the Aguila became separated and was lost.

Empire Oak lost 14 out of her 20 crew, she was also carrying 6 survivors from Aguila and 11 from Alva, nine of these were lost including all from Aguila.
