SS Wanstead at Newlyn

21st April 1943 - SS Wanstead sunk by U-413 at 55.46N, 45.14W. She was hit earlier in the night by U-415 and the crew abandoned her fearing for their lives (understandably); I will try and dicover more, since I thought HMS Poppy was involved.

The 5,486 ton steam freighter S.S. Wanstead was owned by Watts, Watts and Coy of London. She was built in 1928 by the Caledon Shipbuilding and Engineering Coy of Dundee and was on a voyage from Tyne / Oban for New York, in ballast, and a straggler from Convoy ONS3, when she was torpedoed and badly damaged by the German Type VIIC submarine, U-415, under the command of Oberleutnant zur See Herbert Werner. In this attack, two men were killed. The Master, Captain William B. Johnston, along with forty crewmembers and seven gunners, abandoned ship in the lifeboats. This action took place North-East of Newfoundland, in position 55 46 North, 45 14 West at 08:14 hours on the morning of 21st April 1943. The British naval vessels HMS Poppy (Corvette) and HMS Northern Gift (AWS Trawler) picked up the 48 survivors. HMS Poppy attempted to sink the still floating merchantman, unsuccessfully, and the coup de grace was delivered later that day, 13:45 hours, by the German Type VIIC submarine U-413, under the command of Kapitanleutnant zur See Gustav Poel. Meantime, the survivors were landed at St. Johns by the British naval vessels.

Further discussion reveals that this is an earlier smaller vessel than the one I have described above; for now, it appears this ship was built in 1912; she was acquired by another company in 1916 and renamed Teesburn, so that would date this picture quite well.
