HMS Tay was part of convoy ONS-5 escort. Her Commander, Robert Sherwood, RNR, was given (from Cdr. Gretton, in destroyer HMS Duncan) the duty of Senior Officer Escort of the convoy, on May 3rd. Three days later, the corvette HMS Snowflake found U-125 just 100 meters away, badly damaged. The submarine's crew scuttled the boat, and another corvette, HMS Sunflower, turned up. When they were about to rescue the Germans, a regretable order came from Sherwood: "Not approved to pick up survivors". So both corvettes made off, letting the entire crew of the submarine to perish in the cold waters.
