At 0440 hours, a lone destroyer was sighted on an easterly course at 18-20 knots. Ten minutes later, two torpedoes were fired at a range of 1,000 metres but missed.

One torpedo track was sighted by the destroyer and she tried to locate the submarine but could not obtain a contact.

The submarine seen was probably the latter.

At 1330 hours, an aircraft, identified as a Saro London bomber, came from the sun and attacked Velella as she was preparing to dive. The aircraft strafed the submarine and dropped six bombs which missed her by 300 to 400 metres. This was in fact Hudson 'G' (FH398) of 233 Squadron piloted by Flying Officer W.E. Willits. It had sighted the submarine at a distance of 20 miles and dived from 3,500 feet. Only four depth charges were dropped and estimated to miss the submarine by 70 yards.
