It was notable for seeing the loss to the Kriegsmarine (KM) of U-47, with her commander KL Günther Prien, the person responsible for the sinking of HMS Royal Oak two years previously.

OB 293 was a west-bound convoy of 37 ships, either in ballast or carrying trade goods, and sailed from Liverpool on 2 March 1941 bound for ports in North America.

After sending a sighting report he set to shadowing the convoy, being joined throughout the day by three other boats.

She torpedoed and sank the tanker Athelbeach, already damaged by U-47, and the whale factory ship Terje Viken.

The destroyer sent down a pattern of depth charges and was rewarded with an underwater explosion, marked by an orange glow, and flames that broke the surface.

However, after reviewing the available records modern historians regard this attack as being directed against UA, which was badly damaged, but survived to reach port.
