HMS Arbutus (K86)

HMS Arbutus was a of the Royal Navy, which was active during the Second World War. She was a successful escort vessel, and took part in the destruction of two U-boats during the Battle of the Atlantic. Arbutus was torpedoed by a U-boat and sunk in the North Atlantic in February 1942 while aiding a convoy that was under attack.

Construction

Arbutus was placed on order in July 1939, one of the first 26 "Flowers" of the pre-war building programme. She was laid down at the Blyth Shipbuilding Company, at Blyth, Northumberland, on 30 November 1939. She was launched on 5 June 1940 and completed 12 October 1940. She commissioned on the same day.

World War II service

After trials and working up, Arbutus joined Western Approaches Command and was assigned to the 6th Escort Group, led by J. M. Rowland in for trade protection. In this role she was engaged in all the duties performed by escort ships; protecting convoys, searching for and attacking U-boats, and rescuing survivors. Over the next 14 months Arbutus escorted 26 convoys on the Atlantic routes, helping to bring over 750 ships to safety, though a number were lost in various incidents. She was involved in two convoy battles, and helped destroy two U-boats.

In March 1941, Arbutus, with the 6th EG, escorted Convoy OB 293 when it came under attack by a force of U-boats. The escort group mounted a vigorous and aggressive defence, resulting in the destruction of two U-boats and damage to a third, for the loss of two ships sunk and three damaged. During the two-night action, on 7 March 1941, Arbutus and found and attacked Template:GS; she was depth-charged and brought to the surface, where she was abandoned and sank.

In April 1941 the 6th EG went to the aid of Convoy SC 26 which was under attack. On 5 April Arbutus, with Wolverine and , found and attacked Template:GS, which was brought to the surface and abandoned. As she surfaced Arbutus was closing to ram her; when he saw she was being abandoned ArbutusTemplate:' commander, Lt. A. L. W. Warren, changed plans and attempted to capture the submarine before it sank. U-76 was boarded by several members of the crew, and efforts were made to secure and search the boat while Arbutus made fast to the U-boat with hawsers. U-76 was sinking too fast, and the attempt failed. This was the first such instance of a U-boat boarding in World War II; the exploit was repeated the following month when U-110 was captured by ships of the 3rd Escort Group.

Fate

On 5 February 1942 Arbutus was escorting Convoy ON 63 when it was detected by Template:GS. The U-boat sent a sighting report and commenced shadowing, but the transmission was DFed and escorts and Arbutus ran down the bearing to attack. The U-boat commander, K/L H. Zimmerman torpedoed Arbutus as she approached. The corvette broke in half and sank, with the loss of half her crew, 43 men, including her commander. U-136 was depth-charged by Chelsea, damaged and forced to abandon her pursuit, saving ON 63 from further harm.
