As HMS Lincoln
Yarnall was one of the 50 elderly destroyers chosen to be transferred to the Royal Navy in return for the right to establish American bases on British territory in the western hemisphere. She sailed to St. John's, Newfoundland, where she was decommissioned by the United States Navy on 23 October 1940; and, that same day, the Royal Navy commissioned her as HMS Lincoln (G.42) as a Town class destroyer, Comdr. G. B. Sayer, RN, in command.
The veteran destroyer departed St. John's on 3 November and arrived in Belfast, Northern Ireland, on the 9th. Lincoln moved from there to Londonderry Port where she was assigned to the First Escort Group, Western Approaches Command. For almost a year, she met troop transport and cargo convoys in mid-ocean and escorted them into ports in the British Isles. Between September 1941 and February 1942, the destroyer was refitted at Woolwich Dockyard. Lincoln was modified for trade convoy escort service by removal of three of the original 4"/50 caliber guns and one of the triple torpedo tube mounts to reduce topside weight for additional depth charge stowage and installation of Hedgehog.
