HMS Grindall (K477)

HMS Grindall (K477) was a British Captain-class frigate of the Royal Navy in commission during World War II. Originally constructed as the United States Navy Evarts-class destroyer escort USS Sanders (DE-273), she served in the Royal Navy from 1943 to 1945 and then in the U.S. Navy as USS Grindall (DE-273) from August to October 1945.

Construction and transfer
The ship was ordered on 25 January 1942 as the U.S. Navy destroyer escort DE-273 and named USS Sanders, the first ship of the name, on 23 February 1943. She was laid down by the Boston Navy Yard in Boston, Massachusetts, on 23 April 1943 and launched on 4 June 1943, sponsored by Mrs. Eugene Thomas Sanders. The United States transferred the ship to the United Kingdom under Lend-Lease on 23 September 1943.

Royal Navy, 1943-1945
The ship was commissioned into service in the Royal Navy as HMS Grindall (K477) under the command of Lieutenant Commander William Cole, RD, RNR, on 23 September 1943 simultaneously with her transfer. She served on patrol and escort duty. On 15 April 1945, she joined the British frigate HMS Keats (K482) in a depth-charge attack that sank the German submarine U-285 in the North Atlantic Ocean southwest of Ireland at position 50.21667°N, -12.8°W.

The Royal Navy returned Grindall to the U.S. Navy on 20 August 1945 at Chatham Dockyard in England.
