The USCGC Mendota was a Lake-class cutter constructed for the United States Coast Guard, launched on June 20, 1928, and commissioned on March 23, 1929. She was a sizable vessel designed for a variety of maritime duties, with a homeport in Norfolk, Virginia. During her service with the Coast Guard, Mendota played an active role in maritime rescue and aid operations. Notably, in March 1932, she assisted the oil tanker Dixie Arrow after it sustained damage during a storm. Later, on December 22, 1939, Mendota responded to the grounding of the Greek steamship Aliakmon north of Wash Woods, Virginia. During this incident, a hawser securing the vessel parted, but Mendota arrived and succeeded in floating the grounded ship, valued at approximately $200,000. In 1941, as part of the Lend-Lease Act, Mendota was transferred to the Royal Navy, where she was renamed HMS Culver (Y87). She was commissioned into the Royal Navy on April 30, 1941. Her service included rescuing personnel from sunk vessels, such as the Dutch merchant ship Bennekom, which had been torpedoed by U-96. Tragically, HMS Culver’s wartime service ended on January 31, 1942, while escorting the convoy SL 98. She was attacked and sunk by the German submarine U-105 after being struck twice—once on the port side in the forward boiler room and once near the magazine in the aft. The attack caused the vessel to break in half and sink in less than a minute, resulting in the death of her commander, seven officers, and 119 ratings. Only a handful of crew members survived, with one officer and 12 ratings rescued by HMS Londonderry. The vessel’s service history underscores her contributions to maritime safety and wartime escort duties during her active years.
