HMS Chanticleer was a modified Black Swan-class sloop of the Royal Navy, constructed by William Denny and Brothers in Dumbarton. The vessel was laid down on 6 June 1941, launched on 24 September 1942, and commissioned on 29 March 1943, bearing the pennant number U05. As a Black Swan-class sloop, she featured the typical design characteristics of this class, optimized for anti-submarine warfare and convoy escort duties during World War II. Following her commissioning, HMS Chanticleer underwent trials and operational readiness at Tobermory before being assigned to the 7th Escort Group based at Greenock. Her initial missions involved convoy escort in the Atlantic, notably participating in missions to safeguard ships such as a floating dock en route from Oban to Malta via Gibraltar, and escorting the KMF18 convoy between Gibraltar and the United Kingdom. In July 1943, she supported the passage of the KMF19 convoy through Beach Head, Sicily, contributing to the Allied invasion during Operation Husky. On 15 November 1943, HMS Chanticleer was engaged in convoy defense against U-boat attacks. During this engagement, she was struck by an acoustic torpedo (T5-GNAT) fired from U-515, approximately 400 kilometers east-northeast of San Miguel in the Azores. The attack resulted in the loss of 29 crew members. Severely damaged, she was towed to Horta in the Azores by HMS Salveda and declared a total loss. Subsequently, the ship was repurposed as a base ship for Royal Navy personnel in Horta, renamed Hesperides, and later changed to Lusitania II on 31 December 1943. Throughout the remainder of the European conflict, HMS Chanticleer (as Lusitania II) served as a stationary base ship until her deactivation and eventual sale for dismantling in Lisbon in 1946. Her service highlights the perilous nature of convoy escort duties and her transformation from a warship to a support vessel underscores her contribution to wartime logistics and naval operations.
