HMS Lancaster was a 64-gun third-rate ship of the line of the Royal Navy, launched on 29 January 1797 at Rotherhithe. Originally constructed as the East Indiaman Pigot for the British East India Company, she was purchased by the Royal Navy while still on the stocks due to a shortage of naval vessels during the French Revolutionary Wars. In terms of specifications, as a third-rate ship of the line, Lancaster was armed with 64 guns, making her a significant combat vessel capable of engaging in fleet battles. Her design and construction from the Pigot suggest a sturdy build suitable for both merchant and combat roles, although specific dimensions are not provided in the source. Throughout her service, Lancaster participated in several notable operations. By March 1800, she was at Cape Town, and in July of the same year, she was part of a squadron under Vice-Admiral Roger Curtis, which included ships like Adamant, Rattlesnake, and Euphrosyne. This squadron was tasked with blockading Île de France and Bourbon, remaining in the area until October and sharing in the proceeds from several captures during this period. Lancaster also played a role in the 1806 British invasion of the River Plate, sailing from Simon’s Bay in August as an escort for transports, including the Pretty Lass. However, this invasion was unsuccessful. By 11 March 1815, after nearly two decades of service, Lancaster was converted into a storage hulk, marking the end of her active combat role. She remained in this capacity until she was offered for sale on 30 May 1832 at Woolwich. Subsequently, she was sold to Christall & Co., London, for breaking up, ending her maritime career. Overall, HMS Lancaster was a versatile vessel that served during a turbulent period of naval warfare, contributing to British maritime operations before her decommissioning and dismantling.
