The Reina Mercedes was an Alfonso XII-class unprotected cruiser constructed for the Spanish Navy, launched on 9 September 1887 at the naval shipyard in Cartagena. Characterized by her two funnels, she was designed for high-speed colonial patrols with moderate armament, featuring main guns built by Hontoria that were sponson-mounted. Her armament included five fixed torpedo tubes—two forward, one on each beam, and one aft—reflecting her intended role in colonial waters. Although her design emphasized speed and operational reach, chronic machinery problems rendered her relatively slow, limiting her effectiveness. The vessel’s hull lacked armor but incorporated 12 watertight compartments built in a French-style cellular system, intended to improve her resistance to flooding. Her early service involved operations within Spanish waters as part of the Instructional Squadron, before being transferred in 1893 to the Caribbean, where she served as the flagship of Spanish naval forces operating near Cuba. Notably, in 1897, Reina Mercedes fired two shots at the American passenger liner SS Valencia off Guantánamo Bay, an incident later understood as a warning rather than an act of hostility. During the Spanish–American War, Reina Mercedes was stationed at Santiago de Cuba, awaiting repairs amid her machinery troubles, with most of her boilers out of service. She played a role during the blockade of Cervera’s squadron, engaging U.S. forces in June 1898, and was hit multiple times, suffering fires and the death of her second-in-command. As the Spanish fleet prepared to attempt an escape from Santiago de Cuba in July 1898, Reina Mercedes lacked the speed to follow due to her mechanical issues. Her crew scuttled her in the harbor entrance on 4 July 1898 to prevent capture, after most of her guns had been removed for land defense. The U.S. Navy salvaged her in early 1899, and she was subsequently commissioned as the USS Reina Mercedes, serving as a disarmed receiving ship. Her service history underscores her role in the Spanish–American War and her subsequent reuse by the U.S. Navy, marking her as a vessel of both tactical significance and technological limitations.
