Battle of Santa Cruz de Tenerife: Battle between Spanish and British naval forces during the French Revolutionary Wars. During the Battle, Rear-Admiral Nelson is wounded in the arm and the arm had to be partially amputated.

The Battle of Santa Cruz de Tenerife was an amphibious assault by the Royal Navy on the Spanish port city of Santa Cruz de Tenerife in the Canary Islands. Launched by Rear-Admiral Horatio Nelson on 22 July 1797, the assault was defeated, and on 25 July the remains of the landing party withdrew under a truce, having lost several hundred men. Nelson himself had been wounded in the arm, which was subsequently partially amputated: a stigma that he carried to his grave as a constant reminder of his failure.
