Blas de Lezo, Spanish admiral (d. 1741)
Admiral Blas de Lezo y Olavarrieta (3 February 1689 – 7 September 1741) was a Spanish navy officer best remembered for the Battle of Cartagena de Indias (1741) in the Viceroyalty of New Granada, where Spanish imperial forces under his command decisively defeated a large British invasion fleet under Admiral Edward Vernon.

Throughout his naval career, Lezo sustained many severe wounds; he lost his left eye, left hand, complete mobility of the right arm, and had his left leg amputated in situ after being hit by the projectile of a cannon. He perceived his wounds and physical limitations as medals, refusing to wear an eye patch to hide his blind eye. Wearing his past battles history on his flesh won the respect of his peers and soldiers.Lezo's defense of Cartagena de Indias against a vastly larger British fleet consolidated his legacy as one of the most heroic figures in the history of Spain. He is often recognized as one of the greatest strategists in naval history.
