This brilliant strategist and courageous admiral played a crucial role in defending Spanish interests during the 18th century, marking a turning point in the naval history of his time. Below, we will explore who this hero was, his greatest achievements, and how his actions changed the course of Spain’s maritime history.
Who was Blas de Lezo?
Blas de Lezo y Olavarrieta was born on February 3, 1689, in Pasajes, Gipuzkoa, in the Basque Country. From a very young age, he showed a calling for the sea that led him to enlist in the Spanish Navy at the age of 12. His training and fighting spirit quickly made him a promising figure within the navy.
He suffered severe injuries throughout his career, earning him the nickname “Mediohombre.” He lost a leg at the Battle of Vélez-Málaga, an eye in another engagement, and an arm due to a cannon shot. However, these physical disabilities did not limit his strategic ability or his bravery in battle.
This figure was not only known for his bravery, but also for his ability to plan and carry out complex naval operations. These qualities placed him in command of important missions defending Spanish interests against rival powers such as England and France.
The great achievements of Blas de Lezo
During the War of the Spanish Succession, he took part in the defense of Toulon against Anglo-Dutch forces. Although he was seriously wounded in this battle, his performance was key in preventing the capture of this strategic port.
His role in the defense of the Caribbean
He played a prominent role in Spanish Navy operations in the Caribbean. His knowledge of sea routes and his ability to anticipate enemy movements made him a scourge to the privateers and pirates who threatened the Spanish colonies.
Blas de Lezo protected the commercial convoys connecting Spain with the Americas, ensuring the safety of shipments of gold, silver, and other goods essential to the empire’s economy.

In 1741, he led the defense of Cartagena de Indias against one of the largest fleets in history. England, seeking to weaken Spanish control in the Americas, deployed more than 180 ships and 27,000 men under the command of Admiral Edward Vernon.
Despite the overwhelming numerical and material superiority of the English, he used his ingenuity to fortify the city and take advantage of the terrain. The combination of trenches, coastal batteries, and surprise attacks proved devastating for the British.
His victory at Cartagena de Indias was one of the most remarkable in Spanish naval history. The English fleet suffered heavy losses and was forced to retreat in humiliation, securing Spanish hegemony in the Caribbean for decades.
