Blas de Lezo, Spanish admiral (d. 1741)

Admiral Blas de Lezo y Olavarrieta, born on February 3, 1689, in Pasajes, Gipuzkoa, Spain, and passing on September 7, 1741, in Cartagena de Indias, Viceroyalty of New Granada (modern-day Colombia), stands as one of the most remarkable figures in Spanish naval history. This formidable Spanish navy officer is predominantly celebrated for his pivotal role in the defense of Cartagena de Indias in 1741, a confrontation that saw Spanish imperial forces under his astute command deliver a decisive defeat to a significantly larger British invasion fleet led by Admiral Edward Vernon.

Lezo's distinguished naval career was marked not only by strategic brilliance but also by extraordinary personal sacrifice. From a young age, he exemplified unwavering resolve, entering military service as a midshipman at just 12 years old. Throughout his extensive service to the Spanish Crown, Lezo endured an astonishing series of severe combat wounds that would profoundly alter his physical appearance yet never diminish his spirit or resolve. At the age of 15, while participating in the Battle of Vélez-Málaga in 1704 during the War of the Spanish Succession, he lost his left leg after being struck by a cannonball, necessitating an immediate amputation on the battlefield – a testament to the brutal realities of naval warfare in that era. Later, during the siege of Toulon in 1707, he lost his left eye, and in 1713, during a campaign against Barcelona, he suffered the loss of his right arm's complete mobility, effectively rendering it useless, and lost his left hand in another engagement. These grievous injuries earned him the formidable monikers of "Patapalo" (Pegleg) and "Mediohombre" (Half-man) among his peers and adversaries alike, though he himself famously regarded his wounds not as disabilities but as "medals" of honor. His refusal to conceal his blind eye with an eye patch, openly displaying the scars of his past battles, served as a powerful symbol of his courage and unwavering commitment, earning him profound respect and admiration from his subordinates and fellow officers.

The zenith of Admiral Blas de Lezo's career, and indeed one of the most iconic moments in naval history, came during the Battle of Cartagena de Indias in 1741. This epic siege occurred during the War of Jenkins' Ear, a conflict primarily between Great Britain and Spain over trade rights and territorial claims in the Americas. Cartagena de Indias, a vital Spanish port city and gateway to the riches of the Viceroyalty of New Granada, served as a crucial strategic objective for the British. Their formidable invasion force, led by Admiral Edward Vernon, comprised an estimated 186 ships, including 29 ships of the line, and carried roughly 27,000 men – a combined strength far exceeding that of any fleet assembled by the British Royal Navy up to that point. In stark contrast, Lezo commanded a significantly smaller force of merely six ships of the line, alongside a few frigates, and approximately 3,000 Spanish soldiers, supported by local colonial militia and indigenous allies. Despite the overwhelming numerical disadvantage, Lezo’s exceptional tactical genius, profound understanding of defensive fortifications, and resolute leadership transformed Cartagena’s natural defenses into an impenetrable bulwark. He meticulously prepared the city's defenses, sinking ships to block harbor entrances, constructing new batteries, and strategically deploying his limited forces. The British assault, intended to be swift and decisive, faltered under relentless Spanish resistance and the clever deployment of Lezo's defensive strategies. After weeks of intense fighting, debilitating disease within their ranks, and repeated failed attempts to breach the city’s defenses, the British fleet was compelled to withdraw, suffering catastrophic losses that included thousands of casualties and numerous ships. This resounding victory not only secured Spain's dominion over its vital Caribbean territories but also stands as one of the most crushing defeats in British naval history and a testament to Lezo's unparalleled strategic prowess.

Admiral Blas de Lezo's extraordinary defense of Cartagena de Indias against such a vastly superior British force irrevocably cemented his legacy as one of the most heroic and inspirational figures in the annals of Spain's military history. His strategic brilliance, coupled with his unyielding resilience in the face of immense physical challenges, has led to his widespread recognition as one of the greatest strategists in naval history. Even today, he is honored with statues and monuments across Spain, serving as a powerful symbol of national pride and indomitable spirit. His story continues to inspire, embodying the principles of courage, determination, and tactical genius in the face of overwhelming odds.
