Anecdotes

In 1817, San Martín accomplished one of the greatest military feats in history: he led his army across the Andes mountain range — roughly 5,000 men with cannons, horses, and mules — through passes lying at over 4,000 meters above sea level. The preparations lasted months and many animals perished from the cold, but the element of surprise allowed him to crush the Spanish in Chile.

San Martín was obsessed with secrecy and cunning: before crossing the Andes, he spread false rumors and even led some indigenous chiefs to believe he would pass through certain mountain passes, knowing the information would be relayed to the Spanish. Meanwhile, his troops took other routes.

In 1822, during the Guayaquil Conference, San Martín met the other great liberator, Simón Bolívar. The exact content of their conversation remains a mystery, but in the wake of this meeting San Martín decided to withdraw and leave the completion of independence to Bolívar, in order to avoid a civil war among the patriots.

After liberating three nations, San Martín refused power and went into voluntary exile in Europe in 1824. He died in 1850 in Boulogne-sur-Mer, France, almost forgotten, far from the America he had helped to free. His remains were not repatriated to Argentina until 1880.

San Martín suffered from chronic pain and took laudanum (an opium-based preparation) to relieve it, which took nothing away from his military rigor. He imposed iron discipline on his Army of the Andes, which he regarded as the key to the continent's freedom.
