Corrientes Fall into Paraguayan Claws
April 13, 1865 — Paraguay Attacks the City of Corrientes: The War of the Triple Alliance Begins
Moored at the port of the provincial capital Corrientes were two Argentine ships, the 25 de Mayo and the Gualeguay. Both vessels were in port for repairs — unarmed, with reduced crews, and some sailors on shore leave.
On the morning of April 13, 1865, around six o’clock, five Paraguayan steamships appeared off the shores of Corrientes. Without any declaration of war, they swiftly positioned themselves and attacked the defenseless Argentine ships — an unprovoked, treacherous assault.
Outnumbered, the Argentine sailors mounted a heroic resistance, but they were soon overpowered and captured. Three hundred Paraguayan sailors seized around eighty Argentines; several who had already surrendered were immediately executed — beheaded by Guaraní fighters. The Argentine flags were struck down, thrown to the ground, while the attackers shouted praises for Marshal Solano López. Some sailors tried to escape by diving into the water but were shot and killed.
Meanwhile, 2,500 Paraguayan troops landed in the city of Corrientes, occupying the provincial capital. Other Paraguayan columns invaded the Mesopotamian provinces via various crossings, bringing the invasion force to a total of 27,000 men.
The surviving Argentine sailors would spend the rest of the war in captivity under inhumane conditions; many would die in prison. The Paraguayan occupation of Corrientes was harsh and brutal: kidnappings, rapes, destruction of Argentine property, and summary executions. Five local women — some with young children — were famously kidnapped and taken to Paraguay, later remembered as the “Cautivas correntinas”.
The legitimate governor, Manuel Lagraña, managed to escape with some soldiers into the provincial interior, seeking to gather men to repel the Paraguayan invasion. The invaders, in turn, set up a puppet government, fully subject to Asunción’s decisions.
It would take nearly a year — and bloody battles like Yatay and Pehuajó — to finally expel the invaders from Corrientes province.
This Paraguayan attack would ultimately trigger Argentina’s formal entry into the war, marking the start of the bloody War of the Triple Alliance.
