Battle of Acayuazá

The Battle of Acayuazá was fought on July 18, 1868, on the outskirts of Reduto-Corá between the allied troops of the Triple Alliance and the Paraguayan army. Despite being outnumbered, the Paraguayan troops prevailed over the allies.

The battle
On the morning of July 18 the allied troops advanced to the front in two parallel columns, with the obvious purpose of taking over the Paraguayan bunker at Reduto-Corá. The allied force consisted of the 3rd Argentine Riojano Battalion and two Brazilian battalions, led by Colonel Miguel Martínez de Hoz.

The Argentine battalion marched ahead. The Paraguayans attacked them, then retreated and lured the Argentines to the stronghold, as planned.

The Argentine troops pushed forward, reaching an area where the Paraguayans scattered. This left the allies within strike range of the Reduto-Corá artillery, which suddenly erupts in a volley of gunfire. It was too late for an orderly withdrawal; the Brazilians were routed and fled, but the Argentines were surrounded by the regrouping Paraguayan forces. Argentine Colonel Miguel Martínez de Hoz was killed in combat, along with 400 Argentines soldiers.
