Brazilian victory The Battle of Paso de Mercedes was fought on 11 August 1865 during the Paraguayan invasion of the Argentine province of Corrientes.

The battle took place at Bella Vista along the Paraná River, west of Mercedes.

Following the Battle of Riachuelo, José María Bruguez, Paraguayan commander, moved his men and Major Aquino's batteries to Punta Mercedes, about 15 miles north of Stonehouse ( Corrientes), to kilometer 1157 of the Paraná River.

He chose this position on 15 meter cliffs, as it afforded the guns a good angle on the passing fleet, from which he fired canister and grapeshot.
