The Battle of Alegre was a naval battle of the Paraguayan War fought on July 11, 1867 near the city of Corumbá, on the São Lourenço River, present-day Mato Grosso do Sul, between Brazilians and Paraguayans. During the supply of meat, "carnage", for the troops that were there, coming from the resumption of Corumbá, a small squad of Paraguayan vapors had gone up the river in pursuit of the Brazilians, after the first ones had been defeated. The Paraguayan attack was of initial surprise, but they were defeated by the men of Lieutenant Colonel Antônio João da Costa. The loss and reconquest of the Brazilian steam Jauru stood out.
