Cause

Paraguay launched an invasion of the Brazilian Province of Mato Grosso as part of the wider Paraguayan War. A Paraguayan column of 3,500 soldiers advanced southward and reached the Military Colony of Dourados, which was defended by only a small Brazilian garrison under Lieutenant Antônio João Ribeiro.

Event

On 29 December 1864, the Paraguayan force reportedly offered the garrison terms of surrender, which Lieutenant Ribeiro refused. In the ensuing combat at the Military Colony of Dourados, Ribeiro and all fifteen of his men were killed, vastly outnumbered by the invading column.

Consequence

With the Brazilian garrison annihilated, the Paraguayans seized the Military Colony of Dourados and continued their advance into the Province of Mato Grosso. The defense became a symbol of Brazilian resistance, and the engagement marked the opening action of the Mato Grosso campaign of the Paraguayan War.
