Overview
The Battle of Piribebuy was fought on 12 August 1869 in the Paraguayan town of Piribebuy, which was then serving as a temporary capital of the Paraguayan government. The Paraguayan defenders, who were poorly armed and included children, fought the attacks of the Allied forces, led by French-born Brazilian general prince Gaston of Orleans, the Count of Eu, son-in-law of Emperor Pedro II of Brazil. The town refused two peace envoys calling for surrender, sent by the Count of Eu. At 04:00, the Brazilian batteries surrounding the town started a bombardment which lasted until 08:00, when the infantry charged. General João Manuel Mena Barreto was mortally wounded leading a cavalry charge against the Paraguayans.

Significance
Piribebuy held particular symbolic weight because the town was serving as the temporary capital of the Paraguayan government at the time of the attack. Its fall to Allied forces under the Count of Eu represented not merely a tactical gain but the overrunning of Paraguay's seat of government during the final stages of the Paraguayan War. The garrison's refusal of two surrender demands before the battle, combined with a defending force that included children and poorly armed fighters, underscored the extent to which Paraguay had been reduced in manpower and resources by this stage of the conflict. The complete destruction of the defending force — casualties matching the entire garrison strength of 1,600 — illustrated the overwhelming Allied numerical advantage of more than twelve to one.
Tactics
Allied forces under the Count of Eu surrounded the town and opened a four-hour artillery bombardment beginning at 04:00. When the bombardment lifted at 08:00, infantry charged the Paraguayan positions. Cavalry was also committed to the assault; Brazilian general João Manuel Mena Barreto was mortally wounded leading a cavalry charge against the defenders. The Paraguayan garrison, though poorly armed and including children, had earlier refused two peace envoys sent by the Count of Eu calling for surrender before the assault began.
