Battle of Boquerón

Source · Wikipedia

Significance

The Battle of Boquerón was the first major engagement of the Chaco War, fought over the Bolivian-occupied fortín of Boquerón. Bolivian forces had seized the outpost in late July 1932 on orders from President Daniel Salamanca, a move that escalated a border dispute into full-scale war between Bolivia and Paraguay. The battle thus marked the point at which localized frontier tension became open conflict between the two nations.
