The Battle of Cañada Strongest was a major military action from May 10 to May 25, 1934 during the Chaco War, in which Paraguayan forces were ambushed and defeated by three Bolivian divisions. The engagement is considered the greatest victory of the Bolivian army during the war. The battle actually took place some 60 km southwest of Cañada Strongest, near a dried riverbed called Cañada Esperanza. The battle began as a Paraguayan attempt to outflank and eventually conquer Fort Ballivian, a large stronghold that was the keystone of Bolivian defenses along the border with Argentina. Paraguayan forces began to open a new trail in the dry subtropical forests of the Chaco but were discovered by Bolivian aerial reconnaissance. The Paraguayan troops, unaware of having been discovered, were encircled by Bolivian forces who had sneaked up on the path and were waiting for a substantial number of Paraguayan troops to enter the pathway before they ambushed them.
