The Battle of Canchas Blancas took place in western Bolivia on November 12, 1879. According to the recently discovered diary of a Bolivian colonel, several hundred Bolivian soldiers, peasants, and indigenous people armed with machetes, clubs, and stones defeated a force of about 1,500 Chilean soldiers backed by cavalry and artillery.
The defeat halted the Chilean force's advance toward Paraguay. More than 300 were killed, but the victory is a source of pride for Bolivia. Chilean historians have said, "the battle is sort of a legend generated in the bosom of the Bolivian army."
"Our Indians and soldiers saved the fatherland," Morales said at the reenactment, lamenting the "Chilean oligarchy" that he said was holding on to a "colonial mentality" about the war and its resolution.
Bolivia signed a peace treaty with Chile in 1884. Its quest to regain access to the sea would lead it into another conflict a half-century later: the brutal Chaco War, in which Paraguay rebuffed Bolivia's efforts to reach the Atlantic via the Rio de la Plata river system.
Bolivia filed suit with the International Court of Justice in 2013, asking it to compel Chile to negotiate "in good faith." "Bolivia is not asking to be granted a wish," Morales said on Twitter this month. "Bolivia demands that its sovereign right to the sea be returned."
