What happened to Justo Rufino Barrios at the Battle of Chalchuapa?

At the Battle of Chalchuapa in 1885, Justo Rufino Barrios, the president of Guatemala, was killed while leading an invasion of neighboring El Salvador.12

Barrios, a staunch advocate for Central American unity, had attempted to restore the five-nation federation that had collapsed in 1838. When his efforts to achieve this through political persuasion failed, he sought to force the unification of the region through military intervention. His death during the battle effectively ended his movement to forcibly unify Central America.12
