Guatemalan victory The War of 1863[1] (Spanish: Guerra de 1863) was a conflict fought between El Salvador and Guatemala from 13 February 1863 to 26 October 1863.

Barrios was overthrown on 26 October 1863 and was replaced by a conservative politician, Francisco Dueñas, ending the war.

[1][3][5] During the invasion, many Salvadorans deserted and either refused to take part in the war or joined the Guatemalans, most notably general Santiago González who served under Barrios during the Battle of Coatepeque.

[5][6] Carrera ordered a cease fire from San Salvador to submit, and after a month of being sieged, the capital fell on 26 October.

[5] Barrios fled the city and went east to San Miguel, after which, Dueñas was declared President of El Salvador.
