An attempted revolution against the rule of President Chacon broke out in January 1929 in western Guatemala. It failed, and the revolutionaries were dispersed, but they remained in control of certain towns. In February, in the course of their advance to regain control of the rebel towns, the government forces improvised an armoured wagon. It consisted of a field gun mounted on a platform wagon, protected by sleepers and sandbags.
