The Battle of Belchite on 18 June 1809 saw a Franco-Polish corps led by Louis Gabriel Suchet fight a small Spanish army under Joaquín Blake y Joyes. Suchet's force won the battle when a lucky hit detonated a large part of the Spanish ammunition supply. The ensuing blast provoked Blake's soldiers into a panicky flight from the battlefield. The action was fought during the Peninsular War, part of the Napoleonic Wars. Belchite is located southeast of Zaragoza.
