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.
Background
Suchet took command of the III Corps and immediately moved to oust the army of Captain General Blake from Aragon. The resulting Battle of Alcañiz on 23 May was a victory for the Spanish as they repulsed a Franco-Polish frontal attack. This victory brought Blake's army 25,000 volunteers, many of whom could not be provided with weapons. Blake advanced down the Huerva River with two divisions on the left bank and one division under General Juan Carlos de Aréizaga on the right bank. A more circumspect Suchet initially fought on the defensive in the Battle of María on 15 June. The French general sent General of DivisionAnne-Gilbert Laval with a 2,000-man brigade to watch Aréizaga while retaining the rest of his small corps to face Blake. After fending off Blake's attacks for several hours, Suchet went over to the attack when some French reinforcements arrived. He overwhelmed the Spanish right flank and compelled Blake to order a withdrawal. The next day, Suchet advanced against the combined forces of Blake and Aréizaga. Blake declined to fight and instead fell back. Discouraged by defeat, 3,000 of Blake's new recruits deserted.
Battle
After joining with Aréizaga's division, Blake was only able to muster 11,000 infantry, 870 cavalry, and nine guns. He drew up this force on some hills in front of the town of Belchite. After Suchet ordered Laval to join him, he massed 12,000 infantry, 1,000 cavalry, and 12 artillery pieces for the battle. The French general paid no attention to the Spanish center and instead sent his two divisions to attack the enemy flanks. General of Division Louis François Félix Musnier assaulted the Spanish left flank and began forcing it back into the town. General of BrigadePierre-Joseph Habert sent his soldiers against the opposite flank. Just as Habert's attack got rolling, a French shell blew up an artillery caisson in the Spanish right rear. The fire spread to some ammunition wagons and soon there was a titanic explosion as Blake's gunpowder supplies detonated. With this, the Spanish soldiers panicked, some throwing down their muskets in order to flee faster. The French swept forward, killing, wounding, or capturing 2,000 Spaniards. They seized all nine of Blake's cannons plus one color and a quantity of food and equipment. Suchet reported losses of 200 killed and wounded. Leaving Musnier's division to observe Blake's survivors, Suchet marched back to Zaragoza.
