Siege of Querétaro

The Siege of Querétaro was the culminating battle of the French Intervention in Mexico and the Second Mexican Empire. It took place between Republican and Imperial armies from 6 March to 15 May 1867.

The Republican victory at Querétaro effectively ended the war of the Second French Intervention. Emperor Maximilian I was captured and condemned to death by a court martial on June 14; resulting in his execution by firing squad on the morning of June 19 at the Cerro de las Campanas.
