The Battle of Tacubaya took place on 11 April 1859 near the ancient village of Tacubaya in today's Federal District, Mexico City, Mexico, between elements of the liberal army, under General Santos Degollado and elements of the conservative army commanded by General Leonardo Marquez during the War of Reform. The victory corresponded to the preservative side, generating heavy casualties on both sides. After the battle General Miramon ordered Marquez to shoot the captured liberal chiefs and officers, including the head of the Army Medical Corps, as well as other liberal doctors. The executions came to be known as The Massacre of Tacubaya, and both this and the battle itself earned Leonardo Marquez the nickname of "Tiger of Tacubaya".
