In 1847, after the victory of the invading U.S. Army in the Battle of Padierna (also known as the Battle of Contreras), the Mexican battalions of "Independencia" and "Bravo" were attacked in the convent of Santa María de Churubusco. This confrontation is known as the Battle of Churubusco, and the Mexican army was bravely commanded by Pedro María Anaya. When General Anaya was asked by General Twiggs to surrender his ammunition after the end of the battle, he replied, "If I had any ammunition, you would not be here".
