On the Mexican border, the U.S. Army forces the surrender of Matamoros to Juarez-backed troops.

Infighting between the forces of the victorious Mexican Republicans added to the chaos along the Texas/Mexico border. The local Mexican commander, named Canares, holding the town of Matamoros against fellow Mexicans loyal to Benito Juarez, had appealed four days before to the U.S. Army head across the river in Brownsville to send help "to restore order" in the town.  General John Sedgwick unwisely sent fifty men into the middle of the siege.  He lost patience with the situation after only a few days and on this day forced the surrender of the town to the Juarez forces. General Sheridan reassigned Sedgwick soon after. (By John Osborne)
