First Cortina War (13 jul 1859 año – 17 mar 1860 año)

Descripción:

A conflict in Brownsville, TX between Cortinistas led by Mexican rancher and military leader (not associated with and considered an outlaw by the Mexican government) Juan N. Cortina and several groups in the US, including the US military, Texas Rangers, and a local resistance group called the Brownsville Tigers. It started when Cortina shot Brownsville marshal Robert Shears. By late September, Cortina had captured the town of Brownsville. The Brownsville Tigers allied with a group of Texas Rangers and some US troops and defeat Cortina by March 1860. Cortina would later cause further trouble in the Second Cortina War in 1861, where Cortina would lose an additional 18 men in an unsuccessful attack on Zapata County, TX against Confederate forces.

Casualties:
31 Americans killed or wounded
198 Cortinistas (+18 from the Second Cortina War)
