The New Orleans Greys, the Greys named for the color of their uniforms, were a Military volunteer unit of two militia companies formed in the city of that name for service in the Texas War of Independence. Their name came from the grey military fatigues they wore. Unlike the majority of the Texian volunteers, the Greys looked like soldiers, with uniforms, well-maintained rifles, adequate ammunition, and some semblance of discipline. The Greys, as well several companies of Texians who had arrived recently, were eager to face the Mexican Army directly.[1]. Greys fought and died at the Battle of the Alamo, Goliad Campaign, and seven Greys served at the Battle of San Jacinto.[2]
