The New Orleans Greys was a Military volunteer unit of two militia companies that totaled about 120, formed in the city of that name for service in the Texas War of Independence.

That afternoon, the entire group joined with the Gonzales relief unit waiting at the Cibolo Creek, 35 miles (56 km) from the Alamo.
