The New Orleans Greys were a Military volunteer unit of two militia companies that totaled about 120 men that had 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.
The Greys were organized in New Orleans on October 13, 1835, at the Coffee house and Arcade of Thomas Banks. Adolphus Sterne, a Nacogdoches businessman, favored the Texas Revolution and with approval from the Texas provisional government, financed the operation.
Unlike the majority of the Texian volunteers, the Greys looked like soldiers, with uniforms, well-maintained rifles, US-pattern muskets, adequate ammunition, and some semblance of discipline. One unit of 54 Greys under Captain Thomas H. Breece and a second composed of 68 men under Captain Robert C. Morris, as well as several companies of Texians who had arrived recently, were eager to face the Mexican Army directly.
The Greys had brought an extra special piece of equipment along with them; a 18-pounder cannon. The 18-pounder had arrived at Velasco with the New Orleans Greys aboard the schooner Columbus. It had been left behind when the Greys realized that they had forgotten to bring any cannonballs for their oversized artillery. A special convoy was sent by Philip Dimmitt, commander of Fort LaBahia to retrieve the cannon. A party of 20 men were tasked with the mission to haul the 18-pounder cannon from Dimmitt's Landing to San Antonio, to use during the siege of Bexar. They were soon joined by others, including twenty members of the Greys, until the group totaled 75 men. They struggled with the giant cannon for about 200 miles, pushing and pulling, until they finally rolled in to San Antonio. They arrived two days after the battle, when General Cos had already surrendered. But all their work was not in vain; the cannon would earn a special place in the Alamo compound when it was used in the Battle of the Alamo
