They are among our most revered icons of the Texas Revolution. These two cannons, made in Cincinnati especially for use in the struggle for independence from Mexico, served admirably as Sam Houston's only artillery in the Battle of San Jacinto. For over a century, Texas history advocates have heatedly debated the details of these cannons. Were they iron or brass? Were they 4-pounders or 6-pounders? And what happened to them? Were they buried at Harrisburg? Extensive archival research in 2014 and 2015 has revealed information that indicates the likely answers to these questions. They were iron 6-pouders, and they were last recorded in Brownsville at the end of the Civil War. They were not buried, and probably were sent back east by the occupying Union Army to be melted as scrap metal and recycled.
