When the Texas Revolution broke out in 1835, Texas ponied up for a navy of its own after previously relying on privateers. The revolutionary government bought four schoooners: the Independence, the Brutus, the Liberty, and the Invincible. The mission of this, the First Texas Navy, was to defend the Texas coastline while punching through the Mexican blockade, and to inflict maximum damage on the Mexican navy. (The United States Navy seemed to find all of this a bit annoying, and had minor incidents with the two warring navies.) Though the Republic of Texas won independence after Sam Houston crushed Santa Anna at San Jacinto, cannons continued to thunder in the Gulf of Mexico well into the following year. Ultimately, the Texas fleet was lost.
The second Texas Navy set sail in 1839. Its first steamship-of-war was the Zavala, a two-hundred-foot passenger schooner purchased for $120,000 and refitted for maritime operations. While returning to Galveston following a campaign to help part of the Yucatan Peninsula rebel against Santa Ana, the Zavala was badly damaged in a storm. It made it back to port, but was never restored, and was eventually scuttled.
In 1996, the National Underwater and Marine Agency (which was once a fictional government organization featured in Clive Cussler’s novels, and later founded by Cussler as a real, non-profit organization) announced that it had discovered the Zavala at Bean’s Wharf, in Galveston. It was beneath a parking lot used by workers at a nearby grain elevator. There it remains, marked as a historic site by the Texas State Antiquities Commission.
