This is a 3' x 5' Super-polyester flag, with a canvas header and brass grommets, with 4 rows of sewing on the fly side and is known as the Texas Navy Flag.
In November of 1835 the General Council of Texas commissioned the Republic of Texas Navy. The first ships in the Texas Navy were the Independence, Brutus, Liberty and Invincible.
The flag of the Texas Navy was created by Charles Hawkins, who was later appointed as the first Commodore of the Navy. The Navy participated in a failed expedition to capture Tampico. The expedition was outfitted in New Orleans. Mexia, the leader, tricked a number of men in the city to join the expedition, telling them that they would be taken to Texas, and would become emigrants there.
They were not told the real objective was to engage in a battle to capture Tampico. The expedition was successful in capturing a fort on the beach, but the anticipated popular uprising among the Mexicans did not develop, and the small force was quickly captured. While Mexia and Hawkins managed to escape, the remainder of the men were captured and executed.
