The Texas schooner Invincible was one of the four schooners of the Revolutionary Texas Navy (1836-1837). She began her service in January 1836 and immediately began attacking ships supplying the Mexican army in Texas, including capturing the United States merchant vessel Pocket and later the British ship Eliza Russell. Both of these actions caused diplomatic incidents between the Republic of Texas and the United States and the United Kingdom.

The Texas schooner Liberty was one of the four schooners of the First Texas Navy (1836–1838). She served in the Texas Navy for only about 6 months, capturing the Mexican brig Pelicano loaded with weapons for their army in Texas. Later that year, she sailed to New Orleans accompanying the wounded Sam Houston, where she was repaired. Texas was unable to pay for the repairs and the ship was sold in June, 1836, to pay for the cost of the repairs. This left the Texas Navy with only three ships.
