The battle of Matamoros[1] was a naval engagement during the Texas Revolution on April 3, 1836, between the brig Montezuma of the Mexican Navy and the schooner Invincible of the Texas Navy. The Mexican ship was outmaneuvered and repeatedly hit before running aground and being abandoned. The Port of Matamoros, also known as Los Brazos de Santiago, was the Mexican army's primary resupply base for the operations of General Santa Anna, who was finally defeated on April 21, 1836, outside Houston at the battle of San Jacinto.
