sentences:  In the Naval Battle of Campeche on 16 May 1843 the Texas Navy sloop-of-war "Austin" and brig "Wharton", supported by ships from the rebellious Mexican State of Yucatan (then the Republic of Yucatán), engaged Mexican naval vessels, including the steamships "Montezuma" and "Guadalupe".This battle is believed to be unique, marking the only occasion in which a sailing warship engaged and fought a steam-powered warship to a draw.The battle, which raged over several days, was a tactical draw, but a strategic victory for the Texan Navy, which forced the Mexicans to lift their blockade of Campeche and assured security in the meantime for the rebels in Yucatan.
