The Naval Battle of Campeche took place on April 30, 1843, and May 16, 1843. The battle featured the most advanced warships of its day, including the Mexican steamer Guadalupe and the equally formidable Montezuma which engaged a squadron of vessels from the Second Republic of Yucatán and the Republic of Texas. The latter force consisted of the Texas Navy flagship sloop-of-war Austin, commanded by Commodore Edwin Ward Moore, the brig Wharton, and several schooners and five gunboats from the Republic of Yucatán, commanded by former Texas Navy Captain James D. Boylan.
