Trivia Answer:
On July 25, 1845 a sidewheel steamer, the USS Alabama, anchored off Aransas Pass. Lt. Chandler of the Third Infantry waded ashore and planted Old Glory in a sand dune on San Jose island.
The island was used as a temporary camp for General Zachary Taylor's Army of Occupation before moving to the staging area in Corpus Christi in preparation for the war with Mexico that everyone knew was coming. Among the soldiers encamped on San Jose was a young West Pointer who would later make a name for himself - Ulysses S. Grant.
