Galveztown Documents, 1777-1793. 29 items. Location: Misc.:G. Gilbert Antoine de St. Maxent was sent by Governor Bernardo de Gálvez in 1778 to settle Islenos (immigrants to Louisiana from the Canary Islands) at Galveztown, which was located at the junction of the Amite River and Bayou Manchac, to be a military stronghold against the British in West Florida. Galvestown soon lost its importance as a military post and began to decline from disease, floods, hurricanes, droughts, and high shipping costs. The present day community of Galvez, La., is located just west of the original Galveztown. Mss. 3990.
