Texas’ inclusion in the American Revolution began on June 21, 1779, when Spain declared war on Great Britain. Over 10,000 head of Texas cattle were rounded up on the vast rancheros operated by the Spanish missions that spread along the San Antonio River. Presidio La Bahía at Goliad served as the gathering point from which its soldiers escorted the vaqueros trailing the cattle and several hundred horses up through Nacogdoches in East Texas to Natchitoches and on to Opelousas in Louisiana. To help finance Spain’s involvement in the war, King Carlos III asked for donations of one peso “from all men, whether free or of other status” and two pesos from Spaniards and nobles. An accounting dated January 20, 1784, lists a total of 1,659 pesos from presidios all over Texas where the cavalry had two pesos each taken from their pay. At that time two pesos represented the price of a cow.
King Carlos III commissioned Bernardo de Gálvez, the governor of Louisiana, to raise an army and lead a campaign against the British along the Mississippi River and the Gulf of Mexico. Gálvez had been in contact with Patrick Henry, Thomas Jefferson, and Charles Henry Lee who sent emissaries requesting that Gálvez secure the port of New Orleans and permit only American, Spanish, and French ships to travel the Mississippi River. The Mississippi served as the doorway through which vast amounts of arms, ammunition, and military supplies could be moved to the troops fighting in Kentucky, Illinois, and along the northwestern frontier.
The cattle grazing the mission rancheros in Texas offered the best hope for Gálvez to feed his Spanish troops and the governor of Spanish Texas eagerly answered the request. The Texas beef helped feed from 1,400 to over 7,000 as the campaigns under Gálvez moved from the defeat of the British at Manchac and Baton Rouge in Louisiana and on to a victory at Natchez, Mississippi. After a month-long siege using land and sea forces in 1780, Gálvez captured Fort Charlotte at Mobile. The final push to secure the Gulf Coast began in 1781 when Spanish troops captured Pensacola, the British capital of West Florida. The next year, a two-month siege finally overwhelmed Fort George in Pensacola, leaving the British with no bases in the Gulf of Mexico. Finally, the Spanish force under Gálvez captured the British naval base in the Bahamas. The war ended before Gálvez could initiate plans to take Jamaica. The campaigns under Gálvez kept the British from encircling the American revolutionaries from the south and kept the supply lines open from the western flank.
Gálvez helped draft the terms of the 1783 Treaty of Paris, which officially ended the American Revolutionary War and returned Florida to Spain from British control. George Washington honored Gálvez by placing him to his right in the July 4 parade, and the American Congress recognized Gálvez for his service during the revolution. Gálvez capped his career in 1785 when the Spanish crown appointed him viceroy of New Spain.
While Gálvez served as governor of Louisiana, he ordered a cartographer to survey the Gulf Coast. The mapmaker named the largest bay on the Texas coast “Bahía de Galvezton,” later becoming Galveston. Galveston County and St. Bernard Parish in Louisiana are among several places that bear his name. The famous Hotel Galvez, built in 1911 on Galveston Island overlooking the Gulf of Mexico, also bears the name of the Spanish hero of the American Revolution.
