Answer:
Louisiana was in Spanish territory and its governor was a young nobleman named, Bernardo de Galvez. In the early years of the Revolution, Galvez provided aid to the American cause by allowing tons of supplies to be shipped up the Mississippi to patriot forces in the north.
Gálvez is best remembered for his role in denying the British the ability to encircle the American rebels from the south by pressing British forces in West Florida and for keeping a vital flow of supplies to Patriot troops across the colonies.
