Fort Bute was located on Bayou Manchac, about 115 miles (185 km) up the Mississippi River from New Orleans, on the far western border of British West Florida.

[1] On October 20, 1763, Major Robert Farmar of the 34th Regiment and commander of His Britannic Majesty's troops declared that all of the inhabitants of West Florida were subjects of England.

Captain James Campbell along with 50 African slaves constructed a channel to the Mississippi River.

[3] It was during this time that Farmar planned to build Fort Bute for protecting the workers and local settlers.

[7] Gálvez slowly marched his troops towards Bayou Manchac through the muddy swamp at nine miles each day.
