England's Supremacy In 1763

Source

From the Magazine Of American History:


When the "Old French War" drew to a close, and the contest for American supremacy was decided in favor of England, France was compelled to relinquish all her territorial possessions on the continent of America. By conquest from France and by cession of Florida from Spain, England came into possession of the territory east of the Mississippi, with the exception of a small triangular portion known as the Isle of Orleans upon which was founded the present city of New Orleans. This with the vast country lying west of the Mississippi embraced within the province of Louisiana, passed to the jurisdiction of Spain. The treaty terminating hostilities and confirming the several transfers of territory is known as the first treaty of Paris, 1763.

England lost little time in occupying her newly acquired possessions. The Florida of those days extended as far west as the Mississippi, and it was now divided, the line of division between the eastern and western portion being the Perdido river. British garrisons were placed at Natchez, Baton Rouge, and Mobile. Several new posts were established, notably Fort Bute on Bayou Manchac, the stream separating West Florida from the Isle of Orleans south of it.
