Fort Duquesne was part of French defenses during the French and Indian War that stretched from Quebec
City on the St. Lawrence River to New Orleans on the Mississippi River. The French were determined to
contain British colonization to the east. The British were repelled from Fort Duquesne in 1755, but
they attacked again in 1758. The Brits gained the fort, renamed it for British prime minister William
Pitt, and broke the French chain of defense almost exactly in half.
