The expedition methodically constructed a road across what is now the southern part of Pennsylvania's Appalachian Plateau region, staging from Carlisle and exploiting the climb up via one of the few southern gaps of the Allegheny through the Allegheny Front, into the disputed territory of the Ohio Country, which was then a largely depopulated Amerindian tributary territory of the Iroquois Confederation. This well organized expedition was in contrast to a similar expedition led by Edward Braddock in 1755 that ended in the disastrous Battle of the Monongahela.
