This Presidents’ Day, I’ve been thinking about George Washington—not at his finest hour, but possibly at his worst.

In 1754, a 22-year-old Washington marched into the wilderness surrounding Pittsburgh with more ambition than sense. He volunteered to travel to the Ohio Valley on a mission to deliver a letter from Robert Dinwiddie, governor of Virginia, to the commander of French troops in the Ohio territory. This military mission sparked an international war, cost him his first command and taught him lessons that would shape the American Revolution.

As a professor of early American history who has written two books on the American Revolution, I’ve learned that Washington’s time spent in the Fort Duquesne area taught him valuable lessons about frontier warfare, international diplomacy and personal resilience.

The mission to expel the French

In 1753, Dinwiddie decided to expel French fur trappers and military forces from the strategic confluence of three mighty waterways that crisscrossed the interior of the continent: the Allegheny, Monongahela and Ohio rivers. This confluence is where downtown Pittsburgh now stands, but at the time it was wilderness.

King George II authorized Dinwiddie to use force, if necessary, to secure lands that Virginia was claiming as its own.

As a major in the Virginia provincial militia, Washington wanted the assignment to deliver Dinwiddie’s demand that the French retreat. He believed the assignment would secure him a British army commission.

Washington received his marching orders on Oct. 31, 1753. He traveled to Fort Le Boeuf in northwestern Pennsylvania and returned a month later with a polite but firm “no” from the French.
