In March 1754, Governor Dinwiddie sent Washington back to the frontier with orders to "act on the [defensive], but in Case any Attempts are made to obstruct the Works or interrupt our [settlements] by any Persons whatsoever, You are to restrain all such Offenders, & in Case of resistance to make Prisoners of or kill & destroy them".
Historian Fred Anderson describes Dinwiddie's instructions, which were issued without the knowledge or direction of the British government in London, as "an invitation to start a war".
Washington was ordered to gather as many supplies and paid volunteers as he could along the way.
By the time he left for the frontier on April 2, he had gathered 186 men.

Contrecœur operated under orders that forbade attacks by his force unless they were provoked.
On May 23, he sent Joseph Coulon de Villiers de Jumonville with 35 men to see if Washington had entered French territory, and with a summons to order Washington's troops to leave; this summons was similar in nature to the one Washington had delivered to them four months previous.
Sources disagree on the exact composition of Jumonville's force, which may have included French troupes de la marine, Canadian militia, and Indians.

During the march through the forests of the frontier, Washington received a few more men from another regiment that they met at Winchester.
At this point Captain Trent arrived with news of the advance of the French force under Jumonville.
Trent was accompanied by Tanacharison, who promised warriors to assist the British.
To keep Tanacharison's support, Washington decided not to turn back, choosing instead to build a fortification 37 miles (60 km) south of the forks and await further instructions.
The men of the Virginia Regiment built a road through the wilderness as they went, "broad enough to pass with all our Artillery and our Baggage."
This road was essential, not just to allow Washington and his men to move quickly to Fort Duquesne, but to open up the Ohio country to Virginia troops and settlers in the future.
The Washington and the Ohio Company had originally hoped to use the Potomac River to travel between the tidewater and the Ohio country; however, the Great Falls made such a journey impossible until the completion of the Patowmack Canal in 1803.
