On June 28, 1754, while navy ensign Joseph Coulon de Villiers de Jumonville was leading a mission aimed at ascertaining the American position in the Ohio Valley, he and 10 of his men were assassinated by soldiers under the command of George Washington (Jumonville, Pennsylvania). In retaliation, an expedition was organized consisting of 500 Frenchmen and about 100 Aboriginal warriors. The attack took place "Indian-fashion," according to the rules of forest warfare. The commander addressed his troops, issued them with necklaces and a tomahawk, consulted with them on which route to take, how fast they should march and how to behave towards the enemy, and sent out "scouts"; finally, the assembled troops uttered a loud war cry and attacked, presenting their flank. This tactic was successful, and in only a single day's fighting, the Canadian forces obtained the surrender of the fort and that of Washington's American troops.
