The troops, bewildered and amazed by the fire poured into them by an invisible foe, and by the wild war whoops of the Indians, ceased to advance, and, standing close together, poured fruitlessly volley after volley into the surrounding forest.
On hearing the firing, Braddock, leaving 400 men in the rear under Sir Peter Halket, to guard the baggage, advanced with the main body to support Gage; but, just as he came up, the soldiers, appalled by the fire which was mowing them down in scores, abandoned their cannon and fell back in confusion.

This threw the advancing force into disorder, and the two regiments became mixed together, massed in several dense bodies within a small space of ground, facing some one way and some another, all alike exposed, without shelter, to the hail of bullets.
Men and officers were alike new to warfare like this.

They had been taught to fight in line against solid masses of the enemy, and against an invisible foe like the present they were helpless.

The Virginians alone were equal to the emergency.

They at once adopted their familiar forest tactics, and, taking their post behind trees, began to fight the Indians in their own way.
Had Braddock been a man of judgment and temper, the fortunes of the day might yet have been retrieved, for the Virginians could have checked the Indians until the English troops were rallied and prepared to meet the difficulty; but, to Braddock, the idea of men fighting behind trees was at once cowardly and opposed to all military discipline, and he dashed forward on his horse, and with fierce oaths ordered the Virginians to form line.
