On receiving an answer from the French commander, who promised nothing, Washington started back home. The horses soon proved too weak to make much headway through the dense forests and deep snow, and it seemed best to push on without them. He also left behind him all of his party except a trusty woodsman. Then putting on an Indian costume with a heavy cloak drawn over it, he strapped upon his back the pack containing his papers and, gun in hand, started off. A little later they were joined by an Indian guide, who soon gave evidence of his treachery by suddenly turning and discharging his gun at Washington. Washington had another narrow escape from death. He had expected on reaching the Alleghany River to cross on the ice, but to his dismay he found the ice broken up and the stream filled with whirling blocks. There was no way of getting over except on a raft which he and his companion had to make with a single hatchet. Having at last finished it, they pushed off, and then began a desperate struggle with the current and, great blocks of floating ice. Washington, in trying to guide the raft with a pole, was thrown violently into the water. By catching hold of one of the raft logs he recovered himself, and by heroic effort succeeded in reaching an island nearby. Here the travellers suffered through a night of intense cold, not daring to kindle a fire for fear of the Indians. On January 16th they reached Williamsburg, where Washington delivered to Governor Dinwiddie the unsatisfactory letter he had brought from the French commander. Although the result of the expedition was not what the Virginians had hoped for, Washington had so well succeeded in carrying out his perilous mission that he was highly praised for his effort. The defiant answer of the French commander made it seem probable to the people of Virginia that war would follow. Therefore a company of men was sent out to build a fort at the place where the Alleghany and Monongahela rivers unite to form the Ohio. Washington's quick eye had noted the importance of this site, afterward known as the "Gateway of the West." In the meantime Washington was drilling men for service, and in April he set out with the rank of lieutenant-colonel with two companies for the frontier. He had not gone very far when he learned that the French had driven off with a large force the men who had been sent to the head of the Ohio to build a fort; but he continued his march. When a little later the approach of a small body of French was reported, the Virginians surprised them, killing, wounding, or capturing all but one. Colonel Washington was in the thickest of the fight, and wrote in a letter, "I heard the bullets whistle and, believe me, there is something charming in the sound."
