As soon as the main body of the enemy had withdrawn from the settlements, a tour was made by Colonel Washington to the south-western frontier. There, as well as to the north, continued incursions had been made; and there too, the principal defence of the country was entrusted to an ill-regulated militia. The fatal consequences of this system are thus stated by him, in a letter to the lieutenant governor: "The inhabitants are so sensible of their danger, if left to the protection of these people, that not a man will stay at his place. This I have from their own mouths, and the principal inhabitants of Augusta county. The militia are under such bad order and discipline, that they will come and go, when and where they please, without regarding time, their officers, or the safety of the inhabitants, but consulting solely their own inclinations. There should be, according to your honour's orders, one-third of the militia of these parts on duty at a time; instead of that, scarce one-thirtieth is out. They are to be relieved every month, and they are a great part of that time marching to and from their stations; and they will not wait one day longer than the limited time, whether relieved or not, however urgent the necessity for their continuance may be." Some instances of this, and of gross misbehaviour, were then enumerated; after which, he pressed the necessity of increasing the number of regulars to two thousand men. After returning from this tour, to Winchester, he gave the Lieutenant Governor, in curious detail, a statement of the situation in which he found the country, urging, but urging in vain, arguments which will always be suggested by experience, against relying chiefly on militia for defence. Sensible of the impracticability of defending such an extensive frontier, Colonel Washington continued to press the policy of enabling him to act on the offensive. The people of Virginia, he thought, could be protected only by entering the country of the enemy; giving him employment at home, and removing the source of all their calamities by taking possession of fort Du Quesne.
