The measure of relief voted by the Assembly was an additional appropriation of twenty thousand pounds, and an increase of the provincial force to fifteen hundred men. With this, it was proposed to erect and garrison a chain of frontier forts, extending through the ranges of the Allegany Mountains, from the Potomac to the borders of North Carolina; a distance of between three and four hundred miles. This was one of the inconsiderate projects devised by Governor Dinwiddie. Washington, in letters to the governor and to the speaker of the House of Burgesses, urged the impolicy of such a plan, with their actual force and means. The forts, he observed, ought to be within fifteen or eighteen miles of each other, that their spies might be able to keep watch over the intervening country, otherwise the Indians would pass between them unperceived, effect their ravages, and escape to the mountains, swamps, and ravines, before the troops from the forts could be assembled to pursue them. They ought each to be garrisoned with eighty or a hundred men, so as to afford detachments of sufficient strength, without leaving the garrison too weak; for the Indians are the most stealthy and patient of spies and lurkers; will lie in wait for days together about small forts of the kind, and, if they find, by some chance prisoner, that the garrison is actually weak, will first surprise and cut off its scouting parties, and then attack the fort itself. It was evident, therefore, observed he, that to garrison properly such a line of forts, would require, at least, two thousand men. And even then, a line of such extent might be broken through at one end before the other end could yield assistance. Feint attacks, also, might be made at one point, while the real attack was made at another, quite distant; and the country be overrun before its widely-posted defenders could be alarmed and concentrated. Then must be taken into consideration the immense cost of building so many forts, and the constant and consuming expense of supplies and transportation. His idea of a defensive plan was to build a strong fort at Winchester, the central point, where all the main roads met of a wide range of scattered settlements, where tidings could soonest be collected from every quarter, and whence reinforcements and supplies could most readily be forwarded. It was to be a grand deposit of military stores, a residence for commanding officers, a place of refuge for the women and children in time of alarm, when the men had suddenly to take the field; in a word, it was to be the citadel of the frontier.
