At this period, the labour which had been bestowed on the outward position at York town, had improved its natural advantages, and rendered it in every respect convenient for the King’s troops. The right rested on a swamp which cover the right of the town: A large redoubt was constructed beyond it, close to the river road from Williamsburgh, and completed with fraizing and abbatis. The Charon, Guadaloupe, and other armed vessels, were moored opposite to the swamp; and the town batteries commanded at the roads and causeways which approached it. On the right, at the head of the morass, two redoubts were placed, one on each side, of the main Williamsburgh road. The center was protected by a thin wood, whose front was cut down, with the branches facing outwards. A field work, mounted with cannon, was erected on the left of the center, to command the Hampton road. A deep ravine, and a creek, which increased till it reached York river, covered the left. Trees were felled, fleches were thrown up, and batteries were constructed, at the points which were deemed most vulnerable. The distance between the heads of the swamp and creek, which embraced the flanks of the town, did not exceed half a mile. The face of the country, in front of this line, was cut near the center by a morass, and, excepting this break, the ground was plain and open for near two thousand yards. An excellent field artillery was placed to the greatest advantage by Captain Rochefort, who commanded in that department.... The works erected for the protection of York town, consisted, on the right, of redoubts and batteries, with a line of stockade in the rear, which supported a high parapet of earth. The redoubts were furnished with fraizing and abbatis. A marshy ravine lay in front of the right, over which was placed a large redoubt, with a good ditch, fraizing, and abbatis: The morass extended along the center, which was defended by a line of stockade, and by batteries that looked upon all the avenues to the swamp: On the left of the center, was a horn work, with a ditch, a row of fraize, and an abbatis: Some embrazures for cannon were at present open in this work. The left was fortified by redoubts, communications of earth, and batteries, which were all furnished with fraizing, but without stockade or abbatis. Two redoubts were advanced before the left, which were small, and not so well finished as that in front of the right. The ground in front of the left was in some parts on a level with the works, in others cut by ravines, and altogether very convenient for the besiegers. The space within the works was exceedingly narrow, not large enough for retrenchments, and, except under the cliff, exposed to enfilade.
