Monday, the 21st September.—The long boats now of the men-of-war are ordered somewhere else, and we make the best shift we can with our small boats. The line of contravallation is traced anew nearer the town, and we continue to finish our horn-work that covers the bridge. Three hundred tools are sent to Tettau's fort to demolish it. The general has ordered that the seven heavy cannon left on the great battery be removed to Cromwell's fort, and that the two six-pounders and eight three-pounders, with ammunition, etc., pass the bridge tomorrow by break of day.
