St. Leger’s advanced guard, consisting of a detachment of 30 men of the 8th Regiment, under Lieutenant Bird, with 200 Indians under Brant, arrived before the fort on the 2nd of August. They had been sent on, as is told in St. Leger’s dispatch, ‘to seize fast hold of the lower landing-place, and thereby cut off the enemy’s communication with the lower country.’[127] It had been hoped that they would be in time to intercept the reinforcements which were due at the fort, but they arrived too late for this purpose. They took up their position at the point named, below and due south of the fort, on the bank of the Mohawk river, athwart the road to Albany. On the following day, the 3rd of August, St. Leger came up himself, sent a proclamation into the fort, and began to invest it, fixing his main encampment about half a mile to the north-east of the fort, and higher up the river, which here runs in a curving course, so that a straight line drawn from the main British camp to the post at the lower landing-place would cross and recross the river, forming the base of a semi-circle. The Americans had blocked up Wood Creek with fallen timber, and St. Leger reported that it took nine days and the work of 110 men to clear away the obstructions, while two days were spent in making several miles of track through the woods in order in the meantime to bring up stores and guns. The siege, therefore, began long before the necessary preparations had been made, and long before the besieging force had been concentrated and duly entrenched. On the evening of the 5th of August there were not 250 of the white troops in camp, and at this juncture St. Leger was threatened by a strong body of Americans who had gathered for the relief of the fort.
