As the allies began to put their artillery into place, the British kept up a steady fire to disrupt them. British fire increased on the 2nd and the allies suffered moderate casualties. General Washington continued to make visits to the front, despite concern shown by several of his officers over the increasing enemy fire. On the night of October 2, the British opened a storm of fire to cover up the movement of the British cavalry to Gloucester where they were to escort infantrymen on a foraging party. On the 3rd, the foraging party, led by Banastre Tarleton, went out but collided with Lauzun's Legion, and John Mercer's Virginia militia, led by the Marquis de Choisy. The British cavalry quickly retreated behind their defensive lines, losing 50 men.
