The situation of Lord Cornwallis was becoming desperate. His works were sinking, in every quarter, under the fire of the besiegers. The batteries already playing on him had silenced nearly all his guns, and the second parallel was about to open, which must in a few hours render the town untenable. To suspend a catastrophe which appeared almost inevitable, he resolved on attempting to retard the completion of the second parallel, by a vigorous sortie against two batteries which appeared to be in the greatest forwardness, and were guarded by French troops. The party making this sortie was led by Lieutenant Colonel Abercrombie, who attacked the two batteries with great impetuosity about four in the morning, and carried both with inconsiderable loss; but the guards from the trenches immediately advancing on the assailants, they retreated without being able to effect any thing of importance. About four in the afternoon the besiegers opened several batteries in their second parallel; and it was apparent that, in the course of the ensuing day, the whole line of batteries in that parallel would be ready to play on the town. The works of the besieged were not in a condition to sustain so tremendous a fire. In this extremity, Lord Cornwallis formed the bold design of forcing his way to New York. He determined to leave his sick and baggage behind, and, crossing over in the night with his effectives to the Gloucester shore, to attack De Choise. After cutting to pieces or dispersing the troops under that officer, he intended to mount his infantry on the horses taken from that detachment, and on others to be seized on the road, and, by a rapid march to gain the fords of the great rivers, and, forcing his way through Maryland, Pennsylvania, and Jersey, to form a junction with the army in New York.[87] [Footnote 87: Stedman, Annual Register, letter of Lord Cornwallis.] This desperate attempt would be extremely hazardous; but the situation of the British general had become so hopeless, that it could scarcely be changed for the worse. Boats prepared under other pretexts were held in readiness to receive the troops at ten in the evening, and convey them over the river. The arrangements were made with such secrecy that the first embarkation arrived at the point unperceived, and part of the troops were landed, when a sudden and violent storm interrupted the execution of this hazardous plan, and drove the boats down the river. The storm continued till near daylight, when the boats returned. But the plan was necessarily abandoned, and the boats were sent to bring back the soldiers, who were relanded on the southern shore in the course of the forenoon without much loss.
