On the night of the 11th the second parallel was opened within three hundred yards of the enemy's lines; and, as in the former instance, it was so far advanced before morning that the men employed in them were in a great measure protected from injury when the enemy opened fire. The three following days were spent in completing this parallel and the redoubts and batteries belonging to it, during which time the enemy's fire was well sustained and more than usually destructive. Two advanced batteries, three hundred yards in front of the enemy's left, were particularly annoying, inasmuch as they flanked the second parallel of the besiegers; and as the engineers reported that they had been severely injured by the fire of the allies it was resolved to attempt to carry them by assault. Accordingly, in the evening of the 14th, these redoubts were assaulted--that on the extreme right by a detachment embracing the light infantry of the American army, under General Lafayette; the latter by a detachment of grenadiers and chasseurs from the French army, commanded by Baron Viomenil. The attacks were made at 8 P.M., and in that of the Americans the advance was led by Lieutenant-Colonel Alexander Hamilton, with his own battalion and that of Colonel Gimat, the latter in the van; while Lieutenant-Colonel John Laurens, at the head of eighty men, took the garrison in reverse and cut off its retreat. Not a single musket was loaded; and the troops rushed forward with the greatest impetuosity--passing over the abatis and palisades--and carrying the work with the bayonet, with the loss of nine killed, and six officers and twenty-six rank and file wounded. The French performed their part of the duty with equal gallantry, although from the greater strength of their opponents it was not done so quickly as that of the Americans. The German grenadier regiment of Deux-Ponts, led by Count William Forback de Deux-Ponts, led the column; and Captain Henry de Kalb, of that regiment, was the first officer who entered the work. The chasseur regiment of Gatinois supported the attack; and, in like manner with that on the right, the redoubt was carried at the point of the bayonet. During the night these redoubts were connected with the second parallel; and during the next day (October 15th) several howitzers were placed on them and a fire opened on the town. These works, important as they had been to the enemy, were no less so to the allies, from the fact that, with them, the entire line of the enemy's works could be enfiladed, and the line of communication between York and Gloucester commanded.
