From the supposed loss of our ammunition, and the consequent depression such an event was likely to produce upon the minds of our men, I felt persuaded that this explosion would lead the enemy to assault, and made my arrangements accordingly. The night was dark, and the early part of it raining, but the faithful sentinel slept not; one-third of the troops were up at their posts. At half-past two o'clock, the right column of the enemy approached, and though enveloped in darkness black as his designs and principles, was distinctly heard on our left, and promptly marked by our musketry under Major Wood, and cannon under Captain Towson. Being mounted at the moment, I repaired to the point of attack, where the sheet of fire rolling from Towson's battery, and the musketry of the left wing of the 21st infantry under Major Wood, enabled me to see the enemy's column of about 1,500 men approaching on that point, his advance was not checked, until it had approached within ten feet of our infantry. A line of loose brush representing an abatis only intervened; a column of the enemy attempted to pass round the abatis through the water, where it was nearly breast deep. Apprehending that this point would be carried, I ordered a detachment of riflemen and infantry to its support, but having met with the gallant commander, Major Wood, was assured by him that he could defend his position without reinforcements. At this moment the enemy were repulsed, but instantly renewed the charge and were again repulsed. My attention was now called to the right, where our batteries and lines were soon lighted by a most brilliant fire of cannon and musketry; it announced the approach of the centre and left columns of the enemy, under Colonels Drummond and Scott; the latter was received by the veteran 9th, under the command of Captain Foster, and Captains Broughton and Harding's companies of New York and Pennsylvania volunteers, aided by a six-pounder judiciously posted by Major M'Ree, chief engineer, who was most active and useful at this point; they were repulsed. That of the centre, led by Colonel Drummond, was not long kept in check; it approached at once every assailable point of the fort; and (p. 229) with scaling ladders ascended the parapet, but was repulsed with fearful carnage. The assault was twice repeated, and as often checked, but the enemy having moved round the ditch covered by darkness, added to the heavy cloud of smoke which had rolled from our cannon and musketry, enveloping surrounding objects, repeated the charge, re-ascended the ladders; the pikes, bayonets and spears fell upon our gallant artillerists. The gallant spirits of our favourite Captain Williams and Lieutenants M'Donough and Watmough, with their brave men, were overcome. The
