Having made these dispositions, my lord, I proceeded to mislead the enemy as to our intentions, in suffering my servant to be taken with an intercepted despatch. This, being a prescription by Doctor Colles, would convey to the dean’s mind the impression that I was still upon the sick list. This being done, and four canisters of Dartford gunpowder being procured on tick, our military chest being in a most deplorable condition, I waited for the moment of attack. A heavy rain, accompanied with a frightful hurricane, prevailed during the entire day, rendering the march of the troops who came from the neighborhood of Merrion Square and Fitzwilliam Street, a service of considerable fatigue. The outlying pickets in College Green, being induced probably by the inclemency of the season, were rather tipsy on joining, and having engaged in a skirmish with old M’Calister, tying his red uniform over his head, the moment of attack was precipitated, and we moved to the trenches by half-past nine o’clock. Nothing could be more orderly, nothing more perfect, than the march of the troops. As we approached the corner of the commons-hall, a skirmish on the rear apprised us that our intentions had become known; and I soon learned from my aide-de-camp, Bob Moore, that the attack was made by a strong column of the enemy, under the command of old Fitzgerald. Perpendicular (as your lordship is aware he is styled by the army) came on in a determined manner, and before many minutes had elapsed had taken several prisoners, among others Tom Drummond,--Long Tom,--who, having fallen on all fours, was mistaken for a long eighteen. The success, however, was but momentary; Nesbitt’s Brigade attacked them in flank, rescued the prisoners, extinguished the dean’s lantern, and having beaten back the heavy porters, took Perpendicular himself prisoner. An express from the left informed me that the attack upon the provost’s house had proved equally successful; there wasn’t a whole pane of glass in the front, and from a footman who deserted, it was learned that Mrs. Hutchinson was in hysterics.
