The investing force was 5,000 men, four siege-guns, two mortars, and two field-pieces. From this force 400 dragoons marched with the Duke of Berwick to Enniskillen, and during the siege they received but 2,500 additional troops, making the entire force 7,500 men. The weather was continually unfavorable to siege operations, and, excepting in the amount of rations, the besiegers endured far more suffering than the besieged. The bombardment continued at intervals from the 21st of June to the 28th of July; but during the last week there had been an almost entire cessation of hostilities, to admit of negotiations. On the estimate of the Reverend George Walker, who has left a journal of the siege, the ball and mortar, great and small, thrown into the town up to the 22d of July, was 587. After this there was but an occasional shot until the siege was raised. This fell short of fifteen shots a day, and about one every two hours, admitting them to have been fired in regular succession. During the siege the garrison had been reduced to 3,000 effective men, while the besiegers retired with 3,500--showing a loss to the defenders of 7,000, and to the assailants of 3,600. The Duke of Berwick, who was present in all the skirmishing that took place up to the 21st of June, and who afterwards became a prominent character in the great wars of the continent, had certainly no inducement to magnify this episode in his life, by underrating the Jacobite forces; nor is it to be credited that the Reverend George Walker has given an overestimate of the besieged. Whatever were the privations of the non-combatants,--and they must have been great--it does not appear from his journal that the defenders were, for any considerable time, on an allowance much below that of soldiers in ordinary warfare. We find that in two or three instances they were obliged to resort to the boiling of salt hides for a substitute; and to eating "dogs and cats, etc.," now considered a luxury, though thrown in by Williamite writers to shadow a picture dark enough from any perspective.
