Ginckle, impatient of delay, and not wishing to lose time in storming the castle, into which Burke had thrown a sergeant and fifteen men, deployed to the northward, and, erecting his batteries, directed a heavy fire against the fort. But as the great body of the lake intervened, no impression could be made from that direction, and it was found necessary to reduce the castle, which commanded the narrowest part of the lake, and also the pass leading into the fort. It was accordingly stormed, carried after an obstinate defence of two hours, and the gallant sergeant hanged in sight of the fort, for an "obstinate defence of an untenable position." This obstacle being removed, eighteen guns and four mortars were brought to bear against the fort, until eight o'clock in the morning, when the firing ceased, and Ginckle demanded a surrender, the summons being accompanied by a threat, that if it were not vacated within two hours, the garrison would share the fate of the sergeant, which they had just witnessed. Colonel Burke denied its authenticity, asserting that Ginckle would not set his signature to such an atrocious order, and demanded the summons in writing. The form was soon complied with, the threat was repeated over Ginckle's signature, but leave was granted for the women and children to depart or share the fate of the garrison. Burke next stipulated for permission to withdraw the garrison, as the non-combatants were determined to share their fate; but this being refused, the firing was resumed on both sides, and continued without intermission until noon, when the Irish gunner being killed, and the sand-walls of the fort completely beaten down, Burke displayed a flag of truce to the assailants. Ginckle, greatly incensed by the obstinacy of the defence, refused to notice the signal, and the cannonade was continued until seven o'clock in the evening, when a storming party and boats being ready to cross the lake, Burke again displayed his flag, surrendered unconditionally, and Colonel Earl, at the head of eight hundred troops, took possession of the fort. The booty of the captors was considerable, consisting of four hundred and thirty sheep, forty cows, fifty horses, a quantity of oatmeal, the arms of the garrison, two pieces of artillery, "_but no powder_." The loss of life was inconsiderable on either side; the threat of the English general was not put in execution;--the men of the garrison became prisoners of war, and the women and children were sent beyond the Irish lines, in conformity with the usage of the times.
