On the sixteenth of May, Kirke's troops embarked: on the twenty-second they sailed: but contrary winds made the passage slow, and forced the armament to stop long at the Isle of Man. Meanwhile the Protestants of Ulster were defending themselves with stubborn courage against a great superiority of force. The Enniskilleners had never ceased to wage a vigorous partisan war against the native population. Early in May they marched to encounter a large body of troops from Connaught, who had made an inroad into Donegal. The Irish were speedily routed, and fled to Sligo with the loss of a hundred and twenty men killed and sixty taken. Two small pieces of artillery and several horses fell into the hands of the conquerors. Elated by this success, the Enniskilleners soon invaded the county of Cavan, drove before them fifteen hundred of James's troops, took and destroyed the castle of Ballincarrig, reputed the strongest in that part of the kingdom, and carried off the pikes and muskets of the garrison.
The next incursion was into Meath. Three thousand oxen and two thousand sheep were swept away and brought safe to the little island in Lough Erne. These daring exploits spread terror even to the gates of Dublin. Colonel Hugh Sutherland was ordered to march against Enniskillen with a regiment of dragoons and two regiments of foot. He carried with him arms for the native peasantry; and many repaired to his standard. The Enniskilleners did not wait till he came into their neighbourhood, but advanced to encounter him. He declined an action, and retreated, leaving his stores at Belturbet under the care of a detachment of three hundred soldiers. The Protestants attacked Belturbet with vigour, made their way into a lofty house which overlooked the town, and thence opened such a fire that in two hours the garrison surrendered. Seven hundred muskets, a great quantity of powder, many horses, many sacks of biscuits, many barrels of meal, were taken, and were sent to Enniskillen. The boats which brought these precious spoils were joyfully welcomed. The fear of hunger was removed. While the aboriginal population had, in many counties, altogether neglected the cultivation of the earth, in the expectation, it should seem, that marauding would prove an inexhaustible resource, the colonists, true to the provident and industrious character of their race, had, in the midst of war, not omitted carefully to till the soil in the neighbourhood of their strongholds. The harvest was now not far remote; and, till the harvest, the food taken from the enemy would be amply sufficient.243Yet, in the midst of success and plenty, the Enniskilleners were tortured by a cruel anxiety for Londonderry. They were bound to the defenders of that city, not only by religious and national sympathy, but by common interest. For there could be no doubt that, if Londonderry fell, the whole Irish army would instantly march in irresistible force upon Lough Erne. Yet what could be done? Some brave men were for making a desperate attempt to relieve the besieged city; but the odds were too great.
Detachments however were sent which infested the rear of the blockading army, cut off supplies, and, on one occasion, carried away the horses of three entire troops of cavalry.244 Still the line of posts which surrounded Londonderry by land remained unbroken. The river was still strictly closed and guarded. Within the walls the distress had become extreme. So early as the eighth of June horseflesh was almost the only meat which could be purchased; and of horseflesh the supply was scanty. It was necessary to make up the deficiency with tallow; and even tallow was doled out with a parsimonious hand.
On the fifteenth of June a gleam of hope appeared. The sentinels on the top of the Cathedral saw sails nine miles off in the bay of Lough Foyle. Thirty vessels of different sizes were counted.
Signals were made from the steeples and returned from the mast heads, but were imperfectly understood on both sides. At last a messenger from the fleet eluded the Irish sentinels, dived under the boom, and informed the garrison that Kirke had arrived from England with troops, arms, ammunition, and provisions, to relieve the city.245In Londonderry expectation was at the height: but a few hours of feverish joy were followed by weeks of misery. Kirke thought it unsafe to make any attempt, either by land or by water, on the lines of the besiegers, and retired to the entrance of Lough Foyle, where, during several weeks, he lay inactive.
