The Irish army which had retreated to Strabane remained there but a very short time. The spirit of the troops had been depressed by their recent failure, and was soon completely cowed by the news of a great disaster in another quarter.
Three weeks before this time the Duke of Berwick had gained an advantage over a detachment of the Enniskilleners, and had, by their own confession, killed or taken more than fifty of them.
They were in hopes of obtaining some assistance from Kirke, to whom they had sent a deputation; and they still persisted in rejecting all terms offered by the enemy. It was therefore determined at Dublin that an attack should be made upon them from several quarters at once. Macarthy, who had been rewarded for his services in Munster with the title of Viscount Mountcashel, marched towards Lough Erne from the east with three regiments of foot, two regiments of dragoons, and some troops of cavalry. Aconsiderable force, which lay encamped near the mouth of the river Drowes, was at the same time to advance from the west. The Duke of Berwick was to come from the north, with such horse and dragoons as could be spared from the army which was besieging Londonderry. The Enniskilleners were not fully apprised of the whole plan which had been laid for their destruction; but they knew that Macarthy was on the road with a force exceeding any which they could bring into the field. Their anxiety was in some degree relieved by the return of the deputation which they had sent to Kirke. Kirke could spare no soldiers; but he had sent some arms, some ammunition, and some experienced officers, of whom the chief were Colonel Wolseley and Lieutenant Colonel Berry. These officers had come by sea round the coast of Donegal, and had run up the Line. On Sunday, the twenty-ninth of July, it was known that their boat was approaching the island of Enniskillen. The whole population, male and female, came to the shore to greet them. It was with difficulty, that they made their way to the Castle through the crowds which hung on them, blessing God that dear old England had not quite forgotten the Englishmen who upheld her cause against great odds in the heart of Ireland.
Wolseley seems to have been in every respect well qualified for his post. He was a stanch Protestant, had distinguished himself among the Yorkshiremen who rose up for the Prince of Orange and a free Parliament, and had, if he is not belied, proved his zeal for liberty and pure religion, by causing the Mayor of Scarborough, who had made a speech in favour of King James, to be brought into the market place and well tossed there in a blanket.258 This vehement hatred of Popery was, in the estimation of the men of Enniskillen, the first of all qualifications for command: and Wolseley had other and more important qualifications. Though himself regularly bred to war, he seems to have had a peculiar aptitude for the management of irregular troops. He had scarcely taken on himself the chief command when he received notice that Mountcashel had laid siege to the Castle of Crum. Crum was the frontier garrison of the Protestants of Fermanagh. The ruins of the old fortifications are now among the attractions of a beautiful pleasureground, situated on a woody promontory which overlooks Lough Erne. Wolseley determined to raise the siege. He sent Berry forward with such troops as could be instantly put in motion, and promised to follow speedily with a larger force.
Berry, after marching some miles, encountered thirteen companies of Macarthy's dragoons commanded by Anthony, the most brilliant and accomplished of all who bore the name of Hamilton, but much less successful as a soldier than as a courtier, a lover, and a writer. Hamilton's dragoons ran at the first fire: he was severely wounded; and his second in command was shot dead.
Macarthy soon came up to support Hamilton; and at the same time Wolseley came up to support Berry. The hostile armies were now in presence of each other. Macarthy had above five thousand men and several pieces of artillery. The Enniskilleners were under three thousand; and they had marched in such haste that they had brought only one day's provisions. It was therefore absolutely necessary for them either to fight instantly or to retreat.
