AT this time, Clifford, the Governor of Connaught, resolved to fight O'Donnell, by land and sea, and in the first place to attack Sligo and rebuild the castle O'Donnell had dismantled. To this end O'Connor Sligo went round amongst the Connaughtmen on the Sligo side of the Curlew mountains, exhorting and beseeching them to desert O'Donnell. A troop of O'Donnell's horse accidently met this O'Connor accompanied by a few horse, and engaging him, forced him with the loss of a few men to take refuge in Collooney fort, where he was surrounded and attacked by O'Donnell. O'Connor stoutly defended the fort for about forty days, when it appeared he should surrender from want. Clifford becoming aware of this, hastened his expedition in order to recover Sligo, as he had already purposed, and on his way to succour O'Connor, he ordered Theobald Burke, surnamed Na-long (the naval) claimant to the MacWilliam's country to sail from Galway with the fleet which was conveying the provisions, cannon, lime and other materials for reconstructing the Castle, whilst himself with the rest of the forces took the overland road. O'Donnell, well aware of this plan, placed 400 foot under MacSweeny Fanad and Mac William to garrison Sligo. He ordered O'Boyle to continue the siege of Collooney fort with 200 horse, while he himself with the foot and O'Doherty held the Curlew mountains through which Clifford's road lay. There were two roads through this mountain, one very narrow and difficult, the other wider. He placed three companies in the more difficult road with orders to prevent the enemy's advance until he sent others to their aid. On the more open road himself
By the help of the Most Blessed Virgin Mary, Mother of God, we will this day utterly destroy the heretical enemy whom we have always heretofore worsted. We fasted yesterday in honour of the Virgin, and to day we celebrate her feast. Therefore in Her name let us fight stoutly and bravely the enemies of the Virgin and we shall gain the victory.
The soldiers being greatly inflamed to war by this speech, he sent on 600 musketeers under Eugene MacSweeny, Tuath, and Hugh and Tuathal O'Gallagher, with orders to attack and delay the enemy, while himself brought up the gallowglasses. The enemy had climbed out of the narrow passes to the middle and open part of the mountain, and about 11 a.m. the rain was ceasing when the gunners came up with O'Donnell's men. There on account of the favourable nature of the ground and the great spirit of the young men, a fierce encounter with leaden bullets at long range commenced, and many wounds were inflicted on both sides. The Irish gunners are giving way; their leaders remonstrate at this baseness, and at their fighting with such faintheartedness for the Virgin. Stung with shame by these reproaches, and roused by zeal to fight earnestly for the Virgin they renew the contest. It is scarcely credible with what spirit and perseverance and skill the musketeers of both parties fought. The royalist gunners were driven back on the pikemen's division, and that division itself, overwhelmed with a shower of darts, and wounded, changed its front and from one side to another turned round three times in a circle, not knowing what it was doing. O'Rourke coming up with 140 foot to the support of the Catholics added terror to the already disorganised, and on seeing him the whole royalist army turned tail leaving behind a great heap of arms. The Catholics pursue. Although O'Donnell had hurried up with the gallowglasses yet he did not find the fight going on. I do not believe the royalists would have been put to flight by the gunners, had it not been for the aid of the Virgin Mother. The Catholics hung on the rear of the terror-stricken fugitives for three miles. Clifford was carried for some time by two Irish soldiers to whom he promised a large reward, but was eventually overtaken and killed by a pike-thrust in his side. The felled trees and obstructed roads were great obstacles to the fugitives, and they left there not only their arms but even their garments. The Baron of Dunkellin had a narrow escape. Griffin with all the cavalry came out a mile from Boyle to the rescue of the fugitives, and put to flight the first of the Catholics, who were pursuing and slaughtering the enemy without any order; but O'Rourke, supporting the Catholics, and rallying them, and withstanding the enemy, received two bullet wounds, one in the right hand and the other in the right thigh, and made the cavalry retire. The Catholics again pursued as far as Boyle, into which Griffin betook himself. Of the royalists there perished with their leader
