O'DONNELL alone kept his forces intact until they were in great part destroyed on him in this way:As he had preserved his country by successful battles on land, making Connaught the seat of war, a fleet was organised in England which, sailing between Scotland and Ireland, put into Lough Foyle in O'Donnell's country. In this fleet was no Irishman of standing except Maelmurray MacSweeny Tuath who had quarrelled with and deserted O'Donnell. He had fought against him at Ballaghboy on the day Clifford was slain and having distinguished himself by his valour in Leinster, had been knighted by Essex and had subsequently crossed to England.
However, on the night in which the English reached this port, he jumped overboard, swam ashore, and coming to O'Donnell begged his forgiveness on bended knees and got restored to all his possessions. The English, who were 4,000 under Henry Dowcra, a knight, landed and occupied the unfortified town of Derry, the famous episcopal seat of Saint Columba, overhanging the lough and fortified it with works and batteries. On the second day after their landing O'Donnell came up and carried off 168 of their horses and again the Catholics seized some horses grazing near the town, which the English pursued. A cavalry fight ensued. Hugh O'Donnell, surnamed Oge, wounded Dowcra, piercing his helmet with a spear and breaking his head. An English gentleman fired a pistol placed close up to Daniel O'Gallagher, an Irish gentleman, and though the bullet grazing the eye passed out through the nose, yet
On another day Roderick accompanied by two horsemen fell in with eight English foot soldiers who came out of Derry to gather wood, and attacking them, slew six, releasing one whom he captured but who said he was a Briton. The eighth who was sergeant of a company, held out with great valour, being often struck by Roderick's spear and thrown down but again quickly getting up unwounded, as he was protected by a jerkin of oxhide, he attacked Roderick with drawn sword and got in sixteen thrusts on Roderick's right arm, which was, however, protected by the sleeves of the cuirass. When Roderic was unable to hurt his enemy with his spear, and he seemed likely to escape, the former attacked with his sword but this also was unable to penetrate the hide, whether owing to the toughness of the leather or to some spell, I do not know. Finally the sergeant tried to cross the nearest stream but as he was crossing Roderick struck him with his spear in the back and kept him down under the water until he was drowned.
Ships carrying provisions from Derry to Lifford were pursuing the even tenor of their way over the lough, when, near Lifford, where the lough narrows, they were attacked by the Catholics showering missiles on the boats from the banks. The garrison of Lifford coming out to the fight were driven back to the town and the boats, provisions and clothes were captured. Many of the royalists perished on this day. Roderic was slightly wounded in the thigh by a bullet.
About this time O'Connor, Chief of Sligo, being suspected by some persons of plotting mischief against O'Donnell, was imprisoned by the latter. O'Doherty ended his
O'Donnell was now in great straits, having lost Derry, Lifford and Innishowen, and deprived of the aid of O'Connor, whom he kept in prison. Moreover the Connaughtmen whom he had hired became disaffected and mutinous. However he invaded Innishowen where Cahir's party had a great quantity of arms stored in Birt which was strongly defended by its natural position and by ancient fortifications. O'Donnell determined to assail this and the Cahirites decided to defend it. The Connaughtmen would not form the first line as ordered by O'Donnell. A company of Tyrconnellians placed in the van broke into the fortress but were not supported by the Connacians, and therefore this company, which was very inferior in number to the Cahirites, was overwhelmed with showers of bullets and being partly destroyed, escaped with difficulty from another portion of the fort. Meantime Garve, burning with a great desire for the Chieftaincy of Tyrconnell, was by no means idle. A man of bold spirit, and particularly well acquainted with the roads, he secretly conducted Irishmen of his faction and Englishmen over land and water from Lifford and surprised the monastery of Friars Minors called Donegal, and occupied it, and fortified and placed a garrison in the dismantled castle which stood an arrow-flight off, and in another monastery of Franciscans of the Third Order which is called Maherabeg, half a mile away, from which the monks fled and which up to that day had ever been regarded as sacred and inviolable sanctuaries. By this move O'Donnell was forced to send his moveables and baggage into Sligo while himself and his army surrounding Donegal disputed with Garve during nearly three months the monastery and castle, now advancing mantlets to the walls, now setting up against them sows10 and breastworks. But the royalists suffered for their violation of the monastery, for one night the powder, either by means of some one detailed by O'Donnell, or by accident, or providentially fired, suddenly burned up the monastery and partly blew it into the air. The defenders were partly consumed by the fire, and partly crushed by the falling roof and walls. O'Donnell
On the other side, Earl Clanrickarde by command of the Queen, made an incursion against O'Donnell and led the royalist forces against Elphin, an episcopal town. O'Donnell advanced to meet him. For some days there were cavalry and musketeer skirmishes and the Earl then returned without having effected anything.
