His behaviour was more like that of a lunatic than of a sane man. Take the following example, for instance. He had a house and grounds near Dublin, and his neighbours all fought shy of him—nay, one of them, a retired officer, Captain Boulton, would neither accept his invitations nor invite him to his mansion. This conduct galled Fitzgerald, and he devised a novel method of avenging himself of the insult. He would shoot on the captain’s grounds without leave. So he went down with his man and dogs and began killing the game in fine style. This soon brought out the steward, who began to remonstrate with the trespasser. Fitzgerald’s answer was a bullet, which whizzed close to the head of the poor steward, who turned, and ran for his life, Fitzgerald after him with a second gun, with the certain determination of shooting him. Luckily the man got safely into the mansion. Baffled of his victim, Fitzgerald began abusing Captain Boulton, calling on him to come out, and give him satisfaction for his man’s behaviour. But the captain, not seeing the force of the argument, refrained, and Fitzgerald fired his gun at the dining-room window. As this, however, did not bring out the captain, he fired at the windows as fast as his man could load, and only left off when he had smashed every one of them.

Another time he waged war against all the dogs in Castlebar, shooting them whenever he got a chance; but the people did not stand it tamely; they rose, visited his kennels, and shot his dogs.

His father died; but his brother, his father’s mistress, and MacDonnell, took advantage of every circumstance in their power to maliciously vex him. Law-suits were stirred up against him, and had to be met with the assistance of Timothy Brecknock, who was Fitzgerald’s legal adviser, and the followers of both parties were not particular in exchanging a shot or two, one with the other.

At length MacDonnell kidnapped one of Fitzgerald’s servants, and kept him prisoner for twenty days. Then the man escaped, and Fitzgerald applied for, and obtained warrants against, MacDonnell and two other men, named Hipson and Gallagher. To execute these warrants personally must have been a congenial task to Fitzgerald, and he set out for that purpose, followed by a large body of men. On their approach, MacDonnell fled to the neighbouring village of Ballivary, and his friends did the best they could to defend themselves, firing on his party and wounding six or seven of them. They then went after MacDonnell, and, after more firing, succeeded in apprehending MacDonnell, Hipson, and Gallagher. These unfortunate men begged to be taken before the nearest magistrate; but Fitzgerald had them bound, and taken to his house, where they remained all night.

Early the next morning they were sent, guarded by a man of his, one Andrew Craig, and about eighteen or twenty more, all well armed, to be examined by the magistrates. Before their departure Fitzgerald gave the guard strict instructions to kill the prisoners should they attempt to escape. When they had gone about three-quarters of a mile a shot was fired, and one of the escort was laid low. But very little was wanted to rouse their wild blood, and it was at once considered that a rescue was intended. Remembering the instructions given them by Fitzgerald, they fired on their prisoners, killing Hipson, who fell into a ditch, dragging Gallagher with him, wounded with three bullets in his arm. MacDonnell, by the same volley, had both his arms broken, but he was soon afterwards despatched. Gallagher was then discovered, and they were about to kill him, only Fitzgerald ordered him to be taken to his house.

News was sent to Castlebar of what had taken place, and Fitzgerald calmly awaited the result. Fully aware of the dangerous character they had to deal with, the authorities sent a large body, both of regular troops, and volunteers, to Turlough, and these were accompanied by an immense mob of people. What happened is best related in the following graphic account:

‘Brecknock was for remaining, as with the calmness of conscious innocence, and boldly demanding a warrant against Gallagher and others. This opinion, however, did not agree with Fitzgerald’s own, who justly dreaded the fury of the volunteers and the populace, with whom MacDonnell had been so popular. Neither did it coincide with that of the Rev. Mr. Henry, the Presbyterian clergyman of Turlough, who had been latterly a resident in the house, and was now wringing his hands in wild alarm for what had occurred. This gentleman’s horse was at the door, and he strongly urged George Robert to mount, and ride for his life out of the country altogether, till the powerful intercession he could command might be made for him. In compliance with this advice, which entirely coincided with his own opinion, it is stated that he made several attempts to mount; but that, splendid horseman as he was, whether through nervous excitement, guilty terror, or the restiveness of the animal, he was unable to attain the saddle, and, in consequence, obliged to fly into the house again, as the military were announced to be approaching near. It is also generally asserted that the Rev. Mr. Ellison, who headed the soldiers, sent them on to Gurth-na-fullagh, without halting them at Turlough, where he himself stopped.

‘Were this circumstance even true, however, Fitzgerald gained but a short respite by it, as the volunteers, with many of the populace, came furiously up immediately after; and, some of them being placed about the house, the remainder entered to search and pillage it. Brecknock and Fulton were immediately captured, but, after ransacking every corner and crevice more than once without finding him, the volunteers were beginning to think that Fitzgerald must have effected his escape before their arrival, when one of them, forcing open a clothes-chest in a lower apartment, discovered him among a heap of bed-clothes in his place of concealment.

‘“What do you want, you ruffian?” he said, on finding himself detected.

‘“To dhrag ye, like a dog’s head, to a bonfire,” replied another volunteer, named Morran, a powerful man, who seized him at the same time by the breast, and drew him forth by main force.
