Naturally his father did not take this quietly, and possession was not held peacefully. There were many collisions; and old Fitzgerald indicted his son for having headed a riotous mob, one of whom, he alleged, had, at his son’s instigation, attempted to take away his life, by firing a loaded musket at him. The charge could not be sufficiently proved, and Fitzgerald was acquitted.

He now turned his attention towards improving his estate, and imported some Scotch Presbyterians, a sober and industrious set of men, to whom he gave five hundred pounds towards building a meeting-house, and settled fifty pounds per annum on their minister; but his father’s party were always annoying him, and, in consequence, he refused to give maintenance to his father, who, thereupon, had recourse to the law-courts in Dublin to compel him so to do; and a writ was issued empowering the father to secure the body of his son until a maintenance was granted him. It would have been perfectly useless to have served the writ upon him at Turlough: it is probable no man could have been found bold enough to attempt it. So they waited until the next assizes at Balinrobe; and then, when they thought they had him safe in the grand jury room, they made application to the judge to arrest him there. Leave was granted, but Fitzgerald got wind of it, and when they went to capture him, lo! he was not to be found.

He evidently thought two could play at that game, and he determined to get the old man into his power. In those days, in that part of Ireland, law was not much regarded, especially by men of Fighting Fitzgerald’s stamp; and he speedily put his plan into execution. As his father was going from Balinrobe to Dublin, he was waylaid by his son and a party of armed men, and carried off vi et armis to George Robert’s house at Turlough.

This open violation of the law could not be submitted to tamely, and his younger brother went to Dublin, and stated his case before the judges, who granted him a writ of habeas corpus. But no one would serve that at Turlough, so they waited, as of aforetime, until he was at the grand jury room, and, leave having been given, his brother, who was bigger and stronger than he, went in, and, literally collaring him, dragged him out, spite of all his protests that he was a grand jury man, and could not be touched while in the exercise of his functions. He was at once put on his trial, and the grand jury found a true bill against him, unanimously: nay, more, they publicly addressed the judge in court, expressing their abhorrence of the charge made against Fitzgerald. After the finding of a true bill, his trial at once took place, in despite of all efforts to postpone it to the next assizes, and it lasted from nine in the morning until nearly twelve at night, when, the judge having summed up, the jury found him guilty, and he was fined £1,000, to be imprisoned for three years, and until he should pay the fine.

What happens next in this man’s extraordinary career is almost difficult to believe, and shows the lawless state of the country. Fitzgerald was committed to Castlebar prison, but he seems to have been at large therein, for, four days after his committal, he calmly walked out of gaol, armed with a brace of pistols, and scattering a bag of silver to be scrambled for by the gaolers. The doors were all open, a horse was in readiness, and off he went, tantivy, for Turlough, where he was welcomed by his people with volleys of small arms and discharge of cannon. These latter Fitzgerald had procured from a ship, under the pretext that they would be useful for his volunteers, of which he was the colonel. These he mounted as a regular battery, and it was garrisoned in a perfectly military manner by his volunteers.

But an escape from prison was, by the law of Ireland, deemed a capital felony, and the sheriff of the county issued proclamations and rewards for his apprehension, at which Fitzgerald only laughed, for he could rely on his men, and he had his father still in his custody, as the old man did not go away when his son was, as he thought, safely imprisoned. He was some fifteen months at large before the majesty of the law asserted itself. Then a little army, consisting of three companies of foot, a troop of horse, and a battery of artillery, under the command of Major Longford, was sent to reduce this rebel. But, when they got to Rockfield, they found the cannon spiked, and the birds flown to Killala, whither they were followed by Charles Lionel, at the head of the Castlebar volunteers. But many people gathered round Fitzgerald, and he soon had a party which was too strong for them to attack. But, a large reinforcement arriving, he had to flee, and, with his father, and two or three attendants, he put to sea in an open boat, landing on a small island in the bay of Sligo.

Here his father offered him terms, that if he would give him £3,000 to clear off his debts, and pay him a small annuity, he would give him up the estate, and completely exonerate him of all blame in his capture and detention. To these terms Fitzgerald assented, and set off with his father through bye, and unfrequented roads to Dublin. But no sooner had the old man got into his old lodging, than he refused to ratify his bargain, and set his son at defiance.

Fitzgerald, although there was a reward out of £300 for his apprehension, took no pains to conceal himself, and, consequently, had not been long in Dublin, before Town-Major Hall heard of his whereabouts, and, taking twelve soldiers of the Castle guard with him, arrested Fitzgerald, and safely lodged him in the Castle, where he was confined in the officer’s room; and there he abode till the general election, when, through the influence of his powerful friends, he was released. During his incarceration he wrote an appeal to the public on his case, although some say the author was one Timothy Brecknock, a somewhat unscrupulous lawyer whom Fitzgerald employed.

The first use he made of his newly-acquired liberty was to revenge himself on a man who he fancied had done him some grievous injury, a somewhat eccentric gentleman named Dick Martin, and he determined to insult him in the most public manner. He met him at the theatre, struck him with his cane, calling him the bully of the Altamonts, and walked away. Of course, in those days a gentleman so insulted could but do one thing, and that was to send a challenge—and Martin did send Fitzgerald one by the hand of a cousin of the latter, a Mr. Lyster. While he was explaining the object of his visit, Fitzgerald rang the bell, and requested his footman to bring him his cudgel ‘with the green ribbon.’ This being brought, he walked up to his cousin, and ferociously asked how he dared to deliver such a message to him: then, not waiting for a reply, he belaboured him most unmercifully, with such violence indeed, as to break a diamond ring from off his finger. When he considered him sufficiently punished, he made him pick up his ring and present it to him—but he did not keep it, he wrapped it up in paper, and returned it, telling his cousin not to go about swearing that he had robbed him of it.

Martin could get no satisfaction out of Fitzgerald in Dublin, the object of the latter being to let his adversary have the reputation of being an insulted man. But, afterwards, they met at Castlebar, and a meeting was arranged. Martin was hit, and his bullet struck Fitzgerald, but glanced off: according to some it hit a button; according to others, Fitzgerald was plastroné, or armoured.
