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.
