Sir Con’s downfall came about because, being minded to import wine into the harbour at Carrickfergus, the garrison there looted it on the way to his cellars, and his servant killed one of the soldiers in a hasty affray in 1602. The chief and his retainers had been in the pay and service of Queen Elizabeth since 1600, yet this scuffle Chichester dubbed “treason.” Instead of punishing the thieves he attacked the owner of the wine, and Sir Con’s life and lands were put in jeopardy. He was arrested, thrust into a cell in Carrickfergus Castle, and tried as a rebel by “office of inquest” before the Provost-Marshal. There had been no Provost-Marshal at Carrickfergus in Elizabeth’s reign; and, in order to do service on Sir Con, Chichester got leave, on the 30th August, 1603, to appoint one. He and the Ulster Earls were then in London, and before Con could be executed he escaped from the Castle. A Scotch laird, Sir Hugh Montgomery, helped him to fly, and had him ferried across the narrow strait between Carrickfergus and Scotland. The Laird was brother to the new Court Chaplain under James I., the Rev. George Montgomery. To London he took Sir Con to see the reverend favourite and secure a Stuart pardon. O’Neill promised him a large fee, no less than half his estate, as the price of “forgiveness.” When they arrived at Court the suppliants encountered the ex-spy, Sir James Fullerton, brimful of craft and watchful of chances. He was the old comrade of Hamilton, and contrived a turn for him out of Sir Con’s distress. His influence was such that the King only granted the “pardon” on condition that the chief’s bargain with Montgomery should be recast and a third of his estate given to Hamilton. O’Neill was kept dangling about the Court for over a year before this composition was arrived at. Thus the chief was shorn of two-thirds of his lands instead of half, as the price of “mercy.” To temper the loss to Montgomery the King promised to throw in as many abbeys and monasteries as would make it good, but Sir Con had to submit to the condition that the new Patent should be made out in Hamilton’s name and accept his promise to assign a third to himself and Montgomery. Such was Fullerton’s fealty to his brother-spy. At his death Fullerton was honoured with a grave in Westminster Abbey.
