O'Dogherty's castle of Burt on Lough Swilly, where Lady O'Dogherty, Lord Gormanston's sister, was living. He told O'Dogherty afterwards that he only went on a friendly visit, but to Chichester he said that he meant to seize the castle had he not found it well defended. [Sidenote: Paulet's violent behaviour.] O'Dogherty remonstrated in a temperate letter and subscribed himself 'your loving friend,' but Paulet retorted that he was a traitor and that he left him to a provost-marshal and a halter. Three weeks later O'Dogherty went to Dublin, and protested his loyalty; but he was on good terms with O'Cahan, whose actions were also suspicious, and Chichester hardly knew what to think. Sir Cahir was at last suffered to depart after entering into a recognisance, himself in 1,000_l._ with Lord Gormanston and Sir Thomas Fitzwilliam in 500 marks each, to appear at all times upon twenty days' notice in writing, and not to leave Ireland without licence before Easter 1609. About the close of the year 1607, Sir Cahir was foreman of the Grand Jury who found a true bill for treason against Tyrone, Tyrconnel, and their chief adherents.[46] [Sidenote: Paulet insults O'Dogherty,] In February 1608 O'Dogherty wrote to the Prince of Wales protesting his fidelity, and asking to be made one of the gentlemen of his privy chamber. On April 18, the very day on which he plunged into rebellion, an order was sent by the English Government to restore the island of Inch, and all other lands withheld from Sir Cahir, excepting only the fort of Culmore, which stood at the mouth of the Foyle, and thirty acres of land with it.
