The new chief at once took up the thread of his father's policy by invading Connaught, and at the same time making loyal professions to Grey. He had, he wrote, been tempted to rebellion by all the disaffected lords in the South and West, but was determined to take no advice but that of the King and his Deputy. As soon as he heard of Hugh O'Donnell's death, Grey at once repaired to the borders of Ulster. The galleys of O'Neill and his Scotch allies had threatened a fortified settlement at Ardglass on the coast of Down, and the Deputy burned to invade Tyrone; but the Council dissuaded him, and the receipt of Manus O'Donnell's letter gave hopes of settling the North by peaceful means. Some thought Grey too fond of making aimless raids, and Alen made some sensible remarks on the subject. 'I would not,' he wrote to St. Leger, 'have the Deputy representing the King's Majesty's person and estate be a common skurrer for every light matter; but, when he should begin a war, begin it upon a just good ground, and when it were so begun, to be so profoundly executed, that all other should take example thereby.' But the King thought only of increasing the revenue and diminishing the army.[191] [Sidenote: Grey is baffled by the O'Connors.] Grey had been sanguine enough to believe that his work in Offaly would be lasting, but, as Henry had partly foreseen, O'Connor's return had undone it all. Cahir was a fugitive, and the floods protected Offaly, where the corn had been safely garnered in. At last the waters subsided, and Grey reached Brackland by the old road through Westmeath. O'Connor escaped into O'Doyne's country, the modern barony of Tinnahinch, which Grey and Richard Butler proceeded to ravage. While thus employed the scattered troops were surprised by O'Connor, and some were killed. The Lord Deputy was just able to destroy or carry away the corn stored at Geashill, and to return to Dublin without having seen the enemy. To gain time till the season of long days came round again, Grey gave a safe-conduct to O'Connor, who proposed to visit Dublin. 'But shortly herein to conclude,' as Brabazon puts it, 'the said traitor and his brother Cahir fell to agreement and concord, so that at this presents they both remain in Offaly.' St. Leger, who had a cooler temper than Grey, saw the impossibility of subduing even a single clan by desultory hostings. 'The country,' he said, 'is much easier won than kept.' To overrun Offaly was a small thing, but it could only be united to the Pale by the costly expedient of fixed garrisons. O'Connor had got back his son, and indeed neither he nor any Irishman had much regard for promises or for the fate of hostages.[192] [Sidenote: He continues to attack them.]
