Before leaving Derry Phelim Reagh, who thought the place untenable by a small force, deliberately burned Bishop Montgomery's library in sight of his men. O'Sullivan says there were '2,000 heretical books,' and that the bishop vainly offered a hundred pounds ransom for his collection. Having set fire to the buildings and to two corn ships which lay near, Phelim removed to Culmore, taking some guns with him in two boats and throwing the rest into the sea. Doe Castle on Sheep Haven was also surprised, and Captain Henry Vaughan taken prisoner. Captain John Vaughan abandoned Dunalong and fled with his men to Lifford, and a few Scotch settlers at Strabane did the same. There O'Dogherty's successes ended. Sir Richard Hansard, who never ceased to take the precautions which Paulet neglected, easily maintained himself at Lifford, and help was not long in coming. At the beginning of May Chichester sent all his available forces to Ulster. The officers in charge were Sir Richard Wingfield, Marshal of the army since 1600, and Sir Oliver Lambert, then more hated and feared than any English soldier. Sir Thomas Ridgeway, an energetic man who had succeeded Carey as vice-treasurer, accompanied them without Chichester's knowledge. After inspecting the garrisons about Lough Neagh and the Blackwater, and warning them to be on their guard, Wingfield and his colleagues reached Derry on May 20. They found earthworks, walls and chimneys not much damaged, but everything that would burn had been reduced to ashes, except the wooden roof of the cathedral. Ridgeway was in doubt whether they had found this roof too high to set fire to, or whether they spared it out of respect to St. Columba, 'the patron of that place, and whose name they use as their word of privity and distinction in all their wicked and treacherous attempts.' According to the terms of the recognisance in which he was bound, Chichester's letter summoning O'Dogherty to appear before him was publicly read by Ridgeway at 'the half-burned house of Master Babington' in Derry, and at Sir Cahir's own castle of Ellagh not far off. Cabins were run up for the inhabitants of Derry, who had already returned to their homes, and enough cows and sheep to secure them against starvation were driven in from O'Dogherty's country. Phelim Reagh declared that he would die in defence of Culmore, but thought it more prudent to set the place on fire and to escape by water. The fort was quickly refitted and garrisoned. Parties were sent to scour the country as far as Dunaff and Malin Head, and Inishowen was completely cleared, 2,000 cows, 2,000 or 3,000 sheep and 300 or 400 horses were driven in, and Buncrana was burned 'as well from anger as for example's sake.' Armed resistance there was practically none. O'Dogherty had withdrawn into the territory of the MacSwineys west of Lough Swilly, and thither did Ridgeway and his colleagues pursue him. Even among the woods of Glenveagh he was
