Carew launched an offensive against Fitzthomas's forces. The English routed Fitzthomas' forces at Aherlow and in November, Carew reported to London that he had, over the summer, killed 1,200 'rebels' and taken the surrenders of over 10,000. Carew also weakened Florence MacCarthy's position by recruiting a rival MacCarthy chieftain, Donal, to English service. In June 1601, James Fitzthomas was captured by the English forces. Shortly afterwards, Carew had Florence MacCarthy arrested after summoning him for negotiations. Both Fitzthomas and MacCarthy were held captive in the Tower of London, where Fitzthomas eventually died. Most of the rest of the local lords submitted, once the principal native leaders had been arrested. O'Neill's mercenaries had been expelled from the province. Battle of Kinsale and the collapse of the rebellion Mountjoy managed to penetrate the interior of Ulster by seaborne landings at Derry (then belonging to County Coleraine) under Henry Docwra and Carrickfergus under Arthur Chichester. Dowcra and Chichester, helped by Niall Garve O'Donnell, a rival of Hugh Roe, devastated the countryside in an effort to provoke a famine and killed the civilian population at random. Their military assumption was that without crops and people or cattle, the rebels could neither feed themselves nor raise new fighters. This attrition quickly began to bite, and it also meant that the Ulster chiefs were tied down in Ulster to defend their own territories. Although O'Neill managed to repulse another land offensive by Mountjoy at the Battle of Moyry Pass near Newry in 1600, his position was becoming desperate. In 1601, the long promised Spanish finally arrived in the form of 3,500 soldiers at Kinsale, Cork, virtually the southern tip of Ireland. Mountjoy immediately besieged them with 7,000 men. O'Neill, O'Donnell, and their allies marched their armies south to sandwich Mountjoy, whose men were starving and wracked by disease, between them and the Spaniards. During the march south, O'Neill devastated the lands of those who would not support him. The English force might have been destroyed by hunger and sickness but the issue was decided in their favour at the Battle of Kinsale. On the 5/6 January 1602, O'Donnell, against the wishes and advice of O'Neill, took the decision to attack the English. Forming up for a surprise attack, the Irish chiefs were themselves surprised by a cavalry charge, resulting in a rout of the Irish forces. The Spanish in Kinsale surrendered after their allies' defeat. The
