Before he had time to begin in the south, Perrot got wind of raids into the northern province of Ulster by the Highland clans of Maclean and MacDonnell at the invitation of Sorley Boy MacDonnell. He marched a contingent of the Royal Irish Army beyond the Pale to confront the invaders, but Sorley Boy escaped by crossing over to Scotland, only to return later with reinforcements. Elizabeth roundly abused her deputy for launching such an unadvised campaign, but by 1586 Perrot had brought Sorley Boy to a mutually beneficial submission. At about this time he also sanctioned the kidnap of Hugh Roe O'Donnell (lured to a wine tasting on a merchant ship and then sealed in a cabin and brought to Dublin), a move which gave the crown some leverage in western Ulster. Perrot's northern strategy also secured the submission of Hugh Maguire, Lord of Fermanagh.
