On 26 May 1315 Edward and his fleet (and more than 5,000 men) landed on the Irish coast at points at and between Olderfleet Castle at Larne, and Glendrum. His brother had sailed from Tarbert for the Western Isles with his son-in-law Walter Stewart, to subjugate them till ""all the isles, great and small, were brought to his will."" Edward faced by an army led by vassals and confederates of the Earl of Ulster, the de Mandevilles, Bissets of the Glens, Logans, and Savages, as well as their Irish allies, overall led by Sir Thomas de Mandeville. However they were defeated in battle by the Scots under Thomas Randolph, Earl of Moray. Subsequently, the Scots managed to take the town, though not the castle, of Carrickfergus.
