Raised by the Catholic Randal MacDonald, Earl of Antrim, who at first attempted to remain neutral during the Irish rebellion. The regiment consisted of 7 companies under Archibald Stewart, Antrim’s factor. 5 companies were Protestant and 2 Catholic, led by Alasdair MacColla and Turlough Og O’Cahan.

At Portnaw in January 1642 MacColla led the two Catholic companies to surprise and defeat the Protestant companies under Stewart, before joining the Irish rebels. Stewart led the remains to Coleraine, apart from Capt Kennedy’s company who were besieged at Clough Castle. At Coleraine Stewart was besieged by MacColla and the O’Cahans until relieved in May(?) by Sir William Stewart’s Laggan Army. Archibald Stewart led a foray in February that was ambushed at Laney near Ballymoney by MacColla and defeated by Mac Colla’s ‘Highland charge’.
