The Battle of Moiry Pass was a military engagement between a Scots-Irish army commanded by Edward Bruce, brother of Robert Bruce, king of Scotland and a Hiberno-Norman force. It took place during the First War of Scottish Independence and more precisely the Irish Bruce Wars. Edward Bruce attacked a garrison of soldiers from the Lordship of Ireland, as part of his attempt to revive the High Kingship of Ireland. Bruce considered the battle a great success but his campaign would ultimately fail.
