The Battle of Skerries, also named the Battle of Ardscull, a battle in the Bruce campaign in Ireland and part of the First War of Scottish Independence, is fought on January 26, 1316, resulting in a Scottish victory. It is part of the Irish campaign of Edward Bruce, brother of Robert the Bruce, King of Scotland. The site of the battle is Skerries near Ardscull in County Kildare.

Edward Bruce, Earl of Carrick, lands in Ireland in May 1315 and is proclaimed king of the island in June. Bruce continues on his march south, when on January 26, 1316, the Scottish army is advancing from Castledermot when it encounters the English. The Hiberno-Norman forces, summoned by the justiciar of Ireland, consists of men such as John FitzThomas FitzGerald, Maurice FitzThomas FitzGerald, Thomas FitzJohn FitzGerald, John and Arnold Poer, Maurice de Rocheford and Miles and David de la Roche. Though these forces heavily outnumber those of Bruce, internal strife breaks out in the Anglo-Irish ranks, a fact that Bruce can take advantage of. Though suffering heavy losses, the Scots hold the battlefield, effectively winning the battle.

The official English account of the battle blames unfortunate terrain and bad luck for the government forces’ loss, not an entirely convincing explanation. The same account also claims that the Scots lost many of their greatest men, while their opponents only lost one man.

After the battle the Scots plunder the nearby town of Athy before withdrawing to Leix, while the Anglo-Irish forces keep them under surveillance from nearby Castledermot, while their leader withdraws to Dublin. Here John Hotham, the king’s envoy to Ireland, makes a great effort to ensure the loyalty of the Irish nobles. By May, however, Bruce has returned to his safe base in Ulster, while Hotham has returned to his new position in England as Bishop of Ely.
