Carrickfergus and Edward Bruce
In 1234 Carrickfergus is mentioned as one of the haven towns of Ulster; but from that period till shortly after the commencement of the 14th century, little of its history is known. The De Lacys, again becoming obnoxious to the English monarch, and the Lord-Justice Mortimer being sent against them with a considerable force, they made their escape into Scotland, and invited Edward Bruce, the brother of the Scottish monarch, to invade the country, and become their king. Accordingly, in 1315, Bruce embarked 6000 men at Ayr, and, accompanied by the De Lacys and several of the Scottish nobility, landed at Wolderfirth, now Olderfleet, where, being joined by numbers of the Irish chieftains, he routed Richard de Burgo, now Earl of Ulster, who had been sent against him; and having slain several of the English nobles and taken many of them prisoners, advanced to lay siege to the castle of this place. During the siege, Thomas, Lord Mandeville, who commanded the garrison, made a sally on the assailants, whom he repulsed at the first onset; but, being recognised by the richness of his armour, he was felled to the ground by the blow of a battle-axe and instantly killed.
The garrison, disheartened by the loss of their commander, agreed to surrender the castle within a limited time, and on the appointed day, 30 of the Scottish forces advancing to take possession, were seized as prisoners, the garrison declaring that they would defend the place to the last; but for want of provisions they were soon obliged to surrender. Bruce, having secured Carrickfergus, advanced to Dublin, and arrived at Castleknock, within four miles of the city; but finding the citizens prepared for his reception, he entered the county of Kildare, and advanced towards Limerick, laying waste the country with fire and sword; on his retreating towards the north, he was attacked near Dundalk by Sir John Bermingham, who defeated the Scottish forces and killed their leader. King Robert Bruce arrived soon after with a strong reinforcement, but on learning the fate of his brother, returned to his own dominions, and thus terminated an enterprise which had thrown the country into a state of unprecedented desolation.
