29 November 1641: Battle of Julianstown/ Baile Iúiliáin in County Meath was fought on this day. Julianstown is situated on the River Nanny, which flows into the sea at Laytown about 3 km away. It was along this way that an English relief force was dispatched by the Lords Justice Borlase and Parsons to help relieve the town of Drogheda, which was in danger of encirclement by the Irish insurgents of Sir Phelim O’Neill.
He directed a force led by Colonel Rory O'More / Ruairí Óg Ó Mórdha to prevent this column from ever reaching Drogheda and O’More kept close to the main road north from Dublin to enable him to strike at a moment of his own choosing. As luck would have it the weather this day was cold and foggy and the English, even though warned beforehand by Lord Fingal that they were in immediate danger, stumbled into an ambush. O’More waited until the moment was ripe and then the Irish warriors uttered a great shout of their war cries and rushed out of the mists to fall upon the hapless column cutting them to pieces. Some 600 of the enemy were left dead on the road and surrounding fields while the few survivors fled back in the direction they came.
The defeat of the troops sent from Dublin was a powerful factor in influencing the Old English of Meath to throw in their lot with their fellow co religionists to halt any further encroachments upon their Civil and Religious Liberties by the English Protestants.
