27 November 1641
The battle
The Irish Rebellion of 1641 began with uprisings in Ulster. Forces under Sir Phelim O'Neill moved south toward Drogheda to lay siege and capture the grain stores and seaport. At Julianstown bridge over the River Nanny, they met a government force sent to defend against them. The insurgents broke the cavalry in a chaotic engagement; the government troops retreated in disorder. In military terms, it was a skirmish. In political terms, it changed everything.
Rebellion spreads
The chain reaction
The victory at Julianstown became news — in a century before newspapers, that meant rumour and report. The insurgents had beaten English soldiers. The rebellion that started in Ulster suddenly looked possible everywhere else in Ireland. Within weeks, uprisings had spread through Leinster, Munster, and Connacht. The bridge became a turning point more by accident of timing than design.
Meath and Louth
The River Nanny
The River Nanny marks the boundary between County Meath and County Louth. Julianstown sits on the bridge, belonging to both counties and to neither. In 1641, that made it a natural place for armies to meet — it was where counties disagreed about who should defend the river.
