The Battle

History & Significance

The most celebrated battle in Irish history — celebrated by Ulster Protestants to this day on 12 July (by the Gregorian calendar). William III personally led his army across the River Boyne against James II. Though not a catastrophic defeat, James's flight to France ("Séamas an Chaca" — James the Shit) broke Jacobite morale. The battle confirmed William's control of Ireland east of the Shannon and is the defining cultural memory of Protestant Ireland.

Casualties & Losses

c.2,000 Jacobites killed; c.500 Williamites
