The Army of the North was a military force raised in Ireland during 1689 as part of the Williamite War.
[1] It was made up of Protestants from Ulster, who declared their opposition to the rule of the Catholic James II and endorsed the Glorious Revolution.
The force was raised in opposition to the Royal Irish Army which had been purged of Protestant officers and men and replaced by Catholics.
[3] In response the authorities in Dublin despatched troops under Richard Hamilton northwards to put down the rebellion.
After the Army suffered major defeats at the Break of Dromore and the Battle of Cladyford it largely dispersed.
