James Dillon (officer)

Sir James Dillon (born c1600; died after 1669) was an officer in the armies of the Irish Confederate Catholic during the Irish Confederate Wars (1641-53) and a Member of the Parliament of Ireland. He was likely born at Kilfaughny, Athlone and lived in the vicinity.

Biography
Dillon was a captain in Wentworth's 'new army', which was recruited in Ireland to help put down a rebellion against King Charles I in Scotland. This force was disbanded after an outcry against arming Irish Catholics in the Parliaments of England and Scotland. When it disbanded in 1641 Dillon was authorised, with his own £1,000 (2009: £0), to raise a regiment of the demobbed soldiers for the Spanish Army. However, this plan was interrupted by the outbreak of a Catholic rebellion in Ireland in October 1641. The brewing conflict lost him his investment and later that year he joined the revolt of his fellow Catholic gentry.

Dillon is alleged to have conspired with Lord Maguire before the rebellion; he proposed seizing Dublin Castle but according to some accounts, the Earl of Ormonde, commander-in-chief, talked him out of it. However, the claim that Dillon and Ormonde (who was a Protestant) knew of the planned rebellion in adcance has never been proved.

After the outbreak of the rebellion in 1641 Dillon joined the rebels and participated in the alternative government the Catholics set up at Kilkenny in March 1642, under the name, the Confederate Catholics of Ireland. He was appointed governor of Longford and Westmeath by the Confederate regime.

Dillon is recorded as a dove within the confederacy - favouring a speedy reconciliation with Charles I of England and Irish Catholic participation in the English Civil War on the royalist side. The question of whether to do this, or whether to achieve Catholic aims in Ireland by military force, against all the English factions, was a source of major division among the Confederates. Dillon was the dominant military leader in west Leinster and, as an infantry colonel, recruited and equipped over 1,000 men.

Throughout 1642, Roger Jones, 1st Viscount Ranelagh held him off in Athlone. Ranelagh held the castle, west of the Shannon. Ormonde, by this time commander of the English royalist forces in Ireland, relieved the town without difficulty. In January 1643, at Rathconnell near Mullingar, Dillon attacked a second relief force as it returned to Dublin with the remnants of Ranelagh's garrison.

His regiment assisted Thomas Preston, 1st Viscount Tara in capturing Roscommon and Jamestown.

In 1647 his regiment was destroyed, along with much of the Confederate's Leinster army, at the Battle of Dungan's Hill, when they were defeatd by an English Parliamentarian army which by that time held Dublin.

Dillon fought against the Cromwellian conquest of Ireland from 1649-51, when the English Parliament, victorious in the English Civil War, launched a renewed invasion of Ireland. In 1651 Dillon surrendered Athlone to the parliamentarians.
