Charles Blount, 8th Baron Mountjoy, English nobleman and soldier, becomes Lord Deputy of Ireland under Queen Elizabeth I on January 21, 1600.

Blount is born in 1563, the second son of James, 6th Baron Mountjoy, and Catherine, only daughter of Sir Thomas Legh. He is among the most distinguished of the family, succeeding as 8th Baron Mountjoy on the death in 1594 of his unmarried elder brother William, 7th Baron Mountjoy. The good fortune of his youthful and handsome looks find favour with Queen Elizabeth I which arouses the jealousy of Robert Devereux, 2nd Earl of Essex, leading to a duel between the two courtiers, who later become close friends.

Blount is returned to the House of Commons as MP for St. Ives, Cornwall in 1584 and for Bere Alston in 1586 and 1593, before entering the House of Lords in 1594. Between 1586 and 1598, he spends most of his time on the Continent, serving in the Netherlands and Brittany. He joins Lord Essex and Sir Walter Raleigh in their expedition to the Azores in 1597, along with his distant cousin, Sir Christopher Blount.

The downfall of Lord Essex does not damage Blount’s career. After the failure of his rebellion, Essex shocks many by denouncing his sister Penelope, who is Blount’s mistress, as a traitor, which inevitably raises the question of his own possible involvement. But the Crown, anxious to retain Blount’s services, and also to show as much leniency as possible to the defeated rebels, simply ignore the accusation.

On February 24, 1600, Blount lands in Ireland as Lord Deputy following Lord Essex and in the ensuing years brings the Nine Years’ War to an end. The leader of the rebellion, Hugh O’Neill, Earl of Tyrone, writes about Blount’s “refined manners” that he would lose a whole season of campaigning “while waiting until breakfast is prepared to his mind!” Despite this, Blount proves that he is quite qualified to pursue the war.

In early 1600, Blount dispatches Sir Henry Docwra with an army of 4,200 troops to land at Culmore to erect a fortress commanding the shores of Lough Foyle in the northwest of Ulster. To prevent Hugh O’Neill from sending a strong force to repulse Dowcra’s forces, Blount advances in force from Dublin to Newry causing O’Neill to fear a southern advance into Tyrone.

Blount aims to avoid the mistakes of previous Lords-Deputy. After the Battle of Moyry Pass, he has it cleared, and a garrison is established there. It had long been a problem for English forces advancing into Ulster from the south. He also establishes posts with garrisons at Mountnorris and Armagh.

On July 13, 1601, Blount and his army along with Turlough McHenry O’Neill of the Fews who had recently switched to the English side in the war, have a stand-off with Hugh O’Neill’s forces at the River Blackwater. After a few shots in vain from either side, O’Neill’s forces withdraw, and Blount sends his forces to occupy the ruined Blackwater fort destroyed by O’Neill in 1595. Later O’Neill’s forces attack Blount’s camp before withdrawing. In response, the Lord-Deputy sends his forces across the river where they find strong artificially fortified fords, which would have held out against the English.

By July 15, 1601, the Lord-Deputy has secured the surrender of O’Neill’s ally Hugh Magennis. That month, he has a new fort near the old Blackwater fort erected.

Blount reports to the council in England that O’Neill is determined to prevent his forces from advancing into Tyrone and toward Dungannon. As such, he initiates a policy of burning large quantities of corn to induce a famine to drive the rebels out of their strongholds.

Blount sets about trying to entice Hugh’s forces to come out and attack by fetching some materials for the new fort from the Tyrone side of the river as well as burning more corn. Further skirmishes between Blount and O’Neill’s forces ensue during the summer of 1601.

Spanish forces land in Munster in August 1601, forcing Blount to send his forces southward leaving O’Neill remaining in his unbroken heartland of Tyrone. The Spanish arrival culminates in the Siege of Kinsale that December, which sees a major defeat of the rebels and their allies.

O’Neill during this time has also moved south to assist some of his allies, however, after some serious defeats at the hands of the forces of Richard Burke, 4th Earl of Clanricarde of Connacht, he is in no place to offer any effective resistance once Blount marches once more to Tyrone in the summer of 1602.

Blount advances to the location he found the previous summer at the River Blackwater, which commands safe and secure passage into Tyrone, previously inaccessible, and sets about erecting a new fort. Having observed this, O’Neill burns his capital at Dungannon and flees to his last refuge in Glenconkeyne.

Advancing northward through Tyrone, Blount erects a fort in the townland of Magheralamfield, afterward known as Mountjoy Castle. He also christens the new fort at the Blackwater Charlemont Fort after himself.

Once in Tyrone, Blount carries out a campaign of devastation throughout it resulting in the mass hunting of rebels, spoiling of corn, the burning of houses and the killing of churls so as to force the submission of O’Neill and his remaining allies. Most symbolically, Blount has the inauguration site of the O’Neill’s at Tullyhogue Fort destroyed.

On March 30, 1603, six days after the death of Elizabeth and the accession of James I, O’Neill makes peace with Blount, signing the Treaty of Mellifont. Blount continues in office with the more distinguished title of Lord-Lieutenant. He declares amnesty for the rebels and grants them honourable terms, which causes some severe criticism from England. He shows similar moderation in putting down the abortive risings in Cork, Waterford and Wexford, where the aldermen, apparently with some vague idea of gaining greater toleration for Roman Catholics, refuse to proclaim the new King. In Cork, three insurgents are hanged after a summary trial, but the rest are acquitted or pardoned.

As part of the Plantation of Ulster, the majority of the barony of Loughinsholin is detached from County Tyrone and made part of the newly created County Londonderry. The rest of Loughinsholin along with the northern parts of Dungannon barony are merged to create the short-lived barony of Mountjoy. It is later amalgamated with the barony of Dungannon.

On his return to England, Blount serves as one of Sir Walter Raleigh’s judges in 1603, and in the same year King James I appoints him Master-General of the Ordnance as well as creating him Earl of Devonshire, granting him extensive estates. He is one of the founder members of the Spanish Company re-founded by royal charter in 1605.

Toward the end of Blount’s life, on December 26, 1605, at Wanstead House near London, in a ceremony conducted by his chaplain William Laud, afterward Archbishop of Canterbury, he marries his long-time mistress Lady Penelope, formerly wife of Robert Rich, 3rd Baron Rich (later 1st Earl of Warwick) and sister of Robert Devereux, 2nd Earl of Essex.

Blount leaves no legitimate children, and so his hereditary titles become extinct at his death on April 3, 1606, at Savoy House, London.
