The Battle of Clontibret is fought in County Monaghan in May 1595 during the Nine Years’ War, between the crown forces of England‘s Queen Elizabeth I and the Irish army of Hugh O’Neill, Earl of Tyrone. It ends in victory for Tyrone on May 27, 1595, and is the first severe setback suffered by the English during the war.

The Nine Years War begins with a conflict over English efforts to maintain a string of garrisons along the southern border of Tyrone’s territory in Ulster. The Irish leader promptly besieges the English garrison at Monaghan Castle, and Sir Henry Bagenal, commander of the English forces, marches out to its relief on May 25 from Dundalk, via Newry. His army is made up of 1,750 troops, including some veterans and certain companies newly arrived from the Spanish campaign in Brittany, but there are many recruits in the ranks. Bagenal’s men are predominantly infantry, armed with muskets and pikes. There is also a small number of horsemen raised in the Pale.

The Battle of Clontibret is essentially a two day running battle, as Bagenal’s column is ambushed on its way to and from the castle at Monaghan town. The Irish fight sharply along the roads about Crossdall, around 4 miles from Monaghan, firing on the English column with calivers from the surrounding woodland. With the loss of 12 dead and 30 wounded the English reach the castle, which is re-supplied and reinforced with one company. Bagenal has misgivings about his supply of powder and lead, much of which had been used on the way, and can afford little for the garrison before he starts back.

Two days later, on May 27, Bagenal sets out for Newry in a column, but by another route, past the townland of Clontibret. The route lay through drumlin country, which abounds with hills, bogs and woods, making it ideal for an ambush. The column comes under fire from the outset, and then falls into a major ambush at a pass near Clontibret. Tyrone’s army, about 4,000 strong, consists of contingents from the O’Neill, MacMahon and Maguire clans, as well as Scottish mercenaries. The Irish also deploy a greatly enlarged force of cavalry and caliver-men. To Bagenal’s puzzlement, the caliver-men are turned out in red coats and acquitted themselves with expertise. Fire from the flanks is heavy, and many English troops are killed or wounded while the Irish cavalry plays around the fringes. Tyrone himself is almost killed in hand-to-hand combat with a Palesman named Seagrave, who leads a cavalry charge on the Irish position. Seagrave has his arm chopped off by Tyrone’s standard bearer O’Cahan, and is killed by Tyrone with a dagger thrust to the groin. Bagenal’s column is slowed to a crawl and, as night falls in the wilderness, the commander calls his men to a halt and camps at the hilltop of Ballymacowen. It seems that hundreds are missing, and there is fear that the Irish will renew the attack under cover of darkness. There is no further attack and, a little after first light, reinforcements from Newry arrive to relieve the column.

According to intelligence received in the days following, Tyrone’s failure to follow up is caused by a lack of powder, ironic given the state of Bagenal’s own supplies. The overall sense in government is of disquiet, and a bad job is made of hushing up the casualty figures. This gives fuel to the rumours of a severe defeat, and many people set greater store on the numbers put about by confederate supporters.

Sir Ralph Lane, the muster-master-general, informs the queen’s principal secretary, William Cecil, 1st Baron Burghley, that “more men were hurt and killed in that late service than was convenient to declare.” The casualty figures for both sides vary depending on sources. Bagenal admits only 31 killed and 109 wounded on the second day of fighting, but his losses are almost certainly higher. The Irish annals claimed up to 700 English killed. Estimates of the confederate losses vary between 100 to 400 killed. Three years later, Bagenal leads an army into another ambush by Tyrone, at the Battle of the Yellow Ford. The English general is killed and his troops are routed with heavy losses.
