As one of the largest military installations in the country Charles Fort has been associated with some of the most momentous events in Irish history. The most significant of these include the Jacobite-Williamite War in 1690 and the Irish Civil War in 1922 – 1923.
As a military fortress Charles Fort is an outstanding example of star-shaped fort with five bastions. Built between 1688 and 1692, Charles Fort was designed by William Robinson, Architect of the Royal Hospital Kilmainham and Superintendent of all fortifications in Ireland. In his design of Charles Fort, Robinson was influenced by the work of the French Engineer, Sebastien de Vauban, who perfected this form of military architecture. These forts were the most effective form of defence during the age of cannon and musket fire.
At its height, there were 94 canons in Charles Fort in 1690 – a formidable deterrent for any attacker. Its walls are low and thick and are circa 12 metres wide. The fort is strong on its seaward side but the landward defences were never fully completed. This would contribute to its fall in the siege of 1690.
The succession of James II to the throne of England in 1685 ultimately lead to the War of the Two Kings. James’s refusal to accept the rights of parliament and his continued devotion to Catholicism was unacceptable to the majority of the English Lords. In 1689, Civil War broke out as King James landed in Kinsale in an attempt to regain the throne.
In 1690, the Williamite forces, under the joint command of John Churchill, Earl of Marlborough, and Ferdinand Wilhelm, Duke of Wurttemberg, arrived in Kinsale and attached both Charles Fort and James Fort. James Fort was besieged first but was forced to surrender when a barrel of gun-powder exploded, killing many of the garrison and destroying the main gate. After James Fort was captured, William’s army seized the defenders cannons and turned them on Charles Fort. They opened fire pinning down the defenders on the western side. The capture of James Fort made front page news on the London Gazette on the 16th October 1690.
Charles Fort had one great weakness in that, it was essentially, unfinished. The three landward facing bastions were only supposed to be temporary and were thus un-mortared. The masonry slipped along the face and flank of the Cockpit Bastion, which was described by the Jacobite engineers, as very weak. It was thus an obvious target for the attackers.
Churchill and Wurttemberg commanded 10,000 men. Williams’ army was a coalition of European forces which included, English, French Huguenots and Danish forces. The Jacobite Commander, Lieutenant Colonel Edward Scott, had close to 1,200 soldiers defending Charles Fort. Despite the odds against them, the defenders put up a fierce fight holding out for thirteen days. When seven Williamite warships appeared on the horizon, the defenders found themselves stretched to breaking point as the Williamite’s focused their efforts on the venerable eastern flank. From the high ground looking directly into the Fort, they positioned eight 24 pounder iron cannons and fired 60-80 cannonballs per hour for three days into that vulnerable position.
Eventually, the wall collapsed and the defenders were offered the choice of surrender or death. Facing over 5 to 1 odds and armed with obsolete weaponry, with many of the garrison unable to fight due to illness and battle wounds, the defenders had no choice but to submit. They were allowed to surrender under terms and to leave Charles Fort with their flags and weapons and march to Limerick where they continued to fight until the end of the war. Churchill and Wurttemberg took over commend of Charles Fort while Churchill appointed his brother Governor of Charles Fort and Kinsale.
News that Charles Fort had been captured arrived just as the London Gazette went to press for the 16th of October edition.
