Godert de Ginkel, the commanding general of William III‘s army, begins a ten-day siege of Athlone on June 20, 1691. Athlone is besieged twice during the Williamite War in Ireland (1689–91). The town is situated in the centre of Ireland on the River Shannon and commands the bridge crossing the river into the Jacobite-held province of Connacht. For this reason, it is of key strategic importance.

The army of William III first besieges Athlone in 1690, shortly after their defeat of the main Jacobite army at the Battle of the Boyne. James Douglas and about 7,500 troops attempt to take the town, but the Jacobite garrison’s commander, Colonel Richard Grace, refuses to surrender. Lacking siege artillery, Douglas is forced to withdraw after a week.

In the summer of the following year, the Williamite army, having regrouped at Mullingar under the command of Dutch general Godert de Ginkel, marches via Ballymore to make a second attempt on Athlone.

The Jacobite commander, Charles Chalmot de Saint-Ruhe, marches his main field army from its winter quarters in Limerick to meet the threat. He draws up his force to the west of the town. Other Jacobite troops man fortifications in the ruins of the “English Town,” the eastern half of Athlone, along with a garrison in the “Irish Town” on the western bank. This arrangement is intended to allow the Jacobites to fight a staggered, drawn-out defence, though the advantage is reduced by high ground on the Leinster bank of the Shannon and the fact that the river is running exceptionally low at the time.

Jacobite defences are also hampered by disagreements between James’s Viceroy, Richard Talbot, 1st Earl of Tyrconnell, Saint-Ruhe, and Jacobite general Patrick Sarsfield. When Talbot asserts his seniority and offers advice on the defences to Saint-Ruhe, the latter refuses to recognise Talbot’s command, while Sarsfield sends him a message that his pavilion ropes will be cut if he does not leave immediately. Though Talbot surmises that a large number of the best Jacobite troops will side with him, he chooses to depart for Limerick rather than split the army.

Ginkel opens an assault on the eastern part of Athlone on June 20, which causes the Jacobites to retreat to the west bank of the river, dismantling the bridge in the process. Colonel Grace, who had been superseded as garrison commander by the French officer d’Usson, is killed in a bombardment at the western end of the bridge on the same day.

The Jacobite forces in the western half of Athlone, led by Major-General Thomas Maxwell, a Scottish Catholic, initially hold off the Williamite assault. There is fierce fighting centred on the bridge over the Shannon. The Williamites try to lay planks over the partially wrecked structure, which the Irish Jacobite troops manage to destroy despite coming under intense fire. One such Jacobite sortie, by a small group of volunteers from Maxwell’s dragoon regiment led by a Sergeant Custume or Costy, all of whom are killed, later passes into Irish folklore as an example of bravery. Several attempts by the Williamites to storm the bridge are repulsed with heavy losses.

The Williamite bombardment of the western, Connacht, side of the town is intense, with over 12,000 cannonballs and 600 bombs or mortars fired into the town. John Stevens, serving in the Grand Prior’s Regiment, records that “with the balls and bombs flying so thick, that spot was hell on earth.” During the ten-day bombardment, 32 heavy cannon and mortars fire one shot every minute. Athlone suffers the heaviest bombardment of any city in Britain and Ireland up to this point.

While developing a plan to storm the bridge, Ginkel identifies another potential crossing point at a ford to the south. To test the crossing, on the morning of June 29 he orders a Danish quartermaster and two privates, under sentence of death for cowardice, to ford the river while troops fire over their heads to give the impression they are deserting. All three ford to the western bank and return safely, whereupon Ginkel sends a force of grenadiers, 2,000 strong, to cross there and attack the Jacobite positions from the rear.

Following an argument between Saint-Ruhe and the garrison commander d’Usson, the fortifications on the western side of the city have not been levelled, as Talbot had suggested some days earlier. Saint-Ruhe does not issue an order to demolish them until June 29, apparently believing it impossible that a city could be taken with a relieving army so close by. They remain standing a day later, and a party of Ginkel’s grenadiers hurry to occupy them and raise the drawbridge there, holding off counterattacks from Saint-Ruhe’s army until the main Williamite force can be brought up. Saint-Ruhe detaches two brigades under Major-General John Hamilton to dislodge the Williamites, but after approximately an hour and a half of intense fighting, the Jacobites retreat.

The breakthrough of the Williamites forces the remains of the Jacobite garrison, who have been awaiting reinforcement from the main Jacobite force under Saint-Ruhe, to hastily abandon their positions in Athlone. Maxwell is captured. Accusations of treachery are later levelled at him, partly as he had been a supporter of Talbot’s faction. Saint-Ruhe withdraws into County Galway, passing through Ballinasloe. The Jacobites lose around 1,000 men at Athlone, though the highest estimates suggest losses of over 2,000, including colonels McGuinness, McMahon and O’Gara, in addition to Grace.

Ginkel continues to march toward Limerick, unaware of the position of Saint-Ruhe. On the morning of July 12, the Williamites are confronted by the main Jacobite army drawn up in a strong defensive position at Aughrim. In the ensuing Battle of Aughrim, Ginkel inflicts a crushing defeat on them, effectively ending Jacobite resistance in Ireland.
