William's army proceeded slowly to Dublin. The Duke of Ormond entered the city two days after the battle of the Boyne, at the head of nine troops of horse. On the next day the King, with his whole army, marched to Finglas, in the neighbourhood of Dublin; and on the 6th of July he entered the city, and proceeded to St. Patrick's Church, to return thanks for his victory. The whole of the Irish army proceeded towards Athlone and Limerick, intending to carry on the war behind the Shannon. William sent a body of his troops, under Lieutenant-General Douglas, to Athlone, while he himself proceeded to reduce and occupy the towns of the South. Rapin followed his leader, and hence his next appearance at the siege of Athlone. Rapin conducted himself throughout the Irish campaign as a true soldier. He was attentive, accurate, skilful, and brave. He did the work he had to do without any fuss; but he _did_ it. Lieutenant-General Douglas, under whom he served, soon ascertained his merits, saw through his character, and became much attached to him. He promoted him to the rank of aide-de-camp, so that he might have this able Frenchman continually about his person. Douglas proceeded westward, with six regiments of horse and ten of foot, to reduce Athlone. But the place was by far too strong for so small a force to besiege, and still less to take it. Athlone had always been a stronghold. For centuries the bridge and castle had formed the great highway into Connaught. The Irish town is defended on the eastern side by the Shannon, a deep and wide river, almost impossible to pass in the face of a hostile army. Douglas summoned the Irish garrison to surrender. Colonel Richard Grace, the gallant old governor, returned a passionate defiance. "These are my terms," he said, discharging a pistol at the messenger: "when my provisions are consumed, I will defend my trust until I have eaten my boots." Abandoning as indefensible the English part of the town, situated on the east side of the Shannon, Grace set fire to it, and retired with all his forces to the western side, blowing up an arch of the bridge behind him. The English then brought up the few cannon they had with them, and commenced battering the walls. The Irish had more cannon, and defended themselves with vigour. The besiegers made a breach in the castle, but it was too high and too small for an assault. "Notwithstanding this," says Rapin, "the firing continued very brisk on both sides; but the besiegers having lost Mr. Neilson, their best gunner, and the cavalry suffering very much for want of forage; and at the same time it being reported that Sarsfield was advancing with fifteen thousand men to relieve the place, Douglas held a council of war, wherein it was thought fit to raise the siege, which he accordingly did on the 25th, having lost near four hundred men before the town, the greatest part of whom died of sickness."
