The garrison consisted of three regiments of foot and nine troops of horse; and when Douglas erected his batteries and opened fire on the castle, they replied briskly, and their guns got the better of those in the batteries. A strong detachment of horse and mounted grenadiers was sent by Douglas to Lanesborough, some miles north of the town, with orders to pass the river at that point, but the post was held by Irish troops, who easily repulsed the attempt. It was next proposed to pass the river at a ford a short distance from the bridge; but the troops had little heart for the enterprise, as the ford was covered by field works erected by the Irish. The assailants were already reduced to considerable straits. They had consumed all provisions found in the town, plundering without mercy the Protestant inhabitants, who had been well treated by the Irish troops, while the conduct of the army effectually deterred the country people from bringing in provisions. The circulation of the report that General Sarsfield, with fifteen thousand men, was on the march to cut off the besiegers of Athlone, determined General Douglas to make a speedy retreat. In his fear of being cut off, he abandoned all his heavy baggage, and, quitting the high road, made his way by unfrequented routes, which added to the hardships of the march. In its retreat, the column was accompanied by the unhappy Protestant inhabitants, who feared to remain behind, lest the Irish should retaliate upon them the sufferings which had been inflicted upon their countrymen. In the meantime, the main English army had done but little. In Dublin, a commission had been appointed to examine into and forfeit the lands of all Catholics, and adherents of King James, and having set this machine at work, the king proceeded with his army southward through Carlow, Kilkenny, and Waterford, all of which places surrendered, the garrisons being allowed to march out, with their arms and baggage, to join their main army on the Shannon. At Waterford, the king received such serious news as to the state of things in England, that he determined to return home. On arriving at Dublin, he was overwhelmed with petitions from the inhabitants, as to the shameful conduct of the troops left in garrison there, especially those of Trelawney's, Schomberg's, and some other regiments of horse, who, the people complained, treated them, although Protestants, far worse than James's Catholic soldiers had done. Inquiry showed these complaints to be well founded, and, finding it impossible to restore order and discipline among them, the king at once sent these regiments back to England. Then, receiving better news from home, he again started to rejoin his army, and marched towards Limerick, being joined on his way by the division under Douglas, which had driven along with them all the cattle and horses of the country through which they had passed.
