Limerick was, at that time, the second city in Ireland. The country, for a long distance along the mouth of the Shannon, was much wooded, but in the immediate vicinity of the town it was surrounded by thick inclosures, houses, orchards, gardens, and plantations. The cultivated land was everywhere divided into small fields, inclosed by hedges and intersected by lanes. To the east of the town the Shannon divides itself, forming an island on which part of the city is situated. This was called the English town, and was connected by a bridge, called Thomond Bridge, with the Clare side of the river on the north; and on the south, by another bridge, with the Irish town on the county of Limerick side. The Thomond Bridge was defended by a strong fort and some field works on the Clare side, and on the city side by a drawbridge, flanked by towers and the city walls. The bridge was very long and narrow. The position of the English town was, indeed, almost impregnable. It was built upon a rock of considerable extent, and the land outside the walls was low and marshy, and could at any time be flooded. The Shannon was broad and rapid. The Irish town on the Limerick shore was not strong, being defended only by ordinary walls. If this were captured, however, the English town could still hold out. The king made his approaches to the city slowly, being obliged to level the numerous inclosures as he moved on. These were occupied by the Irish infantry, who, lining every hedge, kept up a galling fire, falling back gradually as heavy bodies of troops were brought up against them, until they reached the cover of the guns of the city and fort. Upon these opening fire, William's army halted and encamped before the Irish town. Here, as at the Boyne, the king had a narrow escape, a cannonball from the walls striking the ground at his foot as he was passing through a gap in a hedge. The king had learned that great dissensions existed between the Irish and French, and relied upon this, as much as upon the strength of his arms, to obtain possession of the city. His information was, indeed, correct. King James, in his flight, had left no orders as to who should assume the supreme command. The Duke of Berwick had considerable claims. Lauzun and the French officers declined altogether to receive orders from Tyrconnell, and the Irish officers equally objected to act under the command of a Frenchman. Consequently, during the whole siege, the main Irish army, which, by acting upon William's rear, could speedily have made his position untenable, remained inactive. Monsieur Boileau, a French officer, was governor of the town, but Lauzun, having examined the fortifications, pronounced the place wholly incapable of defence, declaring that the walls could be knocked down with roasted apples, and so ordered the entire French division to march to Galway, and there await an opportunity for embarking for France, leaving the Irish to defend the city if they chose.
