The Irish had, this time, determined to defend not only that portion of Athlone situated on the west of the river, but the English town on the east.

The fortifications here were repaired and added to, and the town was abundantly supplied with stores and ammunition.

It was, however, unable to resist the heavy artillery which Ginckle brought to play against it.

Walls, buildings, and towers crumbled beneath the heavy cannonade; and although the Irish repelled, with great slaughter, several assaults upon it, the place became at last untenable, and they abandoned that part of the town, and retired by the bridge across the river to the Irish town.
The British, on entering the eastern town, found it a mere mass of ruins, with the dead bodies of the soldiers lying everywhere, half covered with the wreck of the works they had died in defending.

The taking of this portion of Athlone had cost Ginckle dearly, and he was but little nearer the object of his efforts, for he was separated from the Irish town by the Shannon, and the western arch of the bridge was broken down by the defenders.
Eleven large guns and three mortars now came up from Dublin, and he erected a succession of batteries upon the ruins of the English town, and opened fire upon the castle of Athlone, which, although a building of great strength, soon crumbled into ruins beneath the fire of the heavy artillery brought to bear upon it.
