The old duke was cut down and his party again routed, and at the same moment Walker, the clerical commander of Derry, received a mortal wound.
After his successful defence of Derry, this man had gone to London, where he had been feted and made much of, and had then attached himself to King William's army, where he posed as a high military authority, although much discouraged by the king, whom his arrogance and airs of authority displeased.
While in the centre William's forces were getting worsted, and on his right Douglas and Count Schomberg were inactive and powerless, he himself was leading his left wing across the river.

The passage was a difficult one, and the king himself was only extricated, with much exertion, from a quicksand into which his horse had plunged.
The Irish did not oppose the crossing, and as soon as his forces were across the stream, William ranged them in order.

They consisted of a large body of Danish, Dutch, and Enniskillen horse, and a considerable force of infantry.

As soon as all were in order the king, though still suffering from the wound he had received the day before, drew his sword and put himself at the head of his troops.
The Irish right wing, which consisted chiefly of infantry, moved forward to meet them, but perceiving the numerous cavalry, led by the king himself, preparing to take them in flank, they halted, faced about and marched slowly to the little hill of Donore.

Having gained this point, they again faced round and charged down upon the British, who had followed them closely.
At this moment the Irish cavalry, who had moved rapidly from the centre to the support of the right, charged down upon the Danish and Dutch horse led by the king, and no sooner had they come in contact than the Danes and Dutch turned and rode off, with the Irish cavalry in pursuit.
