When they reached the farther bank, they perceived the enemy drawn up in two lines, to a considerable number of horse and foot, with a morass in their front, so that Douglas was obliged to wait for a reinforcement.

This being arrived, the infantry was led on to the charge through the morass, while count Schomberg rode round it with his cavalry to attack the enemy in flank.

The Irish, instead of waiting the assault, faced about and retreated towards Duleck with some precipitation; yet not so fast but that Schomberg fell in among their rear and did considerable execution.
King James however soon reinforced his left wing from the centre; and the count was in his turn obliged to send for assistance.

At this juncture, king William's main body, consisting of the Dutch guards, the French regiments, and some battalions of English, passed the river, which was waist high, under a general discharge of artillery.

King James had imprudently removed his cannon from the other side; but he had posted a strong body of musqueteers along the bank, behind hedges, houses, and some works raised for the occasion.
