The leaders yielded so far to his advice as to take up a position where they would fight with the best chance of success.

The spot lay between a swamp extending a vast distance, and a river, and they were thus open only to an attack in front, and could, if defeated, take refuge in the bog, where horsemen could not follow them.
On the following morning the English were seen approaching.

In addition to the 800 men-at-arms were 1000 lightly equipped footmen, for experience had taught the English commanders that in such a country lightly armed men were necessary to operate where the wide extending morasses prevented the employment of cavalry.

The English advanced in solid array: 300 archers led the way; these were followed by 700 spearmen, and the men-at-arms brought up the rear.
The Irish were formed in disordered masses, each under its own chieftain.

The English archers commenced the fight with a shower of arrows.
