He therefore ordered a large body of cavalry to be immediately despatched to meet the artillery on its way, and protect it into camp.
All day, Sarsfield remained in concealment among the mountains, until, towards evening, the train came in sight, moving slowly with its escort of two troops of dragoons along the high road.

He watched it until it halted, and encamped for the night, in a field beside the highway.

He waited until the horses were picketed, and the men engaged in making their encampment for the night.

Then the Irish cavalry burst down from the glen in which they had been hiding.

The officer in command sounded to horse, but it was too late; before the men were in the saddle, the Irish were upon them, and in a moment the two troops of dragoons were dispersed or killed.
Sarsfield's men at once set to, to collect the powder waggons, pontoons, and baggage of every description.
