The Enniskilleners had never ceased to wage a vigorous partisan war against the native population.

Early in May they marched to encounter a large body of troops from Connaught, who had made an inroad into Donegal.

The Irish were speedily routed, and fled to Sligo with the loss of a hundred and twenty men killed and sixty taken.
Two small pieces of artillery and several horses fell into the hands of the conquerors.

Elated by this success, the Enniskilleners soon invaded the county of Cavan, drove before them fifteen hundred of James's troops, took and destroyed the castle of Ballincarrig, reputed the strongest in that part of the kingdom, and carried off the pikes and muskets of the garrison.

The next incursion was into Meath.
