The Inniskilliners were no less remarkable than the people of Londonderry for the valour and perseverance with which they opposed the papists. They raised twelve companies, which they regimented under the command of Gustavus Hamilton, whom they chose for their governor. They proclaimed William and Mary on the eleventh day of March, and resolved in a general council to maintain their title against all opposition. The lord Gilmoy invested the castle of Groin belonging to the protestants in the neighbourhood of Inniskilling, the inhabitants of which threw succours into the place, and compelled Gilmoy to retire to Belturbet. A detachment of the garrison, commanded by lieutenant-colonel Lloyd, took and demolished the castle of Aughor, and they gained the advantage in several skirmishes with the enemy. On the day that preceded the relief of Londonderry, they defeated six thousand Irish papists at a place called Newton-Butler, and took their commander Macarty, commonly called lord Moncashel.
