The attack made by the army of King James having been repulsed, the town was invested on the 20th of April. The garrison of LONDONDERRY consisted of seven thousand untrained countrymen, without engineers; the town was not well fortified; twenty guns only were on the walls, and not one of them well mounted; yet the city was successfully defended, for more than three months, against a formidable army, which proves how much depends on bravery and resolution. The garrison made several gallant sorties, and inflicted severe loss on the besieging troops. Meanwhile the INNISKILLING men under Gustavus Hamilton were not inactive. Lieutenant-Colonel Lloyd made a successful incursion into the enemy's quarters, took and burnt the fortifications of _Augher_, and returned to Inniskilling with an immense number of cattle. The same officer routed a body of King James's troops at _Belleek_, killing a hundred soldiers, taking thirty prisoners, and capturing two guns; and he threw a relief into Ballyshannon on the 8th of May, without the loss of a man, which proved a brilliant commencement of aggressive warfare: he also captured the enemy's garrison at Redhill, and the castle of _Ballynecarreg_, in the county of Cavan; and Captains Francis Gore and Arnold Crosbie brought off two hundred troop horses from a pasture at _Omagh_, which mounted three troops of Inniskilling men. The garrison of Londonderry becoming distressed for want of provisions, the INNISKILLING men advanced to its relief; but the approach of a body of troops, under Major-General Sarsfield, to besiege Ballyshannon, and of another, under Colonel Sutherland, to Belturbet, with the view of besieging the town of INNISKILLING, obliged them to return and defend their own quarters. The gallant Lieutenant-Colonel Lloyd was detached against _Belturbet_, from whence Colonel Sutherland fled, on the 15th of June, leaving a detachment of dragoons to defend the church, who surrendered, and the INNISKILLING men gained possession of a supply of ammunition and provisions, eighty troop horses with accoutrements, and seven hundred muskets, which enabled them to equip themselves better than before, and to add several new companies to their levies.
