That night the forces entrenched themselves between the castle and the river, and the next day, under the guise of a parley, they managed to plant the cannon without opposition. The next day the Knight of Glin, who was not within the castle, asked for a safe conduct to the English camp, which was granted. Upon arrival he demanded to see the President, but was refused unless upon an unconditional surrender. This he would not consent to, and was, therefore, ordered to depart. Seeing his son in the camp, whom he had delivered as a hostage some time previously, he seemed to hesitate, but as he still held out for terms the Earl of Thomond broke off the negotiations, and the Knight and his attendants retired to a neighbouring hill to watch the attack. Later the Constable of the fortress sent a message to the Earl of Thomond begging an interview, which was granted. He began by stating that the love he bore the Earl, being a Thomond man himself, had induced him to warn the English to depart, as the Earl of Desmond with three thousand Connaught men were only two miles off, and would most likely attack the camp and drive them all into the river. The Earl laughed at his forebodings, and told him to deliver the castle and so save himself and the warders from death. This offer he refused, and the President, hearing he had done so, sent a message to say that he hoped to place his head on a stake in two days’ time. One of the cannon becoming clogged, Sir George Carew ordered it to be filled with a charge in inverted order and the fire put to the mouth, so as to clear the touch-hole by the explosion. This was carried out with great success, much to the relief of the besiegers. A fire of small shot was kept up from the castle at the ordnance, and the President, placing the Knight’s son on one of the cannon, sent a message to the garrison to say he had given them a mark to aim at. The Constable replied that the Knight of Glin might have more sons, and that the child should not deter him from firing. Sir George Carew, however, removed the child, and commenced the battery. A breach was made into the cellar under the great hall, one gunner only being killed. Captain Flower then led the attack and entered the hall through the breach, forcing the ward to retire. The flag of the besiegers was hoisted from the turrets of the hall, and night coming on Captain Slingsby was ordered to hold the position until the morning. A dropping fire was kept up all night. The Constable, seeing that to successfully hold the castle was impossible, tried to escape with some of the warders, but he and others were killed in the attempt, one only getting away. His head was placed upon a stake in the camp as the President had said.
