Maurice Regan, the "_Latiner_," or Secretary of Dermid, had advanced to the walls, and summoned the city to surrender, and deliver up "30 pledges" to his master, their lawful Prince. Asculph, son of Torcall, was in favour of the surrender, but the citizens could not agree among themselves as to hostages. No one was willing to trust himself to the notoriously untrustworthy Dermid. The Archbishop was then sent out on the part of the citizens to arrange the terms in detail. He was received with all reverence in the camp, but while he was deliberating with the commanders without, and the townsmen were anxiously awaiting his return, Milo de Cogan and Raymond the Fat, seizing the opportunity, broke into the city at the head of their companies, and began to put the inhabitants ruthlessly to the sword. They were soon followed by the whole force eager for massacre and pillage. The Archbishop hastened back to endeavour to stay the havoc which was being made of his people. He threw himself before the infuriated Irish and Normans, he threatened, he denounced, he bared his own breast to the swords of the assassins. All to little purpose; the blood fury exhausted itself before peace settled over the city. Its Danish chief, Asculph, with many of his followers, escaped to their ships, and fled to the Isle of Man and the Hebrides in search of succour and revenge. Roderick, unprepared to besiege the enemy who had thus outmarched and outwitted him at that season of the year—it could not be earlier than October—broke up his encampment at Clondalkin, and retired to Connaught. Earl Richard having appointed de Cogan his governor of Dublin, followed on the rear of the retreating _Ard-Righ_, at the instigation of McMurrogh, burning and plundering the churches of Kells, Clonard and Slane, and carrying off the hostages of East-Meath.
