The marriage revelry was hardly over when tidings came from Dublin that Asculph MacTorcall, its Danish lord, had, either by the refusal of the annual tribute, or in some other manner, declared his independence of Dermid, and invoked the aid of the monarch Roderick, in defence of that city. Other messengers brought news that Roderick had assumed the protection of Dublin, and was already encamped at the head of a large army at Clondalkin, with a view of intercepting the march of the invaders from the south. The whole Leinster and Norman force, with the exception of a troop of archers left to garrison Waterford, were now put in motion for the siege of the chief city of the Hibernicized descendants of the Northmen. Informed of Roderick's position, which covered Dublin on the south and west, Dermid and Richard followed boldly the mountain paths and difficult roads which led by the secluded city of Glendalough, and thence along the coast road from Bray towards the mouth of the Liffey, until they arrived unexpectedly within the lines of Roderick, to the amazement and terror of the townsmen. The force which now, under the command-in-chief of Dermid, sat down to the siege of Dublin, was far from being contemptible. For a year past he had been recognized in Leinster as fully as any of his predecessors, and had so strengthened his military position as to propose nothing short of the conquest of the whole country. His choice of a line of march sufficiently shows how thoroughly he had overcome the former hostility of the stubborn mountaineers of Wicklow. The exact numbers which he encamped before the gates of Dublin are nowhere given, but on the march from Waterford, the vanguard, led by Milo de Cogan, consisted of 700 Normans and "an Irish battalion," which, taken literally, would mean 3,000 men, under Donald _Kavanagh_; Raymond the Fat followed "with 800 British;" Dermid led on "the chief part of the Irish" (number not given), in person; Richard commanded the rear-guard, "300 British and 1,000 Irish soldiers." Altogether, it is not exorbitant to conjecture that the Leinster Prince led to the siege of Dublin an army of about 10,000 native troops, 1,500 Welsh and Flemish archers, and 250 knights. Except the handful who remained with Fitzstephen to defend his fort at Carrick, on the Slaney, and the archers left in Waterford, the entire Norman force in Ireland, at this time, were united in the siege. Of the foreign knights many were eminent for courage and capacity, both in peace and war. The most distinguished among them were Maurice Fitzgerald, the common ancestor of the Geraldines of Desmond and Kildare; Raymond the Fat, ancestor of the Graces of Ossory; the two Fitz-Henries, grandsons of Henry I., and the fair Nesta; Walter de Riddlesford, first Baron of Bray; Robert de Quincy, son-in-law and standard-bearer to Earl Richard; Herve, uncle to the Earl, and Gilbert de Clare, his son; Milo de Cogan, the first who entered Dublin by
