Leaving a strong garrison, the Normans marched to Dublin, which town, as well as that of Waterford, had been founded by the Danes. Supported by reinforcements raised by MacMurrogh, the invaders took the city of Dublin with little resistance, and, elated by a course of uninterrupted successes, made incursions upon the surrounding country. King Henry, however, received the news of these events, and his jealousy being excited at such an important conquest being attained by his vassals, he issued a proclamation forbidding any vessel to leave his dominions for Ireland, and ordered all his subjects then in that country to return to England by the next Easter, on pain of the forfeiture of all their estates, and of perpetual banishment from the realm. A consultation was held among the Normans, and Raymond Fitz-William, surnamed Le Gros, nephew of Fitz-Gerald and Fitz-Stephen, was dispatched on a mission to Henry, to prevail upon him to recall the proclamation, and to remind him of the letters he had given to MacMurrogh, authorising Englishmen to take up arms in his cause. Henry received the message without returning any answer, or, according to some of the chroniclers, he replied by confiscating the estates of Strongbow in Wales. While the earl thus found himself cut off from all reinforcements of men and arms, the Normans in Leinster were suddenly attacked by the men of Danish race who were settled on the north-east coast of Ireland, and who now allied themselves with the natives against the new invaders. They attacked Dublin, but without success. The Normans, however, dreading the formidable league against them, made a second application to Henry through Hervey Fitz-Maurice. Strongbow himself was then ordered to proceed to the court, and after some delay he obtained an audience. The earl agreed to surrender to the king the town of Dublin, with the larger of the other towns on the coast; in return, Strongbow was permitted to retain his other acquisitions in Ireland, and was restored to the possession of his estates in Wales. MacMurrogh having died previously to this interview, Strongbow had assumed the title of King of Leinster, in right of his wife Eva; and he now found himself reduced from the condition of a sovereign prince to that of steward of the English crown. In the year 1171, Henry set sail from Milford to take possession of his new territories. The royal force consisted of 400 vessels, containing about 5,000 men, among whom were 500 knights. Henry landed at the Crook, near Waterford, October 18th, and was received by the Norman chiefs, who tendered him their homage. The army commenced its march, by way of Cashel, to Dublin, meeting with no resistance. The inhabitants, overawed by the numbers and the martial equipment of their enemies, fled in dismay before the advancing troops, and the native kings of the south had no other alternative than to surrender at the summons of the conqueror, and offer their allegiance to him.
