While Richard was assembling his succors, Dermot went into Wales; and meeting with Robert Fitz-Stephens, constable of Abertivi, and Maurice Fitz-Gerald he also engaged them in his service, and obtained their promise of invading Ireland.

Being now assured of succor, he returned privately to his own state; and lurking in the monastery of Fernes, which he had founded, (for this ruffian was also a founder of monasteries,) he prepared every thing for the reception of his English allies.
The troops of Fitz-Stephens were first ready.

That gentleman landed in Ireland with thirty knights, sixty esquires, and three hundred archers; but this small body, being brave men, not unacquainted with discipline, and completely armed,--a thing almost unknown in Ireland,--struck a great terror into the barbarous inhabitants, and seemed to menace them with some signal revolution.

The conjunction of Maurice de Prendergast, who, about the same time, brought over ten knights and sixty archers, enabled Fitz-Stephens to attempt the siege of Wexford, a town inhabited by the Danes; and after gaining an advantage, he made himself master of the place.

Soon after, Fitz-Gerald arrived with ten knights, thirty esquires, and a hundred archers; and being joined by the former adventurers, composed a force which nothing in Ireland was able to withstand.
