Fitz-Stephen, on returning to Wales, had helped Diarmait Mac Murchada to organize a mercenary army of Norman and Welsh soldiers, including Richard de Clare, second Earl of Pembroke, alias Strongbow.

The first Norman knight to land in Ireland had been Richard fitz Godbert de Roche in 1167, but it is not until May 1, 1169, that Robert leads the vanguard of Diarmait Mac Murchada's Cambro-Norman auxiliaries to Ireland, thereby precipitating the Norman invasion of Ireland.
