“ At the close of 1208 William de Braose [q. v.] fled to Ireland, and landing at Wicklow was well received by Marshal, who, despite the new justiciar, John de Grey [q. v.] , escorted him in safety to Walter de Lacy. Marshal had already been acting in conjunction with the De Lacys (Four Masters, iii. 155) , and this harbouring of William de Braose led to John's Irish expedition in June 1210 (Sweetman, i. 408) . Marshal had come over to England earlier in the year at John's bidding, and apparently recrossed with the king. ”
