These considerations, enforced by the character of honor and constancy which Pembroke had ever maintained, had a mighty influence on the barons; and most of them began secretly to negotiate with him, and many of them openly returned to their duty. The diffidence which Lewis discovered of their fidelity, forwarded this general propension towards the king; and when the French prince refused the government of the castle of Hertford to Robert Fitz-Walter, who had been so active against the late king, and who claimed that fortress as his property, they plainly saw that the English were excluded from every trust, and that foreigners had engrossed all the confidence and affection of their new sovereign.[**] The excommunication, too, denounced by the legate against all the adherents of Lewis, failed not, in the turn which men’s dispositions had taken, to produce a mighty effect upon them; and they were easily persuaded to consider a cause as impious, for which they had already entertained an unsurmountable aversion.[***] Though Lewis made a journey to France, and brought over succors from that kingdom [****] he found, on his return, that his party was still more weakened by the desertion of his English confederates, and that the death of John had, contrary to his expectations, given an incurable wound to his cause. The earls of Salisbury Arundel, and Warrenne, together with William Mareschal, eldest son of the protector, had embraced Henry’s party; and every English nobleman was plainly watching for an opportunity of returning to his allegiance. * Rymer, vol. i. p. 215.
