With such an onlooker as this Henry knew that he must play his game with the utmost caution. He had been provoked by the personal opposition of his old friend into standing upon his regal dignity more stiffly than he would have thought it worth while to do so long as it remained unchallenged. On his side, too, there was a principle at stake, and he could not give it up unconditionally; but he might have been induced to accept a compromise, had not the obstinacy of Thomas forced him into a corresponding attitude of unbending determination. So keen was his sense of the danger attendant upon the fugitive archbishop’s presence in France that it led him to postpone once more the work which he had been planning in England and cross over to Normandy again early in 1165.[219] Lent was passed in fruitless attempts to bring about a triple conference between the two kings and the Pope; Henry refused to allow Thomas to be present; Thomas begged the Pope not to expose himself to Henry’s wiles without him who alone could help him to see through them; and Alexander, now busy with preparations for his return to Rome, was probably not sorry to escape by declaring that for a temporal prince to dictate who should or who should not form part of the Pope’s suite was a claim which had never been heard of before and which he could not possibly admit.[220] Immediately after Easter he set out on his journey homewards.
