But Edward, seconded by an English army of fifty thousand men, (for this is the number assigned by historians,[*]) was able to stop the career of his victories; and Philip, finding all the weak resources of his kingdom already exhausted, began to dread a reverse of fortune, and to apprehend an invasion on France itself.

The king of England, on the other hand, disappointed of assistance from Adolph, king of the Romans, which he had purchased at a very high price, and finding many urgent calls for his presence in England, was desirous of ending, on any honorable terms, a war which served only to divert his force from the execution of more important projects.

This disposition in both monarchs soon produced a cessation of hostilities for two years; and engaged them to submit their differences to the arbitration of Pope Boniface.
{1298.} Boniface was among the last of the sovereign pontiffs that exercised an authority over the temporal jurisdiction of princes; and these exorbitant pretensions, which he had been tempted to assume from the successful example of his predecessors, but of which the season was now past, involved him in so many calamities, and were attended with so unfortunate a catastrophe, that they have been secretly abandoned, though never openly relinquished, by his successors in the apostolic chair.

Edward and Philip, equally jealous of papal claims, took care to insert in their reference, that Boniface was made judge of the difference by their consent, as a private person, not by any right of his pontificate; and the pope, without seeming to be offended at this mortifying clause, proceeded to give a sentence between them, in which they both acquiesced.[*] He brought them to agree, that their union should be cemented by a double marriage; that of Edward himself, who was now a widower, with Margaret, Philip's sister, and that of the prince of Wales with Isabella, daughter of that monarch.[**] * Rymer, vol.ii.
