14. _The papal charge._ The cause of the crusade is delayed by him through the quarrel which he has with certain Lombards, although the church is ready to use all her powers to secure proper satisfaction from the Lombards for what they have done against the emperor, and the Lombards themselves are ready to make satisfaction. _The emperor's answer._ He had often referred that matter to the church, but he had never received any satisfaction. For the first time, the Lombards were condemned to furnish 400 knights. But instead of sending them to aid the emperor, as they should, the pope used them to make war on the emperor. The second time, they were condemned to furnish 500 knights, but the pope declared that they should not be sent to the aid of the emperor, but that they should be sent on the crusade under the control and protection of the pope and the church. But not even this was done. The third time, at the request of the cardinals, the Sabine bishop and _Magister_ Peter of Capua, the affair was again referred to the pope exactly as the pope desired. But afterward the matter was never mentioned again until the pope learned that the emperor, having been deceived so many times about it, was preparing to lead an army from Germany into Italy. And then the pope at once begged that the matter be referred to him again. And although the emperor had so often been deceived in submitting it to the pope, he nevertheless was willing to submit it to him once more, but a time limit was set and it was stipulated that it should be decided to the honor of the emperor and to the advantage of the empire. But the pope was not willing to accept these conditions, as may be proved by his letter, although he now says that he was ready to decide the case in accordance with the rights and honor of the empire. From this it is apparent that the pope's letters are contradictory to each other. And let the pope not pretend that the emperor, in trying to restore the rights of the empire in Italy, injured the prospects of the crusade, for the letters which the emperor wrote in answer to the kings of the world and to the crusaders in France, who had chosen him as their leader, will show that he took charge of the crusade and did not neglect it. He also wrote that he wished to conduct the whole matter in accordance with the advice of the church.... Finally, the emperor declared that since he had been absent from the kingdom and did not know the exact condition of things, if anything had been done injurious to the church, and had not yet been corrected, he would order it to be set entirely right, and also because of the great general good which would come if there were harmony between him and the church, he would give the church any reasonable security that he would act in harmony with her, and use all his powers and means for the honor and advancement of the Christian church and for the preservation of her liberties. 144.
