There was also another reason for haste, which was not yet known to the French leaders. Maximilian had long been uncertain and vacillating in his alliances, but had now definitely decided to join the side of Pope Julius and the King of Spain. As usual there were companies of German and Swiss mercenaries both in the Italian army and also with the French, and these owed some kind of allegiance to the sovereign of their land. Thus it was that the Emperor had sent word to the companies of German "landsknechte" that they were to retire home at once and were not to fight against the Spaniards. Now it so happened that this letter had only been seen by the Captain Jacob, who commanded these mercenaries in the French army, and he, being a great friend of Bayard, privately asked his advice, first telling him that having accepted the pay of the French King he had no intention of thus betraying him in the hour of battle. But he suggested that it would be well to hurry on the impending battle before other letters should come from the Emperor and give the men an excuse for retiring. The Good Knight saw how urgent the matter was and advised him to declare it to the general, the Duc de Nemours. Duke Gaston, who had now heard of the Emperor's letter, said that they had no choice, and also that his uncle, the King of France, was sending constant messengers to hurry on war operations as he was in sore straits. Bayard was asked to give his opinion, and he modestly replied that he had only just arrived and others might know more, but as far as he could learn, the besieged were promised that a large army from Naples and Rome would come to their help in a few days, certainly before Easter, and this was Maundy Thursday. "And on the other hand," he added, "our men have no provisions and the horses are reduced to eating willow leaves, so that each day's delay makes it worse for us. You see, too, the King our master writes to us every day to hasten our movements, therefore I advise that we give battle. But we must use all caution for we have to do with brave and good fighting men, and we cannot deny the risk and danger. There is one comfort: the Spaniards have been in Romagna for a year, fed like fish in the water till they are fat and full, while our men, having undergone much hardship, have longer breath. Remember that to him who fights longest the camp will remain."
