The fact that he had only achieved a small part of the conquest he professed to set out to accomplish was, therefore, no bar to negotiations for peace. There were many reasons for ending the war; the rapid diminution of his father's treasures; the accession to the papal throne of the pacific Leo in place of the warlike Julius; the absolution of Louis as a reward for renouncing the council of Pisa; the interruption of the trade with Venice; the attention required by Scotland now that her king was Henry's infant nephew; and lastly, his betrayal first by Ferdinand and now by the Emperor. In October, 1513, at Lille, a treaty had been drawn up binding Henry, Maximilian and Ferdinand to a combined invasion of France before the following June.[149] On 6th December, Ferdinand wrote to Henry to say he (p. 070) had signed the treaty. He pointed out the sacrifices he was making in so doing; he was induced to make them by considering that the war was to be waged in the interests of the Holy Church, of Maximilian, Henry, and Catherine, and by his wish and hope to live and die in friendship with the Emperor and the King of England. He thought, however, that to make sure of the assistance of God, the allies ought to bind themselves, if He gave them the victory, to undertake a general war on the infidel.[150] Ferdinand seems to have imagined that he could dupe the Almighty as easily as he hoped to cheat his allies, by a pledge which he never meant to fulfil. A fortnight after this despatch he ordered Carroz not to ratify the treaty he himself had already signed.[151] The reason was not far to seek. He was deluding himself with the hope, which Louis shrewdly encouraged, that the French King would, after his recent reverses, fall in with the Spaniard's Italian plans.[152] Louis might even, he thought, of his own accord cede Milan and Genoa, which would annihilate the French King's influence in Italy, and greatly facilitate the attack on Venice.
