It being settled that Moreau should proceed against the Austrians in his own way, Bonaparte now wished to come to an understanding with him by which a corps of twenty or twenty-five thousand men should, at the proper time, be detached from the Army of the Rhine, and be sent across Switzerland to unite in Italy with the Army of Reserve. But Moreau did not enter heartily into any of the plans proposed by the First Consul. In fact, both he and Bonaparte seemed to distrust each other. Whether from jealousy, or from honest convictions, Moreau opposed the plans of Bonaparte. Moreover, he had declared that he would not serve under the First Consul, should the latter unite the Army of Reserve with the Army of the Rhine. Naturally this opposition created in the mind of Bonaparte a doubt of Moreau's good faith. He feared that, at the critical moment, the commander of the Army of the Rhine might fail to send a corps into Italy. He was well aware that the commander of an army is always reluctant to weaken his forces after operations have begun; and he knew that circumstances might arise which would seem to justify Moreau in refusing to obey the orders of his superior. He therefore insisted that Moreau should sign a stipulation whereby he promised that, after pushing Kray back from Lake Constance, he would detach Lecourbe with twenty or twenty-five thousand men, and order him into Italy. This agreement was signed at Bâle by Moreau and General Berthier, the latter representing the First Consul. Nearly a month had passed since the arrangements between Bonaparte and Moreau had been completed. It was now the latter part of April, yet Moreau had made no movement to cross the Rhine and attack Kray. Naturally cautious and slow, he had postponed his advance from day to day, in order, if possible, to supply his army with everything necessary to increase its fighting power. He was short of cavalry and artillery horses, and had little or no camp equipage, and no intrenching tools. But at this time it was impossible for him to obtain everything he needed. Already Bonaparte had sent to the Army of the Rhine all the spare material of war that he could collect in France. Now he was anxious to have Moreau advance. Masséna was hard pressed at Genoa, and Bonaparte desired to march into Italy in order to relieve him. But to cross the Alps and throw himself upon the rear of Melas, while Kray remained undefeated in the Black Forest, was too hazardous an undertaking. Much therefore depended upon the early advance of Moreau. Repeatedly Bonaparte urged him to press forward, and finally sent him a positive order to cross the Rhine and attack Kray.
