As soon as Bonaparte learned of the hopeless condition of affairs at Genoa, he saw the necessity of hurrying across the Alps with the Army of Reserve. But since the successful execution of his plan depended upon his receiving a large re-enforcement from the Army of the Rhine, and since Moreau could not safely detach this force till he had defeated Kray and pushed him back from Lake Constance, Bonaparte was compelled to delay his own movement. Moreau was slow to begin; and his lingering inactivity gave Bonaparte intense anxiety, for it not only paralyzed the operations of the Army of Reserve, but prolonged the sufferings of the Army of Italy. Repeatedly Bonaparte urged Moreau to cross the Rhine and attack Kray. "Hasten," said the First Consul, "hasten by your success to accelerate the arrival of the moment at which Masséna can be disengaged. That general wants provisions. For fifteen days he has been enduring with his debilitated soldiers a struggle of despair. Your patriotism is addressed, your self-interest; for if Masséna shall be compelled to capitulate, it will be necessary to take from you a part of your forces, for the purpose of hurrying down the Rhone, in order to assist the departments of the south." Finally, on the 25th of April, Moreau began his advance against Kray. It is not the intention at this time to describe in detail these operations. At present it is sufficient to say that Moreau executed vigorously his part in Bonaparte's great plan. Having defeated Kray in two battles, he detached, on the 11th of May, a corps of fifteen thousand men from his army, gave the command of it to General Moncey, and ordered him to march by way of the St. Gothard into Italy. The time had come for Bonaparte to move forward the Army of Reserve. Accordingly, on the 15th of May, he began his advance by way of the Great St. Bernard into Italy. While this army of forty thousand and this corps of fifteen thousand are marching hopefully forward across the Alps, from France and Germany respectively, let us again turn our attention to Masséna, who, amidst famine and death, is desperately fighting on. On the 5th of May a small vessel, containing grain sufficient to last the besieged garrison for five days, ran the blockade and entered Genoa. Masséna felt encouraged, and shortly afterwards made a sortie on the east side of the city. Though he drove the Austrians from their positions, this assault was the last of his successes. On the 13th of May he attempted another assault, but was badly defeated. Henceforth his soldiers were so weak that they lacked the strength to undertake any movement beyond the walls of Genoa. In fact, many, not being able to bear the weight of their arms, were compelled to sit down while doing guard duty. Consequently, Masséna was obliged to limit his efforts to the defence of the city, and to the task of providing food for his men.
