During all Napoleon's military operations he never allowed himself to be besieged in any place. How, then, are we to reconcile this fact with the instructions that he sent to Masséna? Why should he order Masséna to take up a position which would allow his army to be besieged, and finally to be captured or destroyed? To answer satisfactorily these questions, it is necessary to consider the operations of Masséna in connection with the projected operations of Bonaparte. The Army of Italy was essentially a containing force. Its duty was to hold Melas in check for a time. How Masséna could best _prolong_ the conflict was the problem that Bonaparte was solving. That the Army of Italy should finally be defeated was of small consequence; that it should not be defeated before Bonaparte had time to effect the destruction of Melas was of great consequence. If it could hold out till then, the victory of Bonaparte over Melas would render nugatory the triumph of Melas over Masséna. If it could hold out till then, the success of Melas at Genoa would avail him nothing; for it would be swallowed up by a greater success, which was destined to produce far greater results. Bonaparte believed that Masséna was strong enough to hold Melas in check; and since every spare man was needed to strengthen Moreau's army and the Army of Reserve, he would not send any re-enforcements to the Army of Italy. Doubtless an ordinary general would have marched the entire Army of Reserve to the support of Masséna. What would have been the result? With only eighty thousand Frenchmen to oppose one hundred and twenty thousand Austrians, there would have been a long struggle in Italy. Guided by the genius of Bonaparte the French might have repeated the successes of 1796-97; but even had they done so, months of hard fighting would have been necessary in order to drive the Austrians out of northern Italy. In the Marengo campaign Bonaparte expected to accomplish as great results in less time. The struggle for the mastery was to take place, not along the Apennines, but in the valley of the Po. Thus it was that no re-enforcements were sent to Masséna, and that little or nothing was done to improve the condition of the Army of Italy. "It must be admitted," says Thiers, "that the army of Liguria[6] was treated a little as a sacrificed army. Not a man was sent to it. Materials of war only were supplied to it; and even under that head such only as were absolutely needful. It was in a different direction that the great efforts of the government were exerted, because it was in a different direction that the great blows were to be dealt. The army of Liguria was exposed to destruction in order to gain the time which should render the others victorious. Such is the hard necessity of war, which passes over the heads of these to strike the heads of those; obliging those to die that these may live and conquer."
