With a large and brave army, capable of doing great things, if it had been properly led, Melas so scattered it and dissipated his strength that he virtually accomplished nothing. Though he commanded one hundred and twenty thousand men, he brought but twenty-five thousand upon the vital point. In short, he committed blunder upon blunder, and finally failed in his undertaking. The problem before Masséna was to hold in check the Austrians in Italy until Bonaparte could perfect his arrangements, cross the Alps, and strike the Austrian rear. Masséna could not expect to do more than this; for he could not take the offensive single-handed against an Austrian army three times the size of his own. Moreover, he was in possession of the strong defensive positions of Genoa, of the Apennines and Maritime Alps, and of the line of the Var, where inferior numbers could make a vigorous resistance against greatly superior forces. Masséna could not know how soon Bonaparte would cross the Alps. His object, therefore, was so to arrange his troops as to enable them to hold out as long as possible. At the outset of the campaign the Army of Italy was stationed as follows: eight thousand were at Genoa; twelve thousand, in the vicinity of Savona; twelve thousand, at the Tenda Pass, at Nice, and along the Var; and four thousand, in the Mont Cenis Pass. By examining the several positions on the map, it will be seen that the French forces were greatly scattered. Thirty-two thousand, under the direct command of Masséna, were defending the line of the Apennines and Maritime Alps from Genoa to the Col di Tenda, a distance of about seventy-five miles; and four thousand, under Thurreau, were holding the Mont Cenis Pass, which lies in the French Alps about one hundred and twenty miles north of Nice. Inasmuch as the direct road from Italy into France crossed the Alps over this pass, it was necessary to leave Thurreau's detachment there. Otherwise an Austrian corps of several thousand could have crossed the Alps at this point, thence have marched south along the west side of the mountains, and have attacked the French on the Var in rear, while Melas with his main forces was advancing across the Apennines to attack them in front. Moreover, in this favorable position, Thurreau, unless strongly opposed, could descend the Alps and fall upon the flank and rear of the Austrians as they advanced towards Nice. It was necessary, therefore, for Melas to leave ten or twelve thousand soldiers of the Austrian rear guard near the Italian entrance to the Mont Cenis Pass in order to hold Thurreau in check. Thus, though this French detachment could take no active part in the engagements along the Apennines and Maritime Alps, its four thousand men did good service in the struggle by rendering nugatory the fighting power of a much larger Austrian force.
