At the outset the Austrian forces were greatly scattered. A few thousand were in Tuscany and in the Papal States; an Austrian garrison was occupying the fortress of Mantua, which is situated on the Mincio about twenty miles south of Lake Garda; twenty-five thousand were moving forward in two columns to attack Genoa; forty thousand were being directed on the Apennines and Maritime Alps; and thirty-five thousand were occupying the fortresses of northwestern Italy, and guarding the Italian entrances to the passes of the Alps. The purpose of Melas was to push forward across the Apennines and Maritime Alps, force the line of the Var, and invade France. How best to accomplish this project was the problem before him. Having an army of one hundred and twenty thousand soldiers and being opposed to but forty thousand, he believed that his force was sufficiently large to undertake the invasion of France. Since the French line directly in his front extended along the mountains from Genoa to the Col di Tenda, Melas could easily overwhelm the French centre and cut the Army of Italy in two; then, by leaving a sufficient force to surround Genoa, he could push forward vigorously to the Var with the bulk of his forces, and perhaps carry the position there before the French had time to make the necessary dispositions for defending it. Had he adopted this plan, and made arrangements with Admiral Keith and General Abercromby to have the English corps in Minorca landed at the same time on the coast of Italy or France, he would doubtless have been successful. He was not successful because he did not thoroughly appreciate the situation. He did not know how to handle his army. He scattered his forces, and thus dissipated his strength. He spent too much energy at Genoa, and not enough along the Var. His rear guard, which consisted of the thirty-five thousand soldiers under General Kaim in Piedmont, and of twenty thousand scattered throughout Italy, was unnecessarily large, and yet was so divided, subdivided, and dispersed that it was weak at all points. In short, Melas committed many errors.
