In 1794, when this had been crushed, the intention of the French government was to take the offensive against the Austro-Sardinians. The first operation was to be the capture of Oneglia. The concentration of large forces in the lower Rhone valley had naturally infringed upon the areas told off for the provisioning of the Armies of the Alps (Kellermann) and of Italy (Dumerbion); indeed, the sullen population could hardly be induced to feed the troops suppressing the revolt, still less the distant frontier armies. Thus the only source of supply was the Riviera of Genoa: "Our connexion with this district is imperilled by the corsairs of Oneglia (a Sardinian town) owing to the cessation of our operations afloat. The army is living from hand to mouth," wrote the younger Robespierre in September 1793. Vessels bearing supplies from Genoa could not avoid the corsairs by taking the open sea, for there the British fleet was supreme. Carnot therefore ordered the Army of Italy to capture Oneglia, and 21,000 men (the rest of the 67,000 effectives were held back for coast defence) began operations in April. The French left moved against the enemy's positions on the main road over the Col di Tenda, the centre towards Ponte di Nava, and the right along the Riviera. All met with success, thanks to Massena's bold handling of the centre column. Not only was Oneglia captured, but also the Col di Tenda. Napoleon Bonaparte served in these affairs on the headquarter staff. Meantime the Army of the Alps had possessed itself of the Little St Bernard and Mont Cenis, and the Republicans were now masters of several routes into Piedmont (May). But the Alpine roads merely led to fortresses, and both Carnot and Bonaparte--Napoleon had by now captivated the younger Robespierre and become the leading spirit in Dumerbion's army--considered that the Army of the Alps should be weakened to the profit of the Army of Italy, and that the time had come to disregard the feeble neutrality of Genoa, and to advance over the Col di Tenda.
