Having once reached the fertile valley of the Po, Bonaparte expected to find food and forage there in abundance; but during the march from Villeneuve to Ivrea it was necessary to provide supplies in advance for the army. For this purpose he had collected them at Lake Geneva. He now caused them to be distributed at different points along this route. He also sent money to the monks in charge of the Great St. Bernard Hospital, in order that they should purchase bread, cheese, and wine for the soldiers. At Villeneuve, Martigny, Saint Pierre, and Saint Remy, he established hospitals for the sick and injured. To the foot of the defile at Saint Pierre he sent forward a company of mechanics to dismount the guns and to divide the gun-carriages and caissons into numbered parts for transportation on pack mules. The ammunition too was carried in this way. But the cannon themselves could not be thus transported. For this purpose sledges with rollers had been made, but they were found to be of no use. Finally, the cannon were enclosed within the trunks of trees hollowed out for the purpose. Thus protected, they were dragged across the Alps by the soldiers themselves. A second company of mechanics was ordered to march with the first division and to establish itself at Saint Remy, in order to put together the carriages and caissons, to remount the pieces, and to make the necessary repairs. On the 14th of May Bonaparte was ready to begin the movement. The Army of Reserve numbered forty thousand soldiers and forty cannon; about four thousand were cavalry. Four corps of the army, numbering thirty-five thousand men, commanded by Murat, Victor, Duhesme, and Lannes, had taken position from Villeneuve to Saint Pierre. A fifth corps, of five thousand men, commanded by Chabran, was in Savoy at the foot of the Little St. Bernard Pass. Bonaparte himself was at Martigny, at which place he issued the orders for the movement. He had sent Berthier forward to receive the divisions on the Italian side of the Alps.
