The archduke having ordered retreat after nightfall, both armies camped in their positions. Large forces had already crossed the Danube, including the whole corps of General Lannes. The guard also arrived, which had not yet shared in any engagement during the campaign. Seventy or seventy-five thousand men having reached the left bank, they only waited for Marshal Davout's corps, which had received orders to hasten its march, when the large bridge broke for the third time. Part of the artillery and most of the ammunition-wagons were still on the right bank. When communication was again affected, the fighting was everywhere carried on with fresh fury. Another attack was made on the villages of Aspern and Essling, which had already been reduced to ruins. One after another, Masséna recovered the positions which Molitor was forced on the previous evening to abandon; he also carried the church occupied by the Austrian general, Vacquant. Lannes had received orders, while protecting Essling, to march into the plain, and by a circular movement pierce the enemy's line and cut them in two. This operation was about to be accomplished, and the marshal sent an aide- de-camp to the emperor to ask him to have his rear protected by the guard on his leaving Essling unprotected, when frightful news was brought to Napoleon. The trunks of trees, stones, and rubbish of every kind, brought down by the rapid current of the river, had again broken the cables which held together the boats composing the great bridge, and both parts were carried down the stream, taking with them a squadron of cuirassiers, who were then defiling over. The passage of the troops being stopped, and the ammunition running short, Napoleon ordered Lannes to fall back on the line of the villages and abandon the pursuit of the Austrians, who were just before that hardly pressed everywhere. Whilst the marshal, bitterly disappointed, was effecting this backward movement, the archduke ordered all his artillery to be directed upon him: General St. Hilaire was killed at the head of his division, and whole files of General Oudinot's regiments were shot down--unfortunate lads, so recently enrolled that their officers durst not deploy them before the enemy. It was now midday; Major-General Berthier had just written to Marshal Davout, retained on the opposite bank of the Danube: "The interruption of the bridge has prevented provision-supplies: at ten o'clock we were short of ammunition, and the enemy, perceiving it, marched back upon us. Two hundred guns, to which we cannot reply, have done us much harm. In these circumstances, it is extremely important to repair the bridges and send ammunition and food. Write to the Prince of Ponte Corvo (Bernadotte) not to open a campaign in Bohemia, and to General Lauriston to be ready to join us. See that Daru sends us ambulance-stores and provisions of every kind. As soon as the bridge is ready, or during the night, come and have a consultation with the emperor."
