Eugene, having reconnoitred the position of the French, considered the passage impossible. He therefore withdrew the bridge, and broke up his camp during the night.
It was by this manœuvre, also, that, in the campaign of 1809, the Archduke Charles compelled the French to reoccupy the isle of Lobau, after having debouched on the left bank of the Danube. The march of the Archduke Charles was wholly concentric. He menaced Grosaspern with his right, Esling with his centre, and Enzersdorf with his left.
His army, with both wings resting on the Danube, formed a semicircle around Esling. Napoleon immediately attacked and broke the centre of the Austrians; but after having forced their first line, he found himself arrested by the reserves. In the meantime, the bridges upon the Danube had been destroyed, and several of his corps, with their parks of artillery, were still on the right bank. This disappointment, joined to the favorable position of the Austrians, decided Napoleon to re-enter the isle of Lobau, where he had previously constructed a line of field-works, so as to give it all the advantages of a well entrenched camp.
