The Archduke Charles, understanding how Ney was prospering in the Tyrol, had given up the design of retreating by that way into Germany, and proceeded through the Carinthian Mountains towards Hungary.

Prince John now followed his brother's example; and, the remains of those two armies thus coalescing in a distant region, the divisions of Ney and Messena came to be at the immediate disposal of Napoleon, who was now concentrating his force for the purpose of attacking Vienna.
While the victorious corps of Ney thus secured his right--Murat, on his left, watched the Austrians who had made their way into Bohemia; and Augereau, who had now advanced at the head of a large reserve from France, remained behind him in Swabia, to guard the passes from the Voralberg, in case of any hostile movement from that mountainous province, and, at the same time, to be ready for action against the Prussians, should that army at length receive orders to take part in the war, and cross the Danube.

Thus guarded, as he judged, against any chance of having his communications intercepted in the rear or flanks, Napoleon himself, with the main body, now moved on the capital of the German Emperor.

Austrian and Russian troops, to the number of 45,000, had been thrown together with the view of relieving Ulm, and advanced considerably for that purpose ere they heard of the treacherous capitulation of Mack.

They now retired again before the movement of Napoleon, halting, indeed, occasionally, and assuming the aspect of determination; but, whenever the outposts met, losing heart, and continuing their progress towards Moravia:--for there, at length, the Czar, with his principal army, had made his appearance; and there, around that standard, every disposable force was now to be rallied.
