KUTUZOV had, on the 1st of November, received from one of his spies information that showed the army he commanded to be in an almost hopeless position. The spy reported that the French, after crossing the bridge at Vienna, were moving in immense force on Kutuzov’s line of communications with the reinforcements marching from Russia. If Kutuzov were to determine to remain at Krems, Napoleon’s army of a hundred and fifty thousand men would cut him off from all communications, and would surround his exhausted army of forty thousand, and he would find himself in the position of Mack before Ulm. If Kutuzov decided to leave the road leading to a junction with the Russian reinforcements, he would have to make his way with no road through unknown country to the mountains of Bohemia, pursued by the cream of the enemy’s forces, and to give up all hope of effecting a junction with Buxhevden. If Kutuzov decided to march by the road from Krems to Olm?tz to join the forces from Russia he ran the risk of finding the French, who had crossed the Vienna bridge, in advance of him on this road, and so being forced to give battle on the march, encumbered with all his stores and transport, with an enemy three times as numerous and hemming him in on both sides. Kutuzov chose the last course.
The French, after crossing the river, had, as the spy reported, set off at a quick march toward Znaim, which lay on Kutuzov’s line of routes more than a hundred versts in front of him. To reach Znaim before the French offered the best hopes of saving the army. To allow the French to get to Znaim before him would mean exposing the whole army to a disgrace like that of the Austrians at Ulm, or to complete destruction. But to arrive there before the French with the whole army was impossible. The road of the French army from Vienna to Znaim was shorter and better than the Russians’ road from Krems to Znaim.
On the night of receiving the news Kutuzov sent Bagration’s advance guard of four thousand soldiers to the right over the mountains from the Krems-Znaim road to the Vienna and Znaim road. Bagration was to make a forced march, to halt facing towards Vienna and with his back to Znaim, and if he succeeded in getting on the road in advance of the French, he was to delay them as long as he could. Kutuzov himself with all the transport was making straight for Znaim.
