Russia Against Napoleon_ The True Story of the Campaigns of War and Peace - Dominic Lieven [311]
On 22 March Schwarzenberg and Alexander did not know in which direction Napoleon was heading. Petr Volkonsky wrote to Gneisenau on 22 March that Napoleon had masked his movements by leaving large cavalry screens behind him. The allies intended to follow hot on his heels. If the enemy attacked the Army of Silesia then on this occasion the main army would be right on his tail and would strike his rear. If he took any other direction, the two armies would unite and then advance against him and seek battle. That very evening Blücher discovered exactly where the enemy was heading because his Cossacks had captured a French courier with a letter from Napoleon to Marie-Louise saying that he was intending to attack the allies’ communications and thereby draw them well away from Paris.20
A copy of the letter was immediately sent to the main army headquarters where its implications were discussed in a council of war held in Pougy on the afternoon of 23 March. Of Alexander’s closest Russian military advisers only Petr Volkonsky was in Pougy at the time, and he never spoke up publicly in such meetings. The most basic point, however, was that by the time the allied armies could be turned round Napoleon would have two days’ start on them. Nothing could now stop him from getting into the allied rear. Any attempt to race back to protect allied bases would put tremendous strains on army morale and discipline, not least because the troops would be marching into areas already ravaged by war, where they would find it very difficult to feed themselves. For the moment therefore the allied leaders stuck to their existing plan to link up with Blücher and then advance to meet the enemy and give battle. Meanwhile urgent orders went out to town commandants and commanders of troops in the rear to get as many supplies, transport columns and reinforcements as possible under protection or away from the main roads. The ever-nervous provost-general, Oertel, had previously been chided for over-reacting to imagined threats to the Russian lines of communication. Now urgent orders went out to him from Barclay to take emergency measures to preserve Russian bases, supplies and treasuries. Oertel did well on this occasion and reported his arrangements to Barclay, a fellow Balt, in Latvian, a language which the commander-in-chief understood. If the orders were intercepted, it would be a very unusual Frenchman who could decipher them.21
On the evening of 23 March Schwarzenberg, Alexander, Frederick William and their staffs set off from Pougy to Sompuis where they arrived early in the morning of the next day. On the way they were given more enemy dispatches captured by the Russian cavalry. These told of the low morale of Napoleon’s troops and their generals, and also revealed that Paris’s depots and arsenals were empty. Most important was a letter to Napoleon from his police chief Savary, who wrote that he could not answer for the capital’s loyalty if the allied armies approached. That same night news arrived from the south that Bordeaux had gone over to the Bourbons and that the city had been occupied by Wellington. Nevertheless when Schwarzenberg and Frederick William left Sompuis on the morning of 24 March the allied plan was still to unite their two armies and then go in search of Napoleon.
Not long afterwards, at approximately ten o’clock, Alexander summoned Barclay, Diebitsch and Toll, showed them the intercepted letters and the troops’ current positions on the map, and asked for their advice about the best course of action. He put two options to them: either the allies could pursue Napoleon or they could march on Paris. It may be that Alexander had already talked to Volkonsky, who had spoken up in private for moving on Paris. Barclay on the contrary was a cautious and not very imaginative
