Russia Against Napoleon_ The True Story of the Campaigns of War and Peace - Dominic Lieven [92]
In a retreat of this sort a strong cavalry arm was essential. Barclay was weakened by the fact that Napoleon’s advance had cut off General Matvei Platov’s independent Cossack detachment from First Army and forced it to move southwards to join up with Bagration. Platov’s force was made up of nine Cossack regiments, all but two of them from the Don region. It also included four ‘native’ regiments of irregular cavalry, of which two were Crimean Tatar, one was Kalmyk and one was Bashkir.
No one needed to fear for the safety of Platov’s regiments. Napoleon’s whole army could have chased these Cossacks all year without the least chance of catching them. But the temporary loss of almost all its irregular cavalry put Barclay’s regular cavalry regiments under some strain. Fedor Uvarov reported that in the absence of the Cossacks he had been forced to use regular line and even Guards cavalry regiments for outpost duty. Not merely did this exhaust their horses, it also involved them in work for which they had often not been fully trained. One result of this was that Uvarov could not harass the enemy or pick up anything like the normal number of prisoners, who were important as a source of intelligence about the enemy’s size and movements.18
Even without the Cossacks, however, the Russian cavalry usually came out on top in its skirmishes with the French. The French cavalry had very little success in impeding or embarrassing Barclay’s men in their planned retreat to Drissa. In other ways, too, the Russian high command had reason to be satisfied. Napoleon had yearned for a decisive battle in the first days of the war. His overriding strategic purpose was not the conquest of territory but the destruction of the Russian army. Correctly, he believed that if he could annihilate the armies of Barclay and Bagration in a second Austerlitz then Alexander would have little option but to make peace on French terms. The Russians had encouraged his hopes of an early decisive battle by ‘turning’ a key French agent in Lithuania and passing disinformation through him that they intended to fight for Vilna. Caulaincourt recalls that ‘Napoleon was amazed that they had yielded Vilna without a struggle, and had taken their decision in time to escape him. It was truly heartbreaking for him to have to give up all hope of a great battle before Vilna.’19
The Russian high command also learned quickly that Napoleon’s army was paying a heavy price for his determination to press the retreating enemy and force it to battle. Many of Napoleon’s men and, more importantly, his horses had been poorly fed in the weeks before the invasion. In all circumstances his huge army, concentrated in anticipation of an early decisive battle, would have found it impossible to feed itself adequately in impoverished Lithuania. Speeding forward in an attempt to force Barclay to battle across terrain eaten out and scorched by the Russians made matters worse. Torrential rain completed a picture of misery. After only two weeks of campaigning Napoleon wrote to his war minister in Paris that there was no point trying to raise new cavalry regiments since all the horses available in France and Germany would barely suffice to remount his existing cavalry and make up for the enormous losses he had already suffered in Russia. Deserters and prisoners of war informed the Russians of hunger and disease in the French ranks, and above all of the devastating loss of horses. So too did the military intelligence officers who were sent on supposedly diplomatic missions to French headquarters under flag of truce.20
Much the best-known mission was General Balashev’s visit to Napoleon’s headquarters immediately
