After abandoning Drissa and bidding farewell to Alexander, Barclay de Tolly was in fact planning to make a stand in front of Vitebsk. Partly this was to sustain his troops’ morale. When the army had reached Drissa the soldiers had been served up a bombastic proclamation promising that the time for retreating was over and that Russian courage would bury Napoleon and his army on the banks of the Dvina. When a few days later the retreat was renewed there was inevitable muttering. Ivan Radozhitsky, a young artillery officer in Fourth Corps, overheard grumbling among his gunners at the ‘unheard-of’ retreat of Russian troops and the abandonment of huge swaths of the empire without a fight. ‘Obviously the villain [i.e. Napoleon] must be very strong: just look at how much we are giving him for free, almost the whole of old Poland.’28
Barclay’s main reason for risking a battle at Vitebsk, however, was to distract Napoleon’s attention and allow Bagration to advance through Mogilev and unite with First Army. Barclay’s troops arrived at Vitebsk on 23 July. To gain time for them to gather their breath and for Bagration to arrive he detached Count Aleksandr Ostermann-Tolstoy’s Fourth Corps down the main road leading into Vitebsk from the west in order to slow down Napoleon’s advancing columns. On 25 July at Ostrovno, roughly 20 kilometres from Vitebsk, there occurred the first major clash between Napoleon’s forces and First Army.
Aleksandr Ostermann-Tolstoy was immensely wealthy and had some of the eccentricities worthy of a Russian magnate of this era. Despite his name, he was a purely Russian type: adding the prefix ‘Ostermann’ to his own proud surname of Tolstoy had been an unwilling concession to rich bachelor uncles who had left him their great fortunes. Ostermann-Tolstoy was a handsome man, thin-faced and with an eagle’s nose. He looked the pensive, Romantic hero. On his estate in Kaluga province Tolstoy lived with a pet bear decked out in fantastic dress. More modest when on campaign, he nevertheless liked when possible to be accompanied by his pet eagle and his white crow. In some ways Ostermann-Tolstoy was an admirable man. He was a great patriot, who had loathed what he saw as Russia’s humiliation at Tilsit. Well educated, fluent in French and German and a lover of Russian literature, he was enormously and inspiringly brave, even by the very high standard of the Russian army. He was also careful of his men’s food, health and welfare. He shared their love for buckwheat
Fourth Corps fought the battle at Ostrovno in a manner that rather reflected Ostermann-Tolstoy’s character, though to be fair it also reflected the inexperience of many of his units and the Russian soldiers’ longing finally to get to grips with the enemy. Barclay sent forward his aide-de-camp, Vladimir Löwenstern, to keep an eye on Ostermann-Tolstoy. Subsequently Löwenstern recalled that the corps commander showed exceptional courage but also exposed his troops to unnecessary losses. The same point was made by Gavril Meshetich, a young artillery officer serving in the Second Heavy Battery of Fourth Corps.
According to Meshetich, Ostermann-Tolstoy failed to take proper precautions despite the fact that he had been warned that the French were nearby. As a result his advance guard was ambushed and lost six guns. Subsequently he did not use the cover available on either side of the main road to shelter his infantry from enemy artillery fire. He also attempted to drive back enemy skirmishers with a massed bayonet charge, a tactic much used by the Russians in 1805 and which generally proved both costly and ineffective. Ostermann-Tolstoy could not, however, be blamed for the small-scale debacle which occurred on his left flank where the Ingermanland Dragoon Regiment had been posted in a wood to keep an eye on the French. At last given the opportunity to have a go at the enemy, the Russian dragoons stormed out of the forest, smashed through the nearest enemy cavalry and were then overwhelmed by superior French numbers, losing 30 per cent of their men. One result of these losses was that the regiment was kept out of the front line and relegated to military police duties for much of the rest of 1812. To fill the shoes of the officers lost at Ostrovno, five non-noble NCOs were promoted, one of the earliest examples of what was to become a common occurrence in 1812–14.30
