Ever since 1812 historians have puzzled as to why Napoleon acted in this fashion. The most plausible explanation is that he did not want to dislodge the Russians but rather to destroy their army in a battle for the city. Perhaps he believed that if he gave them the chance to fight for Smolensk they would not dare simply to abandon so famous a Russian city. If so, Napoleon’s calculation proved wrong, because after a day’s ferocious fighting on 17 August Barclay once again ordered his army to retreat. It is worth remembering, however, that Barclay did this against the strong and universal opposition of Bagration and all of First Army’s senior generals. He faced furious accusations of incompetence and even treason. Predictably, the Grand Duke Constantine’s was the loudest and most hysterical voice, screaming out within earshot of junior officers and men that ‘it isn’t Russian blood that flows in those who command us’. Barclay de Tolly also knew that his decision to retreat would anger Alexander and probably wreck his standing with the emperor. It took great resolution, unselfishness and moral courage for Barclay to act in the way he did. Perhaps Napoleon cannot be blamed for failing to predict this.47
The Russian generals’ opposition to abandoning Smolensk was all the stronger because they had defended it successfully against great odds and with heavy losses throughout 17 August. In the battle for Smolensk, 11,000 Russians died or were wounded. Nevertheless, nowhere had the French broken through the walls and into the city. Though Smolensk’s defences were medieval they did sometimes provide good cover for Russian artillery and skirmishers. In some cases, too, attacking French columns could be hit by Russian batteries firing from across the river Dnieper.
The Russian infantry fought with great courage and grim determination. Ivan Liprandi was a senior staff officer in Dmitrii Dokhturov’s Sixth Corps. His accounts of the 1812 campaign are among the most thoughtful and accurate from the Russian side. He remembered that at Smolensk it was difficult for the officers to stop their men from launching wasteful counter-attacks against the French at every opportunity. Volunteers for dangerous tasks were plentiful. Many soldiers refused to go off to the rear to have their wounds seen to. The sight of the city in flames and of the wretched remnants of the civilian population was an additional incentive to fight to the death. So too was the sense, absorbed with their mother’s milk, that Smolensk was from ancient times Orthodox Russia’s citadel against invasion from the ‘Latin’ West. In previous centuries the city had at times been a prize contested between the Russians and the Poles. One officer remembered that, although the soldiers sometimes took French prisoners, on 17 August they always killed the Poles.48
The Russian troops in the city had been commanded by Dmitrii Dokhturov and on the night of 18 August he very unwillingly obeyed Barclay’s order to evacuate Smolensk and pull back to the city’s northern suburbs across the river Dnieper. That day Barclay allowed his exhausted soldiers a rest. On the night of 18–19 August he ordered them to retreat towards the main road which led back through Solovevo and Dorogobuzh into the Great Russian heartland and ultimately to Moscow.
The initial stages of this retreat presented serious difficulties. After it left Smolensk the main road to Moscow passed along the east bank of the Dnieper in full view and easy artillery range of the west bank. The river was also easily fordable in a number of places during the summer. Barclay did not want his retreating column, spread out as it would be for miles, to offer a perfect opportunity for the French to attack it on the march. So he decided to move his men in the night of 18–19 August down side roads which would lead them out onto the main Moscow road at a safe distance from Smolensk and the French. First Army would be divided into two halves. Dmitrii Dokhturov would lead the smaller half of the army on the longer detour which would take a night and a day before ultimately bringing them out on the Moscow road, not far from Solovevo. This part of the operation went without a hitch but it did mean that when disaster threatened the other half of First Army on 19 August Dokhturov was far away and unable to help.
