Despite this criticism, Napoleon reinforced Oudinot by all the infantry and artillery of Gouvion Saint-Cyr’s Sixth (Bavarian) Corps. Marching in the wake of the first echelon of Napoleon’s army, Sixth Corps was 25,000-strong when it crossed the Neman but had only 13,000 men left by the time they joined Oudinot at Polotsk just five weeks later. It is true that the Bavarian cavalry had been detached to join Napoleon’s main body, but most of the losses were due to sickness, straggling and desertion. During this period the Bavarians had not fired a shot in anger.
Although Wittgenstein knew that with the arrival of Saint-Cyr’s corps he was heavily outnumbered, he was determined to retain the initiative and impose his will on the enemy. With this goal in mind he attacked the joint forces of Oudinot and Saint-Cyr at Polotsk on 17 August. Unfortunately for Wittgenstein, although on the battle’s first day he succeeded in pushing the French back into the town of Polotsk, Oudinot himself was wounded and command passed to the far more competent Saint-Cyr. The next day the new French commander concentrated much of his artillery and two fresh infantry divisions for a counter-attack on the Russian centre. With a sleight of hand rather familiar in descriptions of battles at this time, Saint-Cyr claimed that his army was substantially outnumbered. He wrote in his memoirs that one-quarter of the 31,000-strong French force was absent ‘foraging’, whereas Wittgenstein had more than 30,000 soldiers to hand. In reality, as Wittgenstein reported to Alexander, constant battles, combined with the need to need to keep an eye on MacDonald, meant that his available strike force was reduced to barely 18,000 men.8
Surprise combined with overwhelming numbers meant that the Russians were forced to retreat but they did so with great steadiness and courage. The Estland Regiment, for example, had been formed in 1811 from the soldiers of garrison units. The battle of Polotsk was its first serious action. As part of Major-General Gothard Helfreich’s 14th Division, the men of the Estland Regiment stood right in the path of the French counter-attack. Despite this and despite losing fourteen officers and more than 400 men, the Estland Regiment held off repeated enemy attacks during 18 August, skirmished effectively in the woods, and finally won their way to safety. The regiment’s commanding officer, Colonel Karl Ulrikhin, was wounded twice and subsequently forced to retire from the army as a result. But he stayed with his men throughout the retreat, leading a number of counter-attacks to keep the enemy at a safe distance. Forty-three men of the Estland Regiment won military medals for their performance on 18 July and the regiment itself was awarded a standard to mark its exploits.9
One might perhaps take a regimental history’s account of its own soldiers’ courage with a pinch of salt, but in this case the Russian story is supported by Saint-Cyr himself, who wrote that
the Russians showed in this battle a sustained courage and an individual boldness of which one finds very few equivalents in the armies of other nations. Surprised, fragmented, with their battalions isolated as much as actually attacked (for we had penetrated through their lines), they nevertheless were not disconcerted and continued to fight as they retreated, which they did very slowly, facing about in all directions with a courage and a steadiness which is, I repeat, particular to the soldiers of this nation. They performed prodigies of valour but they could not beat back the simultaneous attack of four concentrated and ordered divisions.10
Technically the battle of Polotsk was a defeat for Wittgenstein but in fact it helped him to achieve his strategic goal, which was so to weaken and impress the enemy that they would refrain from advancing down the roads to Pskov, Novgorod and Petersburg. After the battle, Wittgenstein fell back roughly 40 kilometres to a fortified position near Sivoshin, where the French left him in peace for the next two months. During that time stalemate reigned in the north-west, with the war degenerating into raids and a competition between the two armies to feed themselves and rebuild their strength. To an extent, what happened next was precisely what Pfühl had planned at Drissa. Weakened by the advance across the western borderlands, Saint-Cyr lacked the numbers either to attack Wittgenstein behind his entrenchments or to move past his flank. Pinned down in a static position in a poor and devastated countryside, sickness and hunger melted away the French army.
