the reserve squadrons, new recruits and remounts arrived in the regiments from Russia and the training and exercising of the men and the horses lasted from morning until night: it was a very hectic, brisk but cheerful business…the same happened in the infantry and artillery…Our efforts paid off because at the end of the armistice the Russian army was in better condition than at the beginning of the war: fully up to strength, well-equipped, healthy, full of courage and enthusiasm for battle, and with a mass of experienced and tested generals, officers and soldiers in numbers it had never previously possessed.66
The Russian reinforcements moving westwards in the spring and summer filled not just the Field Army but also the allied strategic reserve, in other words the so-called Army of Poland which Alexander ordered General Bennigsen to form in early June.67
Bennigsen’s four infantry divisions had been blockading the fortresses of Modlin and Zamosc in the spring. Some of their units had also been performing an internal security role in Poland. At one point their combined strength was less than 8,000 men. By the end of the armistice, however, just these four divisions were 27,000 strong. In September Bennigsen’s army, which included Count Petr Tolstoy’s militia corps, advanced through Silesia to join the Field Army.68But Bennigsen’s army could not just set off to Saxony, uncovering the French garrisons besieged in Modlin and Zamosc and leaving the Duchy of Warsaw denuded of troops. When the autumn campaign began, Napoleon was poised in Silesia, within jumping distance of the Polish border. Many Poles awaited his arrival with impatience. If he advanced through Silesia, his fortresses at Danzig, Modlin and Zamosc would become very important. When Alexander ordered Bennigsen forward, he therefore instructed Dmitrii Lobanov-Rostovsky’s Reserve Army to move across the Duchy of Warsaw and take over his role of blockading Modlin and Zamosc, watching Warsaw and Lublin, and overawing the Polish population. At the same time Lobanov was to continue with his troops’ training and to prepare to dispatch further reinforcements to the Field Army.69
In the last months of the war the Reserve Army played a crucial and successful role in Alexander’s strategy. By deploying Lobanov’s men across the Duchy of Warsaw the emperor had released Bennigsen’s army to make what proved to be a major contribution to the autumn 1813 campaign. The Reserve Army’s blockade of Modlin and Zamosc led to the fall of both these fortresses in the winter of 1813. Throughout this period the Reserve Army’s reinforcements continued to flow to the Field Army in Germany and France. At the end of the war, strengthened by troops released by the fall of Danzig and by the first wave of recruits from the 85th recruit levy, the Reserve Army was at unprecedented strength, with more than 7,000 officers and 325,000 men on its rolls. As always, paper strengths did not accurately reflect the numbers actually present in the ranks. Moreover, many of the soldiers were not yet fully trained or armed, and almost one-quarter were sick. Nevertheless, had the struggle with Napoleon continued there would have been no doubt of Russia’s ability to pull its weight on the battlefield. Also to the point, at a moment when other powers might contest Alexander’s right to Poland, not merely did he have a formidable army in the field to deter them, he could also point to a fresh force of well over a quarter of a million men positioned in the region which he was claiming.70
Europe’s Fate in the Balance
The armistice between Napoleon and the allies was agreed on 4 June. Initially it was set to continue until 20 July. Subsequently, at Austria’s insistence, the allies very unwillingly agreed to extend it until 10 August. During the armistice a peace conference opened in Prague, with Austria mediating between the two sides. Before the conference convened Austria had secretly committed itself to joining the allied cause unless Napoleon agreed to the four minimal Austrian conditions for peace by 10 August. When he failed to do so Austria declared war and the autumn 1813 campaign began. Once this campaign started diplomacy largely took a back seat for three months. The Russians, Prussians and Austrians were agreed on the need to get Napoleon out of Germany and back across the Rhine, and were also agreed that this could only be achieved by military means. Had Napoleon won the initial battles it is possible that rifts would have reopened between the allies, and Austria would have resumed negotiations with Napoleon. In fact, however, diplomacy was mostly confined to consolidating the alliance between the four great powers fighting Napoleon and drawing the smaller German states to their side. Unlike in the spring of 1813 all the decisive moments in the autumn campaign occurred on the battlefield.
