There were also military reasons why the war dragged on. In the field the Ottoman army was hopeless. To win battles in this era required infantry trained to deliver rapid volleys and to move in formation across the battlefield. The troops must be able to shift between column, line and square according to circumstances and to do so rapidly and in good order. The infantry needed to be supported by mobile artillery and by cavalry trained to charge home in massed formation to exploit any wavering by the enemy. Though all this sounds simple, amidst the terrors of the battlefield it was anything but. To achieve this an army required good training, a strong core of veterans, and experienced officers and NCOs. Behind the army there had to stand a state and a society capable of providing reliable officers and of paying the large sums needed for men, arms, food and equipment. The main European armies achieved this and so did the British in India. The Ottomans did not, for many reasons, of which inadequate financial resources was probably the most important. By the 1770s their untrained and ill-disciplined levies could seldom stand up to the Russians in open battle.
In siege warfare the Ottomans remained formidable, however. Napoleon discovered this in his Egyptian campaign. Having scattered Muslim armies on the battlefield without difficulty, he came to a halt before the fortress of Acre. The Balkans were the Ottomans’ main strategic theatre. Fortresses here were far stronger than Acre. They were generally defended, often from house to house, not just with skill but also very great tenacity. Perhaps the only comparison in the Napoleonic Wars was the siege of Saragossa, which the French finally took after immense bloodshed and resistance. The terrain of the Balkans helps to explain why siege warfare often prevailed in this theatre. Unlike in western Europe, there were few good roads and population densities were low. A good fortress could block the only viable invasion route into a district. The Ottomans were also experts at ravaging the countryside, and at raids and ambushes. An army which sat down to besiege a fortress would find its supply columns raided and its foraging parties forced to scatter over great distances. In 1806–12 the Russians faced all these problems. Pressed by Alexander to end the war, on occasion the Russian commanders attempted premature storming of fortresses and suffered heavy casualties. At Rushchuk in 1810, for example, 8,000 men of a force of barely 20,000 became casualties in an unsuccessful attempt to storm the town.47
Finally, in the winter of 1811–12 the crafty new Russian commander-in-chief, Mikhail Kutuzov, cut off the main Ottoman army as it attempted to manoeuvre against him, and forced it to surrender. In so doing he made one of his greatest contributions to the 1812 campaign before it had begun. With his main armies lost, his treasury empty and intrigue rife in Constantinople, the sultan agreed to peace, which was signed in June 1812. The peace came too late to allow the Army of the Danube to be deployed northwards to face Napoleon’s invasion, but soon enough for the troops to reach Belorussia by the autumn and pose a huge threat to Napoleon’s communications and his retreating army.
At the other, northern end of the Russian line the obvious danger was that, with French power resurgent, Sweden would revert to its traditional role as a French client. When Marshal Jean-Baptiste Bernadotte was elected as heir to the Swedish throne in August 1810 this danger appeared to be confirmed. Since he was Joseph Bonaparte’s brother-in-law as well as Napoleon’s marshal, on the surface Bernadotte appeared likely to prove a reliable French client. In fact, he had stored up a good deal of resentment against Napoleon and moved quickly to reassure Alexander I about his peaceful intentions regarding Russia. It helped greatly that Aleksandr Chernyshev had established a close relationship with Bernadotte before any question of the Swedish throne came up and was able to act as a trusted intermediary between him and Alexander both in Paris immediately after his election and in an important special mission which he undertook to Stockholm in the winter of 1810. Even before Bernadotte’s final selection as Swedish crown prince, Chernyshev was able to reassure Petersburg that he had got to know the marshal well, that Bernadotte was well disposed towards Russia and that he was certainly no admirer of Napoleon.48
