Alexander and Napoleon talked on their own for almost two hours during their first meeting on 25 June. Both men were experts in flattery and seduction, and each was intent on winning the other’s sympathy and goodwill. No doubt many ideas were floated which neither monarch would readily have committed to paper, let alone enshrined in a treaty. In the older literature, Russian as well as French, it is sometimes said that Alexander was bowled over by Napoleon and that this partly explains the terms of the Franco-Russian treaties. One has to be very careful in taking Alexander’s admiration of Napoleon at face value, however, particularly when he was speaking to French diplomats. The secret instructions he gave to Kurakin and Lobanov after he had held a number of discussions with the French emperor were rooted in a coolly realistic grasp of the interests, weaknesses and strengths of both Russia and Napoleon.58
In the end Alexander got most of what he wanted in the treaties agreed at Tilsit. Above all, he gained a peace which would be more than a temporary truce, without paying the vanquished side’s usual price of territorial concessions and a war indemnity.59 Apart from this, his overriding concern was to save Prussia, both out of a sense of loyalty to the Prussian king and queen, and because Russia wanted Prussia as an ally against further French expansion eastwards. To achieve this goal Alexander would have to pay a high price. The French now occupied the whole of Prussia and there was no chance that the Russian army could regain it. Napoleon would have preferred to partition Prussia, leaving its eastern – largely Polish – territories to Alexander and distributing the rest of the kingdom among his German clients.
Prussia’s survival was therefore a victory for Russian diplomacy, though an equivocal one. Prussia lost half her territory and population. Her Polish provinces became a new small state, the so-called Duchy of Warsaw. Its ruler was to be the King of Saxony, whose ancestors had been kings of Poland for much of the eighteenth century. The new duchy would be totally obedient to Napoleon and was potentially very dangerous for Russia, both as a base for a future invasion across the empire’s western border and as a source of hope for all Poles who dreamed of the restoration of the Polish kingdom in all its former territories. Forced to reduce its army and pay a vast war indemnity, the newly truncated Prussia was too vulnerable to Napoleon’s power to act as a defensive barrier for Russia, as became clear in 1811–12. Nevertheless, Alexander’s insistence on preserving Prussia was to prove hugely important in 1813, when the Prussians played a vital role in Napoleon’s overthrow.
The main price paid by Russia for Prussia’s survival was agreeing to join Napoleon’s war with Britain. Above all, this meant adherence to Napoleon’s Continental System and therefore the exclusion of British ships and goods from Russian ports. By the terms of the Treaty of Tilsit the Russians were also bound to impose the Continental System on the Swedes, if necessary by war. In June 1807 Alexander was angry at Britain’s failure to support the Russian war effort but he certainly did not want conflict with London and understood the damage it would do to the economy and the state’s finances. He believed, however, that at this moment Russia had no room for manoeuvre between Britain and France, and that subordinating Russia’s economic interests to Napoleon’s overriding concern – in other words blockading British trade – was the only way to ensure an acceptable peace. The emperor comforted himself with the hope that if British trade was excluded from the continent and Napoleon’s terms were moderate, then London would probably make peace. A compromise peace which checked both British expansion outside Europe and French advances on the continent would of course serve Russia’s interests perfectly. Alexander could take more realistic comfort from the fact that the Tilsit treaties did not bind Russia to military action against Britain and that a successful war with Sweden might allow the annexation of Finland, and thereby make Petersburg much more secure against any future Swedish attack.60
