This was of little comfort to Russia, whose armies were fleeing before the triumphant Grande Armée, and who had to face up to the possibility of other enemies seizing the opportunity to recover lost lands. One such was Turkey, with whom Russia made a hurried peace. Another was Sweden, from which she had taken Finland only three years before, and which would almost certainly wish to recover it. Had Sweden invaded at that moment, Russia’s defences would probably have collapsed entirely.
Tsar Alexander opened negotiations with Bernadotte and arranged a personal meeting, at Åbo. In the course of the discussions Alexander managed to convince Bernadotte to let Russia keep Finland, in return for which he would help Sweden take Norway from Denmark, an ally of France. He also undertook to persuade Britain to give Sweden one of the colonies she had taken from France. He did everything to charm the renegade French Marshal, and in order to seal their entente he threw out another piece of bait, the prospect of Bernadotte’s ascending the throne of France once Napoleon had been defeated.
Shortly after, Castlereagh opened negotiations with Sweden, which culminated in the Treaty of Stockholm, signed on 3 March 1813. The terms were extraordinarily generous to Sweden. Britain undertook to assist her in taking possession of Norway, with military support if the King of Denmark were to prove recalcitrant, to cede her the former French West Indian island of Guadeloupe, and to pay her the sum of £1 million, in return for which Sweden promised to field 30,000 men against Napoleon.7
News of the signature of the Treaty of Kalisch between Russia and Prussia on 1 March 1813 was greeted with joy in London, but Castlereagh was less than thrilled. Britain had not been consulted on the subject of the projected treaty, which suggested that Russia felt she could act independently of her British ally. It also meant that Castlereagh had no idea what secret clauses the treaty might contain. And the fact that Britain, Russia, Sweden and Prussia were now aligned against France did not in itself amount to a coalition. Even were that so, experience taught that coalitions were vulnerable to the slightest reversal of fortune.
The first coalition against France had come together in 1793. It combined Austria, Russia, Prussia, Spain and a number of lesser powers. This formidable alliance proved ineffectual when faced with the élan of France’s revolutionary armies, and it fell apart in 1796. A second coalition, consisting of Britain, Russia, Austria and Turkey, was cobbled together in 1799, but this disintegrated after the French victories of Marengo and Hohenlinden. A third, painstakingly constructed by Castlereagh’s mentor William Pitt in 1805, combined Austria, Russia, Sweden and Prussia with Britain, but this too was shattered by Napoleon’s victories at Austerlitz, Jena and Friedland. The one allied victory, Trafalgar, had failed to affect the outcome.
By 1807, when he signed a far-reaching alliance with Russia, Napoleon controlled virtually the whole of Continental Europe, making it impossible for Britain to play any part in its affairs, except in Portugal, where a small expeditionary force hung on precariously. Although she was supreme on the seas, much of the advantage this gave her was negated by a tariff war with France. Napoleon’s Continental System excluded the British from trading with any part of Europe, and eventually led to the outbreak of war between Britain and the United States of America.
As he contemplated the possibility of the birth of a new coalition in the spring of 1813, Castlereagh was acutely aware of both the need to direct it and the lack of means at his disposal. Britain’s military capabilities were already stretched to breaking point by the double commitment of fighting one war with France in Spain and another with the United States of America across the Atlantic, so all he could contribute was money. And money could not buy sufficient influence to impose unity on a diverse set of allies.
Britain had always been concerned first and foremost with naval matters, and it was only when the armies of Revolutionary France advanced into the Austrian Netherlands in 1792 and threatened to take the estuary of the river Scheldt that a hitherto indifferent Britain felt impelled to go to war. The Scheldt estuary and the port of Antwerp had traditionally been viewed in Whitehall as the ideal base for an invasion of England, and the very thought of their falling into French hands was the stuff of nightmare. Provided the entire Netherlands could be kept in friendly or neutral hands, Britain had no interest in what form of government France saddled herself with. This divided Britain from her allies in the first coalition, who saw it as more of a monarchical crusade against revolution. In time, Britain’s views on the subject of France converged with those of her Continental allies, yet significant differences remained. And any coalition was vulnerable to underlying resentments and a distrust based on mutual incomprehension of each other’s strategic imperatives.
As an island and a sea power with no land army to speak of, Britain could only participate significantly in the fighting on the Continent through subsidies, which her allies used in order to raise and equip armies. Her naval victories over the French, even when they were on the scale of the battles of the Nile or Trafalgar, made no palpable difference to the situation on the European mainland. It therefore appeared that Britain was not pulling her weight or making the same sacrifices as her allies – the subsidies she contributed were, in their view, more than covered by the wealth of the French and Dutch colonies that fell into British hands and the riches confiscated on the high seas by her navy.
For a Continental power, a battle won brought no such advantages, while a battle lost often entailed the ravaging of its own territory and the necessity to sue for peace on any terms. The British, safe behind their watery defences, could not understand this predicament. They had no experience of foreign invasion and occupation, and bemoaned their allies’ lamentable tendency to sue for peace at the first setback. They tended to look upon any state that had been forced to do so as an enemy. Having no first-hand experience of fighting against Napoleon, the British were inclined to attribute his victories to the failings of their allies’ armies and the pusillanimity of their governments. This seemed to be borne out when the one Continental power as strategically invulnerable as Britain, Russia, submitted to Napoleon in 1807.
In the event, Russia had only done so because her Austrian ally had been defeated and forced to sue for peace, her Prussian ally had been shattered and reduced to nothing, and her British one was incapable of sending a single regiment to assist her. But Castlereagh, like Pitt before him, could not imagine what it was like to be left isolated facing a victorious Napoleon across a corpse-strewn battlefield. All he knew was that coalitions tended to fall apart, and he ascribed this principally to their not having a clearly defined purpose and a mechanism to ensure that all parties stuck to it until it was achieved.
As he watched events unfold on the Continent in the spring of 1813, Castlereagh determined that he must somehow ensure that the allies in this incipient coalition would make war together and peace together, on terms agreed mutually and properly defined. That was not going to be easy.
Britain’s diplomats had been excluded from a large part of the Continent for the past fifteen years and from the rest of it for the past three or four, so there was a dearth of knowledge in London as to what was going on in various countries and who the important players were. There was a corresponding lack of experienced diplomats, just at the moment when Castlereagh needed them. To Russia he had sent Lord Cathcart, an old soldier with scant diplomatic experience. To Prussian headquarters he now despatched his own half-brother, Sir Charles Stewart, another soldier, and not a particularly distinguished one at that. Stewart was thirty-five years old. He had served on Wellington’s staff in the peninsula, where he had displayed impetuous courage but none of the qualities requisite for a command – ‘A most gallant fellow, but perfectly mad,’ in the words of a brother officer. Stewart would probably have approved of that description. ‘My schemes are those of a Hussar at the Outposts,’ he wrote to the painter Thomas Lawrence before taking up his first diplomatic post. ‘Very short, very decided, and very prompt.’8
Castlereagh’s instructions to these two dealt mainly with the extent of the subsidies which Britain was to contribute to the allied cause. But they also sketched out the basis of a final settlement
