Adam Zamoyski - Rites of Peace - The Fall of Napoleon and the Congress of Vienna

But it would be wrong to see Castlereagh’s change of heart as a self-interested volte-face . It stemmed from his acceptance of Pitt’s conviction that illegitimate revolution could never bring the kind of stability necessary for the development of civil society, and was reinforced by the common sense that came with age. Nor did it come without a struggle. There can be little doubt that Castlereagh worked hard at reining in the impetuous side of his nature, which occasionally revealed itself in heated words and, most spectacularly, in his challenging George Canning to a duel in 1809 over their political differences.

By his mid-thirties he had become a paragon of middle-class values. He was happily married, abstemious and ordered in his habits, drinking little and rising early, never happier than when he could leave London to spend time on his farm at Cray in Kent, where he indulged his love of gardening and animal husbandry. He enjoyed the company of children. He was kind to servants and generous to the poor. He was industrious and conscientious in his work. He took his ease with books and indulged himself with music, which he loved, playing the cello and singing whenever the opportunity presented itself.

His tenure at the War Office, which came to an end in 1809, had not been deemed a success. His one achievement was to bend rules in order to have General Arthur Wellesley appointed to command the expeditionary force being sent to the Iberian peninsula in 1808. But its benefits did not become apparent until a few years later when, as Lord Wellington, Wellesley won the first decisive British victories over the French. In 1812 Castlereagh became Foreign Secretary, a post altogether better suited to his talents.

Castlereagh was a very able man. He could grasp the complexities of a problem quickly, along with its possible ramifications, and he could write it up in clear, elegant prose. But he was not an original thinker. He knew nothing of European affairs, and lacked the imagination to see what was happening on the Continent. He had imbibed his views on foreign policy from his hero Pitt, and he would remain faithful to them.

When he took over at the Foreign Office Britain was entirely isolated, with no influence on the European mainland. His first actions were therefore aimed at finding allies on the Continent and building up a coalition against Napoleon. Napoleon’s invasion of Russia in the summer of 1812 played into his hands, and in July of that year Castlereagh concluded a treaty of alliance with Russia which bound the two countries to help each other in their attempts to bring about the defeat of France.

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.
