Unlike Nesselrode, a firm supporter of the Holy Alliance and its legitimist principles, Gorchakov took a pragmatic view of Russia’s role on the Continent. In his opinion, Russia should not form alliances that committed it to general principles, such as the defence of legitimate monarchies, as it had done before the Crimean War. The war had shown that Russia could not rely in any way on the solidarity of legitimate European monarchies. Nesselrode’s policy had made Russia vulnerable to the failings of other governments, Austria in particular, a power Gorchakov despised from his time as ambassador in Vienna. Instead, Gorchakov believed Russia should focus its diplomacy on its own national interests, and ally with other powers regardless of their ideology to further those interests. Here was a new type of diplomacy, the realpolitik later practised by Bismarck.
The Russians tested the Paris Treaty from the start, focusing on minor issues which they could exploit to open up divisions in the Crimean alliance. In May 1856 they claimed ownership of a lighthouse on tiny Serpent Island, in Turkish waters near the mouth of the Danube delta, and landed seven men with an officer to take up residence in the lighthouse. Walewski was inclined to let the Russians have the insignificant island, but Palmerston was adamant that they had to be ejected, on the grounds that they were infringing Turkish sovereignty. When the captain of a British ship made contact with the Turks on Serpent Island, he was told that they did not mind the Russians being there: they saw them as guests and were happy to sell them their supplies. Palmerston put his foot down. ‘We must avoid the fatal mistake made by Aberdeen in permitting the early movements and indications of Russian aggression to go on unnoticed and unrepressed,’ he wrote to Clarendon on 7 August. Orders were prepared to send the gunboats in to remove the Russians physically, but John Wodehouse, the British envoy in St Petersburg, was doubtful whether Britain had the right to do this, and the Queen shared these doubts, so Palmerston backed down and diplomatic pressure was used instead. Gorchakov insisted that the island had been owned by the Russians since 1833, and appealed to the French, who were thus manoeuvred into a position of international mediation between Britain and Russia.28
Meanwhile, the Russians launched a second challenge to the Paris Treaty in connection with the border between Russian Bessarabia and Turkish-controlled Moldavia. By an accident of mapping and confusion over names, the allies had drawn the border running to the south of an old village called Bolgrad, 3 kilometres to the north of New Bolgrad, a market town situated on the shores of Lake Yalpuk, which runs into the Danube. The Russians made use of the lack of clarity, claiming that they should be given both Bolgrads, and thus joint ownership of Lake Yalpuk. Palmerston insisted that the border should remain at the old village – the intention of the treaty having been to deprive the Russians of access to the Danube. He urged the French to remain firm and show a united front against the Russians, who would otherwise exploit their differences. But the French were happy to concede the Russian claim as a matter of good faith, though they then proposed that the boundary should run along a narrow strip of land between the market town and Lake Yalpuk, thereby granting more territory to the Russians but depriving them of access to the lake. Once again, the French acted as intermediaries between Russia and Britain.
