Palmerston took a hard line on the war; he wanted to expand the fighting, especially in the Baltic where St. Petersburg could be threatened by superior British naval power. His goal was to permanently reduce the Russian threat to Europe. Sweden and Prussia were willing to join, and Russia stood alone. However, France, which had sent far more soldiers to the war than Britain, and had suffered far more casualties, wanted the war to end, as did Austria. In March 1855 the old Tsar died and was succeeded by his son, Alexander II, who wished to make peace. However, Palmerston found the peace terms too soft on Russia and so persuaded Napoleon III of France to break off the peace negotiations until Sevastopol could be captured, putting the allies in a stronger negotiating position. In September Sevastopol finally surrendered and the allies had full control of the Black Sea theatre. Russia came to terms. On 27 February 1856 an armistice was signed and after a month's negotiations an agreement was signed at the Congress of Paris. Palmerston's demand for a demilitarised Black Sea was secured, although his wish for the Crimea to be returned to the Ottomans was not. The peace treaty was signed on 30 March 1856. In April 1856 Palmerston was appointed to the Order of the Garter by Victoria.
