mines, if I may use this name given by Fulton to self-acting mines underwater, were among the novelties attempted by the Russians in their defences about Cronstadt and Sevastopol", as one American officer put it in 1860. For the campaign of 1856, Britain and France planned an attack on the main base of the Russian Navy in the Baltic sea – Kronstadt. The attack was to be carried out using armoured floating batteries. The use of the latter proved to be highly effective in attacking the sea fortress of Kinburn on the Black sea in 1855. Undoubtedly, this threat contributed on the part of Russia the decision on the conclusion of peace on unfavourable terms. White Sea theatre In late 1854, a squadron of three British warships led by HMS Miranda left the Baltic for the White Sea, where they shelled Kola (which was destroyed) and the Solovki. Pacific theatre Minor naval skirmishes also occurred in the Far East, where at Petropavlovsk on the Kamchatka Peninsula a British and French Allied squadron including under Rear Admiral David Price and a French force under Counter-Admiral Auguste Febvrier Despointes besieged a smaller Russian force under Rear Admiral Yevfimiy Putyatin. In September 1854, an Allied landing force was beaten back with heavy casualties, and the Allies withdrew. The victory at Petropavlovsk was for Russia in the words of the future military Minister Milyutin "a ray of light among the dark clouds". The Russians escaped under the cover of snow in early 1855 after Allied reinforcements arrived in the region. The Anglo-French forces in the Far East also made several small landings on Sakhalin and Urup, one of the Kuril Islands. Piedmontese involvement Camillo di Cavour, under orders of Victor Emmanuel II of Piedmont-Sardinia, sent an expeditionary corps of 15,000 soldiers, commanded by General Alfonso La Marmora, to side with French and British forces during the war. This was an attempt at gaining the favour of the French, especially when the issue of uniting Italy would become an important matter. The deployment of Italian troops to Crimea, and the gallantry shown by them in the Battle of the Chernaya (16 August 1855) and in the siege of Sevastopol, allowed the Kingdom of Sardinia to be among the participants at the peace conference at the end of the war, where it could address the issue of the Risorgimento to other European powers.
