Map of Crimea from the Sea of Azov, probably from the period of Russia's war with Turkey. In September 1854, 60,000 troops of the British, French and Turkish armies landed on the Crimean Peninsula. They were later joined (in April 1855) by Sardinian troops as well. - The allies occupied the peninsula without much fighting, except for the city and fortress of Sevastopol (where the headquarters of the Russian Black Sea Fleet was located), whose siege, combined with heavy bombardment, lasted for 11 months, until September 1855 [in part, after wikipedia.co.uk].
