The Anglo-Russian occupation of Naples was the stationing of British and Russian forces in the Kingdom of Naples from the summer of 1805 until January 1806 during the War of the Third Coalition. Background A previous cooperation in July 1799 between British admiral Horatio Nelson and Russian admiral Ushakov led to the reconquest of Naples and suppression of the pro-French revolutionary Parthenopaean Republic. The war ended with the Treaty of Florence (28 March 1801), in which Naples had to make various concessions to France, including closing its ports to all Ottoman and British ships, giving France preferential treatment in trade, and allowing French garrisons in the Apulian trading ports of Pescara, Brindisi and Otranto and the province of Terra d'Otranto on Neapolitan costs. For his upcoming confrontation with Austria and Russia in Central Europe in autumn 1805, French Emperor Napoleon sought to secure his southern flank. He was willing to abandon the French-occupied coastal cities in Apulia to Naples in exchange for Neapolitan neutrality in the war ahead. King Ferdinand of Naples and Sicily agreed and signed a treaty with Napoleon. Course However, after receiving the Apulian cities, Ferdinand soon went back on his promise and allied himself with France's enemies Britain and Russia, which landed troops in Naples with his permission in order to guard against a possible French invasion, and to plan an attack on the Napoleonic states in central and northern Italy. The British commander was general James Henry Craig, who had ill health at the time and had 7,000 troops, while the Russian forces were led by Maurice Lacy and Roman Anrep. The combined army was too weak and poorly equipped to withstand any serious French attack. When the combined Austro–Russian Army was dealt a severe blow by Napoleon at the Battle of Austerlitz on 2 December 1805, 30,000 French troops were freed up for a campaign against Naples. Tsar Alexander I of Russia ordered his troops to withdraw from southern Italy to Corfu, which they did after Lacy received the tsar's dispatch on 7 January 1806. Meanwhile, Craig was awaiting orders from Lord Castlereagh; he wrote on 30 December that he received his most recent instructions on 16 October. Against the wishes of ambassador Hugh Elliot, who warned evacuation would provoke the French to attack, Craig had the vastly outnumbered British troops depart Naples and set sail for the island of Sicily on 10 January
