Other estimates:
ca 143,000 dead and 81,000 injured of which 25,000 killed in action; 16,000 died of wounds; 89,000 died of disease[11][12]
The Crimean War, also known in Russia as the Eastern War (Russian: Восточная война, Vostochnaya Voina) (October 1853[13][14]–February 1856) was fought between the Russian Empire on one side and an alliance of France, the United Kingdom, the Kingdom of Sardinia (which would be absorbed into Italy in 1861), and the Ottoman Empire on the other. The war was part of a long-running contest between the major European powers for influence over territories of the declining Ottoman Empire. Most of the conflict took place on the Crimean Peninsula, with additional actions occurring in western Turkey and the Baltic Sea region.
The Crimean War is sometimes considered to be the first "modern" conflict and "introduced technical changes which affected the future course of warfare."[15]
The long chain of events leading to Britain's and France's declaring war on Russia on 28 March 1853 can be traced to the coup d'état of 1851 in France. Napoleon III had his ambassador to the Ottoman Empire force the Ottomans to recognise France as the "sovereign authority" in the Holy Land.[16]
Russia disputed this newest change in "authority" in the Holy Land. Pointing to two more treaties, one in 1757 and the other in 1774, the Ottomans reversed their earlier decision, renouncing the French treaty and insisting that Russia was the protector of the Orthodox Christians in the Ottoman Empire.
Napoleon III responded with a show of force, sending the ship of the line Charlemagne to the Black Sea, a violation of the London Straits Convention.[16] France's show of force, combined with aggressive diplomacy and money, induced Sultan Abdülmecid I to accept a new treaty, confirming France and the Roman Catholic Church as the supreme Christian authority in the Holy Land with control over the Christian holy places and possession of the keys to the Church of the Nativity, previously held by the Greek Orthodox Church.[17]
Tsar Nicholas I then deployed his 4th and 5th Army Corps along the River Danube, and had Count Karl Nesselrode, his foreign minister, undertake talks with the Ottomans. Nesselrode confided to Sir George Hamilton Seymour, the British ambassador in St. Petersburg:
[The dispute over the holy places] had assumed a new character - that the acts of injustice towards the Greek church which it had been desired to prevent had been perpetrated and consequently that now the object must be to find a remedy for these wrongs. The success of French negotiations at Constantinople was to be ascribed solely to intrigue and violence - violence which had been supposed to be the ultima ratio of kings, being, it had been seen, the means which the present ruler of France was in the habit of employing in the first instance.[18]
As conflict loomed over the question of the holy places, Nicholas I and Nesselrode began a diplomatic offensive which they hoped would prevent either Britain's or France's interfering in any conflict between Russia and the Ottomans, as well as to prevent their allying together.
Nicholas began courting Britain through Seymour. Nicholas insisted that he no longer wished to expand Imperial Russia, but that he had an obligation to Christian communities in the Ottoman Empire.
The Tsar next dispatched a diplomat, Prince Menshikov, on a special mission to the Porte. By previous treaties, the Sultan was committed "to protect the Christian religion and its churches." Menshikov attempted to negotiate a new treaty, under which Russia would be allowed to interfere whenever it deemed the Sultan's protection inadequate. Further, this new synod, a religious convention, would allow Russia to control the Orthodox Church's hierarchy in the Ottoman Empire. Menshikov arrived at Constantinople on 16 February 1853 on the steam-powered warship Gromovnik. Menshikov broke protocol at the Porte when, at his first meeting with the Sultan, he condemned the Ottomans' concessions to the French. Menshikov also began demanding the replacement of highly-placed Ottoman civil servants.
The British embassy at Constantinople at the time was being run by Hugh Rose, chargé d'affaires for the British. Using his considerable resources within the Ottoman Empire, Rose gathered intelligence on Russian troop movements along the Danube frontier, and became concerned about the extent of Menshikov's mission to the Porte. Rose, using his authority as the British representative to the Ottomans, ordered a British squadron of warships to depart early for an eastern Mediterranean cruise and head for Constantinople. However, Rose's actions were not backed up by Whitley Dundas, the British admiral in command of the squadron, who resented the diplomat for believing he could interfere in the Admiralty's business. Within a week, Rose's actions were cancelled. Only the French sent a naval task force to support the Ottomans.
At the same time, however, the British government of Prime Minister Aberdeen sent Lord Stratford. Lord Stratford convinced the Sultan to reject the treaty, which compromised the independence of the Turks. Benjamin Disraeli blamed Aberdeen and Stratford's actions for making war inevitable, thus starting the process by which Aberdeen would be forced to resign for his role in starting the war. Shortly after he learned of the failure of Menshikov's diplomacy, the Tsar marched his armies into Moldavia and Wallachia (principalities along the Danube, under Ottoman suzerainty, in which Russia was acknowledged as a special guardian of the Orthodox Church), using the Sultan's failure to resolve the issue of the Holy Places as a pretext. Nicholas believed that the European powers, especially Austria, would not object strongly to the annexation of a few neighbouring Ottoman provinces, especially given Russian involvement in suppressing the Revolutions of 1848.
