Was there a man dismay'd?
Not tho' the soldier knew
Someone had blunder'd:
Theirs not to make reply,
Theirs not to reason why,
Theirs but to do and die:
Into the valley of Death
Rode the six hundred."
The Crimean War was a war fought from 1853 to 1856 between the Russian Empire on one side and an alliance consisting of the British Empire, the French Empire (no not that empire — his nephew's), the Kingdom of Sardinia, and the Ottoman Empire (today's Turkey). It also counts as the 13th of Russia's 16 wars with Turkey (the first stemming back to the mid 16th Century)
Sometimes known in Britain as the Russian War.
This all started when French Emperor Napoleon III induced the Ottoman Sultan Abdulmecid I to recognize France as the protector of the Christian peoples in Ottoman Palestine (which at the time meant the whole eastern shore of the Mediterranean: not just modern Israel/Palestine, but also Lebanon and bits of Syria and Turkey). This, of course, did not sit well with the Russian Tsar, Nicholas I (not the other Nick), as it had the practical effect of favoring the Catholic communities of the region (particularly the Maronites of Lebanon) over the various Eastern Orthodox communities of which Russia regarded itself as the natural protector. As a result, Russia sent troops to the Ottoman-controlled Danubian Provinces (in today's Romania), forcing Abdulmecid to declare war on Russia. A surprise attack on Turkish ships in the Battle of Sinop drew Britain and France into the war. The Kingdom of Piedmont came in for reasons unclear to everyone but its Prime Minister, Count Cavour.
The war was fought on three fronts. The major front was the Danubian Front, fought in the Balkans (mainly Romania); the Black Sea and the Crimean Peninsula are the other two. The name of the war comes from the fact most of the fighting was in the Crimea, particularly in the port city of Sevastopol, which was besieged by the Allies for almost a year before the Russians surrendered.
Other fronts were the Caucasus Campaign (fought mainly in Armenia and Northwestern Turkey), with its major battle being a 5-month siege in Kars, and the Naval Campaign (fought in the Baltic and White Seas as well as the Pacific Ocean) which saw no major fleet action, because outnumbered and outclassed Russian fleet mostly stayed in protected bases (France and Britain already turned a significant parts of their previously-sail fleets to steam propulsion, while Russia only started to)
A major cultural touchstone is the Charge of the Light Brigade during the Battle of Balaclava (25 October 1854). Over six hundred English cavalry, following ambiguous instructions misdelivered, courageously charged a heavily-defended Russian outpost and suffered massive casualties. Tennyson wrote a poem about it. On the other side of frontlines, we have the long and heroic defense of Sevastopol, which became a major point of pride for both Russian military and culture (Tolstoy wrote his "Sevastopol Sketches" about it), and sucsessful defense of Petropavlovsk-Kamchatsky, where small Russian garrison and volunteers sucsessfully routed much stronger Franco-British landing force.
In the end it was an allied victory. The resulting Treaty of Paris (the first since The Napoleonic Wars) gave the Danubian Principality of Moldavia the Budjak, both Moldavia and Wallachia autonomy (to be monitored by the victorious powers; this set off the final chain of events culminating in the official formation of Romania a few years later) and demilitarized the Black Sea (and, unimportantly, the Russian-controlled Åland Islands in Finland).
Russia's setback also instituted greater reforms in the military, which would be put to good use when they fought Turkey again 20 years later. The British military also underwent drastic reforms after their poor performance in this conflict (the aforementioned Light Brigade fiasco in particular having drawn enormous criticism, even if the actual charge was seen as heroic at the time), especially in medicine, sanitation and officer selection.
Recent historians (Trevor Royle, Orlando Figes) argue that the Crimean War had farther-reaching impact than is generally thought, even beyond medical and military reforms. The unification of Italy was an indirect result of the Piedmontese Kingdom's participation in the war (see below). The blocking of Russian expansion into Eastern Europe, and waning of Austrian power, left a power vacuum which was ultimately filled by a soon-to-be-unified Germany. Turkish nationalism was also stirred by their role in the conflict. All of these had drastic consequences a few decades later. It was also the first time in the "modern" era that France and Britain cooperated heavily in a military conflict, which was particularly notable as a few decades prior, the two had been at each other's throats as primary belligerents in the greatest war the world had yet known, and even before that had been bitter enemies for centuries. The earliest seeds of what would eventually become the Allies of the World Wars and later NATO were probably planted in this conflict.
The Crimean War in fiction:
- The "Sevastopol Sketches", by Leo Tolstoy, who actually fought in the siege. Tolstoy is more famous for much longer works like War and Peace.
- Flashman at the Charge by George MacDonald Fraser.
- The Charge of the Light Brigade, 1936 film starring Errol Flynn and very Very Loosely Based on a True Story.
- Max Hennessey's trilogy about three generations of the Goth family, founders of the (fictional) 19th Lancers, starts with a Goth as an Ensign Newbie at the Charge of the Light Brigade. It's by no means the last disastrous cavalry charge a Goth will take part in.
- A more accurate remake of The Charge of the Light Brigade was released in 1968.
- The Thursday Next series is set in an Alternate History where the Crimean War continued into the 21st century.
- In Anti-Ice by Stephen Baxter, the discovery of the titular Phlebotinum results in a sudden and explosive end to the Crimean War.
- "The Trooper", one of Iron Maiden's most famous songs, retells the Charge of the Light Brigade from the point of view of one of the British cavalrymen involved.
- Mentioned in an unusual context in this hilarious post on the discussion board of AlternateHistory.com. The post spoofs the overuse of WWII as a setting for FPS games by inverting it to the Crimean War as the most popular game setting and WWII getting barely any mention at all in games.
- "Oolannin sota" (Åland's War) is a Finnish march that tells about the Battle of Bomarsund.
- The Great Train Robbery (1979) directed by Michael Crichton based on his novel starring Sean Connery and Donald Sutherland. It was based on a real robbery in 1855 Britain of £12,000 worth of gold being shipped by train to finance the Crimean War.
- Gets a nod in the Star Trek: Deep Space Nine episode "Sacrifice of Angels", when a Starfleet force of 600 ships prepares to attack a Dominion fleet twice their number. Chief O'Brien and Julian Bashir begin quoting Alfred, Lord Tennyson's poem at each other. When an alien crewmember asks for an explanation of the poem, they assure him he'd rather not hear it, given the part Starfleet was about to play.
- Assassin's Creed: Syndicate is set in Victorian London in 1868 and has many references to the Crimean War. It features Lord Cardigan as one of the Assassination targets. Lord Cardigan describes himself many times as "the Hero of Balaclava". Shaun Hastings who writes the in-game Enclyopedia offers a hilarious, and cruelly accurate, summary of the conflict:
Shaun Hastings: It was also one of the first truly "modern" wars, if large masses of men shooting each other over which toff got to call themselves Emperor of Wherever can be called "modern." Technology like the exploding artillery shell, the railroad, and the telegraph shaped the conflict, and the advent of photographic technology meant it was one of the first wars to be documented in the press. This was particularly delightful in that the great legacy of the Crimean war was the rank incompetence and general mismanagement on the part of the leadership of all sides. Something to really be proud of there. If you're going to be inept, be REALLY inept. For the citizens on the home front puffed up with patriotic fervour, this was a bit like going to see your favourite band in concert only to realise that they only sounded good thanks to auto-tune and ruthless editing.
- A Bride's Story depicts traditional life in Central Asia around this time. The protagonists Amir and Karluk live east of the Aral sea where the increasing expansion and meddling of Russia is being felt. Mr. Henry Smith, an English ethnographer visiting their village, undertakes a journey to Ankara, Turkey so that he can return with a camera and document a way of life which may soon die out. At least once along the way he gets detained as a suspected spy. When he arrives in Ankara his friend Mr. Hawking is writing about skirmishing between the Russians and the Ottomans. and although war hasn't officially been declared yet everyone can see that it's going to happen. Hawking tries to discourage his friend from going back during such a dangerous time, only to relent in the face of Henry's determination to risk his life for his work.
- Doctor Who: In "War of the Sontarans", the Doctor and her companions find themselves in mid-1800s Sevastopol, in the midst of The Crimean War. However, this war is not being fought against the Russians; instead, the British army is marching against the Sontarans, who apparently have been on Earth as long as anyone can remember.
