Field Marshal FitzRoy James Henry Somerset, 1st Baron Raglan, {'1': ", '2': ", '3': ", '4': "} (30 September 1788 – 28 June 1855), known before 1852 as Lord FitzRoy Somerset, was a British Army officer.
 As a junior officer he served in the Peninsular War and the Hundred Days, latterly as military secretary to the Duke of Wellington.
 He also took part in politics as Tory Member of Parliament for Truro before becoming Master-General of the Ordnance.
 He became commander of the British troops sent to the Crimea in 1854: while his primary objective was to defend Constantinople he was ordered to besiege the Russian Port of Sevastopol.
 After an early success at the Battle of Alma, a failure to deliver orders with sufficient clarity caused the fateful Charge of the Light Brigade at the Battle of Balaclava.
 Despite further success at the Battle of Inkerman, a piecemeal allied assault on Sevastopol in June 1855 was a complete failure.
 Raglan died later that month from a mixture of dysentery and clinical depression.
Generaloberst, in English Colonel General, was, in Germany and Austria-Hungary—the German "Reichswehr" and "Wehrmacht", the Austro-Hungarian Common Army, and the East German National People's Army, as well as the respective police services—the second highest general officer rank, ranking above full general but below general field marshal.
 It was equivalent to "Generaladmiral" in the "Kriegsmarine" until 1945, or to Flottenadmiral in the "Volksmarine" until 1990.
 The rank was the highest ordinary military rank and the highest military rank awarded in peacetime; the higher rank of general field marshal was only awarded in wartime by the head of state.
 In general, a Generaloberst had the same privileges as a general field marshal.
Generalfeldmarschall (English: general field marshal, field marshal general, or field marshal ;    ; abbreviated to Feldmarschall) was a rank in the armies of several German states and the Holy Roman Empire; in the Habsburg Monarchy, the Austrian Empire and Austria-Hungary, the rank "Feldmarschall" was used.
 The rank was the equivalent to "Großadmiral" (English: Grand admiral ) in the "Kaiserliche Marine" and "Kriegsmarine", a five-star rank, comparable to OF-10 in today's NATO naval forces.
Field Marshal Sir Richard James Dacres, GCB (1799 – 6 December 1886) was a British Army officer during the nineteenth century.
 Born into a substantial naval dynasty, he would achieve similar status in the military, commanding three troops of Royal Horse Artillery at the Battles of Alma in September 1854, Balaclava in October 1854 and Inkerman in November 1854, and throughout the Siege of Sevastopol during the Crimean War and eventually rising to the rank of field marshal.
Günther von Kluge (30 October 1882 – 19 August 1944) was a German field marshal during World War II.
 Kluge held commands on both the Eastern and Western Fronts.
 Although Kluge was not an active conspirator in the 20 July plot, he committed suicide on 19 August 1944, after having been recalled to Berlin for a meeting with Hitler in the aftermath of the failed coup.
 He was replaced by Field Marshal Walter Model.
Fritz Erich Georg Eduard von Lewinski, known as Erich von Manstein (24 November 1887 – 9 June 1973), was a German commander of the "Wehrmacht", Nazi Germany's armed forces during the Second World War.
 He attained the rank of field marshal.
Field marshal (or field marshal, abbreviated as FM) ( , ) is a five–star general officer rank and the highest attainable rank in the Indian Army.
 Field marshal is ranked immediately above general, but not exercised in the regular army structure.
 It is a largely ceremonial or wartime rank, having been awarded only twice.
 A field marshal's insignia consists of the national emblem over a crossed baton and sabre in a lotus blossom wreath.
Field Marshal Kodandera "Kipper" Madappa Cariappa, OBE (28 January 1899 – 15 May 1993) was the first Indian commander-in-chief (C-in-C) of the Indian Army.
 He led Indian forces on the Western Front during the Indo-Pakistani War of 1947.
 He is one of only two Indian Army officers to hold the five-star rank of field marshal; the other being Field Marshal Sam Manekshaw.
 He was appointed commander-in-chief of the Indian Army in 1949.
The Siege of Sevastopol also known as the Defence of Sevastopol (Russian: Оборона Севастополя , transliteration: "Oborona Sevastopolya") or simply the Battle of Sevastopol (German: Schlacht um Sewastopol) was a military battle and a siege that took place on the Eastern Front of the Second World War.
 The campaign was fought by the Axis powers of Germany, Romania, and Italy against the Soviet Union for control of Sevastopol, a port in the Crimea on the Black Sea.
 On 22 June 1941 the Axis invaded the Soviet Union during Operation Barbarossa.
 Axis land forces reached the Crimea in the autumn of 1941 and overran most of the area.
 The only objective not in Axis hands was Sevastopol.
 Several attempts were made to secure the city in October and November 1941.
 A major attack was planned for late November, but heavy rains delayed the Axis attack until 17 December 1941.
 Under the command of Erich von Manstein, Axis forces were unable to capture Sevastopol during this first operation.
 Soviet forces launched an amphibious landing on the Crimean peninsula at Kerch in December 1941 to relieve the siege and force the Axis to divert forces to defend their gains.
 The operation saved Sevastopol for the time being, but the bridgehead in the eastern Crimea was eliminated in May 1942.
Lieutenant field marshal, also frequently historically field marshal lieutenant (German: "Feldmarschall-Leutnant" , formerly "Feldmarschallleutnant", historically also "Feldmarschall-Lieutenant" and, in official Imperial and Royal Austrian army documents from 1867 always "Feldmarschalleutnant", abbreviated "FML"), was a senior army rank in certain European armies of the 17th to 20th centuries.
 It emerged as the rank of field marshal (German: "Feldmarschall" ) came to be used for the highest army commander in the 17th century (having originally been the equivalent of a cavalry colonel).
 In German-speaking countries the commander-in-chief usually appointed an "under marshal" ("Untermarschall") or "lieutenant field marshal" to support and represent the field marshal.
 Amongst his functions as the personal deputy to the field marshal, were the supervision of supply depots and routes, and inspection of the guards.
