Karel Janoušek, (30 October 1893 – 27 October 1971) was a senior Czechoslovak Air Force officer. He began his career as a soldier, serving in the Austrian Imperial-Royal Landwehr (1915–16), Czechoslovak Legion (1916–20) and Czechoslovak Army (1920–24).

In 1924 Janoušek transferred to the Czechoslovak Air Force and in 1926 he qualified as an aircraft pilot. In 1930 he co-wrote a textbook on aerial warfare tactics. In the 1930s he was a staff officer. From 1936 he studied meteorology and geophysics at the Charles University and in 1939 he was awarded a doctorate in natural sciences (RNDr).

In the Second World War Janoušek escaped first to France and then the United Kingdom. In the UK he commanded the RAF's Czechoslovak squadrons, was knighted by HM King George VI and ultimately promoted to Air Marshal. In occupied Czechoslovakia the Nazis retaliated against Janoušek's Free Czechoslovak service by jailing his wife and much of their family.

In 1945 Janoušek returned to Czechoslovakia, where he found his wife and several of their relatives had died in imprisonment. He was sidelined by the increasingly pro-Communist commanders of the Czechoslovak Air Force. After the 1948 Czechoslovak coup d'état Janoušek was court-martialled, sentenced to 18 years in prison and stripped of his rank, doctorate and awards. In 1949 his sentence was extended to 19 years. In 1950 it was extended to life imprisonment for a separate offence, but in 1955 this sentence was shortened to 25 years.

In 1956 Janoušek' sentences were reduced and in 1960 he was released in a Presidential amnesty. A military tribunal cancelled his convictions in the Prague Spring in 1968. Janoušek died in Prague in 1971. He was not fully rehabilitated until after the 1989 Velvet Revolution ended the Communist dictatorship.

Early life Janoušek was born in Přerov, Moravia, the second child of a clerk on the Imperial Royal Austrian State Railways. His father, also called Karel Janoušek, was a founding member of the Czech Social Democratic Party. Janoušek's mother, Adelheid, died when Janoušek was two years old. His father remarried and had another nine children by his second wife, Božena.

Janoušek completed secondary school in 1912 and then went to a German business school. He spent the first three years of his working life as a clerk in a local business that belonged to a distant relative.

In June 1915 Janoušek was conscripted into the Austrian Imperial-Royal Landwehr, trained at Opava in Czech Silesia and was promoted to corporal. He served in the 57th Infantry Regiment and fought in the Sixth Battle of the Isonzo on the Italian Front.

Janoušek was then transferred to the Eastern Front to resist the Russian Brusilov Offensive. Russian forces captured him on 2 July 1916 and detained him in a prisoner-of-war camp near Kiev, Ukraine. However, on 1 August 1916 Janoušek was released to join the II Volunteer Division of the Serbian Army in Odessa, which recognised his Austrian rank of corporal.

Czechoslovak Legion 1916–20

On 14 October 1916 Janoušek transferred to the Czechoslovak Legion as a private and joined its 1st Rifle Regiment at Boryspil. In 1917 after the February Revolution the Czechoslovak Legion became part of the Russian 7th Army. Janoušek fought at the Battle of Zborov on 1–2 July 1917. He was wounded on 18 July, in hospital until August and then promoted to warrant officer.

After the October Revolution the Czechoslovak Legion suffered internal strife between pro- and anti-Bolshevik factions. Janoušek was in the anti-Bolshevik faction, which ultimately won. The Legion disobeyed Edvard Beneš' order to surrender "rebels" to the Bolsheviks, and in October 1918 Janoušek was promoted to interim commander of the 7th Company of the II Battalion of the 1st Regiment.

The Legion joined one of the White Armies in the Russian Civil War. Janoušek fought in battles against the Red Army at Bugulma, Melekess, Braudina, Simbirsk and Kazan. On 7 August 1918 he took command of the 3rd Company of the 1st Regiment. In September the Red Army forced the Legion to retreat from Kazan. In October Czechoslovakia declared independence from Austria-Hungary, and in November the First World War ended with the armistices of Villa Giusti and Compiègne. But the Czechoslovak Legion was trapped in Russia, with the Red Army blocking its escape to the west.

The Legion therefore fought its way east across Siberia to Vladivostok to be evacuated by sea. At Tayshet in May 1919 it defended the Trans-Siberian Railway from a Red Army attack. Janoušek was wounded again and treated in hospital in Irkutsk until the end of June. On 25 May France, one of the interventionist powers, awarded him the Croix de Guerre with palm leaf. Janoušek's company set off for Vladivostok on 10 October 1919. On 6 December the unit sailed from Vladivostok aboard a Japanese steamship, the Yonan Maru. Janoušek and his unit finally reached Prague on 2 February 1920.

Czechoslovakia 1920–39 Czechoslovak Army 1920–24 The Czechoslovak Legion formed the basis of the new Czechoslovak Army. In May 1920 Janoušek took command of the 2nd Infantry Regiment at Dobšiná in Slovakia and on 1 July he was made Second in Command of the XXII Brigade at Košice. On 21 February 1921 he was promoted to staff captain and given command of the 12th Artillery Regiment at Uzhhorod in Carpathian Ruthenia, but in October he was transferred to a desk job in Košice.

In September 1923 Janoušek graduated from War College. He was briefly stationed at the Provincial Headquarters in Prague, but then in February 1924 started training at Cheb in Bohemia to become a pilot.

Czechoslovak Air Force 1924–39 In January 1925 Janoušek was appointed Commander of the Xth Air Reconnaissance Course. On 19 November 1925 he married Anna Steinbachová, née Hoffmannová. On 1 January 1926 he qualified as a pilot. He was not an outstanding pilot, but he was good at reconnaissance, air navigation and meteorology. On 2 December 1926 he was promoted to major of the General Staff. In September 1927 he went on a one-month attachment to the French Armée de l'Air. On 28 February 1928 he was promoted to lieutenant colonel. By now he was Second in Command of the Military Flying School. He co-authored a book on aerial warfare tactics, inspired by the ideas of the Italian military theorist Giulio Douhet, which was published in May 1930.

Janoušek was then posted to Slovakia and, on 31 December 1930, promoted to command the 6th Flying Regiment. In 1930–32 his duties also included training officers to be higher commanders. On 31 July 1933 he was promoted to full colonel. By 1936 he was a brigadier general and a Provincial Commander of the Air Force. Bad weather was a major limitation on aviation, and caused about half of all air accidents. Therefore, in 1936 Janoušek started studying meteorology and geophysics at the Charles University in Prague.

During the Sudeten Crisis Czechoslovakia ordered a partial mobilization on 21 May and complete mobilization on 23 September. Janoušek commanded the Air Force of General Sergei Wojciechowski's 1st Army, which was to protect the frontier with Nazi Germany from České Budějovice in the southwest to Králíky in the north. But on 29 September France and the United Kingdom signed the Munich Agreement with Germany, forcing Czechoslovakia to cede the Sudetenland without a fight.

On 15 March 1939 Germany occupied Czechoslovakia and created the Protectorate of Bohemia and Moravia, which was required to dissolve its army and air force. Nevertheless, Janoušek completed his course at Charles University and graduated with a doctorate in natural sciences (RNDr) on 23 June.

Hundreds of Czechoslovak army and air force personnel responded to the German occupation by escaping to Poland or France. The secret Obrana národa Czechoslovak resistance organisation helped Janoušek to cross into Slovakia on 15 November 1939. From there he travelled via Hungary, Yugoslavia, Greece and Beirut in French-ruled Lebanon to reach France.

Second World War

France 1939–40 Janoušek reported for duty in Paris on 1 December 1939. He was assigned to the Czechoslovak Military Administration (CsVS) as Head of the 3rd (Air) Department, de facto commanding the free Czechoslovak Air Force being formed in France, for which there were agreements between the French and Free Czechoslovak governments. But turning the force into a reality was hampered by inaction of the French Ministry of Aviation, lack of equipment, and Czechoslovak air force personnel being scattered at more than 20 locations in France and the French Empire. On 15 March 1940 Janoušek was replaced by his senior and rival, Brig Gen Alois Vicherek.

Janoušek was then to command a Czechoslovak Air Force training centre, which was to be built at Cognac in western France. It never materialised. On 10 May Germany invaded the Netherlands, Belgium and France. As French armed forces were collapsing, on 18 June Janoušek and a large group of Czechoslovak airmen left Bordeaux aboard a small Dutch ship, the Karanan, which reached Falmouth in England on 21 June. The next day France capitulated to Germany.

United Kingdom 1940–45 On 21 June, the day before France capitulated, the former Czechoslovak ambassador to the UK Jan Masaryk was reported as stating that Czechoslovakia "now has 1,500 young, trained pilots in England ready for service with the Allied air forces". However, Brig Gen Vicherek was stuck in France until 27 June and did not reach Britain until 7 July. Hence for a fortnight Janoušek was the most senior Czechoslovak Air force officer in the United Kingdom.

There was not yet a military agreement between the Czechoslovak government-in-exile and the UK, but Janoušek secured the help of the UK's former air attaché to Prague, Wg Cdr Frank Beaumont. It was agreed that all Czechoslovak airmen could enlist in the RAF Volunteer Reserve and that air force units of Czechoslovak personnel would be formed under RAF command. An Inspectorate of Czechoslovak Air Force was formed on 12 July 1940. The UK War Department gave Janoušek the rank of Air Commodore, effectively giving him oversight of all Czechoslovak units of the RAF.

However, the Defence Ministry of the Czechoslovak government-in-exile did not confirm Janoušek's appointment until 15 October 1940, followed by a Presidential Decree to the same effect on 18 June 1941. Both President Beneš and his Defence Minister, Brig Gen Sergej Ingr, criticised Janoušek for securing an agreement that excluded the government-in-exile from any control over Czechoslovak units and personnel in the RAF. It also excluded Brig Gen Vicherek from the chain of command. But it also ensured that the RAF enlisted, trained and equipped 88 Czechoslovak fighter pilots in time for them to fight in the Battle of Britain, including No. 310 Squadron RAF which was the RAF's first squadron formed almost entirely of Czechoslovak personnel.

As Inspector of the Czechoslovak Air Force, Janoušek too was outside the RAF's immediate chain of command. His job was to inspect the RAF's Czechoslovak squadrons, organise training, propose which Czechoslovak officers should be promoted to command those squadrons, and have meetings with the President Beneš and Defence Minister Ingr. In the course of the war the Air Force Inspectorate expanded to include other functions including medical, transport and pastoral services. For a time Janoušek's chief of staff was Wg Cdr Josef Schejbal, who in 1941 commanded No. 311 Squadron RAF, the RAF's only Czechoslovak heavy bomber squadron.

By May 1941 the RAF had up to 1,600 Czechoslovak personnel. Nos. 310, 311, 312 and 313 Squadrons were almost entirely Czechoslovak, as was one flight of 68 Squadron. There were also numerous Czechoslovak personnel serving in other RAF units.
