Question: what mutiny in India was thwarted by MI5(b) during World War I?

full_context: Document 1: The Indian War of Independence (book): The Indian War of Independence is an Indian nationalist history of the 1857 revolt by Vinayak Damodar Savarkar that was first published in 1909. The book, initially written in Marathi, was penned by Savarkar in response to celebrations in Britain of the 50th anniversary of the 1857 Indian uprising with records from India Office archives and the whole project received support from Indian nationalists in Britain including the likes of Madame Cama, V.V.S. Iyer and M.P.T. Acharya, as well as Indian students who had dared not show their support or sympathy for India House openly. Published during Savarkar's stay in London at the India House, the book was influenced by histories of the French Revolution and the American Revolution, as much as it sought to bring the Indian movement to public attention in Britain as well as to inspire nationalist revolution in India.
Document 2: Revolutionary movement for Indian independence: The "Revolutionary movement for Indian independence"' is a part of the Indian independence movement comprising the actions of the underground revolutionary factions. Groups believing in armed revolution against the ruling British fall into this category, as opposed to the generally peaceful civil disobedience movement spearheaded by Mohandas Karamchand Gandhi. The revolutionary groups were mainly concentrated in Bengal, Maharashtra, Bihar, the United Provinces and Punjab. More groups were scattered across India.
Document 3: MI5(g): The MI5(g), or the MI5 G section, was a branch of MI5 that was formed during World War I to address the wartime espionage operation by the Indian revolutionary movement in Europe. The department arose by renaming the MO5(g), which was renamed MI5(g) in 1916. The MI5 itself, working under Vernon Kell, had a number of India experts at the beginning of the war. In September 1916, a special section, the MI5(d), section was formed to operate counter-espionage networks throughout the British Empire. Another subsection, the MI5(b), was formed in January 1917 to deal specifically with Indians and "other oriental races". The MI5(g) had 27 officers in its staff, eight of whom had served in India before the war. Among them were ex-Indian civil servants including Robert Nathan and H. L. Stephenson. The main emphasis of this counter-espionage network was to prevent the subversion of Indian troops in the European theatre. The organisation, especially under Nathan, worked closely with the Special Branch of the Scotland Yard in Britain and with the Indian Political Intelligence Office headed by John Wallinger, which operated a network of spies in neutral Switzerland which a number of the Indian revolutionaries and members of the Berlin Committee used as a base.
Document 4: Indian Legion: The Indian Legion (German: "Indische Legion" ), officially the Free India Legion (German: "Legion Freies Indien" ) or Infantry Regiment 950 (Indian) (German: "Infanterie-Regiment 950 (indisches), I.R. 950" ) and later the Indian Volunteer Legion of the Waffen-SS (German: "Indische Freiwilligen Legion der Waffen-SS" ), was a military unit raised during the Second World War in Nazi Germany. Intended to serve as a liberation force for British-ruled India, it was made up of Indian prisoners of war and expatriates in Europe. Because of its origins in the Indian independence movement, it was known also as the "Tiger Legion", and the "Azad Hind Fauj". Initially raised as part of the German Army, it was part of the "Waffen-SS" from August 1944. Indian independence leader Subhas Chandra Bose initiated the legion's formation, as part of his efforts to win India's independence by waging war against Britain, when he came to Berlin in 1941 seeking German aid. The initial recruits in 1941 were volunteers from the Indian students resident in Germany at the time, and a handful of the Indian prisoners of war who had been captured during the North Africa Campaign. It would later draw a larger number of Indian prisoners of war as volunteers.
Document 5: Research and Analysis Wing: The Research and Analysis Wing (R&AW or RAW) is the primary foreign intelligence agency of India. It was established in 1968 following the intelligence failures of the Sino-Indian and Indo-Pakistani wars, which persuaded the Government of India to create a specialised, independent agency dedicated to foreign intelligence gathering; previously, both domestic and foreign intelligence had been the purview of the Intelligence Bureau.
Document 6: Department of Criminal Intelligence: The Department of Criminal Intelligence was the central domestic and foreign intelligence organisation in India under the British Raj. It was set up in April 1904 under Sir Harold Stuart on recommendations of H.L. Fraser, following the report of the 1903 Police Commission instituted by the then Viceroy of India Lord Curzon. It remained the most important intelligence organisation in India until the end of the Raj in 1947.
Document 7: 1915 Singapore Mutiny: The 1915 Singapore Mutiny, also known as the 1915 Sepoy Mutiny or the Mutiny of the 5th Light Infantry, was a mutiny involving up to half of a regiment of 850 sepoys (Indian soldiers) against the British in Singapore during the First World War, linked with the 1915 Ghadar Conspiracy. The mutiny, on 15 February 1915, lasted nearly seven days. It resulted in the deaths of eight British officers and soldiers, two Malay officers and one soldier, 14 British civilians, five Chinese and Malay civilians and one German internee before it was finally quelled by British forces and Allied naval detachments.
Document 8: Ghadar Mutiny: The Ghadar Mutiny (Hindustani: ग़दर राज्य-क्रान्ति, غدر ریاست - کرانتی "Ġadara Rājya-krānti"), also known as the Ghadar Conspiracy, was a plan to initiate a pan-Indian mutiny in the British Indian Army in February 1915 to end the British Raj in India. The plot originated at the onset of the First World War, between the Ghadar Party in the United States, the Berlin Committee in Germany, the Indian revolutionary underground in British India and the German Foreign Office through the consulate in San Francisco. The incident derives its name from the North American Ghadar Party, whose members of the Punjabi Sikh community in Canada and United States were one of the most prominent participants in the plan. It was the most prominent amongst a number of plans of the much larger Hindu–German Mutiny, formulated between 1914 and 1917 to initiate a Pan-Indian rebellion against the British Raj during World War I. The mutiny was planned to start in the key state of Punjab, followed by mutinies in Bengal and rest of India. Indian units as far as Singapore were planned to participate in the rebellion. The plans were thwarted through a coordinated intelligence and police response. British intelligence infiltrated the Ghadarite movement in Canada and in India, and last minute intelligence from a spy helping to crush the planned uprising in Punjab before it started. Key figures were arrested, mutinies in smaller units and garrisons within India were also crushed.
Document 9: Niedermayer–Hentig Expedition: The Niedermayer–Hentig Expedition was a diplomatic mission to Afghanistan sent by the Central Powers in 1915–1916. The purpose was to encourage Afghanistan to declare full independence from the British Empire, enter World War I on the side of the Central Powers, and attack British India. The expedition was part of the Hindu–German Conspiracy, a series of Indo-German efforts to provoke a nationalist revolution in India. Nominally headed by the exiled Indian prince Raja Mahendra Pratap, the expedition was a joint operation of Germany and Turkey and was led by the German Army officers Oskar Niedermayer and Werner Otto von Hentig. Other participants included members of an Indian nationalist organisation called the Berlin Committee, including Maulavi Barkatullah and Chempakaraman Pillai, while the Turks were represented by Kazim Bey, a close confidante of Enver Pasha.
Document 10: Hindu–German Conspiracy: The Hindu–German Conspiracy was a series of plans between 1914 and 1917 by Indian nationalist groups to attempt Pan-Indian rebellion against the British Raj during World War I, formulated between the Indian revolutionary underground and exiled or self-exiled nationalists who formed, in the United States, the Ghadar Party, and in Germany, the Indian independence committee, in the decade preceding the Great War. The conspiracy was drawn up at the beginning of the war, with extensive support from the German Foreign Office, the German consulate in San Francisco, as well as some support from Ottoman Turkey and the Irish republican movement. The most prominent plan attempted to foment unrest and trigger a Pan-Indian mutiny in the British Indian Army from Punjab to Singapore. This plot was planned to be executed in February 1915 with the aim of overthrowing British rule over the Indian subcontinent. The February mutiny was ultimately thwarted when British intelligence infiltrated the Ghadarite movement and arrested key figures. Mutinies in smaller units and garrisons within India were also crushed.
Document 11: Congress Radio: Congress Radio was a clandestine and underground radio station, which operated for about three months during the Quit India Movement of 1942, a movement launched by Gandhi against the British Raj for independence of India. Congress Radio was the broadcasting mouthpiece of the Indian National Congress, and functioned from different locations from Bombay, currently known as Mumbai. It was organized by Usha Mehta (1920–2000), a veteran freedom fighter of India with the help of ham radio operators. Her other associates for organizing the Congress Radio included Vithalbhai Jhaveri, Chandrakant Jhaveri, and Babubhai Thakkar. The technicians and the equipment were supplied by Nanak Motawani of "Chicago Radio", Mumbai. Eminent personalities like Ram Manohar Lohia, Achyutrao Patwardhan, and Purushottam Trikamdas were also associated with the Congress Radio.
Document 12: MI5: The Security Service, also MI5 (Military Intelligence, Section 5), is the United Kingdom's domestic counter-intelligence and security agency and is part of its intelligence machinery alongside the Secret Intelligence Service (MI6), Government Communications Headquarters (GCHQ) and Defence Intelligence (DI). MI5 is directed by the Joint Intelligence Committee (JIC), and the service is bound by the Security Service Act 1989. The service is directed to protect British parliamentary democracy and economic interests, and counter terrorism and espionage within the UK.
Document 13: Special Bureau for India: Sonderreferat Indien, variously translated into English as, Special Bureau for India, Special India Bureau, or Section for Indian Affairs, was a section or bureau established within the Information Department of the Foreign Office of Nazi Germany in late spring 1941 in response to a proposal or memorandum written by the Indian nationalist Subhas Chandra Bose, who had arrived in Germany in early April of that year. The main function of the bureau was to aid Bose in his work, to liaise with Bose, and to mobilize an Indian Legion, comprising Indian POWs captured by Erwin Rommel's Afrika Korps, to aid the German military in a future land invasion of India. A military "intervention" in India, one of the two major points in Bose's proposal, had at first received a lukewarm response from the German Foreign Minister Joachim von Ribbentrop, but shortly afterwards it received the unexpected support of Adolf Hitler, who saw the battle for India as the natural aftermath of a successful German invasion of Russia and a chance to deliver the ultimate blow to the British Empire.
Document 14: British intelligence agencies: The Government of the United Kingdom maintains intelligence agencies within several different government departments. The agencies are responsible for collecting and producing foreign and domestic intelligence, providing military intelligence, performing espionage and counter-espionage. Their intelligence assessments contribute to the conduct of the foreign relations of the United Kingdom, maintaining the national security of the United Kingdom, military planning and law enforcement in the United Kingdom. The three main agencies are the Secret Intelligence Service (MI6), the Security Service (MI5), and the Government Communications Headquarters (GCHQ).
Document 15: Oster Conspiracy: The Oster Conspiracy of 1938 was a proposed plan to overthrow German "Führer" Adolf Hitler and the Nazi regime if Germany went to war with Czechoslovakia over the Sudetenland. It was led by Generalmajor (major general) Hans Oster, deputy head of the "Abwehr" and other high-ranking conservatives within the Wehrmacht who opposed the regime for its behaviour that was threatening to bring Germany into a war that they believed it was not ready to fight. They planned to overthrow Hitler and the Nazi regime through a planned storming of the Reich Chancellery by forces loyal to the plot to take control of the government, who would either arrest or assassinate Hitler, and restore the exiled Wilhelm II as Emperor.
