1. Context & Foundation

The origin of the Indian National Army (INA)β€”also known as the Azad Hind Faujβ€”stands as one of the most remarkable chapters of the subcontinental freedom struggle, representing a dramatic shift from non-violent constitutional agitation to organized, external military resistance. The geopolitical catalyst for this movement was the outbreak of the Second World War in Europe in 1939 and its subsequent expansion into the Asia-Pacific theater in December 1941, following Japan's surprise attack on Pearl Harbor.

As the Imperial Japanese Army launched its lightning offensive through Southeast Asia, the British defenses in Malaya and Singapore crumbled rapidly. The British military administration, demonstrating an inability to defend its Far Eastern colonies, retreated hastily, leaving behind tens of thousands of Indian soldiers of the British Indian Army as Prisoners of War (POWs).

To the Japanese military command, this massive pool of captured Indian soldiers represented a unique strategic opportunity. The Japanese sought to dismantle British imperial hegemony in Asia by encouraging and collaborating with native anti-colonial movements. To execute this liaison, Japanese intelligence officer Major Iwaichi Fujiwara established a dedicated operative wing called the F-Kikan.

The F-Kikan established contact with Giani Pritam Singh, an expatriate Indian nationalist and leader of the Indian Independence League (IIL) in Malaya. Together, Fujiwara and Pritam Singh targeted Captain Mohan Singh, a captured officer of the 1/14th Punjab Regiment of the British Indian Army. They persuaded him that rather than remaining as prisoners of a foreign power, the captured Indian soldiers should unite to form a liberating army to march on India and secure absolute Purna Swaraj.

This ideological appeal found immediate traction. Captain Mohan Singh, moved by intense patriotic fervor and a deep-seated resentment of British racial discrimination within the army, agreed to collaborate. This set the stage for the First Phase of the INA in 1942β€”a unique but volatile military experiment that highlighted both the immense potential of external armed resistance and the deep strategic tensions of collaborating with an expansionist imperial power like Japan.


2. Detailed Study Notes

Big Picture Overview

The development of the First Phase of the Indian National Army (INA) in 1942 progressed through four distinct phases, shifting from initial wartime liaison to institutional organization, combat mobilization, and eventual command conflict:

  1. The Japanese Liaison Phase (December 1941 – March 1942)

    • Main emphasis: The capture of British Far Eastern territories and the recruitment of Captain Mohan Singh by Major Fujiwara and Giani Pritam Singh.
    • Key Outcome: Convinced captured Indian POWs to channel their military capabilities toward national liberation rather than remaining in colonial captivity.
  2. The Institutionalization Phase (March–June 1942)

    • Main emphasis: Establishing the political and representative framework of the movement through high-level conferences in East Asia.
    • Key Outcome: The Tokyo and Bangkok Conferences formalizing the Indian Independence League under the presidency of Rash Behari Bose.
  3. The Military Mobilization Phase (September 1942)

    • Main emphasis: Organizing the first official combat division of the INA under the command of Captain Mohan Singh.
    • Key Outcome: Raising a disciplined force of over 16,300 active soldiers, ready to assist the Axis powers in liberating the Indian mainland.
  4. The Strategic Collapse Phase (December 1942)

    • Main emphasis: Severe command disputes between Mohan Singh and the Japanese authorities over the independent status and control of the army.
    • Key Outcome: The arrest of Captain Mohan Singh and the formal dissolution of the first division of the INA.

Major Topic: The Genesis and the Japanese Liaison

The military disaster suffered by the British in the Malayan Campaign created the direct material basis for the raising of the INA:

1. The Fall of Singapore (February 1942)

  • The Scale of Capture: Following the humiliating surrender of the British forces at Singapore on February 15, 1942, approximately 45,000 Indian soldiers were taken as Prisoners of War by the Japanese forces.
  • The Transfer of Command: In a formal ceremony held at Farrer Park in Singapore, the British representative, Colonel Hunt, officially handed over the Indian POWs to the Japanese military command. The Japanese, in turn, handed over the custody of these soldiers to Captain Mohan Singh, designating him as their commander and supervisor.

2. The Role of Major Fujiwara and Pritam Singh

  • Major Iwaichi Fujiwara: Headed the Japanese intelligence organization F-Kikan. Fujiwara was a political realist who believed that Japan's "Pan-Asian" vision could be achieved by supporting Indian independence, thereby neutralizing British military capabilities.
  • Giani Pritam Singh: A radical Sikh missionary and nationalist who operated the All-Malayan Indian Independence League. He acted as the critical intermediary, using his local network to distribute anti-British literature and persuade the captured sepoys to join the nationalist cause.

Major Topic: The Constitutional Conferences of 1942

To provide the military movement with political legitimacy and a representative civilian body, veteran revolutionary Rash Behari Bose (who had lived as a political fugitive in Japan since 1915 following the failed Ghadar Mutiny) stepped forward to organize the East Asian Indian diaspora:

1. The Tokyo Conference (March 1942)

  • The Objective: To bring together various Indian expatriate groups residing in Japan, Malaya, Siam (Thailand), and Burma to establish a unified political program.
  • Key Achievements:
    • Resolved to establish the All-India Independence League (IIL) as the supreme civilian body to direct the liberation struggle.
    • Decided to raise the Indian National Army under the direct command of Captain Mohan Singh.
  • The Apprehensions: Many delegates at the conference expressed deep skepticism and fear regarding the ultimate motives of the Japanese government, worrying that Japan might use the INA as a mere political tool or "puppet force" to replace British rule in India with Japanese imperialism.

2. The Bangkok Conference (June 1942)

  • The Leadership: Chaired officially by Rash Behari Bose, who was elected as the President of the Indian Independence League.
  • The Resolutions: The conference passed a comprehensive 34-point resolution outlining the terms of collaboration with Japan:
    • Demanded that the Japanese government explicitly recognize India as an independent, sovereign nation post-liberation.
    • Demanded that the Japanese recognize the Indian Independence League as the sole representative and guardian of the Indian people in East Asia.
    • Insisted that the INA must be recognized as an Allied army, and all captured Indian POWs must be unconditionally handed over to its command.
    • Formally invited Subhas Chandra Bose (who was then in Berlin) to East Asia to assume the supreme leadership of the movement.

Major Topic: The First Division of the INA (September 1942)

  • The Proclamation: On September 1, 1942, the first division of the Indian National Army was officially raised in Singapore, consisting of 16,300 highly trained soldiers organized into combat units.
  • The Motivation: The recruitment of these soldiers was driven by a complex mix of anti-British nationalist sentiments, the desire to escape the harsh conditions of Japanese POW camps, and the confidence inspired by Captain Mohan Singh’s leadership.
  • The Role of the Ghadarites: Expatriates who had been associated with the early Ghadar Movement of 1913 (such as Baba Gurmukh Singh and Kartar Singh Sarabha's early networks) actively supported the mobilization, viewing the INA as the ultimate fulfillment of their early dream of an armed overthrow of the Raj.

Major Topic: The Conflict and the Dissolution (December 1942)

The collaboration between Captain Mohan Singh and the Japanese military authorities was short-lived, breaking down due to irreconcilable strategic and operational disputes:

1. The Core Areas of Friction

  • The Control over POWs: Captain Mohan Singh wanted to expand the INA into a massive force of over 40,000 soldiers by recruiting all available Indian POWs. The Japanese military, however, refused to release more prisoners, wanting to keep them as a source of manual labor to construct military infrastructure (such as the Siam-Burma railway).
  • The Question of Independent Command: Mohan Singh insisted that the INA must operate as a completely independent allied army under Indian command. He vehemently refused to allow the Japanese to utilize Indian troops as mere auxiliary forces or guide units under Japanese officers on the Burma front.
  • The Status of the 34-point Resolution: The Japanese government deliberately delayed giving a formal, public reply to the Bangkok Conference’s 34-point resolution, refusing to officially commit to India’s absolute post-war sovereignty.

2. The Final Breakdown (December 1942)

  • The Arrest: When Captain Mohan Singh openly defied Japanese orders and threatened to disband the INA if his demands for independence were not met, the Japanese military authorities took decisive action. In December 1942, Captain Mohan Singh was arrested and deported to a remote island.
  • The Dissolution: Following his arrest, the first division of the INA was formally dissolved. The soldiers were stripped of their weapons and sent back to POW camps, marking the temporary collapse of the first phase of the military movement.
  • The League's Custody: To prevent the complete disintegration of the anti-colonial network, Rash Behari Bose took temporary charge of the remnants of the INA, keeping the organizational framework of the Indian Independence League intact until the arrival of Netaji Subhas Chandra Bose in 1943.

Do Not Confuse

SPSC and state-level exams frequently design tricky questions to confuse the distinct phases, conferences, and leaders of the INA. Study this comparative grid to secure full marks:

1. The Two Phases of the Indian National Army

FeatureThe First Phase of the INA (1942)The Second Phase of the INA (1943–1945)
Primary CommanderCaptain Mohan Singh (Commander-in-Chief).Netaji Subhas Chandra Bose (Supreme Commander).
Civilian Controlling BodyIndian Independence League (led by Rash Behari Bose).Provisional Government of Free India (Azad Hind Sarkar).
HeadquartersLocated primarily in Singapore.Headquartered in Singapore and Rangoon (Burma).
Sovereignty StatusHighly dependent on Japanese goodwill; lacked official international recognition.Functioned as a sovereign government-in-arms; recognized by nine sovereign nations (including Germany, Italy, and Japan).
Key Military CampaignDid not launch any major offensive; dissolved before combat deployment.Launched the historic Imphal-Kohima Campaign (1944) on the Indian mainland.
OutcomeDissolved in December 1942 following Mohan Singh's arrest.Surrendered in August 1945 following the surrender of Japan and Netaji's reported death.

Core Difference: The First Phase of the INA (1942) was a preliminary military experiment led by Captain Mohan Singh that collapsed due to command disputes with Japan, whereas the Second Phase (1943) was a sovereign, mass-mobilized national army led by Subhas Chandra Bose that executed a full-scale military campaign on Indian soil.


2. The East Asian Constitutional Forums (1942)

FeatureThe Tokyo Conference (March 1942)The Bangkok Conference (June 1942)
LocationTokyo, Japan.Bangkok, Siam (Thailand).
Chaired ByRash Behari Bose (with Japanese military support).Rash Behari Bose (elected as President of the IIL).
Key DecisionResolved to form the Indian Independence League and raise the INA.Adopted the historic 34-point resolution defining the terms of collaboration with Japan.
Bose's InvitationMade early proposals to contact Subhas Chandra Bose in Berlin.Officially invited Subhas Chandra Bose to East Asia to assume the supreme leadership.

Core Difference: The Tokyo Conference was an exploratory forum that established the intent to raise the INA, while the Bangkok Conference was a formal constitutional forum that drafted the 34-point resolution and invited Subhas Chandra Bose to take command.


MCQ Traps

  • The "First Commander" Match: SPSC papers frequently try to include Subhas Chandra Bose as the first commander or founder of the INA. This is false. The first division of the INA was raised and commanded by Captain Mohan Singh in September 1942. Subhas Chandra Bose took command only in July 1943.
  • The "Solely Indian POWs" Fallacy: Watch out for statement-based questions claiming that the INA consisted solely of Indian Prisoners of War. While the first phase was comprised primarily of POWs, the second phase under Netaji recruited thousands of civilian volunteers from the Indian diaspora in Malaya, Singapore, and Burma.
  • The "34-point Resolution Approval" Trap: SPSC options often claim that the Japanese government immediately accepted and signed the 34-point resolution of the Bangkok Conference. This is false. The Japanese deliberately delayed and avoided signing the resolution, which was the primary cause of friction and the subsequent arrest of Mohan Singh.
  • Rash Behari Bose vs. Rash Behari Ghosh: Ensure you read spelling-based match-the-following options carefully. Rash Behari Ghosh was the moderate Congress President who presided over the historic Surat Split of 1907, while Rash Behari Bose was the veteran revolutionary who organized the Ghadar Mutiny, fled to Japan in 1915, and founded the Indian Independence League in 1942.

Telangana / Hyderabad State Connection

The wartime recruitments of the Second World War and the raising of the INA in Malaya had direct, corresponding developments within Hyderabad State and the Telangana region under Nizam VII, Mir Osman Ali Khan:

                     joining the INA's first division to fight for Purna Swaraj.
  • Deccan Soldiers in the Malayan Campaign: SPSC and TSPSC aspirants must note the direct military link. Under the terms of British paramountcy, the Nizam, Mir Osman Ali Khan, dispatched native state troopsβ€”most notably the 1st Hyderabad Imperial Service Lancers and selected infantry unitsβ€”to serve on the Malayan and Singapore fronts under British command. When Singapore fell to the Japanese in February 1942, several Telugu-speaking and Deccani soldiers from Telangana were captured as Prisoners of War.
  • Telangana POWs Joining the First INA: Exposed to the patriotic appeals of Giani Pritam Singh and the direct command of Captain Mohan Singh, many of these captured Telangana soldiers made a radical political choice. They renounced their oath of loyalty to the Nizam and the British Crown, volunteered to join the first division of the INA, and took up arms to secure the liberation of their motherland.
  • The Nizam’s Crackdown on Pro-INA Sentiments: The news of native Deccan soldiers joining an anti-British military force in Singapore provoked deep panic within the Nizam's administration. The Hyderabad state police and CID enforced strict surveillance on the families of these soldiers in the interior districts of Telangana (such as Warangal, Nalgonda, and Hyderabad). Any display of sympathy toward the INA or Netaji's early broadcasts was treated as a severe act of treason, with the Nizam's court confiscating the family lands and pensions of those soldiers who had joined the liberation army. This administrative high-handedness further intensified the anti-feudal and anti-colonial resistance of the Deccan peasantry.

4. Exam Strategy & PYQ Focus

High-Yield Focus Areas

VERY HIGH PRIORITY

  • The First Commander's Identity: TSPSC and state civil service exams consistently target this detail. Ensure you memorize that Captain Mohan Singh was the first commander of the INA in September 1942, not Subhas Chandra Bose.
  • The "Bangkok Conference" Year and Chair: SPSC papers frequently ask who chaired the Bangkok Conference of June 1942. It was Rash Behari Bose, who was also elected as the President of the Indian Independence League.
  • The Reason for Mohan Singh's Arrest: SPSC statement-based questions target this operational friction. Memorize that Mohan Singh was arrested because he demanded complete independent command and refused to allow the Japanese to use the INA as a puppet auxiliary force.

HIGH PRIORITY

  • The F-Kikan Organization: Note that the Japanese intelligence organization responsible for collaborating with Indian nationalists was headed by Major Iwaichi Fujiwara.
  • The 1/14th Punjab Regiment Match: SPSC "Who's Who" matching questions regularly ask for Captain Mohan Singh's parent regiment. Always pair him with the 1/14th Punjab Regiment of the British Indian Army.

MODERATE PRIORITY

  • The Role of Giani Pritam Singh: Remember that the Indian Independence League leader who acted as the critical intermediary in Malaya was Giani Pritam Singh.

What to Skip / Low-Yield

  • Deep, microscopic tactical details regarding the exact ammunition calibers utilized by the 1/14th Punjab Regiment during the retreat at Jitra.
  • Detailed personal itineraries of the Japanese military staff assistants who accompanied Major Fujiwara to Bangkok.

How to Study This Topic

  1. Construct a "First Phase of INA Timeline": On a single sheet of paper, sketch out a linear vertical flowchart tracing: \[\text{Fall of Singapore (Feb 1942)} \rightarrow \text{Tokyo Conference (Mar 1942)} \rightarrow \text{Bangkok Conference (June 1942)} \rightarrow \text{First INA Division Raised (Sept 1, 1942)} \rightarrow \text{Mohan Singh arrested & INA dissolved (Dec 1942)}\] This sequential roadmap is the most effective way to eliminate chronological-ordering questions.
  2. Tabulate Tokyo vs. Bangkok Conference Provisions: Create a simple two-column study card contrasting the decisions of the Tokyo Conference (exploratory, formed IIL) with the Bangkok Conference (34-point resolution, invited Subhas Bose) to eliminate statement-based SPSC options easily.

5. Chronology & Broader Context (Past β†’ Present β†’ Future)

Pre-context

Prior to the raising of the first division of the INA in 1942, the national movement was locked in a quiet deadlock within the subcontinent. The Congress provincial ministries had resigned en masse in late 1939 in protest against India's forced entry into World War II, and Mahatma Gandhi had led a highly disciplined, limited Individual Satyagraha campaign in 1940–1941. However, these peaceful protests did not force the British government to yield any real political concessions. The sudden advance of Japanese forces in Southeast Asia and the fall of Singapore in early 1942 shattered this quiet phase, creating a massive pool of captured Indian soldiers and presenting Indian revolutionaries in exile with a golden opportunity to organize an armed struggle.

Concurrent Events

  • The Quit India Movement (August 1942): Raging concurrently within India, the arrest of the top Congress leadership under Operation Zero Hour unleashed a massive, spontaneous mass upsurge, providing immense moral encouragement to Captain Mohan Singh's soldiers in Singapore, who viewed their military mobilization as the armed wing of the domestic rebellion.
  • The Siam-Burma Railway Construction (1942): Developing concurrently, the Japanese military forced hundreds of thousands of Asian laborers and Allied POWs (including many non-cooperating Indian soldiers) into the brutal construction of the Siam-Burma "Death Railway," highlighting the oppressive, imperialist nature of the Japanese occupation.

Post-context

The collapse of the First Phase of the INA and the arrest of Captain Mohan Singh in late 1942 did not mark the end of the military movement. Rash Behari Bose successfully preserved the organizational framework of the Indian Independence League, paving the direct path for the arrival of Subhas Chandra Bose in July 1943. Netaji took command, transformed the remnants into a sovereign, mass-mobilized national army, and launched the historic Imphal-Kohima Campaign in 1944. Ultimately, the subsequent Red Fort INA Trials of late 1945 and the Royal Indian Navy Mutiny of 1946 broke the military backbone of the British Empire, forcing the final transfer of power in August 1947.
