In December 1941, after meeting with the Japanese commanding general, Rash Behari Bose was convinced of the feasibility of raising an armed Indian unit. Between himself, Rash behari Bose, Pritam Singh and Fujiwara, formulated plans of contacting Indians in the British Indian Army in South-east Asia. The fall of Malaya further brought under Japanese control approximately 45,000 regular Indian troops from
Gen. Percival's command in Malaya, including a large numbers of the remnants of the
Indian III Corps. Even before Singapore fell, the Japanese troops had started the process of identifying Indian troops among the captured and separating them from the Australian and British troops. On a number of occasions, it was noted, British and Australian officers were killed, while the Indians spared. Singh began recruiting from amongst these captured Indian soldiers. Thus the nucleus what came to be the Indian National Army was born. They were organised into units and trained and worked along with those already under Pritam Singh in
Malaya and
Thailand. They were further tasked to work amongst fighting British-Indian Army units to foment dissent and encourage defection. He invited the troops seated at the park to join this army. Further, he told the troops, they were going to be treated not as PoWs, but as friends and allies. Fujiwara ended his speech stating he is passing on their responsibilities and command to Mohan Singh. It is estimated that nearly half of those present at
Farrer Park later joined the first INA. Significantly however, a large number of Indian officers decided not to, which also kept those under their command disinclined. The Japanese forces, eager to engage the co-operation of the troops and further lacking the man-power, did not have the men impounded. The supreme command of the INA was set up at Mount Pleasant suburbs in the Northern part of Singapore. The PoW headquarters, along with the largest PoW camp was set up at Neesoon under
M. Z. Kiani. Other smaller PoW camps housing Indian troops were set up at Bidadari, Tyersall, Buller,
Seletar and
Kranji. To
Lt. Col N.S Gill went the overall direction of PoW. In contrast, the Indians received far more lenient treatment. However, this is not to say that the Indians felt no fear at all. In fact, the attitudes of the Japanese forces towards the Chinese population did instill some fear in the general Indian civilian population as well as leaders such as Pritam Singh. This was significant or the Indian leaders, during the Farrer Park meeting who had expressed reservations about collaborating with the Japanese as these incidents further cemented their initial beliefs about the cruel nature of the Japanese and would further affirm their decision to not join the INA in May 1942. K.P.K Menon, Nedyam Raghavan were civilian members among the civilian members of the council while Mohan Singh and an officer by the name of Gilani were to be the INA's members.
Autumn 1942 On the back of the success of the INA, Fujiwara suggested in January 1942 expanding the work of the F-Kikan to all parts of Asia. The Iwakuro Kikan (I-Kikan) was considerably larger, with some 250 officers and with offices in
Rangoon,
Penang,
Saigon and Hong Kong. Iwakuro, the founder of the Army intelligence school
Rikugun Nakano Gakko, was aware that the
IGHQ did not have immediate plans to invade India. Some historians suggest the intelligence services played a significant role in the failure of
Noel Irwin's
First Arakan Offensive. Earnest organisation of the INA in preparation for the battle began after news of
Quit India had reached South-east Asia. This uprising within India was taken to be the signal from Congress and Indian people that the INA and the league had been waiting for. Iwakuro visited Tokyo in August 1942, and on his return had expected to train and equip 15,000 men over three months. These men were to be moved to Burma in stages to avoid concentrating in Singapore. The British-Indian army sub-unit structure was preserved to hasten operational deployments. Almost 16,000 men comprised this first division of the INA. According to the reviews available, the INA was to be organised of twelve infantry battalions of 650 troops, organised into four
guerrilla regiments of 2000 men. Battalion and regimental commanders were appointed on 5 September, and assumed their commands on 8 and 9 September. A few days later it was reviewed by
Rash Behari Bose and Mohan Singh. The first of these was the Hindustan Field Force, under the command of
J.K. Bhonsle. The unit was formed at Singapore and comprised three battalions derived from troops of the
17th Dogra Regiment,
Garhwal Rifles and the
14th Punjab Regiment (now a part of the
Pakistani Army) and had a strength of nearly 2000 troops. The Hindustan Field force was also to include a heavy gun battalion, a company each of transport corps, signal corps, engineering corps and a company of medical corps. An additional Special Services Group was intended for long-range infiltration, and a reinforcement group to promote defection amongst the British Indian Army and recruit new members from PoWs. 50 officers and nearly 24,000 men were "surplus volunteers". Armament consisted of 5000 rifles, 250 light machine-guns, 500 sub machine-guns, 30 cars and 50 lorries. Both Hugh Toye and Joyce Lebra conclude in their research that Gill was, in fact, intending to escape back to commonwealth forces also. However, he was summoned back from Burma to Singapore by this time in November. Other members of the Indian Council also voiced their concerns and displeasure at what was seen as Japanese intrusion into INA's work. Raghavan, in charge of
Swaraj schools training intelligence and espionage agents in Singapore, was enraged to find a number of his students dispatched to India without his approval or permission. Japanese efforts to censor Indian broadcasting in Singapore also brought forth rank disagreements which had culminated in the arrest of the Indian director of broadcasting. In addition to this, non-committal replies from Japan on the points raised by the council for action in the
Bangkok resolutions raised the ire of Mohan Singh and League members. The final straw to this was a report to the council by an officer of the situation in Burma, where Japanese military administration refused or prevaricated to handover abandoned Indian property to the league, as demanded n the Bangkok resolutions. A group of Japanese officers meeting league members had very candidly declined to attach any importance to the Bangkok resolutions or to Indians. Amidst worsening tensions, a repeated attempt by the council for action to obtain Japanese reassurance and commitment was rebuffed by Iwakuro. By November, Mohan Singh and K.P.K. Menon refused to send a previously planned batch of INA soldiers to Burma, with the council for action rallying behind them. Despite
Rash Behari Bose's attempts to smooth over differences between the INA and Japanese, a second demand for 900 INA men by the Japanese was refused. This was followed by a Japanese attempt to take command of Indian troops who had not enlisted in the INA, who had so far been under the custody of INA. In December N.S. Gill was arrested from Mohan Singh's home in Singapore, precipitating resignations of both the INA command and members of the council for action, along orders from Mohan Singh for the INA to disband. Mohan Singh was subsequently arrested by the Japanese and exiled to
Pulau Ubin. A number of the Indian troops who chose to revert to PoW were subsequently sent away to labour camps in
New Guinea or to work in the
Death railway. Between December 1942 and February 1943,
Rash Behari Bose tried but failed to keep the IIL and INA going. Thousands of INA soldiers returned to the status of POWs(prisoners of war) again and most of the IIL leaders resigned. ==Operations involving the first INA==
