Netaji appears in Singapore
a) Nominated as President of IIL ; On 27th June Subhas Chandra Bose and Rash Bihari Bose arrived in Singapore,which used to be the British stronghold and was enthusiastically welcomed by the leaders of the IIL, The INA as well as a large number of Indian Nationals residing in the city. Among those present were also representatives of the  Japanese army Command and the Hikari Kikan.
After the main issue was settled Netaji decided to form a Brigade known as No I Guerilla Regiment, by selecting the soldiers from the three Brigades after Gandhi, Nehru and Azad which should go first into action and Shah Nawaz Khan was appointed its commander.

Taking over the helm of the Indian Independence movement Netaji inspected the INA on 5 July . For the first time he donned the Khaki uniform of the supreme commander of the INA for the first time, gave this army of liberation , the war cry of Chalo Delhi (Onward to Delhi).and he gave the assembled civilians the slogan of 'Total Mobilisation."

Khan, who rose to the rank of Captain in the Indian Army, was captured by the Japanese after the fall of Singapore in 1942. A prisoner of war in Singapore, he was profoundly influenced by Subhas Chandra Bose's speeches asking POWs to join the Indian National Army and to fight for a free India. He later stated:

"It will not be wrong to say that I was hypnotized by his personality and his speeches. He placed the true picture of India before us and for the first time in my life I saw India, through the eyes of an Indian."

Impressed by Bose’s patriotic speeches, Nawaz joined the INA in 1943. He was included in the Cabinet of the Arzi Hukumat-e- Azad Hind (INA) formed by Bose. Later, Bose decided to select a regiment consisting of the cream of the INA and send it to action to spearhead the advance into India. Khan led the army into North-Eastern India, seizing Kohima and Imphalwhich were held briefly by the INA under the authority of the Japanese. In December of 1944, Shah Nawaz Khan was appointed Commander of the 1st Division at Mandalay.
