A tranche of 50 declassified related to the 70-year-old mystery surrounding Netaji Subhas Chandra Bose were released on Tuesday by Culture Minister Mahesh Sharma. The files, which span the time period from 1956 to 2009, consist of 10 files each from the Prime Minister’s Office (PMO) and the Home Ministry and 30 files from the External Affairs Ministry. The recent declassification of files follows Prime Minister Narendra Modi's decision of releasing hundred secret files on Netaji's 119th birthday, ranging from those from the British Raj to as late as 2007, on January 23 this year. Here are some of the new revelations from the recently released files The most surprising revelations from the newly released files point out to the fact that Netaji might actually have survived the crash on August 18, 1945. According to various references in the documents, there is also a good amount of evidence that Bose outlived the crash. "PC Kar, an official in the governor’s house in Bengal when RG Casey was the governor, claimed that the monitoring service at the governor’s house picked up three broadcasts of Netaji on the 31 metre band in December 1945, and January and February, 1946. A note on this item was put up before Mr. Casey."

What were the three broadcasts?

According to page number 29 of the same file under the title of Netaji Subhas Chandra Bose's Broadcast after the alleged air crash, there are clear cut references to the speeches made by Bose after he was feared dead in a plane crash.

"I am at present under the shelter of great World powers. My heart is burning for India. I will go to India on the crest of a Third World War. It may come in ten years or even earlier. Then I will sit on judgment upon those trying my men at the Red Fort," reads one file dated December 26, 1945.

Some of the statements also point out to the difference in ideologies of Netaji and Mahatma Gandhi.

A file dated January 1, 1946 quotes Netaji saying: "We must get freedom within two years. The British imperialism has broken down and it must concede independence to India. India will not be free by means of 'non-violence'. But I am quite respectful to Mahatma Gandhi."

"The battle of freedom is not easy. But I can assure you that we will get freedom of India very soon. I know that many Indians are waiting for me. I am quite sure to be successful within two years."

Another file dated February 1946 contains his appeal to fellow Indian about the designs of British imperialism:

"This is Subhas Chandra Bose speaking, Jai Hind. This is the third time I am addressing my Indian brothers and sisters after Japan's surrender... The PM of England is going to send Mr Pethick Lawrence and two other members with no object in view other than let the British imperialism a permanent settlement by all means to suck the blood of India."

The same file also narrates a communication between one of the secretaries of Gandhi, Khurshed Naoroji to Louis Fischer (in reply to his letter to the Mahatma) in which he said: "At heart, the Indian Army is sympathetic to the Indian National Army (INA). If Bose comes with the help of Russia, neither Gandhiji nor Nehru nor the Congress will be able to reason with the country."

It also adds, "It is intriguing that almost a year after the reported air crash at Taihoku, Gandhiji's camp were apprehending Netaji's return to India from the Soviet Union instead of being convinced of his death."
