The remains of warriers are preserved in the War Memorial.

Thanks Topoffer, in the 2nd World War, Japan, Germany and Italy were against the British camp. When Netaji Subhash Chandra Bose made his Indian National Army with Indians in foreign countries, they did not have resources to fight the British army. So he took the help of the Japanese soldiers, because Germany and Italy war far away from India. Strategically it was not possible to get their help.

The Japanese Imperial army was already far stretched and too thinly spread and I doubt they would be able to colonize a country the size of India, the best they would be able to do is to set up a puppet government similar to the Philippines. Remember a large part was inside their mortal enemy China. For them to colonize India, China and South east Asia is unthinkable. In the Philippines the best they achieved was occupy, and only major provinces, towns and cities while fighting a protracted never ending guerilla warfare in jungles of every island, it exhausted and delayed them so much they had second thoughts about Australia The scenario in British Malaya was different, there was lesser resistance after the British capitulated.

@louievill You do not often need many people to colonize a place. It would require some investigations, but I suppose that there were more Indian soldiers in the British army than British soldiers in India. It is not something new, it was already happening during the Antiquity. When you look at the Roman Empire, you realize that the Romans would not have been enough to govern on all countries surrounding the Mediterranean Sea. The majority of the Roman army was not Roman. We think now that the Celts were only little groups of people when they were invading a new country. They were sending maybe only 20 or 30 warriors to colonize. Or the people living their were adopting their civilization, which was technically more advanced, or the Celts were killed. And for guerillas in Philippines, you have always had guerillas, like we always had independentists in Corsica.

Thanks Louievill, yes had the Indian National Army received support of Japanese army, India might have got independence with the hands of Netaji Subhash Chandra Bose before 1947.

Thanks Prashuji happy bijoya dashami.
