According to Chapter 15 of the History Paper-I, Landmarks in World History:
"Bhagat Singh, Rajguru and Sukhdev were hanged for killing the British. The government put severe measures to curb this freedom movement. However, terrorist activities continued in Bengal and Maharashtra."
Since history is written from the perspective of the person writing history do we we conclude that this text is the work of a British author? Or maybe the Mumbai University feels that India never won its freedom from the British.
Incidentally, the same text says "the Sikh community and the depressed classes did not take part in the Quit India Movement."
