He was one of the youngest revolutionaries to be martyred for the nation's freedom struggle, being executed by the British colonial authorities when he was only 19, two months before his 20th birthday.

[3] Hemu Kalani was born in a Sindhi family[4] at Sukkur in Sind Division of Bombay Presidency in British India (now in Pakistan) on 23 March 1923.

He was drawn to revolutionary activities and started participating in acts of protests with the aim of driving out the British from the Indian subcontinent.

Hemu Kalani found out that a train of these troops and their supplies would be passing through his local town at the midnight of 22 October and decided to derail it by removing the fishplates from the railway track.

On the day of his execution, he appeared extremely overjoyed, and walked to the gallows with a copy of the Bhagavad Gita in his hands, smiling and humming the whole way.
