The date of 7 April was fixed, then why was Mangal Pandey hanged on 8 April?:

So many freedom fighters happily sacrificed their lives so that the future generations of the country can breathe in free air. 8th April is dedicated to them. Mangal Pandey, who lit the flame of freedom for the first time in the country in 1857, was hanged on 8th April. But let us tell you that 8th April would not have been recorded as the last day of Mangal Pandey in the pages of history, if on 7th April the executioners did not know who was to be hanged.

The dilemma faced by the British

Actually, 18 April 1857 was the date fixed for Mangal Pandey's hanging, but seeing the danger of rebellion and incitement, the British wanted to hang him a few days earlier on 7 April, but could not. Mangal Pandey Vichar Manch spokesperson Babban Vidyarthi has written that in the early hours of 7 April, two executioners were called to hang Pandey in the Barrackpore cantonment, but as soon as they came to know that Pandey was to be crucified, they refused to hang him.

The executioner was also impressed by Mangal Pandey's patriotism. After this, when the British were in a dilemma, the executioner was called from Calcutta, but due to the delay in his arrival, Pandey could be hanged the next day on the morning of 8 April in the parade ground of Barrackpore.

Bhagat Singh had challenged the British rule

The day of 8th April is recorded in the history of people who sacrificed their lives for freedom. Another incident is also associated with this day. Freedom fighters like Bhagat Singh and Batukeshwar Dutt threw a bomb in Delhi's 'Central Assembly Hall' on 8th April 1929. The purpose of this bomb blast was not to harm anyone but to draw the world's attention towards India's freedom movement.
