There were so many incidents before this 1857 mutiny, like
The Vellore Mutiny (July 10, 1806).
whats the point, we got independence only in 1947. There were so many different people who made sacrifice and fought for independence before and after this incident in 1857.
There is no point in trying to take credit for just one community exclusively, it has to be inclusive of every community and be thankful to all of them.
