Freedom isn't free! Sikh Martyrs and Indian Freedom fighters.

Wish all of my Sikh brothers and sisters a Happy Gurpurab on the birth of our true satguru sache patshah, Guru Gobind Singh Ji. I hope people remember the sacrifices of our great Gurus, Khalsa Singhs and Kaurs and other great freedom fighters who sacrificed so much so that people like me can live a life, free of slavery, tyranny and aggression. Oh! there is so much we have to be thankful for and God bless these great souls! I wonder, how many Indians or even Punjabi Sikhs and Hindus of today even know about these great men, women and children of courage? Are they even mentioned in the text books of India?
