I know where this story comes from, it comes from a guy named Neeraj Atri who, a physics teacher (like me), turned into a historian delving into history that is not taught in schools but is hidden under archives of systemic bankruptcy of values and morals.
The history of India or Bharat that was never told among Balbans, Victorias, Marxs, Nehrus and Gandhis. The true history of Sambajis, Laxmibais, Savarkars, Pathas etc who sacrificed their lives and more for this land they called their mother because they if could do more, they would have done it.
The history with real proof and not a mere footnote that it was a manifestation of a leftist's dream of how Bharat should be and not how it really was.
The real history not from the eyes of the invader but those who lived on to protect what was their and was handed over to them from their ancestors, from Ram, Krishna etc. A true history to be proud of.
