On 12 September 1897, 21 soldiers of 36th Sikh regiment stood undeterred as they guarded the post of Saragarhi against the onslaught of almost 10,000 Afghan tribesmen – a battle for the ages that ended in them laying down their lives in the line of duty. Based on colonial era records and information provided by the 4th Sikh Battalion: Regiment, '21 Kesaris' attempts to answer these questions while paying homage to the brave soldiers who defended the kesari flag – depicting their Khalsa heritage – with their last breaths.
