Ajay Devgn took to Twitter and revealed the first poster saying "Unveiling @SonsOfSardaar My tribute to Warriors of Saragarhi: A tale of Rage, of Love, of Bravery. #SonsOfSardaar"

'Sons of Sardaar' is the story based upon the 21 Sikhs who fought to death in the 1897 Battle of Saragarhi.

Currently Ajay is busy with 'Shivaay' which is slated to release on Diwali this year. He will begin shooting for 'Sons of Sardar: Battle of Saragarhi' after completing Shivaay.
