The film Kesari is based on the true incidence of Battle of Saragarhi fought in 1897. Havildar Ishar Singh, a soldier of the British Indian army was posted at Gulistan fort along the Indo-Afghan border. Ishar saw group of Afghan led by Mullah Saidullah trying to kill a married woman who did not acknowledge her forced marriage. The inner quality of humanity made Ishar rescue the woman by disobeying the order of his superior. He was transferred to Saragarhi fort. He not only enabled discipline among the troops there but also earned their respect due to his caring attitude. Colonel John Haughton saw huge Afghan forces marching towards Saragarhi so ordered Ishar to abandon the fort. Ishar and his men decided to fight till their death which resembles their responsible attitude. Ishar ordered Gurmukh Singh, an inexperienced soldier to keep the commanding officer informed about the battle and decided to prolong the battle to stop Afghans from advancing Gulistan and Lockhart fort. This resembles Ishar's shrewed intelligence. Afghans destroyed the backwall of the fort. Ishar fought with a red-hot sword. His bravery impressed an Afghan chief and ordered his men not to touch a Sikh's turban before killing him. As the post was lit on fore, Gurmukh Singh emerged as a brave soldier with his body on fire, grabbed Gul Badshah and triggered grenades attached to his body resulting in huge explotion. The British parliament honoured the martyrs. The film is full of nostalgia and one would like the action present in the film..
