During the dewani of Dewan Shahbaz Khan in 1650, the Hatirpul was constructed. It was a bridge built over the canal mainly for elephant pass. The Mughal dewans used to communicate by the elephant in this road and also took rest near this bridge. In 1662, the Arifil Mosque was constructed by Shah Arif. There are unknown tombs located near the mosque, supposedly belonging to the wives of Isa Khan. During the Bangladesh Liberation War of 1971, the Pakistani Army killed about 70 innocent people in the Bitghar area. On 5 May, the freedom fighters raided the Pakistani Army's camp in the Shahbazpur area and killed 9 Pakistani soldiers; one freedom fighter was killed during this raid. A number of Pakistani Army officers and the chairman of the Sarail Peace Committee were also killed. The freedom fighters set up a mine bomb north of Kalikaccha Bazar. This exploded and destroyed two military vehicles. Three mass graves remain in Sarail.
