Gopal was the ruler of the small hill State of Guler (it was also known as Haripur). In 1696, when Hussaini attacked him to forcibly collect revenue from him, he sought the help of Guru Gobind Singh Sahib. Guru Sahib sent some Sikh soldiers under the leadership of Bhai Sangatia. The battle was fought at Guler, on February 18, 1696. In this battle Bhai Sangatia, Bhai Darso and seven more Sikhs embraced martyrdom. In this battle Ajmer Chand Kehluria (Bilaspuri) fought on the side of the Moguls. Since this battle Ajmer Chand became enemy of the Sikhs.
