GOPĀL, RĀJĀ (Rāj Siṅgh according to some sources), of Guler, mentioned in Sikh chronicles as well as in Gurū Gobind Siṅgh's Bachitra Nāṭak, was one of the hill chieftains who fought against the Gurū in the battle of Bhaṅgāṇī in 1688. After the defeat of the rājās, Gopāl seems to have sought peace and friendship with Gurū Gobind Siṅgh. When Husain Khān was despatched in 1696 by Dilāwar Khān, the Mughal chief, towards the hills to chastise the recalcitrant princes, Rājā Gopāl, not being able to pay the heavy tribute levied upon him, prepared to fight. He was helped by his ally, Rājā Rām Siṅgh of Jasvān. Saṅgatīā and seven other Sikhs who had come as an embassy of peace to the court of Rājā Gopāl also took part in the battle. In the fierce action (20 February 1696) that ensued, Husain Khān was slain and Rājā Gopāl and his allies won a decisive victory. Saṅgatīā and his seven Sikhs fell fighting the Mughals. Rājā Gopāl celebrated the triumph by making offerings to Gurū Gobind Siṅgh and rendering him gratitude.
