Q. Which Mughal general joined the Sikhs at the First Battle of Chamkaur (1702)?
Answer: Sayyad Beg
Notes: In 1702, Mughal General Sayyad Beg defected to the Sikh side at Chamkaur. His defection, during Guru Gobind Singh's conflict with Mughal and Bilaspur forces, boosted Sikh strength significantly. The battle marked a key victory for the Sikhs against Mughal aggression.
