Bibi Sahib Kaur (1771-1801) was a warrior and leader of men who played a prominent part in the history of the Sutlej states from 1793 to 1801, was the elder sister of Raja Sahib Singh of Patiala. Born in 1771, Sahib Kaur was married at an early age to Jaimal Singh of the Kanhaiya clan, who resided at Fatehgarh and was master of a greater part of the Bari Doab above Dina Nagar in present-day Gurdaspur district of the Punjab. In 1793, Raja Sahib Singh, in view of mounting dissensions within his state, recalled his sister Blbl Sahib Kaur to Patiala and entrusted to her the of fice of prime minister. She had not been long in Patiala when she had to return to Fatehgarh at the head of a large Patiala army to rescue her husband who had been captured by Fateh Singh, a rival chief. Back in Patiala she faced a large Maratha force marching towards the town in 1794 under the command of Anta Rao and Lachhman Rao.Raja Bhag Singh of Jind,Jodh Singh of Kalsia and Bhanga Singh of Thanesar joined hands n with her while Tara Singh Ghaiba sent a detachment of troops. The joint force, numbering about 7,000 men, met the enemy at Mardanpur near Ambala where a fierce engagement took place. The Sikhs were severely outnumbered and would have retreated had not Sahib Kaur, alighting from her rath, i.e. chariots made a brave call with a drawn sword in hand for them to stay firm in their ranks. The next morning they made a sudden charge on the Marathas who, taken by surprise, retired towards Karnal in utter confusion.
