Final answer:
Banda Singh Bahadur led an attack on Samana to avenge Mughal persecution and establish Sikh dominance in the area, which was a milestone in the Sikh resistance against Mughal rule.
Step-by-step explanation:
Banda Singh Bahadur's army attacked Samana as a result of growing Sikh resentment against Mughal persecution, especially following the execution of Guru Gobind Singh's sons. Banda Singh Bahadur, inspired by Sikhism's founding principles and the injustice faced by his fellow Sikhs, led his forces against Samana to avenge the atrocities committed by the Mughals, which included religious suppression, and brutality against the Sikh population. The attack on Samana was a significant event leading to the establishment of Sikh dominance in the region and setting a precedent for Sikh resistance against Mughal rule.
