Final answer:
The Nawab and Hindu Diwaan responsible for leading the Mughal attack on the Sikhs in the Chhota Ghalughaara were Nawab Yahiya Khan and Hindu Diwaan Lakhpat Rai.
Step-by-step explanation:
In the event known as the Chhota Ghalughaara, the Mughal attack on the Sikhs at the Raavi River was led by Nawab Yahiya Khan and Hindu Diwaan Lakhpat Rai. This tragic event is a significant part of Sikh history and showcases the persecution faced by Sikhs during the period of Mughal rule in India, specifically under the reign of Aurangzeb, who was known for his oppression of the Sikh community. In the Chhota Ghalughaara incident, the Nawab and Hindu Diwaan who led the sudden Mughal attack on the Sikhs as they crossed the Raavi River were Yahiya Khan and Lakhpat Rai. The Chhota Ghalughaara is remembered as a smaller massacre compared to the larger one that happened later, but it was still a brutal attack that caused immense loss to the Sikhs.
