The Battle of Sarai Nurdin was fought between the Khalsa's 2 Sikhs Bhai Bota and Bhai Garja Singh and the Mughal forces led by Subahdar (Governor) Zakariya Khan.

Zakariya Khan heard about this and immediately sent a Mughal force there under Jalal Din with 100-1000 Cavalry.

[7][1][2] Initially Jalal Din requested the Sikhs to surrender but they refused.

[9] Since fighting in horses wasn't working, the Mughals decided to retreat and send soldiers on foot.

Soon the Mughals realized that they can't fight the Sikhs in hand-to-hand combat so they finally brought in bullets.
