On 8 September 1857, the Legion defeated a force of local levies raised by the Raja of Jodhpur, who remained loyal to the British.

Subsequently, this Legion remained at Auwa till 10 October 1857, when they embarked on a march towards Delhi via Marwar Junction and Rewari.

The British sent a force commanded by Colonel John Grant Gerrard from Delhi to intercept them.

On 16 November 1857, a battle took place at Narnaul where Gerrard's force defeated the Legion.
