The correct answer is Narnaul.

• Narnaul was the region in which Colonel Gerrard led the counter-attack against 1857 revolutionaries.

• The British authorities at Delhi were alarmed by these developments. They sent a strong column comprising about 1,500 strong under Colonel Gerrard, an officer of conspicuous merit on November 10, 1857.
• After a few days' rest at Rewari (Rampura), Col. Gerrard proceeded to Narnaul via Kanaud and reached there in the evening. In the night he was joined by the Haryana Field Force.
• On November 16, Gerrard marched to Narnaul.
  • As the track was sandy, the column reached Nasibpur, small village, 3 km north-west of Narnaul and halted for a short rest.
  • The rebel force, having abandoned their strong fort in the centre of the town pounced on them.
  • Rao Tula Ram's first charge was irresistible and the British forces scattered before them.
  • The Patiala Infantry and the Multani Horse on the British side were completely disheartened.
  • The whole of the right flank fled. But at this juncture, the Guides and the Carabineers came to their rescue and saved the situation.
