The Battle of Delhi took place on 11 September 1803 during the Second Anglo-Maratha War, between British troops under General Lake, and Marathas of Scindia's army under French General Louis Bourquin. The battle was fought at Patparganj, right across Yamuna River from Humayun's Tomb, also giving the battle its local name.

The Marathas occupied a strong position with the Jumna in their rear, and Lake, feigning a retreat, drew them from their lines, and then turning upon them drove them with the bayonet into the river, inflicting more losses upon them. The city of Delhi surrendered three days later.

A monument was later erected at the site in Patparganj, marked out by a surrounding ditch, commemorating Cornet Sanguine and British soldiers who fell during the battle.

Delhi (/ˈdɛli/; locally pronounced Dillee or Dehli), officially the National Capital Territory of Delhi (NCT), is the largest metropolis by area and the second-largest metropolis by population in India. It is the eighth largest metropolis in the world by population with 16.7 million inhabitants in the Territory at the 2011 Census. The region has been given special status of National Capital Region under The Constitution (69th Amendment) Act, 1991. There are nearly 22.2 million residents in the greater National Capital Region urban area (which also includes the cities Noida, Greater Noida, Ghaziabad, Gurgaon,Sonepat and Faridabad along with other smaller nearby towns).

Delhi is known to have been continuously inhabited since at least the 6th century BCE, though human habitation is believed to have existed since the second millennium BCE. Delhi is also widely believed to have been the site of Indraprastha, the legendary capital of the Pandavas during the times of the Mahabharata. Delhi re-emerged as a major political, cultural and commercial city along the trade routes between northwest India and the Gangetic plain after the rise of the Delhi sultanates. It is the site of many ancient and medieval monuments, archaeological sites and remains.
