The Battle of Laswari took place on 1 November 1803 near Laswari village, Alwar.[2] It was part of the Second Anglo-Maratha War.
The British under Gerard Lake were anxious to finish the war by neutralizing the last substantial force that the Maratha confederacy possessed, consisting of twelve battalions of regular infantry trained by the adventurer Chevalier Dudrenec. Dudrenec deserted the Marathas and command fell onto Ambaji Ingle, a veteran Maratha officer.
Lake decided to dispense first with his artillery and later with his infantry in a series of forced marches to catch up with the Maratha force. Lake initially encountered the enemy force with just three brigades of cavalry, but the British troopers by repeated charges were able to contain the Maratha Army until the British infantry arrived.
The British units, commanded by Lake, were about 10,000 men strong, opposing Sindhia's force of 9,000 veteran infantry and 5,000 cavalry under the command of Ambaji Ingle. The British units were also supported by additional allied troops from Alwar.
The Maratha infantry made a most gallant defence, standing their ground until the survivors laid down their arms. The cavalry also suffered heavily. The British captured 72 guns and a large quantity of ammunition and stores. Lake later wrote, "I never was in so severe a business in my life or anything like it… these fellows fought like devils, or rather like heroes".[3]
"The casualties on both sides were very heavy. The Company lost many officers, including Maj. Gen. Weir, Col. Vandeleur and Maj. Griffith. Lake's son was also killed."[4]
On 17 December 1803, Raghuji Bhonsale (II) of Nagpur signed the Treaty of Deogaon with the British after the Battle of Laswari and gave up the province of Cuttack including Balasore.
In this battle, the people of the Meena tribe of Shahjahanpur fought a lot and drove the British away.
