The Third Anglo-Maratha War (1817–1818)—often remembered alongside the Pindari War—was the final, decisive military contest for the destiny of the Indian subcontinent. While previous conflicts chipped away at regional borders, this campaign obliterated the Maratha Empire, dissolved the centuries-old Peshwaship, and transformed the British East India Company (EIC) from a dominant regional power into the unchallenged imperial sovereign of India.
Origins and Causes: The Unraveling Peace
The uneasy peace established after the Second Anglo-Maratha War (1803–1805) left the Maratha princes politically emasculated, financially drained, and bitterly resentful of British intervention.
1. The Pindari Menace
The demobilization of massive Maratha armies after 1805 left tens of thousands of armed cavalrymen without employment. These irregular horsemen coalesced into ruthless raiding confederations known as the Pindaris. Operating out of central India under leaders such as Karim Khan, Chitu Khan, and Wasil Muhammad, they launched devastating, fast-moving plundering raids across central and southern India, eventually striking deep into British-administered territories in the Northern Circars and Madras Presidency.
While the British viewed the Pindaris as lawless marauders requiring total eradication, many Maratha rulers—notably Daulat Rao Scindia and Malhar Rao Holkar II—tacitly harbored and protected them, viewing them as valuable irregular auxiliaries in any future confrontation with the British.
2. Chafing Under the Subsidiary Alliance
British Residents stationed at Maratha courts (such as Mountstuart Elphinstone at Poona and Richard Jenkins at Nagpur) ceased acting as diplomats and functioned as de facto colonial overseers. Peshwa Baji Rao II despised the indignities of the Treaty of Bassein. Stripped of foreign policy autonomy and surrounded by Company regiments, he began covertly rallying the Maratha houses—Gwalior, Indore, and Nagpur—to present a united front against British hegemony.
3. The Murder of Gangadhar Shastri (1815)
Tensions reached a boiling point in 1815 when Gangadhar Shastri, an envoy sent by the Gaekwad of Baroda to negotiate financial settlements with the Peshwa under British safe-conduct, was assassinated at Pandharpur. The British implicated Trimbakji Dengle, a fiercely anti-British minister and confidant of Baji Rao II. Elphinstone forced the Peshwa to arrest Trimbakji, but his subsequent dramatic escape convinced the British that the Peshwa was actively organizing open rebellion.
4. The Humiliating Treaty of Poona (June 1817)
Mountstuart Elphinstone confronted Baji Rao II with an ultimatum. Backed by Company bayonets, the Peshwa was coerced into signing the Treaty of Poona on June 13, 1817:
- He officially renounced his position as the head of the Maratha Confederacy.
- He severed all political and diplomatic connections with foreign powers and constituent Maratha chiefs.
- He ceded significant territorial revenues in the Deccan and Gujarat to support British troops.
The treaty extinguished whatever semblance of prestige the Peshwa retained. Baji Rao II resolved to risk everything on war.
The Participants: Key Figures and Armies
| Faction | Leadership & Commanders | Military Profile |
|---|---|---|
| British East India Company | • Francis Rawdon-Hastings(Marquess of Hastings, Governor-General & Commander-in-Chief) • Sir Thomas Hislop (Army of the Deccan) • Mountstuart Elphinstone(Resident at Poona) • Brigadier-Generals Lionel Smith, John Malcolm, and Thomas Munro | The largest force assembled by the British in India up to that point: ~120,000 troops, 300 modern artillery pieces, rigid discipline, unified command, and superior military logistics. |
| Maratha Coalition | • Peshwa Baji Rao II & General Bapu Gokhale (Poona) • Mudhoji II Bhonsle (“Appa Sahib”) (Nagpur) • Malhar Rao Holkar II & Tatya Jog (Indore) • (Daulat Rao Scindia forced into neutrality) | Exceptional light cavalry, courageous frontline charges, but crippled by poor coordination, internal court treachery, and a lack of modern tactical cohesion. |
The Outbreak and Course of the War
Lord Hastings assembled two massive forces: the Grand Army of the North (~40,000 men under Hastings) and the Army of the Deccan (~70,400 men under Sir Thomas Hislop). Ostensibly mobilized to encircle and annihilate the Pindaris, this grand pincer movement was designed to instantly crush any Maratha ruler who dared intervene.

1. Scindia Neutralized: The Treaty of Gwalior (November 1817)
Before the campaign commenced in the Deccan, Hastings surrounded Daulat Rao Scindia’s territories with the Northern Army. Intimidated by the overwhelming force, Scindia signed the Treaty of Gwalior on November 5, 1817, surrendering all authority to move his armies and agreeing to cooperate in eradicating the Pindaris. The most powerful Maratha army was sidelined without firing a shot.
2. The Peshwa’s Uprising (November 1817 – June 1818)
On November 5, 1817, Baji Rao II’s troops sacked and burned the British Residency at Poona.
- Battle of Khadki (Kirkee, Nov 5, 1817): A Maratha force led by Bapu Gokhale attacked British lines at Khadki but was repelled by disciplined European and sepoy fire. Elphinstone quickly occupied Poona, forcing the Peshwa to become a fugitive.
- Battle of Koregaon (January 1, 1818): A tiny detachment of 800 Company troops (predominantly Mahar sepoys from the Bombay Native Infantry) under Captain Francis Staunton defended the village of Koregaon against an overwhelming vanguard of the Peshwa’s army, successfully denying them passage across the Bhima River.
- Battle of Ashti (February 1818): General Lionel Smith intercepted the retreating Marathas. General Bapu Gokhale, the last great commander of the Peshwa, was killed while leading a rearguard cavalry charge. Baji Rao II fled continuously until his surrender to Sir John Malcolm in June 1818.
3. The Collapse of Nagpur
Upon hearing of the Peshwa’s uprising, Appa Sahib of Nagpur openly declared for Baji Rao II.
- Battle of Sitabuldi (November 26–27, 1817): A small British and Madras Sepoy garrison entrenched on Sitabuldi Hill held off massive assaults by Nagpur’s Arab mercenaries and regular troops.
- Appa Sahib surrendered, but continued fomenting rebellion until he was deposed, fleeing to Jodhpur where he died in exile.
4. Holkar’s Defeat at Mahidpur (December 21, 1817)
The court of Indore, dominated by war factions and young Malhar Rao Holkar II, mobilized to join the Peshwa. Sir Thomas Hislop confronted them on the banks of the Kshipra River at the Battle of Mahidpur. Despite ferocious resistance from Holkar’s batteries, the British infantry overran the guns. Holkar was decisively defeated, bringing Indore to terms.
5. Annihilation of the Pindaris
Simultaneously, British hunting columns systematically tracked down the Pindaris across the dense forests and hills of Malwa. Deprived of shelter by Scindia and Holkar, the bands disintegrated:
- Karim Khan surrendered and was settled as a minor landowner in Gorakhpur.
- Wasil Muhammad was captured and committed suicide in EIC custody.
- Chitu Khan, hunted relentlessly through the jungle, was ultimately mauled and killed by a tiger in the forests of Asirgarh.
Treaties and Territorial Reorganization
The aftermath brought sweeping diplomatic and political restructuring:
- Treaty of Mandasor (January 6, 1818): Signed with Holkar. Indore ceded all territories south of the Satpura Range (Khandesh), relinquished claims over Rajput states, drastically slashed its army, and accepted a permanent subsidiary force and British Resident.
- Abolition of the Peshwaship: Lord Hastings enacted a historic, non-negotiable decree: the title and political office of Peshwa were formally abolished. Baji Rao II was stripped of his realm, granted an annual pension of £80,000 (800,000 rupees), and banished to Bithoor (near Kanpur) in northern India, far from his ancestral power base in Maharashtra.
- Creation of the Satara Puppet State: To placate traditional Maratha sentiment, Hastings resurrected a nominal Maratha kingdom. He placed Pratap Singh, a direct descendant of Chhatrapati Shivaji Maharaj, on a puppet throne at Satara under tight British tutelage.
- Annexation of the Bombay Presidency: The vast territories previously ruled directly by the Peshwa were annexed to create the expanded Bombay Presidency, organized administratively by Mountstuart Elphinstone.
Why the Third Anglo-Maratha War Gave the British Entire India
Historians consider this war the definitive moment the British conquered India for several key reasons:
1. The Removal of the Only Pan-Indian Rival
The Maratha Confederacy was the only indigenous imperial project with the geographic reach, administrative network, and military strength capable of displacing the Mughal Empire and resisting European colonization on a continental scale. Once the Maratha houses were dismantled, there was no rival power capable of mounting an all-India resistance.
2. The Total Vassalage of Rajputana and Central India
With Scindia, Holkar, and the Peshwa broken, the Rajput states (such as Jaipur, Jodhpur, Mewar, and Kota), which had spent decades paying tributes (chauth) to Maratha chieftains, rushed into treaties of paramountcy and protection with the British in 1818. Central India and Rajputana transformed overnight into an unbroken zone of British client principalities.
3. A Single Imperial Master
Before 1817, the British ruled disjointed coastal enclaves, the Bengal plains, and parts of the south. After 1818, the EIC held direct or indirect administrative dominion from the Himalayas to Cape Comorin, and from the Indus basin to the Bay of Bengal. The remaining independent powers on the periphery—the Sikh Empire of Ranjit Singh in the Punjab, the Amirs of Sindh, and the Kingdom of Burma—were frontier kingdoms, not contenders for the throne of Hindustan.
Historical Impact and Legacy
On the Marathas
The proud military-administrative framework built by Shivaji Maharaj and expanded by the early Peshwas was extinguished. The confederacy’s warrior classes were largely disarmed, their fortresses dismantled, and their lands placed under British revenue systems like the Ryotwari and Inam commissions. Decades later, the smoldering resentment over the abolished Peshwaship would re-emerge dramatically when Baji Rao II’s adopted son, Nana Saheb, led the uprising at Kanpur during the Revolt of 1857.
On the British
The British East India Company ceased behaving as an armed mercantile corporation; it became an undisputed colonial state. Lord Hastings completed what Lord Wellesley had started, shifting British policy from isolation and balance of power to undisputed paramountcy. The profits, revenue apparatus, and massive sepoy armies created during the Maratha wars gave Britain the springboard to launch the First Anglo-Burmese War (1824) and the First Anglo-Afghan War (1839).
On India
The war integrated the disparate regions of the subcontinent into a centralized political framework under a single foreign power. While it ended decades of chaotic warfare and lawlessness caused by roving armed bands in central India, it ushered in an era of direct colonial exploitation, de-industrialization, and political subjugation that would endure until 1947.
