Battle of Poona

The Battle of Poona took place on 25 October 1802 near Pune between the rival factions of the Maratha Confederacy. The forces of the Scindia (Shinde) and the Peshwa Bajirao II were attacked by the Holkars. While the British East India Company was not involved in the battle, its outcome and aftermath led to the Second Anglo-Maratha War.

In May 1802, Maharaja Yashwantrao Holkar marched towards Pune to solve the disputes. He conquered Sendhwa, Chalisgaon, Dhulia, Malegaon, Parol, Ner, Ahmednagar, Rahuri, Nashik, Sinnar, Dungargaon, Jamgaon, Pharabagh, Gardond, Pandharpur, Kurkumb, Narayangaon, Baramati, Purandhar, Saswad, Moreshwar, Thalner, and Jejuri.

On Sunday, 25 October 1802, on the festival of Diwali, Yashwantrao Holkar defeated the combined armies of Scindia and Peshwa at Hadapsar, near Pune. The battle took place at Ghorpadi, Banwadi and Hadapsar. Maharaja Yashwantrao Holkar is said to have ordered his army not to attack first and wait until 25 cannonballs were fired from other side; when the 25 cannonballs were fired, Maharaja Yashwantrao Holkar ordered his army to attack. As soon as he won the war, he ordered his army not to harm the civilians of Pune.

The Peshwa, when he learned that he was defeated, fled from Pune via Parvati, Wadgaon to Sinhagad. Maharaja Yashwantrao Holkar asked the Peshwa to return to Pune.

On 27 October 1802, Peshwa Bajirao (II), along with Chimnaji, Baloji, and Kunjir along with some soldiers of Scindia, went to Raigad and spent one month in Virwadi. He then went to Suwarnadurgh, and on 01/12/1802, went to Bassein via a ship named Harkuyan. The British offered him enticements to sign the Subsidiary Treaty in return for the throne. After deliberating for over a month, and after threats that his brother would otherwise be recognised as Peshwa, Bajirao (II) signed the treaty, surrendering his residual sovereignty and allowing the English to put him on the throne at Poona. This Treaty of Bassein was signed on 31 December 1802.
