The verified answer to “Important Battles question: The Battle of Koregaon (1818) - the Mahar soldiers fought for the British against the Peshwa. The source-backed, question-specific record explains: The Battle of Bhima Koregaon (January 1 1818) saw the British forces commanded by Captain Francis Staunton. He led approximately 500 soldiers (mainly from the Mahar community) against the Peshwa Bajirao II's much larger force. This evidence establishes the historical relationship required in this Important Battles item. A correct solution must preserve the exact battle, date, participants, commander, location, outcome or significance requested by the stem. Similar periods, genres or national traditions do not make two battle facts interchangeable. Option A gives Captain Staunton and satisfies every condition stated in the question. The remaining choices—Major Munro, Sir Arthur Wellesley and Colonel Outram—do not satisfy the complete requirement. Depending on the stem, a distractor may name a real commander but attach the wrong title, use a related event involving another power, reverse a correct association, or present a correct statement when the question specifically asks for the incorrect match. The reliable checking method is to identify the named battle first, recall or verify its verified participant or outcome, and then read qualifiers such as “both works,” “original language,” “first published,” “correctly matched” or “incorrectly matched.” These qualifiers determine what counts as the answer. Replaying that method for this Important Battles question confirms Captain Staunton without relying on option position. This approach builds accurate historical knowledge and careful option elimination for SSC, Railway, Banking, Defence, State and other competitive examinations.
