Wellesley's force, however, encountered the Maratha army – which was under the command of Colonel Anthony Pohlmann, a German formerly in British service – 6 miles (9.7 km) farther south than he anticipated. Although outnumbered, Wellesley resolved to attack at once, believing that the Maratha army would soon move off. Both sides suffered heavily in the ensuing battle; Maratha artillery caused large numbers of casualties among Wellesley's troops but the vast numbers of Maratha cavalry proved largely ineffective.
