The Battle of Assaye was a major battle of the Second Anglo-Maratha War fought between the Maratha Empire and the British East India Company. It occurred on 23 September 1803 near Assaye in western India. The British Army was led by Major General Arthur Wellesley who later became the Duke of Wellington. The Maratha Army of Daulat Scindia and Raja of Berar was led by Anthony Pohlmann. From August 1803, Wellesley's army and a separate force under the command of his subordinate had been pursuing the Maratha cavalry-based army which threatened to raid south into Hyderabad. After several weeks of pursuit and countermarching, Scindia reinforced the combined Maratha army with his modernized infantry and artillery as the British forces closed in on his position. 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. Wellesley's victory at Assaye, preceded by the capture of Ahmednagar and followed by victories at Argaon and Gawilghur, resulted in the defeat of Scindia and Berar's armies in the Deccan. Wellesley's progress in the Deccan was matched by Lieutenant General Gerard Lake's successful campaigns in Northern India and led to the British becoming the dominant power in the heartlands of India.
