Battle of Assaye

The Battle of Assaye was a major battle of the Second Anglo-Maratha War fought between the Maratha Confederacy and the British East India Company. It occurred on 23 September 1803 near Assaye in western India where an outnumbered Indian and British force under the command of Major General Arthur Wellesley (who later became the Duke of Wellington) defeated a combined Confederacy army of Daulat Scindia and the Raja of Berar. The battle was the Duke of Wellington's first major victory and one he later described as his finest accomplishment on the battlefield.

From August 1803, Wellesley's army and a separate force under the command of his subordinate Colonel James Stevenson 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 Europeanised infantry and artillery as the British forces closed in on his position.

Wellesley received intelligence indicating the location of the Maratha encampment on 21 September and devised a plan whereby his two armies would converge on the Maratha position three days later. 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. A combination of bayonet and cavalry charges eventually forced the Maratha army to retreat with the loss of most of their guns, but Wellesley's army was too battered and exhausted to pursue.

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.
