While crossing the Kaitna River in 1803, Arthur Wellesley was early killed when an enemy artillery barrage decimated his column, and a cannonball decapitated his orderly, who was riding just behind Wellesly at mid-channel.
So what if Wellesley, instead of his orderly, was killed by the cannonball, and the British lose the Battle of Assaye, where they were outnumbered six to one? What effect does this have on the British in India, and in the Napoleonic Wars in general?
