Buxar, or Baxar, a town of India, in the district of Shahabad, Bengal, on the south bank of the Ganges, and on the East Indian railway. Pop. (1901) 13,945. There is a dismantled fort of small size which was important from its commanding the Ganges. A celebrated victory was gained here on the 23rd of October 1764 by the British forces under Major (afterwards Sir Hector) Munro, over the united armies of Shuja-ud-Dowlah and Kasim Ali Khan. The action raged from 9 o'clock till noon, when the enemy gave way. Pursuit was, however, frustrated by Shuja-ud-Dowlah sacrificing a part of his army to the safety of the remainder. A bridge of boats had been constructed over a stream about 2 m. distant from the field of battle, and this the enemy destroyed before their rear had passed over. Through this act 2000 troops were drowned, or otherwise lost; but destructive as was this proceeding, it was, said Major Munro, "the best piece of generalship Shuja-ud-Dowlah showed that day, because if I had crossed the rivulet with the army, I should either have taken or drowned his whole army in the Karamnasa, and come up with his treasure and jewels, and Kasim Ali Khan's jewels, which I was informed amounted to between two and three millions."
