 The British immediately went on an offensive on all fronts.By April 1825, the British had driven out the Burmese forces from Arakan, Assam, Manipur, Tenasserim, and the Irrawaddy delta where Gen. Bandula died in action.After Bandula's death, the Burmese fought on but their last-ditch effort to retake the delta was repulsed in November 1825.
