The advance was commenced on the 12th of February; owing to the nature of the country and the want of sufficient means for transporting the necessary military stores, part of the force proceeded by land, and the remainder in boats up the river Irawaddy. The flank companies of the ROYALS, commanded by Captain Tenison, formed the advance-guard of the land column, which was commanded by Brigadier-General Sir A. Campbell. Proceeding along a narrow and difficult path, tending obliquely toward the Irawaddy river, the column marched through the provinces of Lyng and Sarrawah; and on its arrival at Mophi, between two and three thousand Burmese, commanded by Maha Silwah, quitted an old pegaun fort, where they had evinced some determination to resist, and dispersed into a close jungle in the rear. From Mophi the column continued its progress, uninterrupted by the enemy, and forded the river Lyng at Thaboon on the 1st of March. The Carian inhabitants of the country through which the army marched viewed the expulsion of the Burmese with much satisfaction, and assisted the troops in making roads and in procuring supplies of rice and buffaloes. On the 2nd of March the division arrived at Sarrawah, on the Irawaddy, where its junction with the water column had been intended. This column had destroyed several of the enemy's stockades, and had continued its course up the river until it arrived within sight of _Donabew_, where a series of formidable stockades extending nearly a mile along the banks of the Irawaddy, and protected by about 15,000 Burmese, presented a formidable opposition. Information was received of a gallant but unsuccessful attack having been made on this post by the water column; and Sir Archibald Campbell resolved to retrace his steps with the land column, and concentrate his force for the reduction of this formidable position. He accordingly crossed the Irawaddy at Sarrawah by means of canoes and rafts, which, owing to the insufficiency of the craft employed, was not effected in less than five days. After halting two days at Henzada, the column pursued its march along the right bank of the river, and arrived before Donabew on the 25th of March: on the 27th a communication was opened with the water column, under Brigadier-General Cotton, of the 47th regiment, and both columns co-operated in the reduction of the place. Batteries were constructed without delay, and during the progress of these operations the enemy made several spirited _sorties_: on one occasion _seventeen elephants_ were sent out, each carrying a complement of men, supported by a body of infantry; but the result proved the inutility of employing such means against British troops. In the beginning of April the batteries opened their fire, and shortly afterwards, the Burmese commander, Maha Bandoola, having been killed by the bursting of a shell, the enemy deserted the place and retreated through the jungles in the direction of Lamina.
