In May, a fundamental change took place in the Indian army; the battalions were formed into regiments, and the officers of all branches of the service were placed on the same footing as to the chances of promotion, by the regiments being of equal strength in this particular. This new organization caused a considerable degree of promotion throughout the army, and in this the artillery shared. The officers of the regiment continued, as previously, to rise in one general gradation list, and the regiment was to be composed of

3 brigades of horse artillery,each consisting of 3 European and
 1 Native troop.
5 battalions of European foot artillery;each consisting of 4 companies.
1 battalion of Native foot artilleryeach consisting of20 companies.

The rocket-troop was to form one of the troops of a brigade.

Lascar details were attached to the troops, and a company to each European company, and a driver company to each field-battery.

These changes, however, were not even nominally carried into effect until the middle of the next year, owing to the scattered state of the regiment, the occupation the Burmese war gave, and the difficulty in obtaining a sufficient supply of European recruits to meet the demand. In reality, some of the troops of horse artillery were not formed until the end of 1826; we therefore shall not in this place give a tabular statement of the strength of the regiment, but reserve it until we arrive at the year 1826, when a reorganization of the native battalion made another change, and the state of the regiment, before and after its alteration, will then be seen at one glance.

The aggression of the Burmese on our frontiers, and the contempt with which they treated all remonstrances, forced the Indian Government reluctantly to declare war in 1824. Unfortunately, little was known of the country, and a most injudicious plan of operations was drawn out, which, by seizing Rangoon and the numerous native craft the maritime capital was expected to furnish, embarking the troops in them, and sailing up the Irawaddy in the rainy season, and threatening Amerapoora, was to terminate the war in one campaign. With this intention the expedition sailed in April, and was joined by the Madras portion early in May at Port Cornwallis in the Andaman Islands.

Two companies of the Bengal Artillery with their lascars accompanied the expedition.

On the 10th May the fleet reached Rangoon, and, overcoming a very faint resistance by a few broadsides from the Liffey, the troops landed and took possession. They found it deserted by its inhabitants, and incapable of affording either subsistence or the means of advancing. No choice was left; nothing could be done till the cold weather, except shelter themselves against the approaching rainy season, to which the Bengal monsoon is but as summer showers in comparison. During this season, the troops suffered much from exposure, from bad and insufficient supplies, harassment by the enemy, and continual petty attacks on stockades, so that when the season for operations arrived, it found an army of invalids, instead of one fit to take the field.

The Burmese recalled their army under Bundoola from Arracan, and it arrived in the vicinity of Rangoon in November. Rangoon was invested, but, awaiting reinforcements and supplies, Sir Archibald Campbell offered little opposition, contenting himself with strengthening his own position and placing all his artillery in battery, to bear on the enemy’s trenches. Things remained thus till the 5th December, when the guns all opening, the columns moved out under cover of their fire, attacked and overcame the enemy’s left; Bundoola, however, rallied again, and pushed on his attack on the Shevé-da-gon pagoda. On the morning of the 7th the attack was renewed; every gun that would bear on the enemy was opened, and continued firing till noon, when the infantry moving out, completely routed the enemy. He rallied in a strong position at Kokaing, from which, on the 13th, he was with difficulty dislodged, and in which action the regiment lost a fine young officer, Lieutenant O’Hanlon, who, volunteering with the body-guard, was shot in a gallant charge, made to cover a column hard pressed by the enemy.
