These splendid successes, connected with the services of the royal navy, had produced important results; the maritime provinces of Mergui, Tavoy, Yeb, and Martuban, had been captured, and seven hundred pieces of artillery had been taken from the Burmese. To wrest additional territory from the court of Ava, the THIRTEENTH regiment was detached, under Major Dennie, with other troops, the whole under Major Sale, against the city of _Bassein_, in the south-west part of the ancient kingdom of Pegu, which constituted part of the Burmese empire. The regiment embarked on this service on the 10th of February, and after a tedious passage arrived, on the evening of the 14th, off Pagoda Point, Great Negrais. On the 26th the expedition entered the river, and the THIRTEENTH, thirty-eighth, and twelfth Native Infantry landed and captured a stockade. The troops afterwards re-embarked, and proceeded to the next stockade, which the Burmese abandoned as the soldiers went on shore to storm the works; and so great was the consternation of the enemy, that the city of Bassein was set on fire and abandoned. The expedition anchored opposite the smoking ruins on the 3rd of March, when the troops landed and took post in the area of the principal pagoda: many private houses were not destroyed, and the inhabitants were induced to return to their homes. On the 13th of March, Major Dennie made a reconnoissance up the Bassein river; he was afterwards joined by another party under Major Sale, and the whole proceeded one hundred and twenty miles up the river, to Lanrince, and returned to Bassein on the 23rd, having had two men wounded. No resistance being met with in the province of Bassein, the THIRTEENTH regiment embarked for Rangoon, where it arrived on the 2nd of May; meanwhile the army under Lieut.-General Sir Archibald Campbell had advanced up the country, and had captured several strong towns. On the 8th of August, the regiment embarked from Rangoon, to join the army at Prome, where it arrived in boats on the 25th. Soon afterwards overtures of peace were made by the Burmese, but hostilities were resumed in the middle of November; and the army of Ava having repulsed the attack of three bodies of sepoys, became suddenly elevated with a high idea of its own power, and advanced to envelop the British troops at Prome. About sixty thousand Burmese environed six thousand British and native Indian troops; but undismayed by this formidable host, the English general left four native regiments for the defence of Prome, and advanced, on the 1st of December, to attack the enemy’s left wing at _Simbike_. This post was stormed by the troops under Brigadier-General Cotton,[17] and the works were carried, in gallant style, in ten minutes. The THIRTEENTH were engaged in the operation, but did not take part in the assault.
