Meanwhile the party of the first battalion at the Isle of Roderigue had sailed from thence with the forces under Lieut.-Colonel Keating, to co-operate with the British navy in blockading the Isles of France and Bourbon, and in attacking the enemy’s ports. At five o’clock on the morning of the 21st of September, six hundred men landed in three columns, seven miles from the port of _St. Paul’s_, in the Isle of Bourbon, then called by the French the Isle of Bonaparte, and by a forced march crossed a causeway extending over the lake, before the enemy discovered their disembarkation or approach to the town; they also passed the enemy’s strongest position by seven o’clock, and gained possession of two batteries before the enemy could form in force. Captain Imlack, of the Bombay Native Infantry, was detached with one hundred and fifty men to take possession of a third battery; and on his way he encountered the French forces, concentrated behind a stone wall, with eight field-pieces on their flanks. This post was instantly attacked in a most gallant manner; Captain Hanna of the FIFTY-SIXTH Regiment arrived with the third column, and charging, captured two guns; and Captain Forbes, of the FIFTY-SIXTH Regiment, advancing with the reserve, the enemy was compelled to retreat with the loss of his artillery. A few men were detached in pursuit; two additional batteries were captured, and by half-past eight o’clock the town, batteries, magazines, eight brass field-pieces, and one hundred and seventeen new iron guns, were in possession of the British troops: at the same time the enemy’s shipping were forced to surrender to the British naval force. Thus was accomplished a most brilliant exploit, in a few hours, and it reflected great credit on the commanding officer, Lieut.-Colonel KEATING, of the FIFTY-SIXTH, and on all the troops engaged. The loss of the regiment was one serjeant, and five rank and file killed; one serjeant and twenty-six rank and file wounded. The town being commanded by the British naval force, the troops returned on board the fleet; part of the enemy’s stores and the guns were destroyed; the remainder were embarked on board the company’s recaptured ship Streatham, which, with the Europe, were placed under their former commanders. In October the troops sailed for the Isle of Roderigue. The conduct of Ensign Pearce, of the FIFTY-SIXTH Regiment, was highly commended in the public despatch of Lieut.-Colonel Keating.
