In the year 1846, several chiefs friendly to the English and opposed to piracy having been cruelly murdered by the Sultan of Brunei Sir Thomas Cochrane determined to destroy his city. There being sufficient water over the bar of the river, the Agincourt, towed by the Spiteful steamer, entered it and anchored within Moarra Island. The smaller vessels being lightened, proceeded up the river, carrying a force of 200 marines and 600 blue-jackets armed as light-infantry, accompanied by the boats of the squadron towed by the steamers. On turning an angle of the river four batteries were seen, two of which were directly ahead, while the stream was staked across. As the squadron was making its way through the piles, the enemy’s fire opened at a distance of 1000 yards. The round and grape passed between the masts of the Phlegethon and beyond theSpiteful, without striking. The guns having been pointed at the stakes, the Phlegethon immediately returned the compliment with rockets and her pivot-guns. After an hour’s cannonade, Captain Mundy shoved off in the gunboats, Lieutenant Patey being ordered to pull for the shore and to storm the batteries which were erected on a precipice nearly a hundred feet in height from the bank of the river. So heavy, however, had been the fire from the steamer and gunboats that the resolution of the enemy failed them, and the gallant crews forced their way through the embrasures. In capturing the enemy’s flag a skirmish took place between their rear-guard and the leading party of the British, while the former were endeavouring to escape into the jungle. Three handsome brass guns were carried off, the iron guns were spiked, and the magazines destroyed. The steamer then taking the Royalist and gunboats in tow, passed two other batteries and anchored half-a-mile below the city, when all hands went to dinner. At half-past one the expedition was again in motion, working up against an ebb tide of three knots. As the Phlegethon opened round the point, the city battery and hill forts mounting 18 guns, commenced firing, and two men were killed and several wounded on board thePhlegethon. She, however, opened a hot fire, and Captain Mundy shoving off in the gunboats, attacked the batteries at close quarters; but before he could reach them, the enemy fled. Nine shot had entered the Phlegethon’s side below the water-line; and had she not been divided into compartments, she would inevitably have sunk. The marines were now landed and occupied the heights above the sultan’s palace, the batteries on which had been silenced by the rocket and field-piece party under Lieutenant Paynter. The pirates had in the meantime manned the batteries already passed, on which Captain Mundy was sent down with the gunboats to destroy them. This he partially did in five hours, but so great was their strength that it would have taken days to do so effectually. Thirty-nine guns, mostly of large calibre, nineteen of them being of brass, fell into the hands of the British. The sultan and his boasted army had taken to flight. He was accordingly pursued by a party under Captain Mundy, to whom Lieutenant Vansittart acted as aide-de-camp. Having gone as far as they could in the boats, they landed, and in their progress destroyed several newly—erected forts. The natives now observing that no injury was done to private property, joined them and offered their services as guides. On their way they fell in with two houses belonging to the sultan, containing shields, arms, and magazines of powder. They were accordingly set on fire and destroyed, but the sultan himself escaped for the time, though his power was completely broken.
