We anchored, in the afternoon, off the mouth of the river Linga; and while there we dispatched a messenger to Seriff Jaffer to caution him against giving any countenance or support to either of the Seriffs Sahib and Muller, on whose punishment and destruction we were determined. The Batang Lupar, as far as this, is a magnificent river, from three to four miles wide, and, in most parts, from five to seven fathoms water. _Wednesday, 7th._--We weighed at daylight, but were obliged to anchor again before appearing in sight of Patusen, until the tide should rise sufficiently to enable us to pass a long flat shoal, over which, during the spring-tides, a bore rushes with frightful velocity. We now collected our boats, and made our arrangements as well as we could, for attacking a place we had not yet seen. We had now a little more difficulty in keeping our native force back, as many of those who had accompanied the expedition last year had gained so much confidence that the desire of plunder exceeded the feeling of fear. After weighing at 11, with a strong tide sweeping us up, we were not many minutes in coming in sight of the fortifications of Patusen; and indeed they were not to be despised. There were five of them, two not quite finished. Getting suddenly into six feet water, we anchored the steamer; not so formidable a berth, although well within musket-range, as we might have taken up had I been aware of the increasing depth of water nearer the town; but we approached so rapidly there was no time to wait the interpretation of the pilot's information. The Dido and Phlegethon's boats were not long in forming alongside. They were directed to pull in shore, and then attack the forts in succession; but my gallant first-lieutenant, Wade, who had the command, was the first to break the line, and pull directly in the face of the largest fort. His example was followed by the others; and dividing, each boat pulled for that which appeared to the officer in command to be the one most likely to make a good fight. The forts were the first to open fire on both steamer and boats, which was quickly and smartly returned. It is impossible to imagine a prettier sight than it was from the top of the Phlegethon's paddle-box. It was my intention to have fired on the enemy from the steamer, so as to draw their attention off the boats; but owing to the defective state of the detonating priming-tubes, the guns from the vessel did not go off, and the boats had all the glory to themselves. They never once checked in their advance; but the moment they touched the shore the crews rushed up, entering the forts at the embrasures, while the pirates fled by the rear.
