It was reported that the Chinese were staking it across; and, from the bustle which had been previously observed there, when the boat of the Nemesis ventured into it, there was reason to believe that hostile preparations were being made. Moreover, it was thought advisable, if possible, to examine the channel which had been found to lead round in the rear of Anunghoy; for upon this fortress, as the most extensive of the defences of the Bogue, it was thought the principal attack of the squadron would be made. Suspicion was also excited by the contents of the intercepted despatch of Keshen to Admiral Kwan. On entering the river, it was no longer to be doubted that preparations for defence had been commenced. A great number of boats were observed busily employed in driving stakes or piles into the bed of the river, across which others were trying to moor a strong raft. No sooner was the steamer discovered approaching, than the boats all pulled away, and the Chinese were seen scampering off as fast as possible. However, when it came to the point of pulling up the stakes, in order to make a passage between them for the boats which were in tow, all on a sudden a heavy discharge from a masked battery, close abreast of the spot, was poured upon them, and at once betrayed the cause of the secret preparations before observed. The steamer immediately poured in a volley of grape and canister from her bow and stern guns, while the boats pulled away towards the shore, to carry the works by storm, opening their fire from their bow-guns as they advanced. The Chinese fled, after some resistance; and the battery, which was of very recent construction, was at once taken possession of by the crews of the boats, the colours being taken by Lieutenant Bowers. It was found to mount twenty guns of various calibre, which were immediately destroyed. There were also lying on the ground a vast number of guns dismounted, probably not less than sixty, which appeared to have been landed out of their junks, or recovered after the destruction of their fleet in the bay. These were all rendered useless, with the exception of a few brass ones, which were carried away as trophies. Their magazines and buildings were also totally destroyed. The number of killed among the Chinese were about thirty, but no wounded were found, as they had probably been carried off by their companions in arms. On our side no casualties happened.
