[3][a] Towards the close of 1808, Rear-Admiral Drury wished to threaten Canton in order to press some demands on the Chinese government.

He dispatched Kempthorne in command of a small squadron consisting of Diana, a prize brig, and the British East India Company's vessel Discovery.

[3] Diana and Discovery then sailed to Manila in January 1809 to recover Captain William Pakenham and the crew of the frigate HMS Greyhound which had been wrecked in the Philippines on 4 October 1808.

Diana escaped by throwing her guns overboard and sailing by Point Romania (near Pedra Branca, Singapore), however the French captured Discovery, which was carrying Captain Packenham and some of his officers and crew.

[b] On 10 September 1809 Diana was sailing into the Bay of Amarang (Amurang) in the north-east corner of the island of Celebes when she sighted the Dutch 14-gun brig Zephyr anchored under a fort.
