The Action of 26 July 1806 was a minor naval engagement of the Napoleonic Wars fought off the southern coast of the island of Celebes in the Dutch East Indies. During the battle, a small British squadron attacked and defeated a Dutch force defending a valuable convoy, which was also captured. The British force—consisting of the frigate HMS Greyhound and brig-sloop HMS Harrier under the command of Captain Edward Elphinstone—was initially wary of the Dutch, mistaking the Dutch East Indiaman merchant ship Victoria for a ship of the line. Closer observation revealed the identity of the Dutch vessels the following day and Elphinstone led his frigate against the leading Dutch warship Pallas while Harrier engaged the merchant vessels and forced them to surrender. Only the corvette William escaped, taking no part in the engagement.
