The Battle off Mukah was a naval engagement fought in May 1862 between boats of the Sarawak and pirates.[1] After the kidnapping of Sarawakian citizens some time before, two small gunboats encountered the pirates off Mukah on the northern coast of Borneo. In an unusual action, the Rajah Muda, Captain John Brooke, then the heir apparent to be White Rajah of Sarawak, led his force in the defeat of six pirate ships and the rescue of captured civilians.[2]
