In the late summer-early autumn, "Hound" took part in the Helder expedition, a joint Anglo-Russian invasion of Holland under the command of Vice-Admiral Andrew Mitchell. At the Neiuw Diep the British captured seven warships and 13 Indiamen and transports. Mitchell then obtained the surrender of a squadron of the navy of the Batavian Republic in the Vlieter Incident. The Dutch surrendered twelve vessels ranging in size from the 74-gun "Washington" down to the 16-gun brig "Galathea".
