British Tars, towing the Danish fleet into harbour
"The Broad-bottom Leviathan trying to swamp Billy’s old-Boat, & the little Corsican tottering on the Clouds of Ambition" – three sailors rowing a small ship’s boat or dinghy, (the Billy Pitt) are going through rough water caused by Leviathan, a porpoise-like monster with three heads and a forked tail. The heads spout water at the boat, particularly at Canning. They are (r. to left.) Grenville, who spouts "Opposition Clamour"; Howick (whom Canning had replaced as Foreign Secretary), spouting "Detraction"; and St. Vincent, spouting "Envy".
