A naval officer from Dundee, Duncan's career had been worthy but unremarkable until his last posting, when he emerged as one of Britain's great heroes of the Napoleonic Wars. With Duncan at its command, a North Sea fleet achieved a resounding victory over the Dutch at the Battle of Camperdown on 11 October 1797. Danloux, painting two years after the event, imagines Duncan, calm in the midst of gun and cannon fire, on the deck of the Venerable. The officer blowing a trumpet symbolises Fame.
