"England expects that every man will do his duty", here represented with Popham's "Telegraphic Signals of Marine Vocabulary", was a signal sent by Royal Navy Vice Admiral Horatio Nelson, 1st Viscount Nelson from his flagship HMS Victory as the Battle of Trafalgar was about to commence on 21 October 1805. The English victory over Napoleon's forces in the battle removed all possibility of a French invasion and conquest of Britain.Drawing: Ipankonin
