In 1801, 'Sir' Levett Hanson wrote to Admiral Lord Horatio Nelson offering him membership of the order to recognize his victory at the Battle of the Nile. Following the review and approval of the English College of Arms, the King's Warrant approving the acceptance and wear of the insignia of the Order of Saint Joachim was granted. Nelson was wearing the breast cross of the Order of Saint Joachim at the Battle of Trafalgar and is still seen on the famous "Trafalgar coat" in the National Maritime Museum in Greenwich, UK. Several other Englishmen later received the King's Warrant to accept the Order of Saint Joachim, including Nelson's brother, Viscount Merton, General Sir Charles Imhoff, and Philippe d'Auvergne, Prince de Boullion, Rear Admiral of the Blue. In 1802, Hanson published "An Accurate Historical Account of all the Orders of Knighthood at present existing in Europe" casting the Order of Saint Joachim as equal to existing chivalric orders and dedicating the work to Nelson.
