Orange Lilies (The).
The 35th Foot. Called orange because their facings
were orange till 1832; and lilies because they were given white plumes in recognition of their gallantry in the battle of Quebec in 1759, when they routed the Royal Roussillon French Grenadiers. The white plume was discontinued in 1800. The 35th Foot is now called the The Royal Sussex.
