In this first of a two-part sequence a respected vexillologist describes, explains and illustrates a wide variety of the standards and guidons carried during the 18th and 19th centuries by British Household, Regular, Yeomanry and Volunteer cavalry units. The successive regulations between 1747 and 1868 are supported by tables of 'ancient badges' and battle honours; by many examples of non-regulation practice (in the cavalier tradition of the British cavalry); and by ten dazzling plates by Richard Hook, detailing some 35 flags in full colour.
