An Order-in-Council dated 18th August 1804 authorised the formation of artillery companies as part of the Royal Marine Forces "under the denomination of' Royal Marine Artillery"'. The Corps was granted the title 'Light Infantry' in 1855 and for a short period the title was 'Royal Marines, Light Infantry'. The buttons of the RMA always read 'ROYAL MARINE ARTILLERY'. However, in the Light Infantry, the buttons and officers' Undress white belt locket (worn until 1905) always read 'ROYAL MARINES LIGHT INFANTRY', right up until 1923 when, as will be noted in Part 2, the Corps was amalgamated and the 'ROYAL MARINES' button was introduced.
