The idea for the service came from Gilbert H. Carr during a meeting of The American Society in London shortly after the Dunkirk evacuation.
[2] The American Ambulance, Great Britain, operated from 17 stations across mainland Britain with five located in London and one each in Cardiff, Cambridge, Birmingham, Bristol, Edinburgh, Glasgow, Leeds, Manchester, Newcastle, Nottingham, Reading and Tunbridge Wells.
For most of the War, the headquarters were at 9 Grosvenor Gardens in London, formerly the offices of The Pyrene Company Limited.
[4] Members of the AAGB wore the tunic and skirt uniform as worn by those in the FANY but with crossed British and American flags on the sleeve.
During the course of the war, at least two members of the organisation were killed on active service: All the AAGB's vehicles were painted grey with a red strip and an emblem featuring the British and American flags.
