6 Group was a Royal Canadian Air Force formation, differing from the previous No.

Air Commodore Charles Rumney Samson led No.

6 Group RCAF was made up of Article XV squadrons: RCAF units formed under the British Commonwealth Air Training Plan, for service with British operational formations; hence No.

6 Group was part of Royal Air Force (RAF) Bomber Command.

Significant operations involving 6 Group included raids on U-boat bases in Lorient and Saint-Nazaire, France and night bombing raids on industrial complexes and urban centres in Germany.

To this end, 6 (RCAF) Group was formed on 25 October 1942[4] with eight squadrons.

[5][6] Headquarters for 6 Group was at Allerton Park near Knaresborough and Harrogate in North Yorkshire.

[11] Like most other groups within RAF Bomber Command, the "base" system was used for station organization.

A base consisted of a main station, or headquarters, and a number of sub-stations.

Late in 1943, Bomber Command bases were designated with a two-number identifier.
