No. 8 Group RAF-- Part 1: In Both World Wars

From Wikipedia.

The No. 8 Group RAF (Royal Air Force) existed in the final year of the First World War and during the Second World War.

During the First World War it was formed in April 1918 as a training unit and designated  as 8 Group (Training).  It remained  at this for the remainder of the war and was disbanded May 1919.

SECOND WORLD WAR

The group was re-established as No. 8 (Bomber) Group on 1 September 1941 only to be disbanded  around five months later on 28 January 1942.

However, 8 Group was re-constituted when Bomber  Command's Pathfinder Force was redesignated No. 8 (Pathfinder Force) Group on 8 January 1943.
