In August 1940 the decision was made to group the Royal Marine Brigades under a full Royal Marine Division. A key element of this plan was the raising of a third brigade, the 103rd RM Brigade consisting of the 7th & 8th RM Battalions (the 6th RM Battalion having been permanently disbanded as a mark of disgrace following the mutiny in Murmansk in 1919). However, the deteriorating situation in the Eastern Mediterranean resulted in the 103rd RM Brigade functioning as a holding unit for recruits for the RM Mobile Naval Base Defence Organisation in Alexandria, with both the 7th & 8th RM Battalions eventually being transferred to that Theatre.
