In January 1931, Glorious and Eagle took part in what is identified here as the first official carrier-versus-carrier battle-group exercise. Rear Admiral Reginald Henderson oversaw the event after earlier experience commanding a carrier. The exercise shows that the Royal Navy was testing carrier combat against an opposing carrier force a decade before the Pacific War. It complements construction totals with evidence of doctrinal experimentation and ownership of new hulls.
