He is recorded as having been with D Company, 7th Battalion, Royal Sussex Regiment in 1940. He appears in a photograph of Officers taken in March 1940. It is thought he deployed to France with the Battalion, but it is unclear if he was with them when they were effectively destroyed at Amiens on 20th May 1940, holding up German Panzer units without support. Some survivors did manage to escape back to England, to join a reformed unit. This was disbanded in December 1941, though most of the men had been transferred in April to an anti-aircraft unit.

Major RFH Darwall-Smith was also a Royal Sussex Regiment Officer with a seniority just 8 places ahead of Holberton. He is likely to have known him well and may have been responsible for Holberton's recruitment to Auxiliary Units.
