In the Battle of France in June 1940, Norman Force was a formation of units of the British Expeditionary Force, following the Dunkirk evacuation. On 12 June 1940, Lieutenant-General Sir Alan Brooke returned to France and next day, assumed command of all British troops still in France. He placed the British units fighting with the Tenth Army under the command of Lieutenant-General J. H. Marshall-Cornwall.
