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 13 June 1940, Lieutenant-General Sir Alan Brooke assumed command of all British troops still in France. He placed the British units fighting with the Tenth Army (France) under the command of Lieutenant-General J. H. Marshall-Cornwall. This improvised formation was known as Norman Force and comprised (on 15 June): 3rd Armoured Brigade, 157th Infantry Brigade, 71st Field Regiment R.A., and Troop Carrying Company, 52nd Division.
