British Army (Early War)
Through the Early War (1939-1940) period, the ‘British Expeditionary Force’ (or ‘B.E.F.’ for short) fought to hold back the German advance up until the evacuation at Dunkirk.
Key Battles: Battle of Arras, Battle of Boulogne, Siege of Calais
Of course, these can all be used for the invasion of Britain as well!
