This is the updated edition of Saul David's first book, covering the actions of the 51st Highland Division in the France 1940 campaign.
The 51st Highland Division wasn't with the rest of the British Expeditionary Force when the German's launched their Blitzkrieg attack in May 1940. They were part of the Maginot Line forces and as such had to retreat around Paris towards the coast. This meant they were still part of the defence of France, indeed part of a French army corps, after the Dunkirk evacuation.
The Highland Division fought on the old WW1 battlefield of the Somme and then retreated over the River Bresle. The divisional commander, General Fortune, recognised that his Division was outnumbered and outgunned even with some limited armoured support from the under strength 1st Armoured Division. There was virtually no support from the RAF, as squadrons regrouped after Dunkirk in readiness for the Battle of Britain.
