The British Retreat From Dunkirk (LARGE IMAGES)

Remains of the day. Abandoned anti-aircraft guns and corpses on the streets of Dunkirk

Everybody knows about Dunkirk. How the British left its arms and hastily evacuated its men from a defeated France on anything that floated on water in 1940. But what till this day remains a mystery (there are many theories) is why did the Germans just sit and watch while the British were fleeing? If Hitler had sent his panzers and dive bombers there would have been a carnage of British soldiers. Perhaps Britain would have never recovered from it and there would never have been a D-Day in June 1944.
 Why? One of Hitler's monumental mistakes?

MORE ON MAJ-GENERAL MORVEN FORTUNE

The 51st Division remained in France after the general evacuation from Dunkirk, having been assigned to the French X Corps. After naval evacuation proved impossible and supplies of ammunition had been exhausted, Major General Fortune was forced to surrender the greater part of the Highland Division at St Valery en Caux. One brigade had earlier withdrawn to Le Havre and avoided capture.

 General Fortune spent the rest of the war as a prisoner of war. As senior British officer in captivity in Germany, he worked to improve the conditions of the men under his command. He suffered a stroke in 1944 but refused repatriation. He was finally liberated in April 1945 and made KBE shortly after.

Several writers have questioned the decision to remain with the French during the battle. However, General Charles de Gaulle stated, 'For my part, I can say that the comradeship of arms, sealed on the battlefield of Abbeville in May–June 1940, between the French armoured division, which I had the honour to command, and the gallant 51st Scottish Division under General Fortune, played its part in the decision which I made to continue the fight at the side of the Allies, to the end, come what may'. And he concluded by quoting the old motto of the Compagnie Ecossaise: 'omni modo fidelis' - 'faithful in every way'
