Watson, Philip Their Greatest Hour. The Rearguard Action of the 12th Lancers Dunkirk 1940

There can be few military stories which have been written about in such great detail. The story of Dunkirk has found its way into the British consciousness to such a degree that it has come to epitomise the very essence of Britishness at times of national hardship.
The phrase "Dunkirk Spirit" has been used to define the British character. Cartoons of the day re-defined the abbreviation of the British Expeditionary Force (BEF) to mean Bravery, Endurance, and Fortitude!

This has been the prevailing national narrative of May 1940. A story of small boats that came to the rescue of a stranded Army on the beaches of Dunkirk: brave soldiers who would have died, or been captured had it not been for the flotilla that came to their rescue. This is supported by strong images of stoic British soldiers waiting patiently on the beaches for deliverance.
Historians have subsequently identified other factors which contributed to the success of Operation Dynamo. These include the mild weather and calm sea, as well as the use of the East Mole for the large ships. The smoke which hung in the air as a result of the German shelling and bombardments helped mask the BEFs activities, and Hitlers earlier somewhat unexpected "Haltebefehl" gave the BEF time to consolidate its bridgehead at Dunkirk. However, if Gorts statement as quoted by Shand is true, that "without the Twelfth Lancers only a small part of the Army would have reached Dunkirk", then it would appear there is another element of the story which is still to be told. It was to account for the five Battle Honours the Regiment would win in just 21 days.
