The character who was awarded the Victoria Cross was based on Flight Lieutenant Eric James Brindley Nicolson of fighter squadron 249. The citation reads:
"During an engagement with the enemy near Southampton on 16th August 1940, Flight Lieutenant Nicolson's aircraft was hit by four cannon shells, two of which wounded him whilst another set fire to the gravity tank. When about to abandon his aircraft owing to flames in the cockpit he sighted an enemy fighter. This he attacked and shot down, although as a result of staying in his burning aircraft he sustained serious burns to his hands, face, neck and legs. Flight Lieutenant Nicolson has always displayed great enthusiasm for air fighting and this incident shows that he possesses courage and determination of a high order. By continuing to engage the enemy after he had been wounded and his aircraft set on fire, he displayed exceptional gallantry and disregard for the safety of his own life."
The above-mentioned action was the first time that Nicolson had ever engaged the enemy.
In 1942 he was posted to India and promoted to Wing Commander and Squadron Commander of a group of twin-engine Bristol Beaufighters (a robust multiple-mission attack aircraft), where he was awarded the Distinguished Flying Cross. In May of 1945, at the age of 28, while flying as an observer in a B-24 Liberator, the plane caught fire and the crew was lost in the Bay of Bengal.
We'll have lunch and a drink. I'm sure you could do with a drink, Major-General.
Major General Bernard Montgomery: I neither drink nor smoke, and am 100% fit.
Winston Churchill: Well I both drink and smoke, and I'm 200% fit.
Clement Attlee was played by a Scottish actor with a Scottish Accent. In fact he was born in Putney, South West London and therefore did not have a Scottish accent.
