‘When the crocus blossoms,’ hiss the women in Berlin,
‘He will press the button, and the battle will begin.
When the crocus blossoms, up the German knights will go,
And flame and fume and filthiness will terminate the foe…
When the crocus blossoms, not a neutral will remain.’
(A P Herbert, Spring Song, quoted in To Lose a Battle, by Alistair Horne)
On May 10, 1940, German forces launched an attack against Belgium, France, the Netherlands, and Luxembourg. Few people among the Allies imagined that France would collapse in only six weeks: Churchill, for example, had a high opinion of the fighting qualities of the French army. But collapse is what happened, of course, and we are still all living with the consequences. General Andre Beaufre, who in 1940 was a young Captain on the French staff, wrote in 1967:
The collapse of the French Army is the most important event of the twentieth century.
