In order to inspire everyone's fighting spirit, Churchill issued a general order to government officials: "In this dark day, the Prime Minister will be grateful if all colleagues and important officials in the government can maintain high morale around them; This is not to reduce the seriousness of the situation, but to express our confidence in our ability. We have unshakable determination to continue fighting until the enemy's ambition to rule the whole of Europe is completely shattered.
