Side by side ... the British and French peoples have advanced to rescue ... mankind from the foulest and most soul-destroying tyranny which has ever darkened and stained the pages of history. Behind them ... gather a group of shattered States and bludgeoned races: the Czechs, the Poles, the Norwegians, the Danes, the Dutch, the Belgians -- upon all of whom the long night of barbarism will descend, unbroken even by a star of hope, unless we conquer, as conquer we must; as conquer we shall.
