This volume, like the others, claims only to be a contribution to the history of the Second World War.
The tale is told from the standpoint of the British Prime Minister, with special responsibility as Minister of Defence for military affairs. As these came directly to some extent into my hands, British operations are narrated in their scope and in some detail.
At the same time it would be impossible to describe the struggles of our Allies except as a background. To do full justice these must be left to their own historians, or to later and more general British accounts.
While recognising the impossibility of preserving proportion, I have tried to place our own story in its true setting.
