Six Armies in Normandy

This is an excellent book, a look at the Normandy campaigns by way of comparing and contrasting the six different armies that took part in it: the American, British, Canadian, French, Polish and German, Keegan using "armies" here in the sense of a national army, rather than as a specific type of military unit. It is not intended as a full chronicle of the D-Day landings and the campaign in Normandy and you will need some prior knowledge of them to make the most of this book. However, Keegan still includes enough context for the stories in this book to make sense and in the end you still get a rough history of the war in the west from D-Day to the liberation of Paris.
