Britain, an island nation, has come under attack many times. Phil Harris tells the story of the invasions of Britain from Caesar to Hitler. A historical account of the invasions that made Britain what it is today. 2010 is the 70th anniversary of the failed Operation Sealion. Romans, Vikings, Anglo-Saxons, Celts and Normans are all part of the DNA of Britain. An island nation, the British have only occasionally been under threat of invasion and the seas around our coasts have kept away all but the most determined of attackers. Many have tried and failed to take Britain. The Romans' first soiree into England was a short-lived affair, while the Vikings and Normans made Britain a permanent home.

In more recent times, the Spanish, the French and the Germans have all attempted to attack Britain and failed. In this seventieth anniversary year of the failure of Operation Sealion, the Nazi attempt to invade and control all of Europe, Phil Harris takes us on a readable account of the Invasions of Britain, both real and attempted, looking at the reasons for success or failure and how the mix of people who have come to Britain by force have helped make the nation it is today.
