The Scum of the Earth follows the men Wellington called just that from victory at Waterloo to a Regency Britain at war with itself, and explodes some of the myths on the way; such as that the defeat of Napoleon ended the threat of revolution spreading from France. Did the victorious soldiers return to a land fit for heroes? They did not. In 1819, the Peterloo massacre saw 15 killed and at least 500 injured when cavalry sabred a crowd demanding parliamentary reform. Peace in Europe perhaps for 50 years—but at home, repression and revolution in the air. And at the same time, the sheer exuberance of the Regency period, with new buildings, new art, even 17 new colonies more or less accidentally acquired. By 1848 the whole of Europe was once more set for complete upheaval. There is no one better to take a cold, hard look at the battle itself and its aftermath, in order to save us from an anniversary of misty-eyed backslapping, than political editor Colin Brown.
