Although seventy-eight years have passed since the Battle of the Somme was fought, interest in this, the bloodiest battle of the First World War, has never waned. Ray Westlake has collated all the information so painstakingly gathered, to produce a comprehensive compendium of the exact movements of every battalion involved in the battle. This book is invaluable not only to researchers but to all those visiting the battlefield and anxious to trace the movements of their forbears.
