Born between 1885 and 1891, George Patton, Bernard Montgomery and Erwin Rommel all participated in the First World War and, like millions of others, were so affected by their wartime experiences that it became a fundamental influence on their lives. Yet none of the men were dissuaded by the carnage from seeking military careers when the guns finally fell silent. Each became wholly dedicated to the profession of arms and, being exceptional officers and leaders, they prospered. Despite the broad similarities between them, there were some marked differences in their approach to leadership due to the individuality bestowed on them from their genes, upbringing, life experience and relationships. This book reveals how these stimuli created three unique personalities which, in turn, each man came to draw from when they became among the most prominent officers in their armies.
