Chacun knows how soldier testimonies are a wealth of intelligence for the history of the Great War. The three carnets reproduced here show the originality of emanating from fighters from both camps. Hans Rodewald was German, Antoine Bieisse and Fernand Tailhades were French. Embraced by the enthusiasm of August 1914, the three fantassins quickly face up to the reality that produces a mixture of excitation, distress and compassion. Seriously injured, falling into the power of the adversary, they fear for their lives but are treated by hands that turn out to be broaternal. The three men experience humanity with those they have hitherto referred to with the agreed term of enemy. This book reveals the complexity and ambivalence of combatants’ thoughts. He again disproved the simplistic thesis that the hatred of the enemy would have overshadowed any other feeling. It shows that, under a ‘culture of war’ varnish, there was also a fuller ‘culture of peace’.
