Life at the front is hard and harsh, but only one law, as ancient as the world, rules there: “Kill, or you will be killed.” Your enemy is sitting only a hundred paces away and is aiming at you. But you also know where he is and what needs to be done with him... In the rear there is a completely different, peaceful life. But here too there is a war and also a front. He is invisible, but the blood shed is real. The fifth column is working off the advances it has received and boasting of its meanness. And even if they are not wearing a feldgrau, they are just as enemies. And, as it was once said, if the enemy does not surrender, he is destroyed. And the “etoile” of the demi-monde, available at a reasonable price, and a gang of revolutionaries who staged an attack on an ambulance train in order to kidnap the emperor’s daughter.
