The stories about the events at the German-Russian border sound so incredible that Bernhard Hoeft ultimately wants to see it with his own eyes. In 1915, the journey takes the author through East Prussia to the border town of Prostken. There is little to see of the great war until he feels it. In the distance, an indistinct dull rumble. It made him shudder. It had to be the front. He only knew it by hearsay. When he receives an invitation from a lieutenant colonel, he steps onto the battlefield for the first time, the fortress of Ossowiec. Now he sees the traces of war. Bernhard Hoeft enters the battlefield, the fortress of Ossowiec. He gets to know the trenches of the front. Everywhere he sees the devastation of the Russian invasion of East Prussia. He sees German refugees and destroyed places. Bernhard Hoeft meets the famous Swedish Tibet researcher and ardent friend of Germany, Sven Hedin, the author of the book "A People in Arms.".
