This song tells a true story. Two best friends joined the army together during the First World War and spent most of their days side by side at the front. They went on every patrol, took part in every mission, and stood every guard duty together. Facing countless hardships, they always looked out for each other. One fateful day, during the German spring offensive, a shell struck the dugout where the two friends were stationed. One of them was killed, while the other woke up in a field hospital.
