World War I is often considered the Great War. It was fought from 1914 to 1918 and is considered the bloodiest war humanity has ever waged so far. In just four years, an entire generation of young people was exterminated: approximately 16.5 million people lost their lives, even more were injured, and the rest who managed to survive were traumatized for life. One of the reasons why there were so many human casualties was the fact that World War I turned out to be the first trench warfare in history. The sense of permanent stalemate caused great disillusionment with the romantic idea of ​​war and the concept of the soldier was no longer that of an honorable warrior but that of a victim. The terrible experiences at the front profoundly traumatized the young soldiers, many of whom already had some poetic endeavors and consequently began to write trench poems. The best trench poets, such as Wilfred Owen, Isaac Rosenberg and Siegfried Sassoon, produced their best works only when they abandoned Rupert Brooke's conventional "Georgian" style and instead wrote realistically about the war and the situation on the front (Clausson). Wilfred Owen, perhaps the most famous trench poet, criticizes the Romantic ideal of sacrifice in his “gas poem” (Bloom) “Dulce et Decorum Est,” thus seeking to destroy “the charming decency of war” (Bloom 15 ). In the first stanza the young people are depicted as “old beggars” (Owen), who are in a trance-like state, lame, blind, drunk and deaf, too tired to be afraid of the sound of rifle shots, of the “outdated Five-Nines ” (Owen) behind them. They march to some place where they can rest. Then the gas attack shakes them: “Gas! Gas! Quick, guys! (Owen). Unfortunately, one man couldn't get it......in the center of the card...the line hadn't moved much for a long time and every attempt to break through failed miserably. Warfare before the First World War was one of chivalric and heroic ideals, in which soldiers gave their lives for noble causes and, in doing so, went down in history as honorable heroes. The high recruitment rate at the start of the Great War shows that in 1914 an entire generation of young people wanted to fight because they believed in the just cause. However, the soldiers quickly abandon and overcome this simplistic view and become aware that “the war is being deliberately prolonged by those who have the power to end it” (Sassoon). The tragedy of the First World War lies in the fact that so many people lost their lives, both as soldiers and as collateral damage, simply because of rival imperialism, which proves once again that humanity's greatest enemy is the 'man himself..
