His greatest work, “Dulce et Decorum Est” is written based on an encounter with a gas attack and a soldier “guttering, choking and, drowning.” It illustrates the hardship he and his fellow soldiers were going through as they were “coughing like hags” and “cursing through sludge”. The shells would drop and they would instantly be flooded with gas. Owen makes it clear that this is the part of war that people don’t see. The part that isn’t so glorious after all and that “you would not tell with such high zest, To children ardent for some desperate glory.” The last lines of poem says, “Dulce et Decorum est Pro Patria Mori”, which means “it is sweet and right to die for your country” in Latin, saying that is is an “old lie”.Owen had a talent of graphically illustrating the horrors of war and bringing the reader into the setting visually in his poetry. The soldiers in “Mental Cases” suffer hallucinations in which they observe everything through a haze of blood: “Sunlight becomes a blood-smear; dawn comes blood-black.” In “Exposure,” which displays Owen’s mastery of assonance and alliteration, soldiers in merciless wind and snow find themselves overwhelmed by nature’s hostility and unpredictability.In “Disabled”, Owen also brings up the false ideas that people have about the nature of war. Owen creates a great amount of sympathy for the soldier by using various techniques and poetic devices. The poem starts with a description of the man who is “legless, sewn short at elbow” and lonely. The reader flashes back to when the “Town used to swing so gay” and when good life was “before he threw away his knees”. This is worded in a way to express that it wasn’t just a regular old injury and instead was almost a pointless one.It is evident that by showing the horrors of war and directly addressing the ideas that people at home have about going off to fight for glory, Owen finds the propaganda machine of the time deplorable and feels that the men fighting for their country are being lied to about what going off to war really means. His poetry creates a strong sense of pity of war to give his audience a more realistic idea of what is actually happening in the hope that if people’s opinions on the war change, the war will end.
