How does Wilfred Owen convey a perspective of war?

Wilfred Owen conveys a perspective of war through vivid imagery and sensory details in his poem 'Dulce et Decorum Est'. He uses descriptions of the brutal and exhausting conditions faced by soldiers, such as "soldiers cursed[ing] through sludge" and being "drunk with fatigue". Owen employs graphic imagery, like a soldier "flound'ring like a man in fire or lime", and onomatopoeic verbs such as "guttering, choking, drowning" to highlight the horrors of war. He directly addresses the reader to challenge the glorification of war, suggesting that if they experienced the same, they would not believe the "old lie" that it is sweet and fitting to die for one's country. Through these techniques, Owen creates an anti-war perspective that emphasizes the grim realities faced by soldiers.
