Both poems explain war. "Dulce et Decorum Est" brings you deeper into the battle and the effects the war has had on the soldiers. "The Man He Killed" states, "Had he and I but met By some old ancient inn, We should have sat us down to wet Right many a nipperkin" (710). Overall the message you get is when at war you do what you have to do in order to survive. "Men marched asleep," as stated in "Dulce et Decorum Est" showing the reader they continued on as it was part of their mission, not to give up (887).
Each poem carry's the tone of telling a story, how things are. The writer's are not necessarily upset but they attempt to explain the best they know how to make the reader feel a part of the poem and understand the message they want to share.
