IT is not a analogy so it has to be a category.
"In Flanders Fields" and "Dulce et Decorum Est!" both use the same event but they reveal completely different views of World War 1. In the first mentioned story author shows his respect to those who was fighting for their country and future generations, persuading the reader to feel the same and to be ready to protect their motherland. Author of the second story describes all the frightening moments of war and convinces the readers that it if they had to stand on the front line it would be the worst experience in their life. So, In Flanders Fields" eulogize war while "Dulce et Decorum Est!" warrns against it.
