How does wilfred Owen use aristotle's three rhetorical appeals to convince us of his claim that the phrase dulce et decorum estpro patria mori lacks merit?

The main argument that Owen uses in "Dulce et Decorum est" is an emotional argument, by describing the pain of the soldiers and a horrific death and irreverent handling of a corpse. His appeal to authority is the fact that he was a soldier and witnessed this Horror and found that a military death is anything but sweet. His logical argument is that war is often glorified by those who have not fought it, but the reality is tragic and vulgar, and children should be made aware of that so they can avoid it.
