Answer:
- Anger at the ignorance of civilians and leaders at home.
- The innocence and ignorance of enlisted soldiers.
In these excerpts, both of these themes are expressed. The fact that people at home are ignorant of the reality of war is obvious in the first excerpt as the author talks to the stranger telling the old lie of how great it is to die for your country. In the second excerpt, this is shown by how the author addresses the "smug-faced crowds."
The second theme is discussed in the first excerpt when the author talks about the "children ardent for some desperate glory." In the second excerpt, it is reflected by talking about the "youth and laughter" of the soldiers.
