Answer:
The glory of nature and of a young hero's death
The color of summer and memories of war
Step-by-step explanation:
When the narrator begins to describe their memory, he or she focuses on the setting, putting emphasis on nature's attributes on a specific moment of summer, full of bright colors ("copper-red grass" "sunlight" "red gold", "rosy") which makes it seem praiseworthy and glorious, and then the speaker ends up connecting that moment with the glory of the war and a young hero's death.
