Final answer:
The characters' changes in the story suggest the illusion of glory in wartime and the impact of war on family disagreements.
Step-by-step explanation:
One possible theme in the story is the illusion of glory in wartime. The character of the father and son in "Chickamauga" initially view war as adventurous and heroic, as shown by the use of words associated with war and warriors at the beginning of the story. However, by the end of the story, the vocabulary associated with war and warriors changes, suggesting a shift in their perception of war. Another theme related to the characters' changes is the impact of war on family disagreements. The experiences they have during wartime lead to a change in their perspectives, causing disagreements within the family. These changes suggest that the illusion of glory in war can be shattered by the harsh realities of conflict, and that war can strain family relationships. It highlights the negative aspects of war and challenges the idea of heroism and glory in battle.
