Final answer:
The author uses first-person narration to express his own feelings about the war, providing a direct and personal perspective by sharing emotions and experiences through a character in the story.
Step-by-step explanation:
The author can express his own feelings about the war through the strategy of first-person narration. This narrative mode employs the use of pronouns such as I, me, and we, and allows the narrator, who is often a character in the story, to share personal experiences and emotions directly with the reader. An example of first-person narration can be seen in Mark Twain's work where the narrative voice is a character in the story, stating thoughts and feelings with sentences like “Mr. Bixby served me in this fashion once, and for years afterward I used to blush even in my sleep when I thought of it.” This approach provides an intimate perspective and can effectively convey the author's personal stance or emotional response to war.
