What does Henry plan to do when he goes home? Explain the last line of Chapter 15.

Henry plans to go home and spe his time telling war stories.

After this incident, and as he reviewed the battle pictures he had seen, he felt quite competent to return home and make the hearts of the people glow with stories of war.

The final sentence alludes to his stories and their audience.... young ladies, swooning over heroics and daring.

He saw his gaping audience picturing him as the central figure in blazing scenes. And he imagined the consternation and the ejaculations of his mother and the young lady at the seminary as they drank his recitals. Their vague feminine formula for beloved ones doing brave deeds on the field of battle without risk of life would be destroyed.
