Noah, Delphine, and Tilly have their picture made in Cairo right before Noah goes into battle.
Dr. Hutchings joins the army as a captain and doctor.
Noah and the rest of the Thirty-First Illinois regiment march and/or sail away to fight for control of the river, while Delphine, Tilly, and the rest of Cairo stay behind and wait.
Finally, the steamships return, carrying the wounded of the Battle of Belmont.
Dr. Hutchings finds Tilly and brings Noah to her.
Noah is missing his left arm, which Dr. Hutchings amputated and dropped overboard.
Because Noah will never be able to fight again, he is out of the army.
Tilly and Delphine take him to Mrs. Hanrahan's to nurse him until he is well enough to travel.
Tilly is afraid to send a letter home until she's sure Noah will live. Delphine tells her Calinda would not believe he's alive anyway, though, because she had a vision of a coffin coming up the river. You know, just in case we were starting to get comfortable.
