The place Jack and Annie walked in with soldiers was a field hospital where located near the battlefield to treat wounded soldiers.

Annie wanted to be a volunteer nurse to help soldiers, but Jack just wanted to find the special writing for Morgan and go home, because the sad scene at the field hospital made him feel sick.

Anyway, they decided to be a volunteer nurse and got to have a list that they need to follow from the other nurse.

The list was what they were looking for : something to follow.

Jack and Annie’s duty as a volunteer nurse was to come in tents to feed soldiers' noon meal.

One of two tents they came in was for African-American and they met a desperate person who had been a slavery before the civil - war.

To lessen sorrow and give him a hope as the list contains, Jack gave him a courage by speaking that his descendants should be treated fairly some day.
