9. "Then to my amazement I saw that the surgeon, who I knew had served in the Civil War, attending the wounded... from the Wilderness
to Appomattox, began to grow pale..." (Paragraph 29). How does
quote contribute to the development of ideas in the text?

The quote tries to tell us how horrible the scene was. It says the surgeon  began to grow pale.

This quote was taken from the wounded knee massacre. The wounded knee massacre was a slaughter of Native Indians in the United States of America who had tried to take back their ancestral lands.

This narrator described the surgeon as going pale from the number of women and children he saw that were fatally shot.

This contributes to the development of ideas by giving us ideas on how horrible and gruesome the scene of the murder and the action that happened in the place.
