Final answer:
The biography by Sarah Bradford portrays Harriet Tubman as a Moses-like figure, using religious references to highlight her heroism, whereas the nurses' letters from the World Wars provide personal insights into their experiences, contrasting the biographical narrative with real-life accounts.
Step-by-step explanation:
Harriet Tubman is exemplified as a heroic figure in Sarah Bradford's biography Scenes in the Life of Harriet Tubman. Bradford's characterization likens Tubman to Moses, framing her efforts and the Underground Railroad within a religious context, comparing her to legendary and saintly female figures for her courage and the liberation of her people. On the other hand, the letter written by nurses during World War I and II offers a personal and direct account of their experiences, contrasting with the third-person narrative and historical focus found in Bradford's biography.
The biography and the letter serve different purposes; the former provides a historical account and celebration of Tubman's life and actions, while the latter presents firsthand personal narratives of the nurses' roles in war. Bradford employs religious imagery to equate Tubman's struggle with biblical deliverance, while the nurses' letters convey the immediacy and personal impact of their experiences in a more straightforward manner.
