The difference in perspective in the two accounts helps to communicate the different messages. "The Battle of Greasy Grass" focuses on the significance of the battle for Indigenous-U.S. relations, and as such, emphasizes the impact of the battle on the Indigenous community. On the other hand, "The Little Horn Massacre" focuses on the United States' defeat and the negative consequences for the U.S. military. The two accounts have the same general purpose of discussing the battle, but the different perspectives highlight different aspects of the event and lead to different conclusions. The author's perspective influences the way in which they present the events and interpret their significance, which in turn helps communicate the different messages.
