Final answer:
Captain Charles Young's 1903 leadership of Buffalo Soldiers in Sequoia National Park signifies a transition in the Buffalo Soldiers' duties, as they evolved from military engagements to protecting American National Parks.
Step-by-step explanation:
To strengthen the idea that the tasks of the Buffalo Soldiers changed over time, Dakotah can integrate the information that Captain Charles Young, the third African American to graduate from the US Military Academy, led other Buffalo Soldiers to Sequoia National Park in 1903. This fact is significant because it demonstrates a notable shift from their original duties of engaging in battles with Native Americans to more domestic responsibilities like serving as park rangers in the newly established National Parks. This piece of information from the passage highlights the evolving role of the Buffalo Soldiers over time, showing how their duties expanded beyond military engagement to include the protection and management of American National Parks.
