After seeing the 'Buffalo Soldiers" on campaign and in battle-fearless, hardy, unstoppable-it was for the very spirit of the bold, tough animal that the men of the 9th U.S. Cavalry were admiringly named by their enemies, the Native Americans. "The Warning Shot" commemorates the African American soldiers' role in guarding the expanding boundaries of the United States as well as their continuing participation in today's modern U.S. Military. Print signed by Tracy Stivers.
