Step-by-step explanation:
The Battle of San Juan Hill is renowned as the most pivotal land battle during the Spanish-American War. This conflict saw US forces capturing the heights around San Juan in Cuba. Eventuating on July 1, 1898, the victory was led significantly by the African American infantry and the Rough Riders, a volunteer cavalry unit commanded by Theodore Roosevelt. Their triumph resulted in the encirclement of Santiago and played a considerable part in propelling Roosevelt to celebrity status, although the valor of the black troops who fought bravely alongside him was less recognized in public narratives. The conclusion of this battle, marked by strategic victories at sea and the capitulation of the Spanish naval fleet, contributed significantly to the end of Spanish rule in Cuba and the Americas.
