Final answer:
The Buffalo Soldiers, along with Roosevelt's Rough Riders, took San Juan Hill during the Spanish-American War.
Step-by-step explanation:
The Battle of San Juan Hill took place during the Spanish-American War in 1898. Before Teddy Roosevelt arrived, both the Spanish and Cuban revolutionaries were involved in the struggle for control of the hill. However, it was the Buffalo Soldiers, specifically the 9th and 10th Cavalry Regiments of African-American soldiers, who played a crucial role in securing the victory on San Juan Hill. They fought alongside the Rough Riders, a volunteer cavalry unit led by Roosevelt, and their efforts were instrumental in the American success at the battle.
