Casualty numbers for African-American units in the Spanish American War are sketchy. Of the four primary "Buffalo Soldier" units--the 9th U. S. Cavalry Regiment, the 10th U. S. Cavalry Regiment, the 24th U. S. Infantry Regiment, and the 25th U. S. Infantry Regiment--I have been able to determine the following: 

• The 9th mustered in with 46 officers and 984 enlisted men and mustered out with 46 officers and 869 enlisted men.
• The 10th U. S. Cavalry suffered seven deaths and 69 wounded at the Battle of San Juan Hill. One of their white officers was young Lieutenant John Pershing, the future World War I general known as "Black Jack."
• One African-American soldier was killed at the Battle of Las Guasimas.
• Approximately 30 Buffalo Soldiers were killed at the Battles of Caney and San Juan Hill on July 1, 1898.
