Theodore Roosevelt (18581919). The Rough Riders. 1899.
[Owing to the circumstances of the regiment's service, the paperwork was very difficult to perform. This muster-out roll is very defective in certain points, notably in the enumeration of the wounded who had been able to return to duty. Some of the dead are also undoubtedly passed over. Thus I have put in Race Smith, Sanders, and Tiffany as dead, correcting the rolls; but there are doubtless a number of similar corrections which should be made but have not been, as the regiment is now scattered far and wide. I have also corrected the record for the wounded men in one or two places where I happen to remember it; but there are a number of the wounded, especially the slightly wounded, who are not down at all.]
As said above, this is not a complete list of the wounded, or even of the dead, among the troopers. Moreover, a number of officers and men died from fever soon after the regiment was mustered out. Twenty-eight field and line officers landed in Cuba on June 22d; ten of them were killed or wounded during the nine days following. Of the five regiments of regular cavalry in the division, one, the Tenth, lost eleven officers; none of the others lost more than six. The loss of the Rough Riders in enlisted men was heavier than that of any other regiment in the cavalry division. Of the nine infantry regiments in Kent's division, one, the Sixth, lost eleven officers; none of the others as many as we did. None of the nine suffered as heavy a loss in enlisted men, as they were not engaged at Las Guasimas.
No other regiment in the Spanish-American War suffered as heavy a loss as the First United States Volunteer Cavalry.
