Says Mr. Bonsal: "The moment the advance was ordered the black troopers of the Tenth Cavalry forged ahead. They were no braver certainly than any other men in the line, but their better training enabled them to render more valuable services than the other troops engaged. They had with them and ready for action their machine guns, and shoved them right up to the front on the firing line, from where they poured very effective fire into the Spanish trenches, which not only did considerable execution, but was particularly effective in keeping down the return fire of the Spaniards. The machine guns of the Rough Riders were mislaid, or the mules upon which they had been loaded could not be found at this juncture. It was said they had bolted. It is certain, however, that the guns were not brought into action, and consequently the Spaniards suffered less, and the Rough Riders more, in the gallant charge they made up the hill in front of them, after the Tenth Cavalry had advanced and driven the Spaniards from their position on the right." Corporal W.F. Johnson, B Troop, was the non-commissioned officer in charge of the machine guns during the brief fight at Las Guasimas, and his action was such as to call forth from the troop commander special mention "for his efficiency and perfect coolness under fire." Here I may be pardoned for calling attention to a notion too prevalent concerning the Negro soldier in time of battle. He is too often represented as going into action singing like a zany or yelling like a demon, rather than as a man calculating the chances for life and victory. The official reports from the Black Regulars in Cuba ought to correct this notion. Every troop and company commander, who has reported upon colored soldiers in that war, speaks of the coolness of the men of his command. Captain Beck, of Troop A, Tenth Cavalry, in the Guasimas fight, says: "I will add that the enlisted men of Troop A, Tenth Cavalry, behaved well, silently and alertly obeying orders, and without becoming excited when the fire of the enemy reached them." The yell, in the charge of the regulars, is a part of the action, and is no more peculiar to Negro troops than to the whites, only as they may differ in the general timbre of voice. Black American soldiers when not on duty may sing more than white troops, but in quite a long experience among them I have not found the difference so very noticeable. In all garrisons one will find some men more musically inclined than others; some who love to sing and some who do not; some who have voices adapted to the production of musical tones, and some who have not, and it is doubtless owing to these constitutional differences that we find differences in habits and expressions. Lieutenant Miley, of General Shafter's staff, in his description of the departure of General Shatter from General Garcia's tent, gives us a glimpse of the character of the men that composed the Cuban army in that vicinity.
