Before we go any farther let us see just what the Tenth Cavalry did do in this fight.  That their action was highly meritorious admits of no doubt, and the laurels they won were never allowed to fade during the whole campaign.  General Wheeler speaks of them with the First Cavalry.  He says:  “I was immediately with the troops of the First and Tenth Regular Cavalry, dismounted, and personally noticed their brave and good conduct.”  There were four troops of the Tenth engaged, composing the First Squadron of that regiment, under command of Major Norval.  Troop A was commanded by Captain W.H.  Beck, who was specially commended by General Wheeler for good conduct.  Second Lieutenant F.R.  McCoy was Captain Beck’s assistant.  This troop moved over to the left, receiving the fire of the enemy, but making no response, the distance being too great for effective carbine firing.  This troop reached Colonel Wood’s right and made the line continuous so that there was now a force in front of that ridge where the Spaniards were securely entrenched and from which they were pouring their enfilading fire upon Colonel Wood’s line.  Troop A, although coming into the line, did not fire.  Their presence, however, gave the Rough Riders the assurance that their flank was saved.  Troop E was commanded by Captain C.G.  Ayres with Second Lieutenant George Vidmar.  This troop was placed by General Young in support of Captain Watson’s two Hotchkiss guns, and also of the troops in their front.  The troop was under fire one hour and a quarter, during which they were in plain view of the Spaniards, who also had their exact range.  One man was killed and one wounded.  Their courage, coolness and discipline in this trying hour and a quarter were of the very highest order.  The troop commander says:  “Their coolness and fine discipline were superb.”  This troop did not fire a shot.  Thus one-half of the squadron moved to its positions and held them without being able to do any damage to the enemy, as they were carrying out to the letter their instructions, which were to fire only when they could see the enemy.  Troop B was commanded by Captain J.W.  Watson with H.O.  Willard as Second Lieutenant.  A detachment of this troop was placed in charge of four Hotchkiss mountain guns.  This detachment opened fire upon the enemy, using the ammunition sparingly, as they had but fifty rounds with them.  Twenty-two shots were fired, apparently with effect.  The remainder of the troop under Lieutenant Williard was ordered to move out to the extreme right, which would place it beyond the line of the First Cavalry, thus bringing that regiment between Troop A of the Tenth, which connected it with the Rough Riders and Troop B, which was to be on its extreme right.  Lieutenant Williard’s report of this movement is as follows:
