Directly in front of the cavalry division was a little hill occupied by a Spanish force. This hill is called in General Wood's report East Hill, but in the literature of the battle it is usually mentioned as Kettle Hill. The fire in part was coming from here. Colonel Wood gives another report of the morning's experience in which he says: "The brigade moved down the road toward Santiago in rear of the First Brigade, with instructions to deploy to the right after crossing the San Juan, and continue to extend to the right, reaching out toward General Lawton's left and holding ourselves in rear of the First Brigade as a support. On reaching the stream the First Volunteer Cavalry, which was in the lead, crossed the stream with comparatively slight loss and deployed to the right in good order, but at this time a captive balloon was led down the road in which the troops were massed, and finally anchored at the crossing of the stream. The approach and anchoring of this balloon served to indicate the line of approach of the troops and to locate the ford, and the result was a terrific converging of artillery and rifle fire on the ford, which resulted in severe loss of men. Under this fire the First United States Cavalry and the Tenth United States Cavalry crossed the stream and deployed to the right where they were placed in position in rear of the First Brigade. Two regiments of the Second Brigade, to wit., the First and the Tenth Regular Cavalry, were located in the rear of the First Brigade. The First Regular Cavalry had begun its day's work as support of Grimes' battery, but had later come forward and taken its place in the brigade time enough to join in the action that followed.
