The dawn of July 1 found the troops of Wheeler’s division bivouacked on the eminence of El Pozo. Kent’s division bivouacked near the road back of El Pozo. Grimes’s battery went into position about two hundred and fifty yards west of the ruined buildings of El Pozo soon after sunrise and prepared gun pits. Grimes’s battery opened fire against San Juan a little before 8 A.M. The troops of the cavalry division were scattered about on El Pozo Hill in the rear and around the battery, without order and with no view to their protection from the Spanish fire. This condition rectified itself when the Spaniards, after five or six shots by the American battery, replied with shrapnel fire at correct range and with accurately adjusted fuses, killing two men at the first shot After some firing soon after 9 A.M. Wheeler’s division was put in march toward Santiago. Crossing Aguadores stream, it turned to the right, under General Sumner, who was in command at that time owing to General Wheeler’s illness. Scattering shots were fired by the Spaniards before the arrival of the first troops at the crossing, but their volley firing did not commence until the dismounted cavalry went into position, crossing open ground. Kent’s division followed Wheeler’s, moving across the stream, and advanced along the road in close order under a severe enfilading fire. After advancing some distance, it turned off to the left. Lieutenant Ord (killed in battle) made a reconnaissance from a large tree on the banks of the stream. At about one o’clock, after a delay of nearly two hours’ waiting for the troops to reach their positions, the whole force advanced, charged, and carried the first line of intrenchments. They were afterward formed on the crest and there threw up intrenchments facing the second line at a distance of from five hundred to one thousand yards.
