There had previously been a difference of opinion between Captain Lee and myself in regard to the dimensions that should be given to the embrasures. The Chief Engineer decided in favor of Captain Lee, and the embrasures were changed and made to conform to his views. In a very short time after the firing began one of the embrasures became so badly choked that it could not be used until the _debris_ could be removed. Hastily renewing the blindage of brush-wood that had been used to conceal the work from view of the enemy during the construction, the detail of engineer soldiers then on duty, in the battery, cleared the embrasure of the obstructions, removed the blindage, and the gun resumed its fire. Just after that incident, I asked Captain Lee what he now thought in regard to the proper dimensions for the embrasures. He replied: "They must be made greater when the battery is repaired to-night." The naval detachment had only forty rounds of ammunition; which was expended in about three hours, and the firing had to cease until the arrival of the next naval detachment. The latter when it came into the battery, had only forty rounds of ammunition and was to serve until relieved, the next afternoon by a third naval detachment. Before the ammunition of the first detachment was expended the embrasures were all in a very bad condition--the battery was almost entirely unserviceable; and before the second detachment arrived I caused the embrasures to be filled up, until the battery could be repaired that night and put in good condition for re-opening the next day. The second naval detachment came into the battery about the middle of the afternoon. The naval captain in command, without consulting me, ordered the embrasures to be cleared at once, with the intention of immediately opening fire. Perceiving what was being done by the sailors in re-opening the embrasures, I ordered them to stop; and asked by whose authority they were acting. On being informed that their orders came from the commander of the detachment, I asked them to point him out to me. I immediately introduced myself to him, as the engineer officer in full charge of the construction of the battery, and told him if the embrasures were cleared the battery would still be unfit for service--that it could not be repaired until that night, and would then be put in better condition than it was when it first opened. The army gun battery would be ready next morning; and its fire, combined with that of the naval battery, after the latter was put in good condition, would be very effective. But, if the naval detachment opened fire that afternoon, the battery being unfit for service, its ammunition would be exhausted before night without hurting the enemy; and the battery would necessarily be silent the next day, when the army battery would open its fire. The naval captain insisted that the embrasures should be cleared at once, and the firing resumed.
