From daybreak to one P. M., over six hundred Paixhans shells and solid shot were fired into the city by the naval battery. Fort St. Iago, which had concentrated its fire on the army batteries, now opened on the naval redoubt, the guns of which were at once trained in the direction of the new foe. A few applications of the science of artillery proved the unerring accuracy of Perry’s pupils, and St. Iago was silenced. Captain Mayo and his officers through their glasses saw the Mexicans evacuate the fort. Chagrined at having no foemen worthy of their fire, he ordered both officers and sailors to mount the parapet and give three cheers. “If the enemy intends to fire another shot, our cheers will draw it,” said the gallant little Captain; but echo and then silence were the only answers. The naval guns having opened the breach so desired by General Scott and silenced all opposition, had now nothing further to do, were again left to cool. The naval battery had fired in all thirteen hundred rounds. At 2 P. M., Captain Mayo turned over the command to Lieutenant Bissell and mounted his horse, the only one on the ground, to give Commodore Perry the earliest information of the enemy’s being silenced. As he rode through the camp, General Scott was walking in front of his tent. Captain Mayo rode up to him and said “General, they are done, they will never fire another shot.” The General, in great agitation, asked “Who? Your battery, the naval battery?” Mayo answered, “No, General, the enemy is silenced. They will not fire another shot.” He then related what had occurred. General Scott in his joy almost pulled Captain Mayo off his horse, saying (to use his own expression) “Commodore, I thank you and our brothers of the navy in the name of the army for this day’s work.”[18] The General then went on and complimented in most extravagant terms the rapid and heavy fire of the naval battery upon the enemy; saying, when he was informed that Captain Mayo had sent to Perry for an additional supply of ammunition, that the post of honor and of danger had been assigned by him to the navy. The General’s remarks then became more personal. He said “I had my eye upon you, Captain Mayo, as Midshipman,[19] as a Lieutenant, as a Captain, now let me thank you personally as _Commodore_ Mayo for this day’s work.” The loss of the second day in the navy was one officer, Shubrick, and one sailor killed and three wounded. Lieutenant Shubrick’s monument stands in the Annapolis Naval Academy’s grounds.
