“The _Olympia_ being short of officers for the battery, Ensign H. H. Caldwell, flag secretary, volunteered for and was assigned to a subdivision of 5-inch battery. Mr. J. L. Stickney, formerly an officer in the United States navy, and now correspondent of the _New York Herald_, volunteered for duty as my aid, and did valuable service. “I desire specially to mention the coolness of Lieut. C. G. Calkins, the navigator of the _Olympia_, who came under my personal observation, being on the bridge with me throughout the entire action, and giving the ranges to the guns with an accuracy that was proved by the excellence of the firing. “On May 2d, the day following the engagement, the squadron again went to Cavite, where it remained. “On the 3d, the military forces evacuated the Cavite arsenal, which was taken possession of by a landing party. On the same day the _Raleigh_ and _Baltimore_ secured the surrender of the batteries on Corregidor Island, paroling the garrison and destroying the guns. “On the morning of May 4th the transport _Manila_, which had been aground in Baker Bay, was towed off and made a prize.” List of the two fleets engaged at the battle of Manila Bay, together with the officers of the American fleet:(2) AMERICAN FLEET.
