MANILA, P.I., AUGUST 18, 1898.
1. I have the honor to report that at 9 A.M. on August 13th, the Squadron left its anchorage at Cavite and took position off the city of Manila.
2. The Flagship OLYMPIA, RALIEGH, and PETREL then proceeded to shell the magazine,fort and entrenchments at Malate; an army column attacking from the Southward at the same time, accompanied by the gunboat CALLAO and tug BARCELO, well inshore. Commenced firing at 9:35 and ceased firing at 10:32, the fort being silenced and the enemy retreating into the city closely followed by the army advancing along the beach, with the CALLAO and BARCELO on its flank.
3. The other vessels of the Squadron took the positions assigned them opposite the principal batteries along the water-front, as did also the OLYMPIA, RALEIGH and PETREL after the reduction of the fort at Malate.
4. At 11:00 A.M., hoisted the international signal Do you surrender? and at 11:20 a white flag was seen on the city wall. After preliminary conference, General Merritt landed with 600 troops and arranged the terms of surrender.

A company of troops with a regimental band happening to be marching past, saluted the colors as they went up and played the national air. The vessels of the Squadron fired a national salute.
