About six o’clock in the morning on May 12, 1898, the CALLAO entered Manila Bay, and was headed for the harbor. The RALEIGH weighed anchor and started for the vessel. When it determined that the vessel was a Spanish gunboat, RALEIGH, OLYMPIA and BALTIMORE opened fire on her. The CALLAO, hopelessly outgunned, lowered her colors and raised a white flag. The surprised crew later commented that they did not realize that they were being fired upon immediately, believing instead that the American vessels were actually the Spanish squadron at target practice.
The CALLAO’s crew and personal effects were landed at Cavite and paroled. It was later rumored that the commander of the gunboat was sentenced to be executed for not battling the American vessels.
The CALLAO was immediately pressed into service by the Americans, with Lt. B. Tappan in command, though the actual commissioning did not occur until July 17, 1898. For the remainder of the war, the vessel served as a tender for Rear Admiral George Dewey’s flagship, OLYMPIA. During the final assault on Manila, the shallow-draft CALLAO was stationed close inshore, off of fort San Antonio. Her 37 mm gun was put to use, to the appreciation of General Merritt and his men.
After the conclusion of the Spanish American War and the beginning of the Filipino Insurrection, CALLAO patrolled the Philippine coastal waters to suppress smuggling, aid the army in its operations, transport troops, provide support fire, etc. On February 21, 1901, CALLAO was decommissioned for repairs.
On December 20, 1902, the vessel was recommissioned, and ordered to carry supplies around Philippine waters. In February 1903, CALLAO began thirteen years of service along the Chinese coast and rivers. She was finally decommissioned at Hong Kong on January 31, 1916, and was laid up at Olongapo, Luzon.
The CALLAO returned to service in June of 1921, serving as a ferry until being sold on September 13, 1923.
