In 1898 however, the Spanish–American War broke out, and John Englis was purchased by the United States Army for use as a hospital ship.
[1] Renamed Relief the ship was found to have insufficient coal capacity for safe trans Pacific navigation and was confined to Philippine waters based in Manila where as of 1 January 1900 she was reported to be a "floating hospital" with 107 sick and wounded after a trip to outlying areas.
President Theodore Roosevelt's desire that a hospital ship accompany the Great White Fleet on its round-the-world voyage led to his endorsement of the Bureau of Medicine and Surgery viewpoint.
Relief's staff provided expert medical care, treatment, and consultations for the more than 14,000 officers and men of the Great White Fleet until detached in November 1908 at Olongapo, Philippines.
She subsequently served under foreign flags as Hai Ning and Mindanao until transferred to Philippine registry during 1937 and named Lanao.
