[4] She next joined Dolphin and Mayflower as one of the host ships for the Russo-Japanese Peace Conference (4–8 August) serving at Oyster Bay, New York; Newport, Rhode Island, and Portsmouth, New Hampshire.

She left the Puget Sound Navy Yard on 19 September 1913, touching San Francisco, Hawaii and Guam on her way to Cavite, where she joined the Asiatic Fleet on 2 November.

[4] Galveston's tour on the Asiatic Station was largely taken up with convoy service for supply ships and troop transports shuttling Marines and other garrison forces and stores between the Philippines and ports of Japan and China for the protection of American lives, property, and interests with brief intervals of Yangtze River Patrol for the same purpose.

[4] Galveston was assigned to Squadron 2 of the Atlantic Fleet Cruiser Force for convoy escort duties concurrent with the training of Armed Guard crews.

[4] She arrived in Plymouth, England, 26 March 1919; transported a contingent of British-American troops from Harwich to Murmansk, USSR as part of Allied intervention in the Russian Civil War there; then served as flagship of Squadron 3, Patrol Force, in Western European waters.

The end of this service was climaxed by a visit to her namesake city in Texas, where she arrived from Panama 26 August 1923 to represent the Navy at the American Legion convention.

Thereafter much of her time was spent cruising between that-port and Balboa to cooperate with the State Department in the restoration and preservation of order, and to insure the protection of American lives and property in Central America.

She resumed her watchful cruises between Balboa and Corinto until 19 May 1930 when she transited the Panama Canal for a last courtesy visit to Galveston (24–31 May) before inactivation overhaul in the Philadelphia Navy Yard.
