The coup efforts were supported by United States Government Minister John L. Stevens with an invasion of U.S. Marines, who came ashore at the request of the conspirators. The coup left the queen imprisoned at Iolani Palace under house arrest. It briefly became the Republic of Hawaii, before eventual annexation by the United States in 1898. Advised about supposed threats to non-combatant American lives and property by the Committee of Safety, Stevens obliged their request and summoned a company of uniformed U.S. Marines from the USS Boston and two companies of U.S. sailors to land on the Kingdom and take up positions at the U.S. Legation, Consulate, and Arion Hall on the afternoon of January 16, 1893. 162 sailors and Marines aboard the USS Boston in Honolulu Harbor came ashore well-armed but under orders of neutrality. The sailors and Marines did not enter the Palace grounds or take over any buildings, and never fired a shot, but their presence served effectively in intimidating royalist defenders. Historian William Russ states, "the injunction to prevent fighting of any kind made it impossible for the monarchy to protect itself. Due to the Queen's desire "to avoid any collision of armed forces, and perhaps the loss of life" for her subjects and after some deliberation, at the urging of advisers and friends, the Queen ordered her forces to surrender. The Honolulu Rifles took over government buildings, disarmed the Royal Guard, and declared a provisional government.
