Quinnebaug reported to the Atlantic Mine Force and was ordered 13 May 1918 to Invergordon, Scotland for mining operations in the North Sea with Mine Squadron 1. From 14 July to 26 October, she successfully completed ten mining missions screened by British destroyers of the 14th Flotilla (Grand Fleet). Quinnebaug was not diverted from her mission by two encounters with German submarines 20-21 September, and succeeded in planting approximately 6,040 mines in the Northern Barrage. Upon completion of this duty she returned home, decommissioned at Philadelphia 6 February 1919, and was returned to her owner 19 March 1919.
