Greenland Patrol The Greenland Patrol was a United States Coast Guard operation during World War II. The patrol was formed to support the U.S. Army building aerodrome facilities in Greenland for ferrying aircraft to the British Isles, and to defend Greenland with special attention to preventing German operations in the northeast. Coast Guard cutters were assisted by aircraft and dog sled teams patrolling the Greenland coast for Axis military activities. The patrol escorted Allied shipping to and from Greenland, built navigation and communication facilities, and provided rescue and weather ship services in the area from 1941 through 1945.
