Greenland was strategically important to the Allies in WWII for a number of reasons. First, a mine at Ivigtut was the only known source of cryolite, a vital catalyst for aluminum production. Second, Greenland was ideally located as a refueling stop for planes flying from North America to Europe in the days before non-stop trans-Atlantic flights. Finally, meteorologists had shown that by monitoring Greenland weather they could more accurately forecast weather for Western Europe. When Denmark, the colonial power in Greenland, fell to the Nazis in the spring of 1940, Britain, Canada, and the United States began working out how to defend Greenland.

The USS Bowdoin
Even before the United States was at war, the need to keep Germany out of Greenland led the government to establish a military presence there. In the spring of 1941, Donald B. MacMillan was asked to cancel his planned expedition and instead to turn the Bowdoin over to the Navy. In June, 1941, the USS Bowdoin left Portsmouth, NH, with a naval crew. They spent the next five months identifying suitable locations for radio stations and landing strips in West Greenland.
