In 1933 the
international court of the
League of Nations ruled in the Danish-Norwegian dispute over
Erik the Red's Land that for it to remain Danish, Denmark had to assert its sovereignty there. Initially, this presence was in the form of two fixed police stations. The Sirius Dog Sled Patrol, first known as the North-East Greenland Sledge Patrol, was activated in the summer of 1941 during
World War II to conduct long-range reconnaissance patrols along the northeast coast of
Greenland thereby preventing German presence there. Its headquarters was at
Eskimonæs, which had been until then a scientific station. At the time, the Germans established a number of secret
weather stations on the eastern coast of the island to provide them with invaluable meteorological information, both to assist their
U-boat campaign and to predict the weather in the
European theatre. Thus the patrol's discovery of these stations denied Germany such information with significant implications both for the
Battle of the Atlantic and for air and land fighting in
Europe, despite the enormous distance of Greenland from the main theatres of war. The Sirius Dog Sled Patrol cooperated with
Nanok East Greenland Fishing Company, the only other organization active in the remote area, which built a number of hunting huts in the uninhabited expanses of north eastern Greenland. In 2008, the
National Bank of Denmark issued a 10-
DKK commemorative coin of Sirius. On 16 September 2023, an unwitnessed
tsunami resulting from the
2023 Greenland landslide struck the northern part of
Ella Island, penetrating inland and devastating the Sirius Dog Sled Patrol station there, washing much of it into the sea. The station was closed for the winter, and no one was present when the wave hit. The
cruise ship Ocean Albatros arrived on the scene on 17 September and contacted the
Joint Arctic Command with the first report of the damage. On 19 September, personnel from the Sirius Dog Sled Patrol and the
Royal Danish Navy patrol vessel began clean-up and salvage work at the site, which they completed by 21 September despite a 20 September warning by officials to ships in the area to avoid putting crew members or passengers ashore because of a risk of additional tsunamis. == Organization ==
