Edited sentence: At this time, Ritscher and his team began mapping the region, claiming a large section of Antarctic coastal lands between 20°E and 10°W for Nazi Germany.Norway disputed Germany's claim of New Swabia, as it significantly overlapped a portion of Queen Maud Land, to which the Norwegian expedition had already laid claim five days earlier.Ritscher named this area New Swabia (), for the German region of Swabia.The 57-member expeditionary team assembled in Hamburg, Germany, and departed on 17 December 1938 aboard the Schwabenland, a freighter capable of carrying and catapulting aircraft.The Third German Antarctic Expedition was a covert military mission, ordered by Hermann Göring.The expedition employed two Dornier Wal aircraft, which made a total of 16 flights, mapping over 600,000 square kilometers, and taking more than 11,000 aerial photographs.The team made landfall in Antarctica on 19 January 1939, only five days after the arrival of a Norwegian expedition.The team returned to Germany in February 1939.The territory was to be employed for various purposes, including the establishment of a whaling station as part of a plan to increase Germany’s production of whale oil in advance of the anticipated war.This was the first attempt by any nation at large-scale aerial mapping of Antarctica.To support the German claim, the flight crew dropped 13 aluminum darts topped with the swastika flag from the aircraft as they photographed the region
