Holzauge ([ˈhɔlt͡sˌʔaʊ̯ɡə], "wooden eye", nickname for a spotter)[1] was a Wehrmacht weather station that was built by Nazi Germany after the occupation of Denmark during World War II.
On 22 August 1942, the fishing steamer Sachsen, which had been converted into a weather observation ship, landed in East Greenland.
The ship had set out from Tromsø with a Wehrmacht unit under the command of Lieutenant Hermann Ritter and a group of meteorologists led by Gottfried Weiss, totalling 17 men.
[2] On 13 March 1943, a gun battle occurred when the Germans were accidentally spotted by members of Nordøstgrønlands Slædepatrulje, during which Danish corporal (non-commissioned officer) Eli Knudsen was fatally wounded.
On 25 March, the headquarters of the Eskimonæs sledge patrol near the southern tip of Clavering Island, about 95 kilometres (59 miles) southwest, was partially destroyed by the Germans.
