Konigsee sub-camp was established in 1944 near a residence built by order of Heinrich Himmler at Schönau for his mistress, Hedwig Potthast. According to the Dachau KZ blog, the sub-camp wasn't in existence for very long, being operated from 2nd to 9th September 1944. The camp held a mere 20 prisoners, all of them male, mainly builders. The aim of the camp was to renovate Himmler's mansion in Schneewinkl and an estate belonging to Grossadmiral Karl Doenitz. A bunker was also constructed. German nationals were also present at the construction sites, in various official capacities. The prisoners came from a number of European counries and were accommodated in a barn serving as a barrack. Accounts from former prisoners report that standards of food and medical care was usually quite good and also that there was some freedom of movement around the sites. There does not seem to have been any abuse of the prisoners and the SS staff and commanding officer were well behaved. There were three escapes from the camp. All three prisoners were subsequently recaptured. On 4th November 1944, Andreas Baier was caught and sent to the 'parent' camp at Dachau where he had to sew an 'Escape' patch on his clothing. Heinrich Weigand and Bertram Buchheit ran into a check-point at Berchtesgarden and were taken to a local jail. They were also, later, sent to Dachau (on 11th January 1945), but nothing more is known about their fate. It is known, however, that escapees were treated more severely than other prisoners.
