The "White Buses" (Swedish: Vita bussarna) was an operation undertaken by the Swedish Red Cross and the Danish government in the spring of 1945 to rescue concentration camp inmates in areas under Nazi control and transport them to Sweden, a neutral country. Although the operation was initially targeted at saving citizens of Scandinavian countries, it rapidly expanded to include citizens of other countries.
All told, an operational staff of about 300 persons removed 15,345 prisoners from mortal peril in concentration camps; of these 7,795 were Scandinavian and 7,550 were non-Scandinavian (Polish, French, etc.). In particular, 423 Danish Jews were saved from the Theresienstadt concentration camp inside German-occupied territory of Czechoslovakia, contributing significantly to the fact that casualties among Danish Jews during the Holocaust were among the lowest of the occupied European countries.
The term "white buses" originates from the buses having been painted white with red crosses, to avoid confusion with military vehicles.
Inspired by this operation, the Norwegian White Buses Foundation organises excursions to Sachsenhausen and the sites of other concentration camps for school classes, accompanied by first-hand witnesses and survivors.
Denmark and Norway were invaded by Germany on 9 April 1940. A number of Norwegians were immediately arrested, and two months later the occupying force established the first prisoners' camp at Ulven, outside Bergen.
As tensions intensified between the Nazi authorities and the resistance, increasing numbers of Norwegians were arrested and detained in Norwegian prisons and camps; and later deported to camps in Germany. The first groups of Norwegian prisoners arrived in Sachsenhausen camp in early 1940.
