During this campaign, Samuelson's crew was the first group of Allied photographers to document Nazi crimes and the plight of concentration camp prisoners at Lenzing and Ebensee, two subcamps of the Mauthausen concentration camp in Austria.
Ebensee is surrounded by three picturesque lakes, the Traunsee, the Offensee and the Langbathsee.
In May 1945, Heslop was among the first American photographers to document evidence of Nazi crimes and the plight of surviving inmates at Ebensee, a subcamp of the Mauthausen concentration camp in Austria.
The construction of the Ebensee subcamp began late in 1943, and the first 1,000 prisoners arrived on November 18, 1943, from the main camp of Mauthausen and its subcamps.
