After VE Day, Eileen Younghusband, a WAAF officer and fluent French-speaker, acted as a guide to RAF personnel visiting the camp. She had been in Germany prior to the start of the war, and had encountered fleeing Jews. During the German bombing of Britain, she had been a radar filter officer giving warning of air raids. When the German V-2 ballistic missile attacks on London and elsewhere began in 1944, she was sent to Belgium with mathematicians to help locate V-2 launch sites. Fort Breendonk was briefly repurposed as an internment camp for Belgian collaborators. This period of the Fort's existence is known as "Breendonk II". The internees were moved to Dossin Barracks, Mechelen, on 10 October 1944. Later significance War crimes trials Trials of the Flemish SS guards, considered Nazi collaborators, were held during 1946 in Mechelen and including some guards and officials at Fort Breendonk. Of those who were convicted, 18 were sentenced to be executed by firing squad in 1947, two of which appealed their case and had their sentences revised to life imprisonment. Four others were sentenced to life in prison, one to 20 years in prison, and one other was acquitted, and two guards who were sentenced to life were never found. The Nazi camp commandant, Philipp Schmitt, was tried in Antwerp in 1949 as a war criminal; the court martial sentenced him to death and was shot by a firing squad on 9 August 1950. He never showed any remorse and denied all of the atrocities that occurred at Breendonk, claiming he was merely re-educating the inmates as he had been ordered. Museum and memorial In 1947 Fort Breendonk was declared to be a national memorial, recognizing the suffering and cruelty that had been inflicted on Belgian prisoners during World War II. The fort is now a well-preserved example of the prison camps operated by Nazi Germany and a national museum. The Fort is open to visitors all year round and is located close to the A12 Brussels-Antwerp motorway. Pictures of working Nazi internment camps during the war are rare and, for a long time, it was believed that absolutely no pictures of Breendonk during the war existed. But in the early 1970s a batch of photos of the camp was discovered in the possessions of Dutch photographer Otto Spronk. He had collected thousands of pictures and films of the Third Reich as part
