the Nazis had been killing individuals with mental disabilities for years by their eugenics policies. Ten Boom defended her work by saying that in the eyes of God, a mentally disabled person might be more valuable "than a watchmaker. Or a lieutenant." Corrie and Betsie were sent from Scheveningen to Herzogenbusch, a political concentration camp (also known as Kamp Vught), and finally to the Ravensbrück concentration camp, a women's labor camp in Germany. There, they held worship services after the hard days at work by using a Bible that they had managed to smuggle in. Through the two sisters’ teachings and examples of unfailing charity, many of the prisoners there converted to Christianity. While they were imprisoned at Ravensbruck, Betsie and her sister began to discuss plans for founding a place of healing after the war. Betsie's health continued to deteriorate, and she died on 16 December 1944 at the age of 59. Before she died, she told Corrie, "There is no pit so deep that He [God] is not deeper still." Twelve days later, Corrie was released. Afterward, she was told that her release was because of a clerical error and that a week later, all the women in her age group were sent to the gas chambers. Ten Boom returned home amid the "hunger winter". She still opened her doors to people with disabilities who were in hiding for fear of execution. Life after the war After the war, Ten Boom returned to the Netherlands to set up a rehabilitation center in Bloemendaal. The refuge housed concentration-camp survivors and until 1950 exclusively sheltered jobless Dutch who had collaborated with the Germans during the Occupation, after which it accepted anyone in need of care. She returned to Germany in 1946 and met with and forgave two Germans who had been employed at Ravensbrück, one of whom had been particularly cruel to Betsie. Ten Boom went on to travel the world as a public speaker, appearing in more than 60 countries. She wrote many books during this period. One of these books is titled Tramp for the Lord and was written in the late 1960s and early 1970s. Each chapter tells a short, different story about her world travels and sharing the gospel message in Africa, Europe, the Americas, Asia, and even in difficult-to-reach and dangerous countries such as Russia (then-USSR), Cuba, and China. It features photographs of Ten Boom
