It contains a fictional account of the [[children's crusade]] of 1212, as witnessed by Rudolf Hefting, a boy from the 20th century. The original [[Dutch language|Dutch]] title is ''Kruistocht in spijkerbroek''. ==Plot summary== Rudolf "Dolf" Hefting is a sixteen year-old who volunteers for an experiment with a [[Time travel|time machine]]. The experiment goes well, but through an accident Dolf is stranded in the 13th century. He saves the life of [[Leonardo Fibonacci]], without realizing who he is, and teaches him [[Arabic numerals]]. Together they join the German [[Children's Crusade]], and through his modern-day knowledge, Rudolph manages to save a lot of children from horrible fates. However, his knowledge also leads to accusations of [[witchcraft]]. In the book, two slavers delude a group of children into coming with them with stories of how the innocent shall liberate [[Jerusalem]]. Their actual intent is to sell them for profit. With the aid of his twentieth-century knowledge and skepticism, and the aid of a "magical" device or two (such as a box of matches), the boy manages to keep most of the children alive and eventually gets them to safety. ==Awards and nominations== The book won a [[Gouden Griffel]] and the European prize for best historical youth book in 1974, and the Prix de la Divulgation historique in 1976. ==Film, TV or theatrical adaptations== A [[Crusade in Jeans (film)|movie version]] directed by Ben Sombogaart went into production in 2005. The film was released in Belgium and the Netherlands on November 15th, 2006. Other regions will follow later in 2006.
