The Silver Sword is a classic piece of children's literature written by Ian Serraillier, first published in the UK in 1956 by Jonathan Cape and then by Puffin Books in 1960. It has also been published in the U.S. under the title Escape From Warsaw. The story is based upon fact, although imaginary names are given to a few of the places mentioned. An eight-part children's television series was produced by the BBC in 1957 at the Lime Grove Studios in London. In a later edition of The Silver Sword, the book was published with a summary. Joseph Balicki, the head teacher of a school in Warsaw, was arrested by the Gestapo in early 1940 and taken away to a prison camp. His school had been taken over by the Nazis after the invasion of Poland and he was forced to teach lessons entirely in German.
