Navajo History

By the time the United States joined the Second World War in 1941, the fight against Nazi and Axis powers had already been underway for two years. In order to win the war and protect its soldiers, the US Marines recruited 29 Navajo men to create a secret code that could be used to send military messages quickly and safely across battlefields. In this new book within the number one New York Times best-selling series, author James Buckley Jr. explains how these brave and intelligent men developed their amazing code.

This fascinating look at history's most mysterious messages is packed with puzzles to decode and ciphers that kids can use themselves. Here are the encrypted notes of Spartan warriors, the brilliant code-crackers of Elizabeth I, secret messages of the American Revolution, spy books of the Civil War, the famous Enigma Machine, and the Navajo code talkers. As computers change the way we communicate, codes today are more intriguing than ever. From invisible ink to the CIA, this exciting trip through history is a hands-on, interactive experience - so get cracking!
