But to the Allied troops listening in -- and they were always listening -- the crucial messages sounded like gibberish. The communications were encoded with a powerful cipher, making all information utterly inaccessible unless you could unlock the key to the secret code behind the German's powerful Enigma machine. This tells the true story of one of the most dangerous war-time code-breaking efforts ever. While Hitler marched his troops across newly conquered lands and deadly "wolfpacks" of German U-Boats prowled the open seas, a team of code-breakers, spies, and navy men raced against the clock to uncover the secrets that hid German messages in plain sight. Victory -- or defeat -- in World War II would hinge on their desperate attempts to crack the code. 521 1 $a Ages 10-14. 650 0 $a World War, 1939-1945 $v Juvenile literature. 650 0 $a Cryptography $v Juvenile literature. 650 0 $a Cryptographers $v Juvenile literature. 650 0 $a Enigma cipher system $v Juvenile literature. 655 7 $a Children's audiobooks. $2 lcgft 700 1 $a Bennett, Erin, $e narrator. 941 $a 1 945 $a cdab 952 $l S1PD771 $d 20221102013308.0 956 $a http://locator.silo.lib.ia.us/search.cgi?index_0=id&term_0=274B3FC05A7611ED87E8DDB93EECA4DBInitiate Another SILO Locator Search
