The three rotor Enigma became the cryptologic workhorse of the German land forces before World War II and continued as such until V-E Day. Rugged, completely portable, and requiring no external power source, the machine was ideally suited to the highly mobile "lightening" type of war envisioned and practiced by the German High Command. Although a few German officers felt that Enigma could be broken by a determined cryptanalytic attack, the prevailing feeling was that the time needed by a cryptanalyst was so great that its value would be lost-no serious effort was made to determine otherwise.
