X-WR-CALDESC:On 3 August 1918\, the 'Mohawk' field code was issued. Learn a
 bout American Army Field Codes in a document by William Friedman via the l
 ink at the bottom of the page.\n\nTrench codes were codes used for secrecy
  by field armies in World War I. A reasonably-designed code is generally m
 ore difficult to crack than a classical cipher\, but of course suffers fro
 m the difficulty of preparing\, distributing\, and protecting codebooks. T
 he Americans adopted a series of codes named after rivers\, beginning with
  'Potomac'. They learned to print the codebooks on paper that burned easil
 y and degraded quickly after a few weeks\, when the codes would presumably
  be obsolete\, while using a font that was easy to read under trench condi
 tions.
