From publisher: This book "is a light, easy reading book containing many examples of early cryptographic systems. Chapters include: The American Systems in the Revolutionary Period; The British Systems in the Revolution; The Federal Systems in the Civil War; The Confederate Systems in the Civil War; A Diplomatic System in the Civil War Period; Cryptographic Progress 1865-1917." Petersen notes that this was "[p]repared after World War II." Constantinides comments on the "shallow quality" of the study, even given that certain material was not available.

Constantinides: This work reads just like the form in which it began life: "a typical government orientation lecture." It gives bare-bones treatment of the various names, organizations, and reorganizations over a period of thirty years and two wars.
