Thus it is that while every Chesspiece represents a perfectly appointed and equally powerful body of troops, these corps d’armee in Chessplay as in scientific warfare are not duplicates, except to others of their own class. Each of these corps d’armee is made up of Infantry, Cavalry and Artillery in correct proportion to the service they are to perform and such proportions are determined not by simple arithmetic, but by those deployments, developments, evolutions, and manoeuvres, which such corps d’armee is constructed promptly and efficiently to execute.
The Chessmen, therefore, do not as individuals represent either infantry, cavalry or artillery.
But in the same manner as the movements of troops over the surface of the earth, exemplify the attributes of the three kindred grand columns in the greater logistics of a campaign; so do those peculiarities which appertain to the moves of the different Chesspieces exemplify the action of the three chief arms of the military service; either singly or in combination against given points in given times, in the evolutions of the battlefield, viz.:
