NOTE.
In the campaign of 1757, Frederick, marching to the conquest of Bohemia with two armies, which had each their separate line of operation, succeeded, notwithstanding, in uniting them in sight of the Duke of Lorraine, who covered Prague with the imperial army; but his example should not be followed. The success of this march depended entirely on the inaction of the duke, who, at the head of seventy thousand men, did nothing to prevent the junction of the two Prussian armies.
MAXIM V.
All wars should be governed by certain principles, for every war should have a definite object, and be conducted according to the rules of art. (A war should only be undertaken with forces proportioned to the obstacles to be overcome.)
