Regarded as a Chessic Corps d’armee the Knight marches and attacks as
cavalry and artillery.
From one to four Knights may be present in any given Strategetic Horizon;
and whenever present the effect of its co-operation mathematically is
outlined, viz.:
At its maximum of efficiency, the Knight occupies the centre of an
octagon of two points radius, having a minimum of two points and a
maximum of eight points area. His offensive power is equally valid
against all of these eight points, but his defensive power is valid for
the support of only one point.
