2. To engage in battle only when victory can be assured by other
advantages in Strategetic means, which nullify the adverse
advantage in Numbers; and even then only when such victory is
decisive of the Campaign.
Hence, the policy of Campaign of that army superior in Numbers, is:
Incessantly to proffer battles which:
(a) Accepted, constantly reduces the inferior army and increases
its disproportion in numbers, or,
(b) Evaded, compels the inferior army to abandon important posts,
for whose defence it cannot afford the resulting loss of troops;
thus permitting to the numerically superior army a continually
increasing advantage in Position.
