ABSTRACT
The secret of effective defence lies in depth. By depth and by the fullest exploitation of the ground and by camouflage, the defence becomes invisible. In this way … an attack … can be met with continual surprises … And the aim of this defence is to be ready at all times to meet any enemy thrust, any shift of his thrust point [Schwerpunkt], not by opposing it frontally by a line but by swallowing up … the attack.
