Penetration

Definition and stakes

Henry James,  The American scene (1907)

“ This further and further unchallenged penetration begets in the perverted person I speak of a really romantic thrill: it is like some assault of the dim seraglio, with the guards bribed, the eunuchs drugged and one’s life carried in one’s hand. The only drawback to such freedom is that penetralia it is so easy to penetrate fail a little of a due impressiveness, and that if stationed sentinels are bad for the temper of the freeman they are good for the “prestige” of the building. ”

“ Under other conditions, the objective will be subject to further limitations, as the defensive position will be organised in great depth, and while effective penetration will thus be more difficult to achieve it must, of necessity, be accompanied by widening in proportion to its depth in order that space for manoeuvre and facility for communication may be secured. ”

“ From a military point of view the penetration of a line of defence does not simply mean passing straight through it, but cutting it in half, and then by moving outwards as well as forwards to push back and envelop the flanks thus created and so widen the base of operation to admit the movement forwards of reserves and supplies, and the movement backwards of casualties and tired troops. ”
