“In military parlance, that’s known as a Zangenangriff (i.e., “pincer movement” in English). According to von Clausewitz, it is intended to confuse and bewilder the Enemy and to probe for weakness in his defenses.”
Only if it’s planned strategically. Military commanders ordering the shots. That’s not what’s happening here.
I know; my comment was nevertheless intended to remind us all that this is not a mere "caravan," but rather an invasion.
There are similarities and parallels, after all.
And even the barbarian invaders (Visigoths, etc.) tended to attack from more than one direction.
Even wolves are smart enough to not employ a full frontal assault.
