Counterattack also required time to prepare; decimated troops needed to be replaced and given rest, and strategic supplies needed time to be gathered and transported.
It had already been proven that modern warfare was no longer simply about combat on the battlefield; the rear areas were equally engaged in the fight.
The newly initiated Battle of Rhine is one such example; without Austria assembling a large number of machine guns and artillery, it would have been impossible to withstand the French Army's assault with inferior troop strength.
The stronger the artillery, the greater the logistical needs. Over eighty percent of the trains and ships heading from Austria to the frontlines were transporting strategic materials.
If not for the logistical supplies occupying a massive amount of transport capacity, the operations of the Austrian army would not have been so slow.
Of course, the current slowness was in preparation for future speed.
