The March Forward
At Alexander common, the army slowly turned around to face the road, and filing themselves into a three columned line, with each soldier standing one to two meters apart, slowly started their march, their steps sure and heavy, as they made their way to wrought doom to the country of Tibias.
The entire procession stretched a few kilometers, and from the above, it looked like a giant ant trail.
At the very front of this procession, leading the pack so to speak was one part of the cavalry, which acted both a scout and a rapid reaction force if any unforeseen event were to occur.
Now, granted they were squarely in their own territory and there was no singular fool who would attack an army of 50,000 on his own.
But this was the military doctrine of the time and officers had to follow it, hence the specific order.
