A war cannot be easily instigated with a snap of the fingers or a wag of the tongue.
It requires the preparation of various aspects, such as the mobilization of troops and horses, accumulation of food and fodder, and the strategy of dispatching soldiers, before choosing the right timing and opportunity to launch the war according to the predetermined strategy.
For the upcoming Battle of Hanzhong, Lu Yuan was responsible for the mobilization of troops, deployment strategies, and other aspects.
As Chu State's highest military commander, he had to be involved in the approval and consent of the movement of troops within the country, both large and small.
Therefore, the decision on which army to dispatch for the conquest of Hanzhong could only be made by Lu Yuan.
First of all, the garrison troops originally stationed in Qianzhong County and Dongting County could not be mobilized.
