古时候打仗,主力部队往往不会倾巢而出,尤其是步兵,不像如今的影视剧中演的那样,在集结几万人后,排着方队浩浩荡荡一起出发,而是分阶段地、一拨一拨地出发。各地的后续援军也是先从四面八方奔向集结地,合流之后再一拨一拨地出发。只有骑兵可以迅速集结,然后成建制地快速奔袭。但骑兵的培养和运营成本太高了,国家养不起那么多的骑兵。所以就会出现一个奇怪的现象:双方军队明明已经遭遇了,但大家都不会一碰面就 In ancient times, the main force often did not stand out, especially the infantry, unlike the current film and television drama, as tens of thousands of people in the assembly, the mighty team row together starting, but in stages , Set aside a wave of departure. Follow-up reinforcements around the country are also starting from all directions to the assembly area, after the confluence of another set aside to start. Only cavalry can quickly assemble, and then quickly established as a raid. However, the cost of training and operating cavalry is too high for the country to support so many cavalry soldiers. So there will be a strange phenomenon: the two sides obviously have encountered the army, but we will not meet each other
