Hi, I'm preparing for a Warring States TL, and I'd like to ask those more well versed in warring states history on the way that warfare was conducted at the time. I do know that warfare involved a long period of planning and facing off each other that could last years, but does anyone know of the details involved in these battles? Procedures? Customs? Praying to Heaven? How many battles would a war generally involve? If not, any useful sources that one could use? Any help would be very much appreciated.
