Real Warfare Improved land warfare mechanics
I always wondered about the in eu, why the battles that were won were always won by an ugly ratio of losses, close to one to one, and I won every time, but the number of dead men was not much less than the opposite side. Thus the battle of eu a game of constantly changing manpower with the opposite side, wave after wave. And after I looked into it, I discovered a shocking and bullshit fact.
As pictured, my French 17k unit took on the Portuguese 15k. The battle was fought on the 4th of June. And on the 8th of June, a group of cavalry on the opposite side of the field had been charged by my troops to 0 morale, but he did not retreat! Instead, he stayed on the field and continued to attack my troops until the 16th of June when he retreated. And because his morale was at 0, my troops stopped attacking him and went to attack others, while he was still at half capacity! That means he became a zero morale, unattackable ghost and stayed on the field for another 8 days before he left!
After some research I found out that this is the reason for the eu retreat mechanic. You can't retreat within twelve days of starting a war, and surprisingly this rule works for individual units too! Because of this, many times troops that should have retreated become invincible ghosts on the field and continue to kill your troops! This is exactly why many times we feel that we are winning big, but the battle damage ratio is very bad, close to one to one.
After a period of debug, everything was fine and the troops were ready to retreat with morale at zero.
As in the picture, it is the same place and the same troops. You can see that the time for retreat has not yet arrived, but three groups of cavalry with zero morale have already withdrawn on the opposite side.
