Part of it was Napoleon’s dedication to discipline and hard work. He was very organized. Napoleon was careful to search for the wounded after battles and he would make every effort to make them feel special and rewarded. Napoleon really did make every effort to stop the wars, apart from giving everything to the allies and giving up until he did do these things. He could have continued fighting and many were urging him to but Napoleon did stop on his own.
In other words, most of Napoleon’s soldiers understood the real situation between him and his enemies and they wanted to help their hero. Napoleon was fighting a war of extermination and they were willing to stand up for their side even if that meant dying for their beliefs.
Throughout the memoirs below, we see in a thousand little ways how deeply Napoleon loved his soldiers and they returned that love - for the most part.
