Answer:
He put out expectations and gave the men self-value. He also put himself at risk of being killed.
Explanation:
At the siege of Toulon, when his artillery men were being bombarded hard by Allied troops, he renamed his battery, "The Battery of Men Without Fear." The n just like that, his men returned fighting with extra morale. Napoleon also charged and was stabbed at the battle of Toulon, nearly ending his life, but jaw-dropping morale boost for his men. In the campaigns of Italy, he was nearly cut down by cannon fire and was covered in mud at Arcole. It motivated his men to do an almost suicidal charge across the bridge, and they did win that battle, although taking heavy losses, they took 4000 men prisoner. Before the invasion of Italy happened, he motivated his men with speeches before they marched. These are just of Napoleon's examples of incerasing his men's morale, no wonder they would die for him, and stay loyal to him to the end. Except Bernadotte that traitor.
