There are many examples of Napoleon: Napoleon hesitated in the battle when he decided to divide his forces and pursue blucher, the remnants of Prussia. Finally, this mistake became a turning point in the battle.

2. In the Battle of Borodino, he hesitated about the decision to invest in the support of the old guards, and finally failed to hit the main force of the Russian army.

3. At the gates of Moscow, he made a decisive choice in retreat and pursuit, and finally retreated in the severe winter and was completely annihilated.

Napoleon's most powerful enemy, Archduke Karl, also made a mistake: he didn't feel that the French army had just crossed the river and the formation was unstable, so he launched a siege and delayed the fighters, and finally failed to achieve results.

Hitler: Not only in Dunkirk, but also when he sent troops to Western Europe, he felt incredible and unsure of the rapid attack of the German army many times, and repeatedly asked the army to stop attacking.

Rommel: At first, I had a correct judgment about the landing point of the allied forces, but I was not confident enough and eventually failed irretrievably.

The Russian army in the Russo-Japanese War: It is stronger than the Japanese army in strength and military thought, but it is indecisive and hesitant to defend or not defend big cities such as Fengtian. They are often surrounded by fewer troops and lose the war in vain with superior troops.
