It means: originally, fighting put the army in a position where it can't retreat but die, so the soldiers will March forward bravely and win the battle. Metaphor is to cut off the retreat in advance before you can make up your mind to succeed.

"Rebirth after death" is not only the courage of justice, but also the passion for life. It is a kind of life wisdom, a kind of self-salvation, a firm belief in self, and the patience and perseverance needed in the process of redemption.

During the Western Han Dynasty, Liu Bang sent general Han Xin to attack Zhao, and Zhao Wangkai led 200,000 troops to meet at Jingxingkou. Chen Yu did not listen to the advice of Li Zuoche, the counselor, and launched a life-and-death struggle with Han Xin. Han Xin deliberately put himself to death, and then set up an array by the river. The soldiers in the last battle became more and more brave in the Vietnam War, and then sent troops to take Zhao's camp lightly, killing and taking Zhao Wangxie alive.
