The authors emphasize a crucial principle in warfare through their Seventh Commandment, asserting that battles fundamentally revolve around morale. The moment hope fades, defeat becomes unavoidable, highlighting the importance of mental resilience in conflict situations. This concept illustrates that victory is determined not merely by the amount of suffering endured, but rather by the strength of one’s will and the robustness of their spirit.

This perspective underscores how psychological factors can be just as vital as physical resources in determining the outcome of a battle. In essence, it conveys that while external circumstances may influence the battlefield, the true determinant of success lies in the unwavering resolve of individuals and their collective morale. This understanding of warfare encourages a focus on the inner strength required to persevere, making it a significant theme in Tuchman’s analysis.
