What members of this group were too exhausted to continue war?

It seems you're referring to a specific group, but without additional context, it's difficult to provide a precise answer. Generally, in various historical conflicts, soldiers or factions within an army may become too exhausted to continue fighting due to prolonged combat, lack of resources, or morale issues. For example, during World War I, many soldiers on both sides experienced severe fatigue and mental strain, leading to a breakdown in their ability to continue the war. If you provide more context about the specific group or conflict, I can offer a more targeted response.
