In "The Guns of August," Barbara W. Tuchman discusses the prevailing military attitude that regarded reserve forces with disdain. This viewpoint was influenced by a new strategy focused on the offensive, which proponents believed could only be effectively taught to active soldiers. The ability to execute a strong, impetuous attack, exemplified by the famed bayonet charge, was thought to depend on the spiritedness and commitment of the troops. Those who were accustomed to civilian life while managing familial duties were deemed incapable of this essential military élan.

The mixing of reserve and active soldiers was seen as detrimental, leading to what some feared would be "armies of decadence." Such a blend was considered likely to weaken the fighting spirit necessary for decisive victories. The belief was that only soldiers fully immersed in military life could embody the vitality and determination required for a successful offensive, thus reinforcing the belief that effective armies must be solely composed of active, engaged troops.
