when the proper moment has arrived for launching the reserves. It is only necessary to recall the premature advance of the artillery and cavalry over the ravine of the Mance brook, on August 18th, 1870.
The cessation of the defender's fire, in itself, is not a sure sign that his firing line is shaken, as the attacker is unable to distinguish between a fire pause ordered by the commander on the defensive and the forced discontinuance of the fight. Sure indications are not available until men actually leave the defender's fighting line here and there, and attempts of the leaders to hold the wavering ones are clearly apparent.
At this moment, a leader who has resolved to assault, should order bayonets fixed.
The temporary interruption of the fire occasioned by fixing bayonets is of no importance, as the superiority of fire has already been gained. If bayonets are prematurely ordered to be fixed, the accuracy of the fire will soon be impaired, as the firing of rifles, weighted down by the attached bayonets, increases the fatigue of the men. When the troops are excited, the downward deflection of the bullets caused by fixing the bayonet can, however, only produce a good effect. It is best to fix bayonets at the signal "Fix bayonet". In the excitement prevailing at the moment, it will be impossible to execute the order with any uniformity, but it is a good plan, in time of peace, to require one man of each file to fire while the other one fixes his bayonet. The approaching reserves fix bayonets while on the march.
