The recruit must be carefully and sedulously taught when meeting the enemy, even at a trot or canter, to use no force whatever, otherwise his sword will bury itself to the hilt, and the swordsman will either be dragged from his horse, or will be compelled to drop his weapon — if he can.The instructor must spare no pains in preventing the soldier from using force, especially with the left or guiding arm, as too much exertion generally causes the thrust to miss. A trifling body-stab with the bayonet (I may add with the sword) is sufficient to disable a man; and many a promising young soldier has lost his life by burying his weapon so deep in the enemy's breast that it could not be withdrawn quickly enough to be used against a second assailant. To prevent this happening, the point must be delivered smartly, with but little exertion of force, more like a dart than a thrust, and instantly afterwards the bayonet must be smartly withdrawn.
