I had formed the theory that the true rôle of the Infantry was not to expend itself upon heroic physical effort, nor to wither away under merciless machine-gun fire, nor to impale itself on hostile bayonets, nor to tear itself to pieces in hostile entanglements — (I am thinking of Pozières and Stormy Trench and Bullecourt, and other bloody fields) — but, on the contrary, to advance under the maximum possible protection of the maximum possible array of mechanical resources, in the form of guns, machine guns, tanks, mortars and aeroplanes; to advance with as little impediment as possible; to be relieved as far as possible of the obligation to fight their way forward; to march, resolutely, regardless of the din and tumult of battle, to the appointed goal; and there to hold and defend the territory gained; and to gather in the form of prisoners, guns and stores, the fruits of victory.

What It Means

This is a placeholder explanation generated by the low-overhead model. It interprets "I had formed the theory that the true rôle of the Infantry was not to expend itself upon heroic physical effort, nor to wither away under merciless machine-gun fire, nor to impale itself on hostile bayonets, nor to tear itself to pieces in hostile entanglements — (I am thinking of Pozières and Stormy Trench and Bullecourt, and other bloody fields) — but, on the contrary, to advance under the maximum possible protection of the maximum possible array of mechanical resources, in the form of guns, machine guns, tanks, mortars and aeroplanes; to advance with as little impediment as possible; to be relieved as far as possible of the obligation to fight their way forward; to march, resolutely, regardless of the din and tumult of battle, to the appointed goal; and there to hold and defend the territory gained; and to gather in the form of prisoners, guns and stores, the fruits of victory." in the context of "Ch. 5" to mean that wisdom is timeless.
