The Face of Battle (1976) is in some ways an oddly titled book. The title implies there is a singular face to battle that the author, John Keegan, is going to discover (and indeed, to take his forward, that is certainly the question he looked to answer). But that plan doesn’t survive contact with the table of contents, which makes it quite clear that Keegan is going to present not one face of battle, but the faces of three different battles and they will look rather different. Rather than reinventing the wheel, I am going to follow Keegan’s examples to make my point here (although I should note that of course The Face of Battle is a book not without its flaws, as is true with any work of history).

Keegan’s first battle is Agincourt (1415). While famous for the place of the English longbow in it, at Agincourt the French advance (both mounted and dismounted) did reach the English lines; of this the sources for the battle are quite clear. And so the terror we are discussing is the terror of shock; not shock in the sense of a sudden shock or in the sense of a jolt of electricity, rather shock as the opposite of fire. Shock combat is the combat when two bodies of soldiers press into each other in mass hand-to-hand combat (which is, contrary to Hollywood, not so much a disorganized melee as a series of combats along the line of contact where the two formations meet). The advancing French had to will themselves forward into a terrifying shock encounter, while the English had to (like our hoplites above) hold themselves in place while watching the terrifying prospect of a shock engagement walk steadily towards them.

There is actually quite a bit of evidence that the terror of a shock engagement is something different from the other terrors of war (to be clear, not “better” or “worse”, merely different in important ways). There are numerous examples of units which could stand for extend periods under fire but which collapsed almost immediately at the potential of a shock engagement. To draw a much more recent example, at Bai Beche in 2001, a force of Taliban withstood two days of heavy bombing and had repulsed an infantry assault besides, but collapsed almost immediately when successfully surprised by a cavalry charge (yes, in 2001) in their rear (an incident noted in S. Biddle, “Afghanistan and the Future of Warfare”, Foreign Affairs 82.2 (2003)).

And so our sources for state-on-state pre-gunpowder warfare (which is where you tend to find more fully “shock” oriented combat systems) stress similar sequences of fear: the dread inspired by the sight of the enemy army drawing up before you (Greek literature is particularly replete with descriptions of teeth-chattering and trembling in those moments and it is not hard to imagine why), followed by the steady dread-anticipation as the armies advanced, each step bringing that moment of collision closer. Often in such engagements one side might break before contact as the fear not of what was happening, but what was about to happen built up. And only then the long anticipated not-so-sudden shock of the formations coming together – rarely for long given the overpowering human urge not to be near an enemy trying to stab you with a sharp stick. There is something, I think, quite fundamental in the human psyche that understands another human with a sharp point, or a huge horse rapidly closing on a deeper level than it understands bullets or arrows.

Which brings us to Keegan’s second battle, Waterloo (1815), defined in part by the ability of the British to manage to hold firm under extended fire from artillery and infantry. The French artillery in an 80-gun grand battery opened fire at 11:50am and kept it up for hours until the French cavalry advanced (hoping that the British troops were suitably “softened” by the guns to be dislodged) at 4pm. In contrast to Agincourt (or a hoplite battle) which may have ended in just a couple of hours and consisted mostly of grim anticipation, soldiers (on both sides) at Waterloo were forced to experience a rather different sort of terror: forced to stand in active harm for hours on end, as bullets and cannon shot whizzed overhead.

The difference of this is perhaps most clearly extreme if we move still forward to the Somme (1916) and bombardment. The British had prepared for their assault with a week long artillery barrage, in which British guns fired 1.5 million shells (that is about 148 shells fired a minute, every minute for a week). At the first sound of guns, soldiers (in this case, the Germans, but it had been the French’s turn just that February to be on the receiving end of a bombardment at Verdun) rushed into their dug-out bomb shelters at the base of their trench and then waited. Unlike the British at Waterloo, who might content themselves that, one way or another, the terror of fire would not last a day, the soldier of WWI had no way of knowing when the barrage would cease and the battle proper begin. Indeed, they could not see the battlefield at all, only sit under the ground as it shook around them and try to be ready, at any moment when the barrage stopped to rush back up to the lip of the trench to set up the machine guns – because if they were late to do it, they’d arrive to find British grenades and bayonets instead.

We will get into wounds, both physical and mental, next week, but it is striking to me that repeatedly there are reports after such barrages of soldiers so mentally broken by the strain of it that they wandered as if dazed or mindless, apparently driven mad by the bombardment. Reports of such immediate combat trauma are vanishingly rare in the pre-modern corpus (Hdt. 6.117 being the rare example). And it is not hard to see why the constant threat of sudden, unavoidable death hanging over you, day and night, for days or in some cases weeks on end produces a wholly different kind of terror.

And yet, to extend beyond Keegan’s three studies, in talking to contemporary veterans, it seems to me this terror of fire – being forced to stand (or hide) under long continuous fire – is not always quite the same as the terror of the modern battlefield. Of course I can only speak to this second hand (but what else can a historian generally do?), but there seems to be something different about a battlefield where everything might seem peaceful and fine and even a bit boring until suddenly the mortar siren sounds or a roadside IED goes off and the peril is immediate. The experience of such fear sometimes expresses itself in a sort of hypervigilance which seems entirely unknown to Greek or Roman writers (who in most cases could hardly have needed such vigilance; true surprise attacks were quite rare as it is extremely hard to sneak one entire army up on another) and doesn’t seem particularly prominent in the descriptions of “shell-shock” (which today we’d call PTSD) from the First World War, compared to the prominence of intense fatigue, the thousand-yard-stare and raw emotional exhaustion. I do wonder though if we might find something quite analogous looking into the trauma of having a village raided by surprise under the first system of war.
