It is possible that I am simply
going to repeat myself, or at least state things which most people would say ‘Of
course’ to. On the other hand, sometimes stating the blinking obvious is a good
thing to do.
I suppose the first thing I want
to suggest is that things, generally, go in fashions. There might be, for
example, a fashion dressing your soldiers up in fancy red uniforms to march
into battle. There might not, in fact, be any particularly good or bad reason
for doing this. It might be that red is a martial colour in your culture, and
thus seems to be a good option for trying to instil some valour, ardour or some
such into the troops. Your enemy might have a different culture, wherein, say,
red is the colour of cowardice and blue is that of valour. They might, thus, be
very willing to attack your red clad troops, but flee from the odd blue
bedecked regiment of cavalry that you have permitted just for a spot of
variation.
Fashions, however, change. These changes
can be brought about by a variety of causes. For example, a fair bit of
European army kit changed when those armies were fighting in places that were
not Europe. Light infantry, irregulars, and different sorts of swords and so on
were all incorporated into military equipment and tactics as a result of
experience beyond the home shores of the culture. This is, of course, not unique. The Romans
pinched their sword from the Spanish, after all.
Fashions are more than simply in dress,
equipment or tactics. I have very briefly tried to suggest that ideas have an
impact on how warfare is conducted. The particular example I had in mind was
the ‘star’ fortress style, particularly associated with Vauban but used
extensively before then. The idea is of course usually explained fairly simply
as a response to the increased firepower of cannon in besieging armies. The instrumental
requirements of a form of fortification which could resist cannon fire more
effectively led designers to build lower walls, packed with earth, and with
open fields of fire. A round tower simply could not match the modern fortress
in ability to block the attackers and blunt their force.
Except, of course, that often old
style castles could, and did, resist modern siege weapons. One problem, at
least, facing would be besiegers, was that of actually getting the siege
weapons into place. This was a huge logistical problem. Once arrived, there was
the problem of siting the weapons so they could be effective and, of course, of
ensuring the supply of the besiegers, in terms of food, water, weapons and men.
A siege of even a simply medieval style castle was no joke, as some of the
problems encountered in the English Civil war demonstrate.
But another issue in the design
of castles must have been that of the intellectual changes brought about by the
renaissance. While medieval castle builders did, indeed, use mathematics to
calculate, for example, how many steps were needed in a spiral staircase, star
style fortresses needed some more advanced ideas about geometry. Indeed, if
these were not forthcoming, there arose some slightly odd shapes. For example,
the defences of Berwick on Tweed are irregular. This might be due to the lie of
the land, to the inadequacy of surveying or to someone who was a bit dangerous
to let loose with a compass and set square. Of course, one might suggest to Her
Majesty that that was how it was meant to be all along, and it is perhaps
fortunate that the defences were never seriously tested, but the idea was there
of something pleasingly geometric in shape, and that comes from the interest in
mathematics of the renaissance.
Of course, warfare is not the
only place where one sees this. Galileo was interested in geometry, and there
is evidence that his concepts were based on the idea of geometry. Spinoza, too,
thought geometrically, as least, insofar as his Ethics is written like a
geometry text book. Euclid was viewed as the ultimate in comprehensive proof,
and people attempted to emulate him. The idea of geometry, thus, permeates a
fair bit of intellectual culture in the sixteenth and seventeenth centuries,
and it would be a rash historian indeed who suggested that it did not affect
military theory and practice.
We can possibly push on a little
further with this notion. The military text books of the day were rather
obsessed with order and geometry, with nice diagrams explaining how to array a
certain number of men in blocks so many deep and thus how wide they should be.
Montecuccoli, for example, suggests an octagonal infantry battalion at one
point, for battalions at the ends of the battle line. This is a sophisticated
sort of formation, and it indicates, from the text, that he is interested in
geometry, and would seem to me to need seriously trained soldiers to carry it
out without getting into severe disarray.
The point is that Montecuccoli,
as a theoretician as well as a general, we thinking geometrically, as part of
the culture in which he was educated. To think geometrically is simply to be
part of the intellectual culture of the day. That is not to say it was used
uncritically, although that accusation could be aimed at some of the text
books. It was simply part of how things were thought about.
There were reverse influences, as
well. Asking a theoretician to design a fortress could have impact on the
development of mathematics, geometry and architecture. I seem to recall that Durer
was one such, although I think he pre-dated the star style fortress.
Nevertheless, he can be seen as a transitional figure, designing shorter, stubby
towers packed with earth to resist cannon fire, an idea taken up by Henry VIII
in the defence of English shores.
I was going to start talking about
the influence of ideas on tactics, such as the caracole, but I am starting to
think that this piece is both long enough and both arguable enough and not
radical enough, so I shall have to leave it there and return to the Curious
Case of the Caracole another time.
