QuoteReplyTopic: The Angle Bastion and Artillery Posted: 04-Jun-2006 at 16:12
When Medieval masonry fortifications became obsolete after the introduction of mobile, efficient artillery, military confrontations in Italy and Flanders (where Spanish Habsburgs and the French came into conflict) tended for about 50 years to be decided on the battlefield rather than in sieges. No one wanted to be bottled up inside fortifications that could not be depended upon. It was almost a sure defeat.
After long experimentation and at great expense, new designs of fortification began to be introduced. The idea of the "angle bastion" had been around since the later 15th century, but the costs of construction impeded the wide implementation of the new designs. Mostly the angle bastion was found in the most active theater of war, Italy. Hence the name given to the new system: "trace italien," or Italian plan.
Italian engineers and architects became expert at this new system and were in high demand as the 16th century progressed.
As artillery was the nemesis of the old masonry walls, four major features of the "trace" became common:
(1) The new fortifications had lower, wider peripheries, or "walls" made more of earth covered rubble that could absorb shot better than brick or stone.
(2) At selected points around the fortification or town, a structure (the Angle Bastion) was built to accomodate artillery that could fire back at the besieger. This forced them to begin any siege much further away, and made a siege much longer, more difficult and costly to conduct.
(3) The whole structure of the fortification was usually built quite low and surrounded by a wide, deep ditch to reduce its profile as a target for the besieging artillery. The height of defensive curtain walls was essentially preserved by sinking the whole thing into the ground with the deep ditch around it.
(4) From the angled bastions that were placed to mutually support each other with gunfire, wide fields of fire were maintained, without structures or trees, to exact the highest cost on any attacking force.
Because of the enormous cost of these fortifications, not that many were built before about 1530. The event that caught peoples' attention was the horrendous sack of the basically undefended city of Rome in 1527 by Emperor Charles V's unpaid landsknechts. Soon the new system was more common, and by the 1550s, many important and strategic towns had angle bastion defenses.
Rather than battles in the open field, sieges became more common as defenders had confidence in their costly fortifications with angle bastions and large numbers of guns in position.
In 1552, during later years of the Habsburg-Valois wars, Charles V failed to take the city of Metz with an enormous army and a long and unsuccessful siege of the city with its newer defenses.
This new type of military architecture turned artillery from purely offensive to also an important defensive weapon from 1500-the mid 16th century.
Let's discuss battles, sieges, campaigns and the further changes that all this caused in Europe, both in the art of war and in society.
This is an excellent topic. The study of military architecture and its accomodation of gunpowder weapons (defensively and offensively) is quite interesting. Here are some interesting sources I have looked at on the subject:
Simon Pepper and Nicholas Adams, Firearms and Fortifications: Military Architecture and Siege Warfare in Sixteenth Century Siena.
James D. Tracy, ed., City Walls: The Urban Enceinte in Global Perspective.
Christopher Duffy, Siege Warfare: The Fortress in the Early Modern World 1494-1660.

I saw a diagram of either an Italian or Spanish citadel (can't remember which one) that featured small disconnected casemates in front of the angle bastions on the walls. They were embedded in the ground and allowed arqubusiers to provide even more enfilading fire under cover. Some were even outfitted for the soldiers to use sakers and small caliber cannon in the casemates.
I have always wondered why (and lamented the fact that) the Byzantines did not pay what little funds they had left to have Italian engineers outfit the old Theodosian land walls with angle bastions and artillery towers. Perhaps the Ottomans would not have had so much success with their bombards if this had been done. However, I suppose that by 1453, gunpowder military architecture was still in its infancy and had not reached the sophistication it would have in the mid 16th century.
The later development of the star-shaped fortress pretty much rendered siege warfare all but useless. It turned into a waiting match where logistics and supplies meant everything to the parties involved. Early modern examples of this are found on Cyprus and in Venetian Greece, for example.
Does anyone know if the Chinese developed any gunpowder architecture independently of the Europeans? I know that the Mings were quite enterprising in their use of cannon and artillery; it would be interesting to see what they came up with, if anything.

I think that is correct, by that time, the field where the combat
Fortress vs Artillery was more fierce is France, where the english
couldn't stop the attack of the french artillery deployed in the
final years of the war (since 1440 more or less), very few time for
change the walls (and England was a superpower so...). Contrary, the
italian wars began in 1494 and finished about 1530, with the two main
opponents deploying many artillery.

According to Parker, they didn't need it, because the extreme thickness of chinese usual walls.
I have not seen such casemates, but there were casemates at the connecting angles where the bastion met the main curtain wall. There were embrasures there for cannon so that enfilading fire could be poured on troops approaching the curtain wall (if they made it that far).

By 'usual' do you mean the walls that the imperial Chinese government built? Or do you mean the repairs and rebuilding that was done specifically on the Great Wall in the later periods? Surely as artillery became more sophisticated, the Chinese innovated some to combat sieges by enemies with cannon. I have Parker's book and will have to read that section.

Yeah, the picture was quite interesting and the placement of the casemates made sense. They had 360 degrees of sight and could provide even more of a crossfire.

Parker was talking about the walls of the cities, of 9-10 metres of thickness. but i don't remember the book
We have noted the enormous costs of reconstructing fortifications, and of the increasing difficulty of besieging the new style of fortified places. Longer sieges; much larger armies to completely cut off the besieged place AND to fight off relieving armies. That costs money too; a lot of it.
How did this revolution in war (widespread, expensive gunpowder technology, costly new ways and means of waging war) affect government in the 16th century (and the 17th)?
In earlier times authorities managed their own estates; the prince or king managed his own estates, and they lived mostly within their means. Extraordinary needs for resources were few and manageable. When wars occurred, they often ran out of steam because one or more participants were financially exhausted.
It did not happen overnight, but in the early modern period, there was a change in that.
Anyone have any ideas as to what happened?
Any views on why it happened?
Opinions on results?
Basically, who paid for all this, and how was it paid for?

Although this is getting a bit out of my range in time period, I will take a crack at answering.
Heads of state began to value sophisticated artillery trains over noble cavalry. This did not render the armored knight useless, however, because we can see the improvements in plate armor in the 16th-17th centuries, and that the Spanish especially used lancers in their armies, even in the New World. However, Charles VIII's utilization of cannon mounted on carriages in his invasion of Italy set a trend that kings picked up on. Also, I would like to point out that artillery was used to devastating ends at the battle of Alcazarquivir in the late 1500s. The flower of Portuguese nobility (and many Spanish nobles) were slaughtered by the Moroccans' use of artillery in the field.

Hmm...I am sure the answer to this is quite complex. If I had to point to some sources and methods, New World precious metals and Italian bankers come to mind. The Spanish milked the mines at Potosi and financed a good deal of Charles V and Philip II's campaigns. Did the French bring a significant amount of wealth from their relationship with northern Indian tribes and their domination of the fur trade? Maybe this is another source. The influx of silver from the New World messed up the Ottoman economy and almost eliminated them from the Levantine economic network; this allowed the Italian maritime republics gain an even better foothold in the Eastern Mediterranean. So I am sure the spice trade contributed to Western European war chests.

If we talking about Spain, the men that paid that expensive revolution
was the worker class, includiying the burguesy and the peasants, mainly
small farmers.
The industrial and commercial sector of Spain was powerful at the
beginning of the XVI century, of course we can't underestimated the
fact that this sector was conservative and that they had an entire
continent for they products guaranted by the monopoly, but is more near
to the true that the burguesy didn't want repay the money in the own
sector because was always dangered by: goverment tax, silver competence
(why we produce when can buy?) so arrival of foreign products, unsafely
of the activity because government confiscations of capital and ships
plus the piracy. At the final of that century, the spanish burguesy
both industrial and commercial was retreating from productive works to
the country, buying lands and noble titles; the foreign powers
increased their advance in those sector greatly, to a point where they
were more importants than the own spanish. This was a serious problem
for the state's finaces.
The agriculture: it is undisputable that the "pecheros" (man that pay
tax) specially in rural lands fall between 1500 and 1600; there were
very less farmers at the second time than the first and the productive
lands fall too. That is: the peasants was horriblely crushed by tax
that the cities couldn't pay while the century advance, many of they
migrated to America and others to the cities where a miserable class
grow, many more fall in a new serfdom (the serfdom advanced in Spain
since 1570 to 1700) with the ancient noblement but too with the new
noblemen from the city, a great mass of workers at partial time (i
don't know the correct english expression) born in the country; richest
lands weren't worked because the competence of foreign products paided
with silver or were destroyed directly when the wars of Las Alpujarras
and the expulsion of the "moriscos"; finally the food production
decline. Between 1590 and 1650 horrible plagues killed many of this
poor people and after the fall of cities's prosperity the country
failed to the state in the war effort, this plus the decrease of the
american mine production...
If we think following a logic, the state (and the military revolution,
the world expansion...) killed the vitality of Spain, and the glory was
in fact the misfortune of the nation.
I understand your point in regard to Spain. The royal decrees of bankruptcy from the later 16th century had delayed effects on the fiscal health of the entire monarchy (Brussels, Naples, etc.). Debts owed by the king to lenders, and not just bankers, were being repaid in bonds and in spread out annuities that approached 10% in interest at times. Grandees and hidalgos had been 'guilted' by the royal authority into contributions and loans.
Why work hard or expose yourself to military dangers if you can live off your annuities at home? By the 17th century, there was less and less interest in military service and in investing in the monarchy. The only one left with the old spirit was Olivares.

The spice trade of the East Indies benefitted the Portuguese merchants and the nobles who invested capital or effort in the spice trade. The Spanish hidalgos, and the king, realized wealth from the precious metals of the Americas as a byproduct of their failed voyages to Asia. Not until much later than 1500 did Spain (1580s) or the Dutch (after 1600) make much out of the trade of the East Indies.
How much the spice trade affected war chests is a questionmark. Portugal needed only her ships, sailors and small groups of soldiers to secure her route to wealth in the East. the Habsburgs of Spain, with all their lands, titles and responsibilities needed vast sums to finance such lofty responsibilities as upholding the Catholic faith, stemming the Turkish advance in the Mediterranean and colonizing South America.
When you think about it, Spain seems to have been overextended from the git-go. A land dependant on wealth from the Netherlands, from Italy and from a continent 3 or 4,000, or more, miles away was certainly at a disadvantage in relation to a populous, wealthy country like France or the Ottoman Empire. It makes their achievement all the more amazing. (Portugal too...very small population; enormous distances to the East, and established, rich cultures she had to contend with and defeat. Remarkable.)
