. Perhaps the most enduring aspect of Vauban's legacy was his view of France as a geographical entity. His advocacy of giving up territory for a more coherent and defensible border was unusual for the period; the boundaries of the French state he proposed in the north and east have changed very little in the four centuries since.

. His parents, Urbain Le Prestre ( 1602–1652) and Edmée de Cormignolle (died c. 1651), were members of the minor nobility, from Vauban in Bazoches. In 1570, his grandfather Jacques Le Prestre acquired Château de Bazoches, when he married Françoise de la Perrière, an illegitimate daughter of the Comte de Bazoches, who died intestate. The 30-year legal battle by the Le Prestre family to retain the property proved financially ruinous, forcing Urbain to become a forestry worker. He also designed gardens for the local gentry, including the owners of the Château de Ruère, where Vauban spent his early years. His only sister, Charlotte (1638–1645?), died young, but he had many relatives; his cousin, Paul le Prestre (c. 1630 – 1703), was an army officer who supervised construction of Les Invalides. Three of Paul's sons served in the army, two of whom were killed in action in 1676 and 1677. The third, Antoine (1654–1731), became Vauban's assistant and later a lieutenant-general; in 1710, he was appointed Governor of Béthune for life, while he inherited Vauban's titles and the bulk of his lands. Vauban's family was impacted by the domestic conflict and foreign wars, including the Huguenot rebellions of the 1620s, the 1635–1659 Franco-Spanish War, and 1648 to 1653 Fronde; his Catholic grandfather married a Protestant from

Career

In 1643, at the age of ten, Vauban was sent to the Carmelite college in Semur-en-Auxois, where he was taught the basics of mathematics, science and geometry. His father's work was also relevant; the design of neo-classical gardens and fortifications were closely linked, since they both concerned managing space. It was common to combine these skills; John Armstrong (1674–1742), Marlborough's chief military engineer, laid out the lake and gardens at Blenheim Palace. In 1650, Vauban joined the household of his local magnate, the Prince de Condé, where he met de Montal; a close neighbour from

, marking the end of his military career, although the ''Ceinture de fer'' proved its worth after the French defeat at Ramillies in 1706. Under pressure from superior forces on multiple fronts, France's northern border remained largely intact despite repeated efforts to break it. Capturing Lille cost the Allies 12,000 casualties and most of the 1708 campaigning season; the lack of progress between 1706 and 1712 enabled Louis to reach an acceptable deal at Utrecht in 1713, as opposed to the humiliating terms presented in 1707. With more leisure time, Vauban developed a broader view of his role. His fortifications were designed for mutual support, so they required connecting roads, bridges and canals; garrisons needed to be fed, so he prepared maps showing the location of forges, forests and farms. Since these had to be paid for, he developed an interest in tax policy, and in 1707 published ''La Dîme royale'', documenting the economic misery of the lower classes. His solution was a flat 10% tax on all agricultural and industrial output, and eliminating the exemptions which meant most of the nobility and clergy paid nothing. Although confiscated and destroyed by royal decree, the use of statistics to support his arguments "... establishes him as a founder of modern economics, and precursor of the Enlightenment's socially concerned intellectuals." In the course of his career, Vauban supervised or designed the building of more than 300 separate fortifications, and by his own estimate, supervised more than 40 sieges from 1653 to 1697.

Personal life and death

In 1660, Vauban married Jeanne d'Aunay d'Epiry (ca 1640–1705); they had two daughters, Charlotte (1661–1709) and Jeanne Françoise (1678–1713), as well as a short-lived infant son. He also had a long-term relationship with Marie-Antoinette de Puy-Montbrun, daughter of an exiled

Doctrines and legacy

Offensive doctrines; siege warfare

While his modern fame rests on the fortifications he built, Vauban's greatest innovations were in offensive operations, an approach he summarised as 'More powder, less blood.' Initially reliant on existing concepts, he later adapted these on lines set out in his memorandum of March 1672, ''Mémoire pour servir à l'instruction dans la conduite des sièges''. In this period, sieges became the dominant form of warfare; during the 1672–1678

, of which only Seneffe was unrelated to a siege. Their importance was heightened by Louis XIV, who viewed them as low-risk opportunities for demonstrating his military skill and increasing his prestige; he was present at 20 of those conducted by Vauban. The 'siege parallel' had been in development since the mid-16th century but Vauban brought the idea to practical fulfilment at

in 1673. Three parallel trenches were dug in front of the walls, the earth thus excavated being used to create embankments screening the attackers from defensive fire, while bringing them as close to the assault point as possible (see diagram). Artillery was moved into the trenches, allowing them to target the base of the walls at close range, with the defenders unable to depress their own guns enough to counter this; once a breach had been made, it was then stormed. This approach was used in offensive operations well into the 20th century. However, Vauban adapted his approach to the situation, and did not use the siege parallel again until Valenciennes in 1677. Always willing to challenge accepted norms, at Valenciennes, he proposed assaulting the breach during the day, rather than at night as was normal practice. He argued this would reduce casualties by surprising the defenders, and allow better co-ordination among the assault force; he was supported by Louis, and the attack proved successful. Vauban made several innovations in the use of siege artillery, including ricochet firing, and concentrating on specific parts of the fortifications, rather than targeting multiple targets. His Dutch rival Menno van Coehoorn employed a similar approach. While the 'Van Coehoorn method' sought to overwhelm defences with massive firepower, such as the Grand Battery of 200 guns at Namur in 1695, Vauban preferred a more gradual approach. Both had their supporters; Vauban argued his was less costly in terms of casualties, but it took more time, an important consideration in an age when far more soldiers died from disease than in combat.

Defensive doctrines; fortifications

It was accepted even the strongest fortifications would fall, given time; the process was so well understood by the 1690s, betting on the length of a siege became a popular craze. As few states could afford large standing armies, defenders needed time to mobilise; to provide this, fortresses were designed to absorb the attackers' energies, similar to the use of crumple zones in modern cars. The French defence of Namur in 1695 showed "how one could effectively win a campaign, by losing a fortress, but exhausting the besiegers." As with the siege parallel, the strength of Vauban's defensive designs was his ability to synthesise and adapt the work of others to create a more powerful whole. His first works used the 'star-shape' or

design, also known as the ''trace Italienne'', based on the designs of Antoine de Ville (1596–1656) and Blaise Pagan (1603–1665). His subsequent 'systems' strengthened their internal works with the addition of casemated shoulders and flanks. The principles of Vauban's 'second system' were set out in the 1683 work ''Le Directeur-Général des fortifications,'' and used at

; this allowed Vauban to combine his defensive principles with town planning, although like Mont-Royal, little of it remains. The French retreat from the Rhine after 1697 required new fortresses; Neuf-Brisach was the most significant, designed on Vauban's 'third system', and completed after his death by Louis de Cormontaigne. Using ideas from Fort-Louis, this incorporated a regular square grid street pattern inside an octagonal fortification; tenement blocks were built inside each curtain wall, strengthening the defensive walls and shielding more expensive houses from cannon fire. To create a more coherent border, Vauban advocated destroying poor fortifications, and relinquishing territory that was hard to defend. In December 1672, he wrote to Louvois: "I am not for the greater number of places, we already have too many, and please God we had half of that, but all in good condition!" Many of the fortifications designed by Vauban are still standing; in 2008, twelve groups of Vauban fortifications were inscribed on the

Infrastructure and engineering

While often overlooked, Vauban worked on many civilian infrastructure projects, including rebuilding the ports of Brest, Dunkerque and

. As early as 1684, Vauban published design tables for retaining walls with heights of 3 m < H < 25 m. Three years later, Vauban, in his role as newly appointed Commissary General of all French fortifications, sent his engineers in the Corps du Génie Militaire his Profil général pour les murs de soutènement in which he presented his retaining wall profiles that were later adopted by engineering offers such as Bélidor (1729), Poncelet (1840) and Wheeler (1870). He also provided advice on the repair and enlargement of the Canal du Midi in 1686. His holistic approach to urban planning, which integrated city defences with layout and infrastructure, is most obvious at Neuf-Brisach. His legacy is recognised in the Vauban district in Freiburg, developed as a model for sustainable neighbourhoods post-1998. Vauban's 'scientific approach' and focus on large infrastructure projects strongly influenced American military and civil engineering and inspired the creation of the

in 1824. Until 1866, West Point's curriculum was modelled on that of the French Ecole Polytechnique, and designed to produce officers with skills in engineering and mathematics. To ensure a steady supply of skilled engineers, in 1690 Vauban established the ''Corps royal des ingénieurs militaires''; until his death, candidates had to pass an examination administered by Vauban himself. Young French Huguenots made up a disproportionately high number of successful engineers due to the social and educational characteristics of French Protestantism. After the Revocation of the Edict of Nantes in 1685, a significant number of these engineers joined the English and Dutch armies to fight in Ireland, Flanders and Spain. Many of his publications, including ''Traité de l'attaque des places'' and ''Traité des mines'', were written at the end of his career to provide a training curriculum for his successors.

Assessment

Vauban's offensive tactics remained relevant for centuries; his principles were clearly identifiable in those used by the

at Dien Bien Phu in 1954. His defensive fortifications dated far more quickly, partly due to the enormous investment required; Vauban himself estimated that in 1678, 1694 and 1705, between 40 and 45% of the French army was assigned to garrison duty. Vauban's reputation meant his designs remained in use long after developments in artillery made them obsolete, for example the Dutch fort of Bourtange, built in 1742. The ''Corps des ingénieurs militaires'' was based on his teachings; between 1699 and 1743, only 631 new candidates were accepted, the vast majority relatives of existing or former members. As a result, French military engineering became ultra-conservative, while many 'new' works used his designs, or professed to do so, such as those built by Louis de Cortmontaigne at

Some French engineers continued to be innovators, notably the Marquis de Montalembert, who published ''La Fortification perpendiculaire'' in 1776. A rejection of the principles advocated by Vauban and his successors, his ideas became the prevailing orthodoxy in much of Europe, but were dismissed in France.
