Like his brothers, Folard was educated by the
Jesuits but ran away to join the
French Royal Army at the age of 16, an action allegedly inspired by reading
Caesar's "Commentaries". Forced to return home after his father wrote to his commanding officer, in 1687 he was allowed to join the
Régiment de Béarn as an
Officer cadet. Promoted
Second lieutenant on the outbreak of the
Nine Years War in 1688, his unit spent most of the war on garrison duty and when
peace came in 1697, Folard was an obscure
lieutenant.
War of the Spanish Succession 1705; badly wounded in the battle, his experience there shaped many of Folard's ideas on offensive tactics The
War of the Spanish Succession began in July 1701, and in early 1702 Folard's regiment was sent to secure
Naples, where he spent most of the next three years. He used the time to produce a series of tactical ideas and suggestions that brought him to the attention of the
duc de Vendôme, commander of the French forces in Italy. Despite this, promotion remained slow, allegedly because Folard was unpopular with his superiors. In October 1703,
Savoy joined the anti-French
Grand Alliance. During 1704, Folard served in
Lombardy under Vendôme's less talented brother,
Philippe de Vendôme, also known as the "Grand Prior". The campaign largely consisted of siege and positional warfare, which allowed Folard to display his engineering skills, and by the end of 1704 he was acting as technical advisor to the Grand Prior. Wounded at
Cassano in August 1705, he was awarded the
Cross of St. Louis in recognition of his service. While recuperating, Folard began developing the ideas on
columns that formed the basis of his intellectual effort from then on. He recovered in time for the 1706 campaign, and was appointed deputy to the commander of the French garrison in
Modena. Defeat at
Ramillies in July forced
Louis XIV to withdraw many of his forces from Italy, while the breaking of the
Siege of Turin left Modena isolated and it surrendered in February 1707 after a siege of four months. In March 1707, the
Convention of Milan provided the remaining French troops in Italy free passage to France, rather than being held as
prisoners of war. Folard was among those who were transferred to
Flanders, where he served under Vendôme during the 1708 campaign, although he did not participate in any major action. Badly wounded once again at
Malplaquet in 1709 and with the war largely at a stalemate from 1710, Folard continued to bombard his superiors with ideas and suggestions. In 1711, he was made military Governor of
Bourbourg, but lost this position following the 1713
Peace of Utrecht.
Later career , whom Folard viewed as the most talented general of the period In 1714, he joined a group of French officers and engineers sent to support the
Knights Hospitallers, who feared their base in
Malta was threatened by the
Ottoman–Venetian War. Instead, the Ottomans attacked
Venetian possessions in
Greece and after falling out with his colleagues, Folard returned to France in 1715. Sponsored by
Georg Heinrich von Görtz, in 1716 he entered the service of
Charles XII of Sweden, then engaged in the latter stages of the
Great Northern War, and whom Folard considered the most talented general of his time. While in
Stockholm, he set out his tactical ideas in the form of a commentary on the works of the Greek historian
Polybius; he left Sweden on the grounds of ill-health in November 1717 and was shipwrecked on the voyage home, losing all his papers and baggage. During the
War of the Quadruple Alliance, Folard served under the
Duke of Berwick at the
Siege of San Sebastián in 1719 and was finally promoted to
colonel. However, his habit of arguing with his superiors resurfaced and he wrote to the Minister of War criticising Berwick, whom he regarded as excessively cautious. With Europe finally at peace, this was the end of his active military career.
Retirement Folard spent the next decade preparing his commentaries on Polybius, which were published in 1724 and 1729 respectively. By analysing the battles described by Polybius and adding his own insights, he sought to identify a consistent set of military principles, which included both tactics and leadership. Although some were supported by an influential minority, his contemporaries were largely unconvinced and Folard spent much of his time refuting their criticisms. After Folard's death in 1753,
Frederick the Great produced a handbook or "Extract" based on his work; this excluded his ideas on columns and primarily contains Folard's account of Cassano and his claim that it proved the offensive power of the
bayonet; it was this aspect that made it attractive to Frederick, who wanted to install aggressiveness into his officer corps. During the early 1730s, Folard became involved with the Catholic theological movement known as
Jansenism, in particular the faction known as
Convulsionnaires. Declared
heretical by the Catholic church and viewed with suspicion by the French state, his biographer suggests Folard's involvement was driven not by depth of religious feeling but antipathy towards
Cardinal de Fleury, the government chief minister who was a leading opponent of Jansenism and had rejected his pleas for an increased pension. Folard was elected a
Fellow of the Royal Society of London in 1750 and died on 23 March 1752 in Avignon, where a number of public buildings and streets are named after him, including the
Piscine Chevalier de Folard. ==Military theories==
