James FitzJames, 1st Duke of Berwick, 1st Duke of Liria and Jérica, 1st Duke of Fitz-James (21 August 1670 – 12 June 1734) was a French-English army officer who was the eldest illegitimate son of James II of England by Arabella Churchill, the sister of John Churchill, 1st Duke of Marlborough. Born and raised in France, Berwick was a senior Jacobite commander in his father's army during the Williamite War in Ireland. He subsequently became a successful general in the service of Louis XIV and in 1706 he was made a Marshal of France. Berwick was honored with noble titles from the kings of both France and Spain, in addition to his English ducal title which was attainted in 1695. He was decapitated by a cannonball during the Siege of Philippsburg in 1734.
FitzJames was born at Moulins in France before his father's accession to the throne, and was brought up in France as a Catholic. He was the son of James and his mistress Arabella Churchill, sister of the English captain general and statesman John Churchill, 1st Duke of Marlborough. He seems to have inherited or perfected the same military ability as his uncle, Marlborough. He was educated at the Stuarts' expense in the College of Juilly, the Collège du Plessis, and the Jesuit College of La Flèche. He went into the service of Charles V, Duke of Lorraine, and was present at the Siege of Buda (1686). FitzJames was created Duke of Berwick, Earl of Tinmouth and Baron Bosworth by his father in 1687. He then returned to Hungary and participated at the Battle of Mohács.
Berwick returned to England and was made Governor of Portsmouth. King James made him a Knight of the Order of the Garter and appointed him Colonel of The Blues to replace the Protestant Aubrey de Vere, 20th Earl of Oxford. The post had been coveted by his maternal uncle the Duke of Marlborough, but FitzJames was earmarked for command, as Catholics replaced Anglicans. However, due to the invasion of the Prince of Orange and the subsequent Glorious Revolution, the installation never took place. Berwick in all conscience could not remain as the Colonel of The Blues' Troop he had served since 1682; he refused to betray his old patronne. Officers were required to answer 'three questions' designed by the King to test their loyalty. Berwick was with his father at Salisbury in November 1688, when key units deserted to the Prince of Orange. King James II was overthrown in December 1688 and fled to France, and Berwick went into exile with him.
In 1689 Berwick accompanied his father to Ireland and fought in the Irish campaign at the Siege of Derry, the Battle of Cavan and the Battle of the Boyne during which he led a charge, was unhorsed and almost killed in the melee. When his father departed for France after the Boyne, Berwick remained with the Jacobite Irish Army during the retreat to Limerick.
On 2 August he was one of the generals, with Patrick Sarsfield and Boisselau, who shored up the defences at Limerick awaiting the Williamite assault; thereafter they rode north across the Shannon with a few Guards. On 22 June 1691, Berwick was with the French general Charles Chalmot de Saint-Ruhe, at Aughrim, a site of his choosing when General de Ginkel appeared over the hill with a superior force of 18,000 Williamites. The defenders were surrounded on one side by peat bog, and on the other Kilcommodon Hill. Berwick was with Sarsfield's corps on the Irish right, who had an uncommitted reserve, when The Blues smashed through the Irish lines on the left, broke the Irish Dragoons, and caused a general panic to ensue. General St Ruhe was decapitated by a stray cannonball, but Sarsfield was too late to rescue the situation. He retired with Berwick to the relative safety of Limerick, which de Ginkel besieged on 25 August. Under the terms of Treaty of Limerick, signed on 3 October, all Irish contingents were banished to the continent forever. These soldiers became known as the Wild Geese. James II created Berwick Colonel of the 1st Troop, Wild Geese. Berwick arrived too late at the siege of Cork with 4,000 French troops, but unable to effect a result, he withdrew; Marlborough marched west to Kinsale to deal with 18,000 Frenchmen. It was at this time that he undertook a number of secret visits to England on behalf of the Jacobite cause.
After his father's final exile, Berwick served in the French army under Marshal François-Henri de Montmorency, duc de Luxembourg, including at the battles of Steenkerque. Luxembourg fell into William's trap set against superior numbers, but reinforcements failed the Allies, and the French rallied to send the Maison Militaire du Roi infantry downhill. Berwick was in the charge of the division that broke English lines. They were driven from the field with heavy losses. Berwick was one of Luxembourg's principal officers, and in 1694 commanded the centre of a large French army. After several forced marches to entrap William, they crossed the Meuse again before stopping them near Neerwinden. Berwick struggled against the Foot Guards, who forced his men to retreat in the Landen. He was taken prisoner by his uncle, Charles Churchill, and ransomed for 30,000 florins; and later was exchanged for the wounded James Butler, 2nd Duke of Ormonde. The Irish peer was accused of allowing himself to fall into enemy hands. The scandal swept Whitehall Palace causing angry questions in Parliament.
At the same time a huge number of 400 ships bound for the Smyrna Convoy were taken by the French. Because of his support for his father and service in the French army against England, he was attainted in 1695 by Act of Parliament rendering his British peerages forfeit.
As a soldier, Berwick was highly esteemed for his courage, abilities and integrity. But when his uncle, Marlborough, challenged the French to fight at Liege, Louis-François de Boufflers retreated. In 1703 he took part in the Battle of Ekeren. In June 1704, Berwick commanded a combined Franco-Spanish army, but they did not seriously challenge the enemy, only taking a few of the Barrier Fortresses. By July 1706 Berwick had established increasing dominance in the north of Spain as the Bourbons' premier general. In August partisans forced the Earl of Galway to evacuate Madrid allowing Berwick into winter quarters. As a result of distinguished service in the War of the Spanish Succession, he became a French subject and was appointed a Marshal of France after his successful expedition against Nice in 1706.
Louis XIV was in the habit of sending his marshals lengthy orders. In 1707 he wrote to Louis Joseph, Duke of Vendôme: "...it will be absolutely necessary for the Duke of Berwick to detach a similar proportion and to send a sufficient number of troops to the Elector of Bavaria..." The French allocated 75 battalions and 140 squadrons to the Rhine front, giving Berwick a comfortable numerical superiority. On 25 April 1707, Berwick won a great and decisive victory at the Battle of Almanza, where an Englishman at the head of a Franco-Spanish army defeated Ruvigny, a Frenchman at the head of an Anglo-Portuguese-Dutch army. Five English, six Dutch, and three Portuguese regiments were captured with all the cannon and regimental colours. The defeat ended Allied hopes of putting the Habsburg candidate on the Spanish throne. Berwick was "the brave English general who had defeated the French" to confused Tories. After Almanza, Berwick was created Duque de Liria y Xérica (English: Duke of Liria and Jérica) and Lieutenant of Aragon by Philip V of Spain in 1707, and Duc de Fitz-James (English: Duke of Fitz-James) in the Peerage of France by Louis XIV in 1710. But in the meantime in July 1707, Berwick heard the Allies had left Maastricht and sent 34 battalions and 75 squadrons north to meet Prince Eugene's army. In the spring of 1708, a Dutch force raided Berwick's camp at Cenco, killing all the men in their tents, with Berwick expressing shock at the "barbarous" action. By July Berwick had caught up with Vendôme's army at Oudenarde, but was yet to arrive, anticipating Vendôme would retreat to join up his force at Gavre six miles away. But Berwick was at Givet on River Meuse when he heard of Vendôme's heavy defeat. Berwick rescued 9,000 stragglers, using them to garrison Douai, and then moved toward Lille, where he prepared to be besieged. However, the English arrived there first and managed to dismantle the defensive ramparts before he could reach them. Nonetheless, on 3 August, Berwick reckoned a siege was afoot, reinforcing the garrison with 20 battalions and 7 squadrons of dragoons with horses. Lille was a heavily defended and fortified town, important to King Louis. Astutely, Berwick realized Marlborough was trying to bring his battered army to battle, despite constant missives from Versailles ordering an immediate attack. On 22 October Marshal Boufflers finally gave up and marched out to Douai. But crucially, Berwick's army remained intact.
