Portrait of a man in armor, half-length, traditionally identified as James Fitzjames, 1st Duke of Berwick, Marshal of France (1670-1734)

James Fitzjames was the illegitimate son of King James II, born in France to his mistress Arabella Churchill before his ascension to the throne in 1685. He was educated in France at the College of Juilly, the Collège du Plessis (the Sorbonne), and at the Jesuit College of La Flèche. After his studies, he began a long and illustrious military career. He was present at the Siege of Buda (1686) in the service of Charles V, Duke of Lorraine. He later returned to Hungary to participate in the Battle of Mohács (1687). After the Glorious Revolution (1688), which saw his father deposed, Berwick followed the ex-king into exile in France, and later accompanied him into battle during the Irish Campaign. After his father's final exile, Berwick served the French military under Marshal François-Henri de Montmorency, Duke of Luxembourg. He was esteemed for his courage and integrity on the battlefield, where he eventually lost his life at the Siege of Phillipsburg (1734) during the War of Polish Succession.
