Question: Which battle in the Hundred Years' War did Thomas de Camoys command?
Context: Lord Thomas de Scales or Thomas Scales de Newselles or Thomas Scalles KG (1397 – 25 July 1460), 7th Baron Scales, Knight of the Garter from 1426 was one of the main English commanders in the last thirty years of the Hundred Years' War.  The son of Robert de Scales, 5th Baron Scales (c. 1372–7 December 1402), he succeeded his brother Robert de Scales, 6th Baron Scales (died July 1419) as baron. Katherine Mortimer, Countess of Warwick (1314 – 4 August 1369) was the wife of Thomas de Beauchamp, 11th Earl of Warwick KG, an English peer, and military commander during the Hundred Years War.  She was a daughter and co-heiress of Roger Mortimer, 1st Earl of March and Joan de Geneville, Baroness Geneville. The barony of Camoys was created twice.  From 26 November 1313 to 1 April 1335 Ralph de Camoys (d.1336) was summoned to Parliament by writ, and is thereby held to have become Baron Camoys of the first creation.  Ralph de Camoys (d.1336) married firstly, Margaret de Brewes, daughter of William de Brewes, 1st Lord Brewes (d.1291), and secondly, Elizabeth le Despenser, daughter of Hugh le Despenser, 1st Earl of Winchester (executed 27 October 1326). Thomas de Beauchamp, 11th Earl of Warwick, KG (c. 14 February 1313 – 13 November 1369) was an English nobleman and military commander during the Hundred Years' War.  In 1348 he became one of the founders and the third Knight of the Order of the Garter. The Lancastrian War was the third phase of the Anglo-French Hundred Years' War.  It lasted from 1415, when Henry V of England invaded Normandy, to 1453 when the English lost Bordeaux.  It followed a long period of peace from the end of the Caroline War in 1389.  The phase was named after the House of Lancaster, the ruling house of the Kingdom of England, to which Henry V belonged.  After the invasion of 1419, Henry V and, after his death, his brother John of Lancaster, Duke of Bedford, brought the English to the height of their power in France, with an English king crowned in Paris.  However, by that time, with charismatic leaders such as Joan of Arc and La Hire, and with England losing its main allies, strong French counterattacks had started to win back all English continental territories, except the Pale of Calais (which was only captured in 1558).  Charles VII of France was crowned in Notre-Dame de Reims in 1429.  The Battle of Castillon (1453) was the last battle of the Hundred Years' War, but France and England remained formally at war until the Treaty of Picquigny in 1475.  English, and later British, monarchs would continue to nominally claim the French throne until 1801, though they would never again seriously pursue it. Thomas de Camoys, 1st Baron Camoys (c. 1351 – 28 March 1421), KG, of Trotton in Sussex, was an English peer who commanded the left wing of the English army at the Battle of Agincourt in 1415. The Battle of Agincourt ( ; in French, Azincourt ] ) was a battle of the Hundred Years' War that resulted in a English victory.  The battle took place on 25 October 1415 (Saint Crispin's Day) in the County of Saint-Pol, Artois, some 40 km south of Calais (now Azincourt in northern France). Elizabeth Mortimer, Baroness Camoys (12 February 1371 – 20 April 1417) was an English noblewoman, the granddaughter of Lionel of Antwerp, 1st Duke of Clarence, and great-granddaughter of King Edward III.  Her first husband was Sir Henry Percy, known to history as 'Hotspur'.  She married secondly Thomas de Camoys, 1st Baron Camoys.  She is represented as 'Kate, Lady Percy,' in Shakespeare's "Henry IV, Part 1", and briefly again as 'Widow Percy' in "Henry IV, Part 2". Jean-François Thomas de Thomon (April 12 [O.S. April 1] 1760 – September 4 [O.S. August 23] 1813 ) was a French neoclassical architect who worked in Eastern Europe in 1791–1813.  Thomas de Thomon was the author of Old Saint Petersburg Stock Exchange and Rostral Columns on the spit of Vasilievsky Island in Saint Petersburg and the first building of the Odessa Theatre, destroyed by fire in 1873.  Thomas de Thomon, graduate of the French Academy in Rome, "imported" the high classicism practiced by this school in 1780s into Russia and thus contributed to the formation of Russian national variant of neoclassicism practiced during the reign of Alexander I. Hugh de Camoys, 2nd Baron Camoys (1413–1426) succeeded his grandfather Thomas de Camoys as Baron in 1419.
