Chronicle of Abbot Ralph of Coggeshall

The Chronicle of Abbot Ralph of Coggeshall (Chronicon Anglicanum) is an indispensable medieval history that brings to life centuries of English and European affairs through the eyes of a learned Cistercian monk. Ralph of Coggeshall, abbot of the Abbey of Coggeshall in Essex in the early 13th century, continued and expanded his community’s chronicle, documenting events from the Norman Conquest of 1066 into the tumultuous reign of King Henry III. Blending eyewitness testimony, careful compilation, and the monastic commitment to record-keeping, this chronicle offers a rare narrative of political intrigue, royal power struggles, and social upheaval in England and beyond. Ralph’s work captures the reigns of pivotal figures such as Richard I and King John, providing invaluable insights into their characters, decisions, and the forces that shaped medieval rule. More than a simple annal, Chronicon Anglicanum conveys the texture of medieval life and governance, making it a rich source for scholars and readers fascinated by English history, monastic authorship, and the shaping of the medieval world.

Chronicle of Jean le Bel Volume 1. After the feast of Saint Lambert, in the month of September [17th September], in the year of grace 1339, King Edward departed from Vilvoorde in Brabant1 to burn and lay waste the kingdom of France and to fight King Philip of Valois, who, as he claimed, held it by force and wrong. With him, from his realm of England, were sixteen hundred men-at-arms of very noble chivalry. Among them was the Bishop of Lincoln, valiant and bold, who had long laboured in these affairs. There was also the young Earl of Derby2, son of Sir Henry of "the Crooked Neck," Earl of Lancaster, who later performed so many feats of arms in so many places that he ought to be accounted valiant and more than valiant, as indeed he was regarded. After the death of his father, who had been a most worthy man, the noble King Edward granted him the title of Duke of Lancaster, and so he was called duke, as he still is.

Bourgeois de Valenciennes. It happened a long time after the matters spoken of above, about the feast of Saint John the Baptist in the year 1344, that King Edward of England sent forces into Gascony, where the duke of Normandy was waging war and had gained towns and castles. He sent there the Earl of Derby1, the Earl of Pembroke2, and my lord Walter of Mauny, with many others. These took and won the castle of Bergerac and more than forty towns and fortresses, and they pressed the French so hard that they defeated them. There were taken prisoner the Count of L’Isle, the Count of Valentinois, the Viscount of Murendon, the Viscount of Monder, the Viscount of Villemur, the Viscount of Bouquentin, my lord Charles of Poitiers, my lord Roger, brother of the Count of Comminges, and many other counts, viscounts, and some three hundred knights. The others were slain or drowned in a river called the Viane. This battle took place in the year 13453.

Note 3. The original text has 1344. The Battle of Bergerac was fought in August 1345. Froissart, Book 3, Chapters 210-211: "At sunrise the English, who had been ordered to make the assault by water in their ships, were fully prepared. The captains among them were the Earl of Pembroke and the Earl of Hereford. With them were many young knights and squires who had come there of their own eager will, to advance themselves in arms. In that fleet there was a great number of archers. They advanced swiftly and came up to a great barrier that stood before the palisade, which was soon broken down and cast to the ground. The men of Bergerac and the commonalty of the town perceived that in no way could they endure against that assault. They began to lose heart and went to the Count of L’Isle and to the knights who were there, and said to them: 'My lords, consider what you wish to do. We are in danger of being utterly lost. If this town is taken, we shall lose our goods and our lives as well. It would be better for us to surrender it to the Earl of Derby than to suffer greater harm.' Then the Count of L’Isle answered and said: 'Come, let us go where you say the danger lies, for we will not surrender it in this manner.' Thereupon the knights and squires of Gascony who were there came forward toward the palisades and set themselves to the defense with great courage. The archers, who were in their barges, shot so thickly and so straight that scarcely anyone could appear without putting himself in danger of being slain or grievously wounded. Within the town, together with the Gascons, there were some two hundred Genoese crossbowmen, who did them great service; for they were well shielded against the shooting of the English and sorely troubled the English archers throughout that day. There were many wounded on both sides. At length the English, who were in their ships, pressed the attack so vigorously that they broke down a great section of the palisade. When those of Bergerac saw the peril, they came forward and asked for a truce, that they might take counsel concerning their surrender. It was granted to them for the remainder of the day and the following night until sunrise, on condition that they should not strengthen themselves in any way. Thus each side withdrew to its lodgings. That night the barons of Gascony who were there held a great council, to determine how they might conduct themselves. When they had taken counsel, they had their horses saddled and their goods loaded, mounted, and departed about midnight. They rode toward the town of La Réole, which is not far from there. The gates were opened to them; they entered within and lodged and quartered themselves throughout the town."

Around 25th August 1345 Henry of Grosmont, Earl of Derby [aged 35], commanded the English forces at Bergerac, Dordogne during the Battle of Bergerac. The English army including Walter Manny 1st Baron Manny [aged 35] won a decisive victory over the French with Henri Montigny captured.

The ransoms alone made a fortune for many of the soldiers in Derby's army, as well as Derby himself, who was said to have made at least £50,000 from the day's captives, and sealed his reputation as 'one of the best warriors in the world'.

Inquisitions Post Mortem 118. 118. Henry duke of Lancaster.

Writ, Wyndesore, 25 March, 35 Edward III [1361].

Chronicle of Geoffrey le Baker of Swinbroke. In the nineteenth year of the king's reign, Henry, Earl of Derby,1 later created Duke of Lancaster, and the Earls of Devon and Pembroke, as well as Lord Ralph Stafford; not yet Earl of Stafford but still a baron, and Lord Walter de Mauny, were sent to Gascony. There, having conquered walled towns and castles, they won many glorious battles with great bravery. The town of Aiguillon,2 which they captured by assault, was placed under the guardianship of Ralph of Stafford. Afterward, they moved against other towns, such as Bergerac, which due to its strength was called "the chamber of the French," and also Saint-Jean, La Réole, and many other large, strong, and well-fortified places, which they captured through great effort and perilous assaults. In these campaigns, the Duke of Lancaster fought in underground tunnels, which were being dug to undermine the towers and walls, and suffered fierce attacks from the valiant defenders, fighting hand-to-hand against the besieged. And, something unheard of before, he knighted both Gascon and English soldiers in those very tunnels. Indeed, by conquering towns, cities, castles, and fortresses numbering two hundred and fifty, he marched across a large part of Gascony and advanced as far as Toulouse. There, he invited the ladies of Toulouse and noble maidens, through letters, to dine with him, his fellow nobles, and Lord Bernard de Libreto,3 a loyal Gascon. But, with God's protection, he did no harm to the city or its inhabitants, except for instilling in them unbearable terror, as those who had been besieged later told me. The terror was such that even mendicant friars took up arms, and the Prior of the Carmelite order of the Blessed Virgin Mary in Toulouse, bearing a silver banner with a golden image of the Virgin, led the citizens of his quarter from the walls. He raised his banner in defence,4 and by this display, he stirred pious devotion in the duke and many in the army, though some mocked him as well.

Set, civitatem Deo conservante, nihil eius incolis malefecit, nisi quod terrorem intollerabilem, ut obsessi mihi retulerunt, eiis intulit; ita quod, religiosis mendicis ad arma compulsis, prior Carmelitarum beate Marie Tolose, sub vexillo argenteo ymaginem auream beate Virginis habente, de quarterio sui incolatus civibus prefectus, ostendens suum vexillum ad muros, per armorum errancias descriptum ducem ad devocionem piam et quam plures de exercitu, atque nonnullos ad derisionem, provocavit.

Note 1. Henry of Grosmont succeeded as earl of Lancaster, 22nd September 1345, and was created duke on the 6th March 1352. Hugh Courtenay succeeded as earl of Devon in 1341; died in 1377. Laurence de Hastings was created earl of Pembroke, 12th October 1339; died in 1348. Ralph de Stafford succeeded as baron Stafford in 1308, and was created earl on the 5th March 1351; died in 1372.

Baker is very confused as to the capture of the different places. Bergerac was first taken on the 24th August 1345, Aiguillon, early in December, La Réole, in January 1346. The Saint-Jean-d'Angely was not taken till September 1346. Derby did not go near Toulouse, although it is not impossible that some incursion was made thither. Baker says that he had his information from persons who were besieged there; but he was quite capable of confusing events, and he is most probably referring to the expedition of 1349.

Note 2. Aiguillon, is located at the confluence of Rivers Lot and Garonne. Bergerac is on the River Dordogne. La Réole and Saint-Jean-d'Angely are both on the Garonne downstream of Aiguillon.

Note 3. Bernard, sire d'Albret; died 1358.

Note 4. This seems to mean: by the procession of his banner, on which the picture of the Virgin stood for his armorial device.
