About Henri de Beaumont, Earl of Buchan



which say that Henry died before 10 March 1340


He fought in the Scottish Wars in 1302, with King Edward I. He was invested as a Knight before 1308. He held the office of Joint Warden of Scotland (south of Forth) in 1308. In 1307/8 he was granted large estates in Lincolnshire. He was created 1st Lord Beaumont [England by writ] on 4 March 1308/9. He held the office of Lordship of the Isle of Man between 16 March 1310 and 20 October 1312. He held the office of Envoy to France between 1312 and 1331. In 1312/13 he had livery of lands from John Comyn, Earl of Buchan. He fought in the Battle of Bannockburn on 24 June 1314. He held the office of Constable of England in 1322. He was invested as a Privy Counsellor (P.C.) in 1322. He fought in the Battle of Boroughbridge on 16 March 1321/22. On 5 June 1323 he was imprisoned for contempt and disobedience at the Council. In 1334 he received a grant of Loughborough Castle, for siding against the King and preventing the King's escape. He was created 1st Earl of Buchan [England by writ] on 22 January 1333/34. He held the office of Constable of England in 1336. He held the office of Justiciar [Scotland] in 1338.

    His descendants appear not to have used the title of Earl of Buchan.

Henry de Beaumont, jure uxoris Earl of Buchan and suo jure 1st Baron Beaumont (died March 10 , 1340 ) was a key figure in the Anglo-Scots wars of the thirteenth and fourteenth centuries, known as the Wars of Scottish Independence. He was a veteran campaigner who participated in every major engagement, from the Battle of Falkirk in 1298 to the Battle of Halidon Hill in 1333. Although not now a widely-known figure, he was, nevertheless, of considerable military and political importance. His long experience of the Scottish wars led him to develop a battle technique later used to great effect at Crécy and Agincourt. As one of a group of Anglo-Scots nobles known as the 'disinherited' – those who had fought against Robert Bruce – he was to do much to overturn the peace between England and Scotland established by the Treaty of Northampton and bring about a Second War of Scottish Independence. By his marriage shortly before July 14, 1310 to Alice Comyn (died July 3, 1349 ), the niece and heir of John Comyn, Earl of Buchan, he was recognised as Earl in right of his wife.


Henry de Beaumont was the eldest son of Sir Louis de Brienne, Knt., (d. after September 1 , 1297 ) who was in right of his wife Agnés de Beaumont, Vicomte of Beaumont in Maine and Seigneur of Beaumont-le-Vicomte (alias Beaumont-sur-Sarthe), Sainte-Suzanne, la Fleche, Fresnay, le Lude, etc. He was the grandson of John of Brienne , King of Jerusalem.

The children of Henry and his wife Alice Comyn, (granddaughter of Alexander Comyn, Earl of Buchan ) Lord High Constable of Scotland include:

  • Elizabeth Beaumont c1320-1400 who married Nicholas Audley, 3rd Baron Audley 1328-1391.
  • John de Beaumont c1318, 2nd Lord Beaumont who married Eleanor Plantagenet, great granddaughter of King Henry III.
  • Isabel de Beaumont, married Henry of Grosmont, 1st Duke of Lancaster. They were ancestors of England's Royal House of Lancaster, with King Henry IV of England being the couple's grandson.

First campaigns

He first took up military service with Edward I while he was campaigning in Flanders in 1297 against Philip IV of France. When Edward returned to England the following year to deal with the after effects of the defeat of his northern army by the Scots at the Battle of Stirling Bridge , he was accompanied by Beaumont. In the ensuing battle of Falkirk , Beaumont was one of the young knights who had his horse killed from under him by the spears of William Wallace's schiltrons. Beaumont again attended Edward I in the Scottish wars in 1302.

Landed estates

Beaumont obtained large grants of manors and lands, including Folkingham , Barton-upon-Humber , and Heckington, Lincolnshire , from King Edward II. He was summoned to parliament from March 4, 1309, to October 20 , 1332 , by Writs directed to Henrico de Bellomonte, whereby he is held to have become Lord Beaumont. He was again summoned to the English parliament from January 22 , 1334 through to November 16 , 1339 as Earl of Buchan. He sat in the Scottish parliament of Edward Balliol on February 10, 1334 , as Earl of Buchan.

He had a grant of the Lordship of the Isle of Man in 1310. The next year he and his sister, Isabel de Vesci, were banished from Court, but soon returned. In 1313 he and his sister acquired the reversion of the manors of Seacourt, Berkshire, and Tackley, Oxfordshire, which, upon her death without issue in 1334, fell to him. Between 1317 and 1321 his wife succeeded to the English estates of her sister, Margery Comyn, wife successively of Sir John Ross and Sir William de Lindsay . He purchased the Lordship of Ditchburn, Northumberland, in 1320.


At Bannockburn in 1314, he fought on the English side, both the first and second day of the battle, and was one of those who accompanied Edward II in his flight from the field, and was subsequently deprived of his Scottish Earldom of Buchan by King Robert The Bruce.

The Disinherited

In the November after Bannockburn Beaumont was one of those affected by the sentence of forfeiture passed by the Scottish parliament against all those with land and title in Scotland who continued to fight with the English. Thus was created that class of nobility known as the disinherited. Although this also included men of greater standing like David III Strathbogie, titular Earl of Atholl , Beaumont was to prove by far the most determined in the pursuit of his lost honours.

He fought on the side of Edward II at the Battle of Boroughbridge in 1322. However, when Edward II entered into truce negotiations with the Scots in May 1323, Beaumont, hitherto a close associate of the king, argued against any agreement which disregarded the claims of the disinherited, for whom he had become the leading spokesman. Edward overruled Beaumont and the two quarreled. Beaumont was briefly imprisoned for contempt and disobedience at the Privy Council (of which he was a member), after which he retired from Court to continue his intrigues in exile, eventually joining forces with Edward's estranged wife, Queen Isabella , and her lover Roger Mortimer, 1st Earl of March. His cause, however, was not furthered by the coup of 1327, in which Isabella and Mortimer deposed the king and replaced him with his under-age son, Edward III .

Anxious to break the deadlock in the north Isabella and Mortimer persuaded Parliament to accept the terms of the Treaty of Northampton, which ignored, once again, the claims of the disinherited. Many of the senior nobility were ashamed of what they considered to be a shameful peace; and when Henry, 3rd Earl of Lancaster rose in revolt in late 1328 he was joined by Henry Beaumont, Thomas Wake, Henry Ferrers, Thomas Rosselin and David de Strathbogie, the latter now married to Beaumont's daughter, Katherine. This was the nucleus of the party soon to be prominent supporters of Edward Balliol , the son of the former King John Balliol . The rising was short-lived; and when Lancaster submitted in January 1329, Wake and Strathbogie also made their peace. Not so Henry Beaumont, who was specifically excluded from pardon, going in to exile to plot Mortimer's downfall. When the Edmund of Woodstock, 1st Earl of Kent was arrested in March 1330 and charged with conspiring to restore Edward II, whom he had been deluded into believing was still alive, he alleged at his trial that Beaumont had met him in Paris and told him that his plot would be supported from Scotland by the armed intervention of Donald Earl of Mar , a personal friend of the ex-king. Kent was executed and Beaumont would never be allowed to return to England while Mortimer and Isabella held on to power.

Edward de Balliol

The peace of Northampton seemed to end forever the hopes of the disinherited. Two things changed this: the death of King Robert Bruce in 1329, followed in 1330 by a palace coup in England, which saw the overthrow of Roger Mortimer and the assumption of full powers by King Edward III . In Scotland, Robert's infant son, David II was king, bringing the inevitable tensions that follow from a royal minority. Edward, for the time being at least, maintained the peace with Scotland, but he was known to share the views of many of his countrymen that Northamption was a turpis pax-a shameful peace. In 1330 Edward III would make a formal request to the Scottish Crown to restore the lands of Beaumont's earldom to him, which request was refused.

From near extinction, the cause of the disinherited was now revived; but it needed direction and focus. Above all, it needed a cause, something greater than frustrated ambition. By the early 1330s the cause had become Edward Balliol, in the judgement of some the righful King of Scotland.

Edward Balliol is clearly an important figure; but it is difficult to decide if he was the author of his own ambitions or a lever for the designs of others. He took no part in the first war, and it is doubtful if he had any military experience before he came to Scotland in 1332. The driving force, as always, was Henry Beaumont, the arch conspirator of the disinherited. It was he who formed the 'party' of the disinherited in the period after the peace of Northampton: he who encouraged Balliol, with Edward III's approval, to leave his French estates and come to England. He was a seasoned campaigner, who had been present both at Bannockburn and the Battle of Boroughbridge, and learned much from both encounters. It is almost certain that he was the architect of Balliol's victory at the Battle of Dupplin Moor where he fought; and he is likely to have advised Edward on the tactics that brought him the first great military success of his career at the Battle of Halidon Hill , the exact foretaste of the later triumph at Crécy . Beaumont, moreover, provided much of the financial support that allowed the impecunious Balliol to descend on Scotland at the head of an army of freebooters. But his principal loyalty was to himself and then to Edward III; for, as time would show, Edward Balliol was a hook on which he hung the cloak of his ambitions.

War by Other Means

In assuming power Edward would have been mindful of the support he had received from Beaumont. He would also have been aware that while the restless earl was a useful friend he was also a dangerous enemy. Beaumont's shifting loyalties since 1323 had all been dictated by his overriding desire to recover the earldom of Buchan. But Edward embraced the cause of the disinherited for reasons more subtle than simple gratitude: for Beaumont's tireless plotting eventually provided the occasion to set aside the peace of 1328.

Before the end of 1330 Edward started to make strong diplomatic representations on behalf of Beaumont and Thomas Wake, the claimant to the Lordship of Liddesdale , the only two noblemen to be officially recognised as disinherited by the English and Scottish governments. He wrote to King David in December, requesting restoration of the lands of the 'Earl of Buchan' and the 'Lord of Liddesdale'. But Edward must have realised that there was little chance of the Scots accepting Beaumont and Wake in their midst. It would make little sense to hand over important lands in the west march and the north-east of Scotland to men whose personal and political loyalties lay with a potential enemy, and who were widely known to be vehement opponents of the Treat of Northampton. David's guardian Thomas Randolph, Earl of Moray , was obviously conscious of this, and Edward's request was effectively ignored. Beaumont now began to seek restitution by other means.

Sometime between 1330 and 1331 Beaumont conceived a plan to invade Scotland at the head of a private army, headed by himself and Edward Balliol. The first contacts between Balliol and Beaumont had been in 1330. In 1331 these approaches became more serious. In June both he and Strathbogie crossed the Channel to visit the exile in Picardy . Beaumont returned in August and again in November, when he was accompanied by Walter Comyn. The Brut Chronicle contains a colourful story, not repeated in any other source, that Balliol had incurred the displeasure of the King of France, and had to be rescued from imprisonment by Beaumont's special pleadings. What is certain is that he was finally persuaded to leave France and come to England in the winter of 1331. He was settled in the manor of Standal in Yorkshire, a property belonging to Beaumont's sister, the Lady Vesci. Beaumont then visited King Edward and obtained an important concession: he would not allow the disinherited to cross the border in open breach of the Treaty of Northampton, but he would not stop them sailing from English ports. By the summer of 1332 all was ready and a small army of archers and men-at-arms sailed from various ports in Yorkshire, landing on the coast of Fife in August.

Battles and Crowns

Soon after landing the army, under the skillful command of Beaumont, confronted and defeated a much larger Scottish force at the Battle of Dupplin Moor in August 1332, using an effective, and murderous, combination of infantry and archers. Building on this victory, the army advanced on Scone, where Edward Balliol was crowned King of Scots on 24 September. The coronation was a tense and unhappy occasion, for the new king and his small army were isolated in a sullen and hostile country. At the banquet after the coronation ceremony it is said that the guests remained fully armed, save for their helmets. There was good reason for this; for it is also said that the local people attached themselves to Balliol more from fear than love. The terror of the new regime soon spread, and the priors of St. Andrews wrote of the lordship of Edward Balliol and Henry Beaumont, and their inability to collect the dues from their church at Fordun 'for fear of the said Lord Henry.'

It was clear that, in the absence of widespread native support, the adventure could only prosper with the open support of King Edward. As bait Balliol wrote to him offering to cede all of south-east Scotland to England. This proposal was carried south by Henry Beaumont and David de Strathbogie, who came to attend the meeting of Parliament at York. Before they could return Balliol and what was left of his army was surprised by a party of Bruce loyalists at Annan and chased out of the country. All of the expense and effort of the past years had come to nothing.

Castles of Sand

In January 1333 Edward finally dropped the pretence of neutrality: Edward Balliol was formally recognised as King of Scotland and promised military aid. Subsidies were now paid to Beaumont and the others, to help prepare for a fresh invasion. In July a fresh Scots army was cut to pieces at Halidon Hill, just outside Berwick-upon-Tweed , using the same battle tactics as Dupplin Moor. Once again the disinherited advanced into Scotland. Henry Beaumont was able to return to Buchan where, according to Andrew Wyntoun, he repaired the old Comyn stronghold of Dundarg on the Aberdeenshire coast in 1333/4, which had been destroyed by Robert The Bruce in 1308:

The Beaumont went intil Buchan; And there, Dundarg of lime and stane He made stoutly, and therin lay.

Even so, the hold of the disinherited lords was no more certain than before. By September 1334 Edward Balliol, faced with a full-scale revolt, sent urgent appeals to England for yet more assistance. To make matters even worse his followers, who had been brought together by greed for land, were driven apart by the very same greed. In a dispute over the estates of Alexander de Mowbray, killed at Annan in 1332, Balliol was unwise enough to quarrel with Beaumont who, in the fashion of Achillies , withdrew from Court in a fit of picque, to Dundarg.

Balliol's regime collapsed, and for the second time in his career he fled across the border . Beaumont, in the meantime, was besieged in Dundarg by Andrew de Moray , the new Guardian of Scotland. Under continual attack, and running short of supplies, he was compelled to surrender on December 23 , 1334 . After a brief imprisonment he was ransomed and returned to England in time for the summer campaign of 1335. While he came back to Scotland it is uncertain if he ever saw Buchan again. Dundarg was destroyed for the second and last time in its history.


Beaumont was an active participant in Edward's invasion of Scotland in 1335, the largest he ever mounted on behalf of his hapless protege; but the results were no more lasting than before. In November the uncertain gains of the summer were wiped out by Moray's victory over Strathbogie at the Battle of Culblean.

After Culblean Balliol's shadowy kingdom virtually disappeared. Perth was retaken. Only Cupar Castle in Fife and remote Lochindorb kept his cause alive. In Lochindorb the widow of Strathbogie, Kathrine Beaumont, daughter of Henry Beaumont, had been under siege by Moray since late 1335. The rescue of Kathrine Beaumont was to allow Edward III to drape a cloak of high chivalry over one of his most destructive military adventures. English action took the form of a large-scale punitive raid, intended to knock out Scots resistance and, at the same time, forestall a possible French landing in the north-east. Edward initially gave command to Henry of Lancaster, Beaumont's son-in-law; although he eventually decided to take charge in person. Edward advanced into Aberdeenshire in the summer of 1336. Beaumont came with him , as did Edward Balliol, surely a more persistent student of spiders than Robert Bruce had ever been. Kathrine was duly rescued, while the north-east was subject to widespread destruction.

It was in this season that Henry Beaumont embarked on his last actions in Scotland, by seeking vengeance against those whom he held responsible for the death of his son-in-law. The Pluscarden Chronicle describes his actions thus; Henry Beaumont, to avenge his son-in-law, the Earl of Atholl, who was slain at Culblean, either cast into prison or put to cruel death all who had taken part in the engagement in which he was slain; whereby much innocent blood was shed.

In 1337 Edward III, in beginning the opening rounds of what was to become the Hundred Years War , virtually lost all interest in the future well-being of Balliol and his hopeless cause. Even Henry Beaumont, the most determined of the disinherited, had had enough. Rather than return to Scotland with Balliol the old warrior accompanied King Edward to the Low Countries, from whence he had come with his royal grandfather in 1298, where he died in March 1340, his long struggle incomplete. His son, John, never claimed the lost earldom of Buchan. When Beaumont's wife, Alice, died in 1349 the Comyn line of Buchan, which stretched back to the early thirteenth century, finally came to an end.
