Little is known of Grosmont's childhood and youth. Due to his uncle Thomas' increasingly hostile relations with King Edward II—culminating in his rebellion and execution in 1322—historian

Having no progeny, Thomas's possessions and titles went to his younger brother Henry, 3rd Earl of Lancaster, Grosmont's father. Henry of Lancaster assented to the deposition of Edward II in 1327, but fell out of favour with the regency of his widow
Queen Isabella and
Roger Mortimer. When Edward III, the son of Edward II, took personal control of the government in 1330, relations with the Crown improved, but by this time Henry of Lancaster was struggling with blindness and poor health. He was able to attend the new king's coronation on 1 February 1327, where he knighted Edward. Grosmont was knighted the same year, represented his father in

. It was, argues Fowler, conducive to Lancastrian relations with the crown that the new King and Grosmont were of a similar age and interests, and Grosmont was never to experience the reversals of fortune his father had faced.
Estates and finances
Originally heir to only the lordships of Beaufort and Monmouth, by 1327 it was looking probable that he would inherit most of the Lancastrian
patrimony. He was not yet independent from his father, from whom he received regular fundsamounting to £666 in 1332as well as grants from the English crown as a reward for his service and in recognition of his lack of a personal income. From early the next year, his father began transferring his

estates into Grosmont's name, giving him an independent income. In March 1337 he was one of six men Edward III promoted to higher levels of the peerage; one of his father's lesser titles, the
Earldom of Derby, was bestowed upon him. He was also granted a royal annuity of 1,000 marks (£ as of ) for so long as his father lived, and a number of lucrative estates and perquisites were settled on him. By this point Grosmont's future relationship with the crown was "actively assured" comments Fowler.
The early 1340s were a period of financial constraint for Grosmont due to his acting as a broker for a number of loans between the King and Flemish bankers. As well as undergoing a number of periods of imprisonment as a debtor, Grosmont was eventually to raise numerous large sums, including £969 to gain the release of the royal crown, which Edward had pawned, and £1,500 worth of jewels to free the King after he had offered himself as security for loans.

The Scots felt compelled to attempt to relieve the siege and an army of 20,000 men attacked the English at the

, from Berwick. Under intense bow-fire the Scottish army broke, the camp followers made off with the horses and the fugitives were pursued by the mounted English knights. Scottish casualties were numbered in thousands, including their commander and five earls dead on the field. Scots who surrendered were killed on Edward's orders and some drowned as they fled into the sea. English casualties were reported as fourteen; some chronicles give a lower figure of seven. About a hundred Scots who had been taken prisoner were beheaded the next morning, 20July. It is presumed that Grosmont took part in the battle, but it is possible that he was part of the detachment posted to ensure that the garrison of Berwick did not
sally. Berwick surrendered the day after the battle and Grosmont witnessed and sealed the articles of surrender and, a little later, the town's new charter.
Balliol having sworn fealty to David II, and because he intended to make Scotland subservient to the English, most Scots refused to accept Balliol as their monarch. In December 1334 Grosmont accompanied Edward III to

Grosmont's first trip abroad was probably to
Brabant in 1332. Six years later he travelled with Edward III to Flanders, which began inauspiciously when the King was "unable to pay or induce" his erstwhile allies to attack the French. Grosmont attended Edward's ostentatious meeting with the

for Edward providing the balance of payment due his allies. Throughout the year French naval forces
ravaged the English south coast. Edward III planned to invade France with his army of allies in 1339, but was finding it impossible to raise the money to pay them; he and his ambassadors had committed him to far greater expense than he could fund. Grosmont led part of Edward III's army when it finally
invaded France in September 1339.
Cambrai was besieged, the area around it devastated, and an unsuccessful attempt made to storm the town. The allied army pressed further into France, but the French refused to battle. In mid-October, the French issued a formal challenge to battle. Edward accepted and occupied a strong defensive position at
La Capelle which the French declined to attack; Grosmont commanded a
detachment. Having run out of provisions, money and weather suitable for campaigning, the allied army withdrew and dispersed. Grosmont arrived in Brussels with the army at the end of October, where the campaign was celebrated with a

Rather than continue the cautious war of sieges he was determined to strike directly at the French before they could concentrate their forces. He decided to move on Bergerac, which had good river supply links to Bordeaux, and would provide the Anglo-Gascon army with a base from which to carry the war to the French and sever communications between French forces north and south of the Dordogne. After eight years of defensive warfare by the Anglo-Gascons, there was no expectation among the French that they might make any offensive moves. Grosmont moved rapidly and took the French army at Bergerac by surprise on 26 August, decisively beating them in
a running battle. French casualties were heavy, with many killed or captured. Derby's share of the prisoner ransoms and the loot was estimated at £34,000, approximately four times the annual income from his lands.

A messenger got through to Grosmont, who was already returning to the area with a scratch force of 1,200 English and Gascon soldiers: 400 men-at-arms and 800 mounted archers.
After a night march Grosmont
attacked the French camp on 21 October while they were at dinner, taking the French by surprise. There was a protracted hand-to-hand struggle, which ended when the commander of the small English garrison in the castle sortied and fell upon the rear of the French. They broke and fled. Derby's mounted men-at-arms pursued them relentlessly. French casualties are uncertain but heavy. They are described by modern historians as "appalling", "extremely high", "staggering", and "heavy". Many French nobles were taken prisoner; lower ranking men were, as was customary, put to the sword. The ransoms alone made a fortune for many of the soldiers in Grosmont's army, as well as Grosmont himself, who was said to have made at least £50,000 from the day's captives. The Earl of Pembroke arrived after hostilities had ceased; Grosmont greeted him with the words, "cousin Pembroke, welcome. You are just in time to sprinkle holy water upon the dead."
Grosmont's four-month campaign has been described as "the first successful land campaign of... the Hundred Years' War", which had commenced more than eight years earlier. Modern historians have praised the generalship demonstrated by Grosmont in this campaign: "superb and innovative tactician"; "ris
ngto the level of genius"; "brilliant in the extreme"; "stunning"; "brilliant".
1346
The Duke of Normandy was placed in charge of all French forces in southwest France in 1346, as he had been the previous autumn. In March 1346 a French army under Duke John, numbering between 15,000 and 20,000, enormously superior to any force the Anglo-Gascons could field, marched on the town of
Aiguillon and besieged it on 1April. The town commanded the junction of the Rivers

Lot, meaning it was not possible for the French to sustain an offensive further into Gascony unless the town was taken. On 2April an ''
arrière-ban'', a formal call to arms for all able-bodied males, was announced for southern France. Grosmont, now known as Lancaster rather than Derby after the death of his father, sent an urgent appeal for help to Edward. Edward was not only morally obliged to succour his vassal, but also contractually required to; his

In July the main English army landed in northern France and moved towards Paris. Philip VI repeatedly ordered his son, Duke John, to break off the siege and bring his army north. Duke John, considering it a matter of honour, refused. By August, the French supply system had broken down, there was a

with very heavy losses, before Duke John's army could reinforce them. The English then
laid siege to the port of Calais.
Philip vacillated: on the day the siege of Calais began he disbanded most of his army, to save money and was convinced that Edward had finished his chevauchée (large-scale mounted raid) and would proceed to Flanders to ship his army home. On or shortly after 7September, Duke John made contact with Philip, having shortly before disbanded his own army. On 9September Philip announced that the army would reassemble at

. These offensives completely disrupted the French defences in the region and shifted the focus of the fighting from the heart of Gascony to or more beyond its borders. Few French troops had arrived at Compiègne by 1October and as Philip and his court waited for the numbers to swell, news of Lancaster's conquests came in. Believing that Lancaster was heading for Paris, the French changed the assembly point for any men not already committed to Compiègne to Orléans, and reinforced them with some of those already mustered, to block this. After Lancaster turned south to head back to Gascony, those Frenchmen already at or heading towards Orléans were redirected to Compiègne; French planning collapsed into chaos.

, which was held by the crown. It is a sign of Edward's high regard for Lancaster that he bestowed such extensive privileges on him. The two men were second cousins through their great-grandfather King
Henry III and practically coeval (Edward was born in 1312), so it is natural to assume that a strong sense of camaraderie existed between them. Another factor that might have influenced the King's decision was the fact that Henry had no male heir, so the grant of the dukedom was effectively made for Grosmont's lifetime only, and not expected to be hereditary.

. This almost led to a duel between the two men in Paris, which was only averted by the personal intervention of the French king who, Fowler suggests, was himself unclear which one was the injured party—Grosmont for his original accusation of kidnapping, or Brunswick for its unchivalric intimation. In the event, John held that Grosmont was the offended party. Travelling to Paris with a retinue of 50 knights, he was met sumpuously. Although John attempted to reconcile the two dukes, this proved impossible; it was not until the day of the joust that he declared the meeting void, with neither costs nor penalty for either to pay. While Grosmont's duel may have come to nothing, argues Fowler, more importantly, his lengthy sojourn abroad allowed him to do intelligence on the French court and assess its military or political divisions.

Treaty of Guînes, this policy proved unsuccessful, and by the following year full-scale war between England and France flared up again. On the English side, this may have been in part due to Grosmont's intelligence reports, in which he probably reported the divisions in the French aristocracy under John while emphasising the useful contact he had made and the friendly overtures he had received from
Charles, the new King of Navarre, who owned several strong—and strongly garrisoned—castles in Normandy, all of whose

longbowmen. They were reinforced by 200 Normans under
Philip of Navarre. The English commander
Robert Knolles joined Lancaster in
Montebourg with a further 800 men detached from English garrisons in Brittany. The historian
Clifford Rogers suggests that these 2,300 men were reinforced by up to 1,700 men from Navarrese-held fortifications over the following month.
Chevauchée
Lancaster's main objective was to relieve the besieged Navarrese strongholds of Pont-Audemer,
Breteuil and
Tillières-sur-Avre. Lancaster's small army set off into French-controlled Normandy on 24 June. Their journey took the form of a . All participants were mounted and moved relatively rapidly for armies of the period. Villages were looted and razed, as were towns and fortifications weak enough to be easily captured; stronger places were ignored. Parties spread out from the main line of travel so that a broad swathe of France was pillaged and devastated. Grosmont was prepared for a
set-piece battle if necessary, but was not actively seeking one. His small army arrived at Pont-Audemer after covering more than in four days. The town was close to falling, as the French had nearly succeeded in driving
mines under its walls. They fled on hearing of Grosmont's approach, abandoning their baggage and siege equipment. The English spent two days provisioning the town and filling in the French excavations. Detaching 100 men to reinforce the garrison, Grosmont marched south on 2 July. On the 4th he reached
Conches-en-Ouche, stormed it and razed it. The next day Breteuil was reached, its besiegers having retired in good order, and was resupplied sufficiently to stand a siege for a year.
Meanwhile, John had left Chartres with a large force, initially establishing himself at

with their families and valuables. The historian
Alfred Burne hypothesises that French siege equipment had been captured at Pont-Audemer and made storming fortified places a more viable proposition than earlier in the , when they were avoided. In any event, the keep was assaulted; many English are recorded as being wounded, but none were killed. At 6:00 am on the 6th its defenders negotiated a surrender: they were permitted to leave, but on condition they abandon all of their possessions. These were looted and the keep was then demolished. The attack on Verneuil was probably motivated by the prospect of looting a rich town; no attempt was made to relieve Navarrese-held Tillières-sur-Avre, to the east.

By the time the demolition of the keep at Verneuil was complete, on the evening of 6 July, reports on the approach of the French army were being received. It was much stronger than the English force; Rogers describes it as "vastly superior ... in numbers" with perhaps ten times the number of men. It had moved to
Condé-sur-Iton from Rouen and so was from the freshly provisioned Breteuil and only from Verneuil. On the 7th Grosmont rested his men and horses, but they did so in battle order outside Verneuil in case of a French attack. The French at Condé-sur-Iton also rested, having marched hard to get there in two days from Rouen; John probably also wished for all of his stragglers and detachments to join his army before offering battle. On the 8th the English marched west to

The English returned to Montebourg on 13 July. In 22 days the English had travelled , a remarkable effort for the period. The three-week expedition had been very successful: two of the besieged towns had been resupplied, the participants had seized a large amount of loot, including many horses, damage had been done to the French economy and prestige, the alliance with the Norman nobles had been cemented, there had been few casualties and the French King had been distracted from the Black Prince's preparations for a greater in south-west France.

Death and burial
After returning to England in November 1360, he fell ill early the next year, and died at
Leicester Castle on 23 March 1361. It is possible that the cause of death was the
plague, which that year was making a second visitation to England. Mortimer argues against the plague being the cause of death, as Grosmont made his will ten days before his death, a space of time inconsistent with the usual swift progress of the plague and his illness and death in early 1361 is inconsistent with reports of the spread of plague in England beginning in May. He was buried in the
Church of the Annunciation of Our Lady of the Newarke, Leicester, which he had built within the religious and charitable institution founded by his father next to Leicester Castle, and where he had reburied his father some years previously.
By the time of his death, Grosmont had participated in 15 military missions, leading 6 of them; been the King's lieutenant 7 times; led 6 significant embassies; and taken part in 12 truce conferences. A chronicler writing thirty-five years after his death described him as "one of the best warriors in the world".
