Initial phase of the war (1139–1140) The Angevin invasion finally arrived in 1139. Baldwin de Redvers crossed over from Normandy to
Wareham in August in an initial attempt to capture a port to receive the Empress Matilda's invading army, but Stephen's forces forced him to retreat into the south-west. The following month, however, Henry I's widow, Adeliza, invited the Empress to land at
Arundel instead, and on 30 September the Empress and Robert of Gloucester arrived in England with 140 knights. Stephen promptly moved south, besieging Arundel and trapping Matilda inside the castle. Stephen then agreed to a truce proposed by his brother Henry; the full details of the truce are not known, but the results were that Stephen first released Matilda from the siege and then allowed her and her household of knights to be escorted to the south-west, where they were reunited with Robert. Another theory is that Stephen released Matilda out of a sense of
chivalry; he was certainly known for having a generous, courteous personality and women were not normally expected to be targeted in Anglo-Norman warfare. Having released the Empress, Stephen focused on pacifying the south-west of England. Although there had been few new defections to the Empress, his enemies now controlled a compact block of territory stretching out from Gloucester and Bristol south-west into Devon and Cornwall, west into the Welsh Marches and east as far as Oxford and Wallingford, threatening London. Stephen started by attacking
Wallingford Castle, held by the Empress's childhood friend
Brien FitzCount, only to find it too well defended. He then left behind some forces to blockade the castle and continued west into Wiltshire to attack
Trowbridge Castle, taking the castles of
South Cerney and
Malmesbury en route. Meanwhile, Miles of Gloucester marched east, attacking Stephen's rearguard forces at Wallingford and threatening an advance on London. Stephen was forced to give up his western campaign, returning east to stabilise the situation and protect his capital. At the start of 1140, Nigel, Bishop of Ely, whose castles Stephen had confiscated the previous year, rebelled against Stephen as well. Nigel escaped to Gloucester, but his men and castle were captured, and order was temporarily restored in the east. In an effort to negotiate a truce, Henry of Blois held a peace conference at
Bath, to which Stephen sent his wife. The conference collapsed over the insistence by Henry and the clergy that they should set the terms of any peace deal, which Stephen found unacceptable.
Ranulf of Chester remained upset over Stephen's gift of the north of England to Prince Henry. Ranulf devised a plan for dealing with the problem by ambushing Henry whilst the prince was travelling back from Stephen's court to Scotland after Christmas. Stephen marched north to Lincoln and agreed to a truce with Ranulf, probably to keep him from joining the Empress's faction, under which Ranulf would be allowed to keep the castle. Stephen returned to London but received news that Ranulf, his brother and their family were relaxing in Lincoln Castle with a minimal guard force, a ripe target for a surprise attack of his own. When the news reached Stephen, he held a council to decide whether to give battle or to withdraw and gather additional soldiers: Stephen decided to fight, resulting in the
Battle of Lincoln on 2 February 1141. Robert and Ranulf's forces had superiority in cavalry and Stephen dismounted many of his own knights to form a solid infantry block; he joined them himself, fighting on foot in the battle. After an initial success in which William's forces destroyed the Angevins' Welsh infantry, the battle went badly for Stephen. Robert and Ranulf's cavalry encircled Stephen's centre, and the King found himself surrounded by the enemy army. Finally, he was overwhelmed by Robert's men and taken away from the field in custody. He was initially left confined in relatively good conditions, but his security was later tightened and he was kept in chains. Bishop Henry summoned a council at
Winchester before Easter in his capacity as papal legate to consider the clergy's view. He had made a private deal with the Empress Matilda that he would deliver the support of the church, if she agreed to give him control over church business in England. Henry handed over the royal treasury, rather depleted except for Stephen's crown, to the Empress, and
excommunicated many of Stephen's supporters who refused to switch sides. Archbishop Theobald of Canterbury was unwilling to declare Matilda queen so rapidly, however, and a delegation of clergy and nobles, headed by Theobald, travelled to see Stephen in Bristol and consult about their moral dilemma: should they abandon their oaths of fealty to the King? When Matilda advanced to London in an effort to stage her coronation in June, though, she faced an uprising by the local citizens in support of Stephen that forced her to flee to Oxford, uncrowned. Once news of Stephen's capture reached him, Geoffrey of Anjou invaded Normandy again and, in the absence of Waleran de Beaumont, who was still fighting in England, Geoffrey took all the duchy south of the river
Seine and east of the river
Risle. No help was forthcoming from Stephen's brother Theobald this time either, who appears to have been preoccupied with his own problems with France—the new French king,
Louis VII, had rejected his father's regional alliance, improving relations with Anjou and taking a more bellicose line with Theobald, which would result in war the following year. Geoffrey's success in Normandy and Stephen's weakness in England began to influence the loyalty of many Anglo-Norman barons, who feared losing their lands in England to Robert and the Empress, and their possessions in Normandy to Geoffrey. Many started to leave Stephen's faction. Waleran de Beaumont was one of those who decided to defect in mid-1141, crossing into Normandy to secure his ancestral possessions by allying himself with the Angevins, and bringing Worcestershire into the Empress's camp. Waleran's twin brother, Robert, effectively withdrew from fighting in the conflict at the same time. Other supporters of the Empress were restored in their former strongholds, such as Bishop Nigel of Ely, or received new earldoms in the west of England. The royal control over the
minting of coins broke down, leading to coins being struck by local barons and bishops across the country. , where Stephen almost captured the Empress Matilda Stephen's wife, Matilda, played a critical part in keeping the King's cause alive during his captivity. Queen Matilda gathered Stephen's remaining lieutenants around her and the royal family in the south-east, advancing into London when the population rejected the Empress. Stephen's long-standing commander William of Ypres remained with the Queen in London; William Martel, the royal steward, commanded operations from
Sherborne in Dorset, and Faramus of Boulogne ran the royal household. The Queen appears to have generated genuine sympathy and support from Stephen's more loyal followers. The King's eventual release resulted from the Angevin defeat at the
Rout of Winchester. Robert of Gloucester and the Empress besieged Henry in the city of Winchester in July. Queen Matilda and William of Ypres then encircled the Angevin forces with their own army, reinforced with fresh troops from London. Further negotiations attempted to deliver a general peace agreement but the Queen was unwilling to offer any compromise to the Empress, and Robert refused to accept any offer to encourage him to change sides to Stephen. Stephen began re-establishing his authority. Possibly this illness was the result of his imprisonment the previous year, but he finally recovered and travelled north to raise new forces and to successfully convince Ranulf of Chester to change sides once again. Stephen then spent the summer attacking some of the new Angevin castles built the previous year, including
Cirencester,
Bampton and
Wareham. In September, he spotted an opportunity to seize the Empress Matilda herself in
Oxford. Once on the other side, the King and his men stormed into the town, trapping the Empress in the castle.
Stalemate (1143–1146) The war between the two sides in England reached a stalemate in the mid-1140s, while Geoffrey of Anjou consolidated his hold on power in Normandy. 1143 started precariously for Stephen when he was besieged by Robert of Gloucester at
Wilton Castle, an assembly point for royal forces in
Herefordshire. Stephen attempted to break out and escape, resulting in the
battle of Wilton. Once again, the Angevin cavalry proved too strong, and for a moment it appeared that Stephen might be captured for a second time. On this occasion, however,
William Martel, Stephen's steward, made a fierce rear guard effort, allowing Stephen to escape from the battlefield. In late 1143, Stephen faced a new threat in the east, when
Geoffrey de Mandeville, Earl of Essex, rose up in rebellion against him in East Anglia. The King had disliked the Earl for several years, and provoked the conflict by summoning Geoffrey to court, where the King arrested him. Geoffrey gave in, but once free he headed north-east into the Fens to the Isle of Ely, from where he began a military campaign against
Cambridge, with the intention of progressing south towards London. With all of his other problems and with
Hugh Bigod, 1st Earl of Norfolk, in open revolt in
Norfolk, Stephen lacked the resources to track Geoffrey down in the Fens and made do with building a screen of castles between Ely and London, including
Burwell Castle. For a period, the situation continued to worsen. Ranulf of Chester revolted once again in the summer of 1144, splitting up Stephen's
Honour of Lancaster between himself and Prince Henry. In the west, Robert of Gloucester and his followers continued to raid the surrounding royalist territories, and Wallingford Castle remained a secure Angevin stronghold, too close to London for comfort. By this point in the war, Stephen was depending increasingly on his immediate royal household, such as William of Ypres and others, and lacked the support of the major barons who might have been able to provide him with significant additional forces; after the events of 1141, Stephen made little use of his network of earls. After 1143 the war ground on, but progressing slightly better for Stephen. Miles of Gloucester, one of the most talented Angevin commanders, had died whilst hunting over the previous Christmas, relieving some of the pressure in the west. Geoffrey de Mandeville's rebellion continued until September 1144, when he died during an attack on Burwell. The war in the west progressed better in 1145, with the King recapturing
Faringdon Castle in Oxfordshire.
Final phases of the war (1147–1152) and his wife,
Eleanor of Aquitaine England had suffered extensively from the war by 1147, leading later Victorian historians to call the period of conflict "
the Anarchy". The contemporary
Anglo-Saxon Chronicle recorded how "there was nothing but disturbance and wickedness and robbery". Certainly in many parts of the country, such as
Wiltshire, Berkshire, the
Thames Valley and
East Anglia, the fighting and raiding had caused serious devastation. Numerous "
adulterine", or unauthorised, castles had been built as bases for local lords — the chronicler
Robert of Torigny complained that as many as 1,115 such castles had been built during the conflict, although this was probably an exaggeration as elsewhere he suggested an alternative figure of 126. The previously centralised royal coinage system was fragmented, with Stephen, the Empress and local lords all minting their own coins. Some parts of the country, though, were barely touched by the conflict—for example, Stephen's lands in the south-east and the Angevin heartlands around Gloucester and Bristol were largely unaffected, and David I ruled his territories in the north of England effectively. With Stephen often based in the south-east, increasingly
Westminster, rather than the older site of
Winchester, was used as the centre of royal government. The character of the conflict in England gradually began to shift; as historian Frank Barlow suggests, by the late 1140s "the civil war was over", barring the occasional outbreak of fighting. In 1147 Robert of Gloucester died peacefully, and the next year the Empress Matilda left south-west England for Normandy, both of which contributed to reducing the tempo of the war.
Henry FitzEmpress, the eldest son of the Empress Matilda, mounted a small mercenary invasion of England in 1147 but the expedition failed, not least because Henry lacked the funds to pay his men. Henry FitzEmpress returned to England again in 1149, this time planning to form a northern alliance with Ranulf of Chester. The Angevin plan involved Ranulf agreeing to give up his claim to
Carlisle, held by the Scots, in return for being given the rights to the whole of the Honour of Lancaster; Ranulf would give homage to both David and Henry, with Henry having seniority. Following this peace agreement, Henry and Ranulf agreed to attack
York, probably with help from the Scots. Stephen marched rapidly north to York and the planned attack disintegrated, leaving Henry to return to Normandy, where he was declared duke by his father. Although still young, Henry was increasingly gaining a reputation as an energetic and capable leader. His prestige and power increased further when he unexpectedly married the attractive
Eleanor, Duchess of Aquitaine, the recently divorced wife of Louis VII, in 1152. The marriage made Henry the future ruler of a huge swathe of territory across France. In the final years of the war, Stephen began to focus on the issue of his family and the succession. He wanted to confirm his eldest son,
Eustace, as his successor, although chroniclers recorded that Eustace was infamous for levying heavy taxes and extorting money from those on his lands. Stephen's second son,
William, was married to the extremely wealthy heiress
Isabel de Warenne, Countess of Surrey. In 1148, Stephen built the
Cluniac Faversham Abbey as a resting place for his family. Both Stephen's wife, Matilda, and his brother Theobald died in 1152.
Argument with the church (1145–1152) , with whom Stephen argued over ecclesiastical policy Stephen's relationship with the church deteriorated badly towards the end of his reign. The reforming movement within the church, which advocated greater autonomy from royal authority for the clergy, had continued to grow, while new voices such as the Cistercians had gained additional prestige within the monastic orders, eclipsing older orders such as the Cluniacs. The row between Henry and Bernard grew increasingly personal, and Henry used his authority as legate to appoint his nephew
William of York to the post in 1141 only to find that, when
Pope Innocent II died in 1143, Bernard was able to get the appointment rejected by Rome. Bernard then convinced
Pope Eugene III to overturn Henry's decision altogether in 1147, deposing William, and appointing
Henry Murdac as archbishop instead. Stephen was furious over what he saw as potentially precedent-setting papal interference in his royal authority and initially refused to allow Murdac into England. When Theobald, the Archbishop of Canterbury, went to consult with the Pope on the matter against Stephen's wishes, the King refused to allow him back into England either and seized his estates. Nonetheless, the pressure on Stephen to get Eustace confirmed as his legitimate heir continued to grow. The King gave Eustace the County of Boulogne in 1147, but it remained unclear whether Eustace would inherit England. Stephen's preferred option was to have Eustace crowned while he himself was still alive, as was the custom in France, but this was not the normal practice in England, and
Celestine II, during his brief tenure as pope between 1143 and 1144, had banned any change to this practice. Stephen then made a fresh attempt to have Eustace crowned at Easter 1152, gathering his nobles to swear fealty to Eustace, and then insisting that Theobald and his bishops anoint him king. When Theobald refused yet again, Stephen and Eustace imprisoned both him and the bishops and refused to release them unless they agreed to crown Eustace. Stephen's castle at
Malmesbury was besieged by Henry's forces, and the King responded by marching west with an army to relieve it. He unsuccessfully attempted to force Henry's smaller army to fight a decisive battle along the
river Avon. Over the summer, Stephen intensified the long-running siege of
Wallingford Castle in a final attempt to take this major Angevin stronghold. The fall of Wallingford appeared imminent and Henry marched south in an attempt to relieve the siege, arriving with a small army and placing Stephen's besieging forces under siege themselves. Upon news of this, Stephen gathered up a large force and marched from Oxford, and the two sides confronted each other across the
River Thames at Wallingford in July. As a result, instead of a battle ensuing, members of the church
brokered a truce, to the annoyance of both Stephen and Henry. Eustace's death removed an obvious claimant to the throne and was politically convenient for those seeking a permanent peace in England. It is possible, however, that Stephen had already begun to consider passing over Eustace's claim; historian Edmund King observes that Eustace's claim to the throne was not mentioned in the discussions at Wallingford, for example, and this may have added to his anger. Fighting continued after Wallingford but in a rather half-hearted fashion. Stephen lost the towns of
Oxford and
Stamford to Henry while the King was diverted fighting Hugh Bigod in the east of England, but
Nottingham Castle survived an Angevin attempt to capture it. Meanwhile, Henry of Blois and
Theobald of Canterbury were for once unified in an effort to broker a permanent peace between the two sides, putting pressure on Stephen to accept a deal. The two armies met again at Winchester, where the leaders would ratify the terms of a permanent peace in November. Stephen announced the
Treaty of Winchester in Winchester Cathedral: he recognised Henry as his adopted son and successor, in return for Henry doing
homage to him; Stephen promised to listen to Henry's advice, but retained all his royal powers; Stephen's remaining son,
William, would do homage to Henry and renounce his claim to the throne, in exchange for promises of the security of his lands; key royal castles would be held on Henry's behalf by guarantors, whilst Stephen would have access to Henry's castles; and the numerous foreign mercenaries would be demobilised and sent home. Stephen and Henry sealed the treaty with a
kiss of peace in the cathedral. == Death ==
