Second Battle of St Albans The Second Battle of St Albans was a battle of the English Wars of the Roses fought on 17 February 1461 , at St Albans . The army of the Yorkist faction under the Earl of Warwick attempted to bar the road to London north of the town . The rival Lancastrian army used a wide outflanking manoeuvre to take Warwick by surprise , cut him off from London , and drive his army from the field . The victors also released the feeble King Henry VI , who had been Warwick ' s prisoner , from his captivity . However , they ultimately failed to take advantage of their victory . Background . The Wars of the Roses were fought between the supporters of the House of Lancaster , represented by the mentally unstable King Henry VI , and those of the rival House of York . Richard of York quarrelled with several of Henry ' s court during the late 1440s and early 1450s . He was respected as a soldier and administrator , and was believed by his own supporters to have a better claim to the throne than Henry . York and his friends finally openly rebelled in 1455 . At the First Battle of St Albans , York gained a victory , but this did not resolve the causes of the conflict . After several attempts at reconciliation , fighting resumed in 1459 . At the Battle of Northampton in 1460 , Richard of York ' s nephew , the Earl of Warwick , defeated a Lancastrian army and captured King Henry , who had taken no part . York returned to London from exile in Ireland and attempted to claim the throne , but his supporters were not prepared to go so far . Instead , an agreement was reached , the Act of Accord , by which York or his heirs were to become king after Henry ' s death . This agreement disinherited Henry ' s young son Edward of Westminster . Henry ' s queen , Margaret of Anjou , refused to accept the Act of Accord and took Edward to Scotland to gain support there . York ' s rivals and enemies meanwhile raised an army in the north of England . York and his brother - in - law , the Earl of Salisbury ( Warwick ' s father ) , led an army to the north late in 1460 to counter these threats , but they drastically underestimated the Lancastrian forces . At the Battle of Wakefield , the Yorkist army was destroyed and York , Salisbury and York ' s second son , Edmund , Earl of Rutland , were killed in the fighting or were executed after the battle . Campaign . The victorious Lancastrian army began advancing south towards London . It was led by comparatively young nobles such as the Duke of Somerset , the Earl of Northumberland and Lord Clifford , whose fathers had been killed by York and Warwick at the First Battle of St Albans . The army contained a substantial contingent from the West Country , but many of its men were from the Scottish Borders or Scotland , who subsisted largely on plunder in their march south . The death of Richard of York left his eighteen - year old son Edward , Earl of March , as the Yorkist claimant for the throne . He led one Yorkist army in the Welsh Marches , while Warwick led another in London and the south east . Naturally , they intended to combine their forces to face Margaret ' s army , but Edward was delayed by the need to confront another Lancastrian army from Wales led by Jasper Tudor . On 2 February , Edward defeated Tudor ' s army at the Battle of Mortimer ' s Cross . Warwick , with the captive King Henry in his train , meanwhile moved to block Margaret ' s army ' s route to London . He took up position north of St Albans astride the main road from the north ( the ancient Roman road known as Watling Street ) , where he set up several fixed defences , including cannon and obstacles such as caltrop s and pavise s studded with spikes , and partly manned by Burgundian mercenaries equipped with handguns . Part of his defences used the ancient Belgic earthwork known as Beech Bottom Dyke . Warwick ' s forces were divided into three " Battles " , as was customary at the time . He himself led the Main Battle in the centre . The Duke of Norfolk led the Forward ( or Vaward ) Battle on the right and Warwick ' s brother John Neville commanded the Rear Battle on the left . Although strong , Warwick ' s lines faced north only . Margaret knew of Warwick ' s dispositions , probably through Sir Henry Lovelace , the steward of Warwick ' s own household . Lovelace had been captured by the Lancastrians at Wakefield but had been spared from execution and released , and he believed he had been offered the vacant Earldom of Kent as reward for betraying Warwick . Late on 16 February , Margaret ' s army swerved sharply west and captured the town of Dunstable . About 200 local people under the town butcher tried to resist them , but were easily dispersed . Warwick ' s " scourers " ( scouts and patrols and foraging parties ) failed to detect this move . Battle . From Dunstable , Margaret ' s forces moved south - east at night , towards St Albans . The leading Lancastrian forces attacked the town shortly after dawn . Storming up the hill past the Abbey , they were confronted by Yorkist archers in the town centre who shot at them from the house windows . This first attack was repulsed . As they regrouped at the ford across the River Ver , the Lancastrian commanders sought another route into the town . This was found and a second attack was launched along the line of Folly Lane and Catherine Street . This second attack met with no opposition and the Yorkist archers in the town were now outflanked . They continued to fight house to house however , and were not finally overcome for several hours . Having gained the town itself , the Lancastrians turned north towards John Neville ' s Rear Battle , positioned on Bernards Heath . In the damp conditions , many of the Yorkists ' cannon and handguns failed to fire as their powder was dampened . Warwick found it difficult to extricate his other units from their fortifications and turn them about to face the Lancastrians , so that the Yorkist battles straggled into action one by one instead of in coordinated fashion . The Rear Battle , attempting to reinforce the defenders of the town , was engaged and dispersed . The Kentish contingent in the Yorkist army under the traitor Lovelace defected at this point , causing further confusion in the Yorkist ranks . By late afternoon , the Lancastrians were attacking north - east out of St Albans to engage the Yorkist Main and Vaward battles under Warwick and Norfolk . As dusk set in ( which would have been in the very early evening at this time of year and in the poor weather ) , Warwick realised that his men were outnumbered and increasingly demoralised , and withdrew with his remaining forces ( about 4 , 000 men ) to Chipping Norton in Oxfordshire . Aftermath . As the Yorkists retreated , they left behind the bemused King Henry , who is supposed to have spent the battle sitting under a tree , singing . Two knights ( Lord Bonville and Sir Thomas Kyriell , a veteran leader of the Hundred Years War ) had sworn to let him come to no harm , and remained with him throughout . The next morning Margaret asked her son , the seven - year - old Edward of Westminster , how , not whether , the two knights were to die . Edward , thus prompted , sent them to be beheaded . John Neville had been captured but was spared execution , as the Duke of Somerset feared that his own younger brother who was in Yorkist hands might be executed in reprisal . Henry knighted the young Prince Edward , who in turn knighted thirty Lancastrian leaders . One was Andrew Trollope , an experienced captain who had deserted the Yorkists at the Battle of Ludford Bridge in 1459 and who was reckoned by many to have planned the Lancastrian victories at Wakefield and Saint Albans . At Saint Albans , he had injured his foot stepping on one of Warwick ' s caltrops , but he nevertheless claimed to have killed fifteen Yorkists . Although Margaret and her army could now march unopposed on to London , they did not do so . The Lancastrian army ' s reputation for pillage caused the Londoners to bar the gates . This in turn caused Margaret to hesitate , as did the news of Edward of March ' s victory at Mortimer ' s Cross . The Lancastrians fell back through Dunstable , losing many Scots and Borderers who deserted and returned home with the plunder they had already gathered . Edward of March and Warwick entered London on 2 March , and Edward was quickly proclaimed King Edward IV of England . Within a few weeks he had confirmed his hold on the throne with a decisive victory at the Battle of Towton . Perhaps the most significant person to be killed at the battle of Saint Albans , at least in terms of its dynastic results , was John Grey of Groby , whose widow Elizabeth Woodville became the queen of Edward IV in 1464 . 550th Anniversary commemoration . On 26 & 27 February 2011 to commemorate the 550th anniversary year of the battle the Battlefields Trust hosted a conference on the battle , close to the battle site . This featured authentic recreations from The Medieval Siege Society , with a guided tour of the battlefield , and culminated in a Requiem Mass for the fallen at St Saviours Church conducted by Father Peter Wadsworth .
