The Battle of Blore Heath was one of the first major battles in the English Wars of the Roses. It was fought on 23 September 1459, at Blore Heath in Staffordshire. Blore Heath itself is a sparsely populated area of farmland, two miles east of the town of Market Drayton in Shropshire, and close to the towns of Market Drayton and Loggerheads, Staffordshire.
After the First Battle of St Albans in 1455, an uneasy peace held in England. Attempts at reconciliation between the houses of Lancaster and York enjoyed but marginal success. However, both sides became increasingly wary of each other and by 1459 were actively recruiting armed supporters. Queen Margaret of Anjou continued to raise support for King Henry VI amongst noblemen, distributing an emblem of a silver swan to knights and squires enlisted by her personally, whilst the Yorkist command under the Duke of York was finding plenty of anti-royal support despite the severe punishment for raising arms against the king.
The Yorkist force based at Middleham Castle in Yorkshire (led by the Earl of Salisbury) needed to link up with the main Yorkist army at Ludlow Castle in Shropshire. As Salisbury marched south-west through the Midlands the queen ordered Lord Audley to intercept them.

Audley chose the barren heathland of Blore Heath to set up an ambush. On the morning of 23 September 1459 (Saint Thecla's day), a force of some 10,000 men took up a defensive position behind a 'great hedge' on the south-western edge of Blore Heath facing the direction of Newcastle-under-Lyme to the north-east, the direction from which Salisbury was approaching.
Yorkist scouts spotted Lancastrian banners over the top of a hedge and immediately warned Salisbury. As they emerged from the woodland, the Yorkist force of some 5,000 men realized that a much larger enemy force was awaiting their arrival. Salisbury, instead of disbanding or withdrawing his army, immediately arranged his troops into battle order, just out of range of the Lancastrian archers. To secure his right flank, he arranged the supply wagons in a defensive laager, a circular formation to provide cover to the men. Fearing a rout, Yorkist soldiers are reported to have kissed the ground beneath them, supposing that this would be the ground on which they would meet their deaths.
The two armies were separated by about 300 metres on the barren heathland. A steep-sided, wide and fast-flowing brook ran between them. The brook made Audley's position seemingly impenetrable.
Initially, both leaders sought unsuccessfully to parley in an attempt to avoid bloodshed. In keeping with many late medieval battles, the conflict opened with an archery duel between the longbows of both armies. At Blore Heath, this proved inconclusive because of the distance between the two sides.
Salisbury, aware that any attack across the brook would be suicidal, employed a ruse to encourage the enemy to attack him. He withdrew some of his middle-order just far enough that the Lancastrians believed them to be retreating. The Lancastrians launched a cavalry charge. After they had committed themselves, Salisbury ordered his men to turn back and catch the Lancastrians as they attempted to cross the brook. It is possible that the order for this Lancastrian charge was not given by Audley but it had the effect of turning the balance in favour of Salisbury. The charge resulted in heavy casualties for the Lancastrians.
The Lancastrians withdrew, and then made a second assault, possibly attempting to rescue casualties. This second attack was more successful with many Lancastrians crossing the brook. This led to a period of intense fighting in which Audley himself was killed, possibly by Sir Roger Kynaston of Myddle and Hordley.
The Earl of Salisbury, which knew the sleights, strategies and policies of warlike affairs, suddenly returned, and shortly encountered with the Lord Audley and his chief captains, ere the residue of his army could pass the water. The fight was sore and dreadful. The earl desiring the saving of his life, and his adversaries coveting his destruction, fought sore for the obtaining of their purpose, but in conclusion, the earl's army, as men desperate of aid and succour, so eagerly fought, that they slew the Lord Audley, and all his captains, and discomfited all the remnant of his people... 
The death of Audley meant that Lancastrian command fell to the second-in-command, Lord Dudley, who ordered an attack on foot with some 4,000 men. As this attack also failed, some 500 Lancastrians joined the enemy and began attacking their own side. At this point, all remaining Lancastrian resistance collapsed and the Yorkists had only to advance to complete the rout.
The rout continued through the night, with the Yorkists pursuing the fleeing enemy for miles across the countryside.
Salisbury was concerned that Lancastrian reinforcements were in the vicinity and was keen to press on southwards towards Ludlow. He made his camp on a hillside by Market Drayton that later took the name Salisbury Hill. He employed a local friar to remain on Blore Heath throughout the night and to periodically discharge a cannon in order to deceive any Lancastrians nearby into believing that the fight was continuing.
The battle was commemorated by a re-enactment each year in September at Blore Heath until 2009.
