Constantine refuses, whereupon the Turkish troops desert to William. He decides to raise the siege and departs for Constantinople. He leaves Alexios Philes with a force and marches towards Messenia, where he occupies the passes, situated near Gardiki Castle. William, reinforced by the Turkish contingent, marches to Messenia to attack the Byzantines, despite their holding strong positions on the high ground. The first two attacks are beaten off, but during the third attack, the Byzantines flee in panic. Alexios, along with many Greek nobles, are captured. [1]

Battle of Lewes 1264 battle of the Second Barons War resulting in the Mise Of Lewes

The Battle of Lewes was one of two main battles of the conflict known as the Second Barons' War. It took place at Lewes in Sussex, on 14 May 1264. It marked the high point of the career of Simon de Montfort, 6th Earl of Leicester, and made him the "uncrowned King of England". Henry III left the safety of Lewes Castle and St. Pancras Priory to engage the barons in battle and was initially successful, his son Prince Edward routing part of the baronial army with a cavalry charge. However, Edward pursued his quarry off the battlefield and left Henry's men exposed. Henry was forced to launch an infantry attack up Offham Hill where he was defeated by the barons' men defending the hilltop. The royalists fled back to the castle and priory and the King was forced to sign the Mise of Lewes, ceding many of his powers to Montfort.

The Battle of Evesham was one of the two main battles of 13th century England's Second Barons' War. It marked the defeat of Simon de Montfort, Earl of Leicester, and the rebellious barons by the future King Edward I, who led the forces of his father, King Henry III. It took place on 4 August 1265, near the town of Evesham, Worcestershire.

Second Barons War 1260s civil war in England

The Second Barons' War (1264–1267) was a civil war in England between the forces of a number of barons led by Simon de Montfort against the royalist forces of King Henry III, led initially by the king himself and later by his son, the future King Edward I. The barons sought to force the king to rule with a council of barons rather than through his favourites. The war also featured a series of massacres of Jews by de Montfort's supporters including his sons Henry and Simon, in attacks aimed at seizing and destroying evidence of baronial debts. To bolster the initial success of his baronial regime, de Montfort sought to broaden the social foundations of parliament by extending the franchise to the commons for the first time. However, after a rule of just over a year, de Montfort was killed by forces loyal to the king in the Battle of Evesham.
