<<Syon Abbey, a monastery of the Bridgettine Order, acquired the Mount in 1424. Some 20 years later the Mount was granted by Henry VI to King's College, Cambridge on its foundation. However, when Edward IV took the throne during the Wars of the Roses the Mount was returned to the Syon Abbey in 1462.
John de Vere, 13th Earl of OXFORD, seized and held it during a siege of 23 weeks against 6,000 of Edward IV's troops in 1473–74. Perkin Warbeck, a pretender to the English throne, occupied the Mount in 1497. Sir Humphrey Arundell, Governor of St Michael's Mount, led the Prayer Book Rebellion of 1549. During the reign of Queen Elizabeth I, it was given to Robert Cecil, Earl of Salisbury, by whose son it was sold to Sir Francis Bassett.>>

According to Asimov:
<<The armies collided and fought [at Tewkesbury] on May 4, 1471.
The impetuous attack of Edward & Richard carried the day
and a number of Lancastrian leaders were taken.
According to Shakespeare, one was
OXFORD:>>

<<Opposition leaders, if taken alive, were generally executed as
traitors after the battle. Why was this not the case with
OXFORD?
It was because
OXFORD was not at Tewkesbury. He had fought well at
BARNET [3 weeks prior] and then went to France. It was not till 1473,
two years after Tewkesbury, which had been fought without him, that
he attempted a reinvasion of England and a revival of the ruined
Lancastrian cause. He was besieged in Cornwall and, after four and
a half months, was forced to surrender. Passions had lessened
by then and he was imprisoned rather than executed.
OXFORD's
imprisonment was at a Hames Castle, near Calais, for it seemed
best to keep him away from English soil proper.>> -- Asimov
