In addition, two knights were to come from each shire, and clergy and barons as usual--though in the case of the earls and barons only twenty-three were invited, for Simon had no desire for the presence of those who were his enemies.

The Full Parliament sat till March, and then two months later war had once more blazed out.

Earl Gilbert of Gloucester broke away from Simon, Prince Edward escaped from custody, and these two joined Lord Mortimer and the Welsh Marchers.
On August 4th Edward surprised and routed the army of the younger Simon near Kenilworth, and then advanced to crush the great Earl, who was encamped at Evesham, waiting to join forces with his son.

All hope of escape for Earl Simon was lost, and he was outnumbered by seven to two.

But fly he would not.
