They communicated their design to Eustace, count of Boulogne Roger, earl of Shrewsbury and Arundel, Robert de Belesme, his eldest son, William, bishop of Durham, Robert de Moubray, Roger Bigod, Hugh de Grentmesnil; and they easily procured the assent of these potent noblemen.

The conspirators, retiring to their castles, hastened to put themselves in a military posture; and expecting to be soon supported by a powerful army from Normandy, they had already begun hostilities in many places.
The king, sensible of his perilous situation, endeavored to engage the affections of the native English, As that people were now so thoroughly subdued that they no longer aspired to the recovery of their ancient liberties, and were content with the prospect of some mitigation in ihe tyranny of the Norman princes, they zealously embraced William's cause, upon receiving general promises of good treatment, and of enjoying the license of hunting in the royal forests.

The king was soon in a situation to take the field; and as he knew the danger of delay, he suddenly marched into Kent, where his uncles had already seized the fortresses of Pevensey and Rochester.

These places he successively reduced by famine; and though he was prevailed on by the earl of Chester, William de Warrenne, and Robert Fitz-Hammon, who had embraced his cause, to spare the lives of the rebels, he confiscated all their estates, and banished them the kingdom.[*] This success gave authority to his negotiations with Roger, earl of Shewsbury, whom he detached from the confederates; and as his powerful fleet, joined to the indolent conduct of Robert, prevented the arrival of the Norman succors, all the other rebels found no resource but in flight or submission.

Some of them received a pardon; but the greater part were attainted; and the king bestowed their estates on the Norman barons who had remained faithful to him.
