At last in 1079 Philip gave Robert a settled dwelling-place in the border-fortress of Gerberoi. The strife between father and son became dangerous. William besieged the castle, to undergo before its walls his second defeat, to receive his first wound, and that at the hands of his own son. Pierced in the hand by the lance of Robert, his horse smitten by an arrow, the Conqueror fell to the ground, and was saved only by an Englishman, Tokig, son of Wiggod of Wallingford, who gave his life for his king. It seems an early softening of the tale which says that Robert dismounted and craved his father’s pardon; it seems a later hardening which says that William pronounced a curse on his son. William Rufus too, known as yet only as the dutiful son of his father, was wounded in his defence. The blow was not only grievous to William’s feelings as a father; it was a serious military defeat. The two wounded Williams and the rest of the besiegers escaped how they might, and the siege of Gerberoi was raised.
We next find the wise men of Normandy debating how to make peace between father and son. In the course of the year 1080 a peace was patched up, and a more honourable sphere was found for Robert’s energies in an expedition into Scotland. In the autumn of the year of Gerberoi Malcolm had made another wasting inroad into Northumberland. With the King absent and Northumberland in confusion through the death of Walcher, this wrong went unavenged till the autumn of 1080. Robert gained no special glory in Scotland; a second quarrel with his father followed, and Robert remained a banished man during the last seven years of William’s reign.
