While William was thus engaged in pursuing his military education in Paris, several competitors for his dukedom immediately appeared in Normandy and took the field. The strongest and most prominent among them was the Earl of Arques. His name was William too, but, to distinguish him from the young duke, we shall call him Arques. He was a brother of Robert, and maintained that, as Robert left no lawful heir, he was indisputably entitled to succeed him. Arques assembled his forces and prepared to take possession of the country.
It will be recollected that Robert, when he left Normandy in setting out on his pilgrimage, had appointed a nobleman named Alan to act as regent, or governor of the country, until he should return; or, in case he should never return, until William should become of age. Alan had a council of officers, called the council of regency, with whose aid he managed the administration of the government. This council, with Alan at their head, proclaimed young William duke, and immediately began to act in his name. When they found that the Earl of Arques was preparing to seize the government, they began to assemble their forces also, and thus both sides prepared for war.
Before they actually commenced hostilities, however, the pilgrim knights who had accompanied Robert on his pilgrimage, and who had been journeying home slowly by themselves ever since their leader's death, arrived in Normandy. These were chieftains and nobles of high rank and influence, and each of the contending parties were eager to have them join their side. Besides the actual addition of force which these men could bring to the cause they should espouse, the moral support they would give to it was a very important consideration. Their having been on this long and dangerous pilgrimage invested them with a sort of romantic and religious interest in the minds of all the people, who looked up to them, in consequence of it, with a sort of veneration and awe; and then, as they had been selected by Robert to accompany him on his pilgrimage, and had gone on the long and dangerous journey with him, continuing to attend upon him until he died, they were naturally regarded as his most faithful and confidential friends. For these and similar reasons, it was obvious that the cause which they should espouse in the approaching contest would gain a large accession of moral power by their adhesion.
