The Departure of the Knights of the Round Table is the rupture that sends Arthur’s greatest fellowship out of Camelot in pursuit of the Holy Grail. The quest begins not with a battle but with a Pentecost marvel: the Grail passes through the hall unseen, and the vision turns the gathered company toward a sacred undertaking that Arthur already fears will divide it beyond repair.

The feast and the vow

At Camelot, the knights return from church to find gold letters marking places at the Round Table, including a prophecy that the Siege Perilous should be fulfilled on that day. Launcelot observes that the appointed time has arrived, and Arthur orders the seat covered until the one destined to achieve the adventure comes. Then word reaches the court of a sword fixed in a stone floating on the river, drawing the company away from the hall and toward another marvel.

The Grail’s arrival completes the day’s sequence of signs. A light brighter than ordinary daylight fills the hall; the knights seem transformed, and the covered vessel passes among them without revealing either itself or its bearer. Each receives the food and drink he most desires, yet the sacred object remains beyond sight. Once it vanishes, Gawaine makes a vow to seek the Grail for a year and a day, or longer if necessary, and not to return until he has seen it more openly. Most of the Round Table rise and take vows in turn, binding themselves to leave.

Arthur’s grief and the terms of the quest

Arthur understands the consequence before the knights depart: their vow cannot be undone, and the fellowship that has given his court its distinction will be scattered. He tells Gawaine that the promise has nearly slain him and that many of the knights will die on the quest. His distress is personal as well as political; he says that he has loved them as his own life and doubts that they will ever all meet again in the world.

Launcelot counsels him that the undertaking will bring the knights honour, but Arthur cannot take comfort in that prospect. He asks Launcelot to advise him how the quest might be undone, and Launcelot replies that the many knights who have sworn cannot simply withdraw. The exchange sets sacred obligation against the king’s attachment to the fellowship: Arthur can acknowledge the force of their vows without ceasing to mourn what obedience to them will cost his court.

The departure also has a religious restriction. As ladies and gentlewomen consider following the knights they love, Nacien the Hermit arrives in religious clothing with a warning: no woman is to accompany the quest, which he declares too sacred for such company, and a knight not clean of sin will not see the mysteries of Christ. The women remain behind. The rule gives the expedition a defined spiritual character, setting it apart from the courtly relationships that shape life at Camelot.

Leaving Camelot

After the service, the court counts the knights who have taken the vow: 150, all members of the Round Table. They put on their helmets and commend themselves to Guenever. The departure is marked by public mourning, while Guenever withdraws to her chamber so that others will not see the depth of her sorrow. Launcelot goes to her; she grieves that he is leaving her and Arthur, and he promises to return as soon as he can with honour. She, in turn, prays for his safety and that of the fellowship.

The knights ride through Camelot’s streets as rich and poor alike weep, and Arthur turns away, unable to speak through his grief. Their first stop is the castle of Vagon, whose elderly lord welcomes them. The following morning the company agrees to separate. They leave in mourning, each knight taking the road that seems best to him. The movement from a counted company to individual departures makes visible the loss Arthur anticipated: a fellowship sworn together at the feast becomes a host of solitary questers.

Consequence for the fellowship

The Grail’s appearance gives the departure its sacred occasion, but the scene also makes its cost unmistakable. Arthur’s court has been bound by shared vows and affection; now the very vow that honours the quest breaks up that community. The knights’ commitment is not presented as casual adventure: the warning about purity, the prohibition on female companions, and Arthur’s conviction that many will die place spiritual trial and separation at its centre.

The episode therefore turns Pentecost from a feast of reunion into a threshold. The knights leave Camelot in a body, but do not remain a company for long. Their separate roads begin a quest that tests each knight beyond the sustaining order of Arthur’s court, while the king is left to reckon with a fellowship he cannot hold together by affection alone.
