Morgan le Fay’s Theft of Excalibur’s Scabbard is a pursuit episode in which Morgan, grieving the death of Accolon and fearing Arthur’s return, takes the protective scabbard from her sleeping brother. When Arthur follows, she casts the precious object into a lake and escapes recognition through enchantment; he returns without recovering it. The episode converts Morgan’s private loss into a lasting material consequence for Arthur: the scabbard is gone, while the sword remains in his hand.

Background and Motive

The episode begins with news reaching Morgan that Accolon has died and that Arthur has recovered his sword. She is overwhelmed by sorrow, but conceals it rather than letting it show. She expects that when Arthur arrives, her own life will be in danger. The account establishes the immediate circumstances of the theft: the death of Accolon, Arthur’s recovery of the weapon, and Morgan’s fear of what her brother may do.

Rather than wait for Arthur, Morgan asks Queen Guenever for leave to ride into the country, claiming that urgent news will not let her tarry. Guenever suggests she wait until the king comes home, but permits her to depart when she insists. Morgan leaves before daybreak and rides through the day and much of the night, reaching the abbey where Arthur is resting by noon. Her request to Guenever creates the opening for a covert visit, while the urgency of her journey carries the threat forward before Arthur knows she is near.

The Theft at the Abbey

At the abbey, Morgan learns that Arthur has had little rest for three nights and is asleep in bed. She orders the nuns not to wake him until she does, and they do not disobey her. She goes directly to his chamber and finds him asleep with Excalibur, naked, in his right hand. The arrangement defeats her first aim: she cannot take the sword without waking him, and she believes that if she wakes him she will be killed.

Morgan therefore takes the scabbard instead, concealing it beneath her mantle, and rides away. Arthur wakes, notices its absence, and asks who has entered his chamber. The nuns identify his sister and explain that she has gone with the scabbard. His rebuke of their failure to guard him is met with their explanation that they dared not disobey her command. The theft succeeds not through a struggle over the sword but through the difference between the weapon Arthur holds and the valuable object Morgan can remove without disturbing him.

Pursuit and Enchanted Escape

Arthur immediately orders that the best available horse be brought and tells Sir Ontzlake to arm himself in haste. The two ride after Morgan. At a cross they question a cowherd, who reports that a lady with forty horses passed that way and rode toward the forest. The report gives Arthur a direction to follow, and soon he sees Morgan ahead of him.

Morgan rides faster through the forest and reaches a plain beside a lake. Realizing that she cannot escape on horseback, she throws the scabbard into the deepest water, where its weight of gold and precious stones carries it down. She then rides into a valley of great stones. As Arthur and Ontzlake close in, she uses enchantment to transform herself, her horse, and her men into the likeness of a great marble stone. Arthur cannot distinguish his sister and her company from one another or identify them among the stones. He interprets the turn of events as divine vengeance and regrets the misadventure, but the scabbard is nowhere to be found.

Outcome and Narrative Significance

After Arthur rides back to the abbey, Morgan and her companions return to their former shapes and depart wherever they choose. The pursuit ends without capture, reconciliation, or recovery of the stolen object. The scabbard’s disappearance is the decisive consequence: Morgan cannot take Excalibur from Arthur, but she removes its sheath from his possession and makes sure he cannot retrieve it.

The episode binds personal conflict to an object with a conspicuous material presence. The scabbard is heavy with gold and precious stones, yet its value does not protect it from being lost beneath the lake; its concealment becomes the means by which Morgan escapes. The account presents Arthur’s failure to recognize the enchanted stone as the final reversal of the chase: he reaches the place where Morgan has hidden herself, but cannot see her there. The theft thus ends not with a victory in combat, but with an unresolved loss that sends Arthur back to the abbey without the scabbard.
