Tintagil Execution Incident

Tintagil’s execution episode is a sequence of accusation, attempted judgment, and escape that shows how King Mark’s hostility toward Sir Tristram turns the court’s public scandal into a personal pursuit. A sorcerous horn first brings King Mark’s queen, La Beale Isoud, under suspicion; Sir Andred then catches Sir Tristram with her, and the king’s party takes him toward judgment. Sir Tristram escapes the immediate threat, but not the consequences: King Mark recaptures La Beale Isoud, and the lovers are separated while Sir Tristram is left to recover from an envenomed arrow wound.

The horn and the court’s accusation

Sir Lamorak forces a messenger to carry a gold-mounted horn to King Mark. The horn is said to distinguish a wife faithful to her husband from one who is not: a faithful drinker can drink without spilling, while an unfaithful one spills the drink. Sir Lamorak sends it in spite of Queen Guenever and Sir Launcelot, but directs the messenger to present it to King Mark as a test of his own queen, La Beale Isoud.

King Mark makes La Beale Isoud and one hundred other ladies drink from the horn. Only four drink cleanly. He responds by swearing that the queen and the other women should be burned, but the barons refuse to accept the horn’s result as grounds for punishment. They call it a product of sorcery, condemn its use as a cause of strife, and denounce Morgan le Fay, who sent it. Their resistance blocks the proposed punishment, but the episode leaves the court divided and Sir Tristram furious with Sir Lamorak for using the test to spite him.

Sir Andred’s ambush and the threatened judgment

Sir Andred, Sir Tristram’s cousin, watches him closely and eventually chooses a moment to act. He gathers twelve knights and surprises Sir Tristram while he is with La Beale Isoud. They bind Sir Tristram and keep him until the following day. With King Mark, Sir Andred, and some of the barons consenting, he is then led under guard toward a chapel on the sea rocks, where judgment awaits.

Sir Tristram appeals to the knights’ sense of honor by recalling what he has done for Cornwall. When he fought Sir Marhaus over Cornwall’s tribute, he says, the country had promised him a better reward; he argues that letting him die in this fashion would disgrace knighthood. Sir Andred rejects the appeal and calls him a traitor. Sir Tristram answers that Andred is his kinsman and would not dare put him to death if the two stood alone. Andred draws his sword, making the threatened judgment immediate.

Escape from the chapel and rescue from the rocks

Although his hands are bound to two knights, Sir Tristram pulls them together and frees himself. He takes Sir Andred’s sword, knocks his cousin down, and fights until ten of the knights are dead. He then holds the chapel, but a crowd of more than a hundred gathers against him. Recognizing that he is without armor and cannot face the gathering force, he shuts the chapel door, breaks the bars of a window, and leaps out onto the sea crags. Sir Andred and his followers cannot reach him there at that time.

Sir Tristram’s men—Gouvernail, Sir Lambegus, and Sir Sentraille de Lushon—search for their master. When they find him on the rocks, they pull him up with towels. His escape has prevented his immediate condemnation, but it has not secured La Beale Isoud’s safety. Sir Tristram asks where she is and learns that she has been put in a lazar-cote. He gathers his men, takes her away, and brings her to a manor in the forest.

Separation and aftermath

Sir Tristram tells his men to leave him, with Gouvernail remaining. While Sir Tristram is asleep in the forest, a man whose brother he had previously killed shoots him through the shoulder with an arrow; Sir Tristram wakes and kills the attacker. By then, word has reached King Mark that Sir Tristram and La Beale Isoud are at the manor. The king arrives with many knights, but Sir Tristram has already gone. King Mark takes La Beale Isoud home and keeps her under strict guard, preventing either lover from sending word to the other.

When Sir Tristram returns toward the manor, he finds the tracks of many horses and realizes that La Beale Isoud has been taken. His grief is prolonged by the arrow wound, which is envenomed. Through La Beale Isoud’s message, delivered by a lady related to Dame Bragwaine, he learns that she cannot heal him and that he should go to King Howel in Brittany, whose daughter Isoud la Blanche Mains can help. Sir Tristram and Gouvernail sail there; King Howel welcomes him, and Isoud la Blanche Mains heals him. The escape from King Mark’s immediate judgment thus leads not to reunion, but to enforced separation and a journey abroad for care.
