Raid on Diwrnach's cauldron

The Raid on Diwrnach's cauldron turns a failed diplomatic request into a violent seizure: Arthur secures the vessel not through Odgar son of Aedd’s authority, but by entering Diwrnach Wyddel’s house with a small retinue and taking it by force. The episode moves from command, to refusal, to armed action, and ends with the cauldron carried out of Ireland during Arthur’s campaigns.

The embassy and the refusal

Arthur first sent an embassy to Odgar son of Aedd, king of Ireland during Arthur’s campaigns, asking for the cauldron belonging to Diwrnach Wyddel, Odgar’s purveyor. Odgar commanded Diwrnach to give it up. The order establishes that Arthur’s request had the king’s support, but it did not settle who controlled the object: Diwrnach refused, declaring, "Heaven is my witness, if it would avail him anything even to look at it, he should not do so." The embassy returned without the cauldron.

Arthur then crossed to Ireland in Prydwen with a small retinue. The party went directly into Diwrnach’s house and ate and drank as much as they wished before Arthur demanded the cauldron. Diwrnach’s answer again placed the issue in terms of authority: "If I would have given it to any one, I would have given it at the word of Odgar king of Ireland." His words invoke Odgar’s command even as his refusal defies it. The request has thus passed from a royal order and an embassy to a face-to-face confrontation inside the purveyor’s house.

Seizure inside Diwrnach’s house

After Diwrnach denied Arthur’s demand, Bedwyr rose and seized the cauldron. He placed it on the back of Hygwyd, Arthur’s servant, whose regular office was to carry Arthur’s cauldron and set fire beneath it. The text also identifies Hygwyd as Cachamwri’s maternal brother; Cachamwri, like Hygwyd, served Arthur. This practical detail makes the removal possible: the vessel is not simply claimed, but immediately entrusted to the person whose household duty fits its transport.

At the same moment, Llenlleawg Wyddel seized Caledvwlch and brandished it. He and the others killed Diwrnach Wyddel and his company. The Irish then fought against Arthur’s men, but Arthur put them to flight. The taking of the cauldron is therefore inseparable from the killing that secures it: Diwrnach’s refusal is answered not by another negotiation, but by Bedwyr’s grasp, Llenlleawg’s weapon, and the defeat of the ensuing resistance.

The cauldron carried away

Arthur and his men returned to Prydwen with the cauldron, which was full of Irish money. They disembarked at the house of Llwydden son of Kelcoed, at Porth Kerddin in Dyved. The episode closes on possession and transport: the object denied to Arthur through both embassy and direct demand has been carried out of Ireland and brought to Dyved. The mention of the money also fixes the cauldron’s contents at the moment of its removal, rather than leaving its value or use abstract.

The sequence sharply contrasts Odgar’s command with Diwrnach’s actual control of the cauldron. Although the king ordered its surrender, the embassy could not enforce that order; Arthur’s small party succeeds only after entering the house and overcoming its defenders. The cauldron’s transfer is presented as a concrete outcome of force, marked by the deaths of Diwrnach and his company and the Irish resistance that follows.
