Brân, king of the island of Britain, literally lost his head during a raid to seize the Irish king's Cauldron of Rebirth.
At the end of each day's battle you dropped your dead men into the kettle, and by dawn they'd be alive again.
Putin tells us "we have a huge human resource."
Yet, Russia lost 75,000 souls on taking Bakhmut, just 0.006 of Ukraine. To conquer all of Ukraine at that rate of loss either Putin needs 5 trillion soldiers, or the biggest Cauldron of Rebirth the world has yet seen.
Brân's head is buried in London, facing France. As long as it's buried there, it was prophesied the French would never invade the island of Britain.
And, yet, with the Norman Conquest, the French returned.
Like Brân Putin lost all in his hunt for the Cauldron of Rebirth.
