1284

On 26 June 1284, the Pied Piper rid the German town of Hamelin of its rats, and, when the town refused to pay him, of its children, as well. (TV: The Day of the Clown)

Shortly afterwards, the First Doctor, John and Gillian arrived and, after facing the Piper, returned the children to the village. (COMIC: Challenge of the Piper)
