The Roman historian Tacitus wrote about Boudica fifty years after her death. He said that the British rebels: 'hastened to murder, hang, burn and crucify... up to 70,000 citizens and loyal Romanized Britons'. He also wrote that Boudica fled from the battlefield. He did not record where she was buried. There are several places in Essex that claim to be the 'traditional' place of her burial.
In 1937 an expert on mythology and Celtic folklore, Lewis Spence, wrote a book called Boadicea, Warrior Queen of the Britons. He used very uncertain evidence, which historians now do not believe. Spence concluded that the battle took place in the valley where King's Cross and St Pancras stations now stand. He even drew a map showing the positions of the British and Roman troops! However, he never suggested that Boudica was buried on the site.
