Wick

Here [Abson], and at Wick, Roman coins and other remains have been found; footpaths can be partly traced here, and a field, called the “Chestles, or Castles,” is still pointed out as the scene of a great battle between Ceaulin, a Saxon chieftain, and three British kings, all of whom fell beneath his sword. It took place about the year 577.

.. striking up an unfrequented-looking lane, which is paved like an old Roman road, you arrive at the Chestles field. The three monumental stones, honey-combed and moss-covered with age, rear their old heads from a sepulchral mound. The whole erection bears traces of the greatest antiquity, no inscription or chiselling being visible on their surface. The farmer to whom the field belongs is a great enemy to antiquarians, and has rendered the field, by a malicious sort of ingenuity, almost inaccessible.

I wonder what the malicious ingenuity was. *It sounds like he could be talking about Abson here, but actually the next sentence mentions the church of St Bartholomew, which is in Wick, so it seems the legend is indeed associated with the three stones.
