Overview: Episode two sees our intrepid River Hunters visit the River Avon beneath the medieval Warwick Castle. Synonymous with Shakespeare, the river has a much darker history as it once ran red with the blood of thousands of slain soldiers, when it was at the heart of one of the defining battles in the Wars of the Roses. Teaming up with one the UK’s few diving archeologists, Gary Bankhead, Rick and Beau discover an array of artefacts ranging from the time of The Wars of The Roses to the Victorian age in Warwick. Next they head down the river to Tewkesbury to find a WW2 helmet and Victorian crockery.
