Underground

As Matthias is lost deep in Asmodeus's caverns, Cluny digs his way under Redwall, taking advantage of the exhausted Redwallers and the absence of Matthias. Using the sword to escape the caverns and after a terrifying river adventure, Matthias returns with the shrews to defend Redwall - but not before he is almost trapped by Cluny and only just saved by Cornflower. Cluny flees at the sight of Martin The Warrior's "ghost" while Matthias at last gets to wear his hero's armor.
