Redwall (1999)

Conspiring with Matthias, Constance builds a huge crossbow and shoots Cluny - but Cluny uses a substitute and escapes her arrow. Unknown to Redwall, he plans an attack with a huge movable siege tower. The abbey is saved when courageous Cornflower single handedly burns it down. Only then does the abbey realize Cluny is still alive and only Cornflower stood between them and disaster. Matthias and Cornflower become even closer warrior friends.
