“What,” said the monk, “have you almost done preaching? Help me, in the name of God, seeing you will not in the name of the other spirit, or, by the habit which I wear, you shall repent it, tempore et loco praelibatis.”
"Tempore et loco praelibatis" means "for the place and time." The monk somehow gets himself stuck in the tree and unknowingly draws attention to himself. His clumsiness brings the enemy to them. But the words of encouragement from the monk ultimately start a plan to end the war. This chapter of the monk brings a sense of silliness to the battle and bravery to motivate them to keep fighting regardless of how many men they have.
