Part of the reason for this was the size of the convoy. It was one thing for a nimble, flexible, and fast Martial Apprentices to travel the Serevian Plateau. It was entirely another thing for large convoys such as the Kandrian Empire's Serevian Dungeon team to travel the Serevian Plateau.
The biggest difference was the size which made them extremely loud and conspicuous. On top of their conspicuity, their inability to easily and swiftly retreat and disengage from any conflict that may arise made their position that much more vulnerable. Martial Apprentices often simply retreated or escaped in the face of grave danger.
But in this case, they couldn't.
