Capítulo 558: 558: The Grand Glade War VIII

Close to 800 Raens marched through the tunnel, all of them coming to line up in front of the barrier in front of the tunnel that led straight to the central Glade. Word had come down that the rest of the fighters above had pushed the central glade back , until they had retreated back into their territory proper.

So basically this was siege, they had taken the fight from off the battlefield, and now they had laid siege on the central Glade. There were putting some soldiers in front of the sealed off tunnel, as a deterrence in case the central Glade decides that it wasted to attack again. As for the other tunnels, Cole had sent runners to check them out and see if it lead elsewhere or if there were any other branching tunnels that they needed to know about.
