Red oversaw the work as soon as the Chief agreed with his plan. At this point, the Chief wanted to try every idea Red threw at him.
The idea was simple: digging a hole for a trap in the area near the wall. They had enough manpower, more than enough. In fact, the hobgoblin worked much faster than the goblins.
He wanted the hole to be deep, as deep as twice his height, with the length matching the wall. That was not just a hole to trap the kobold. They also prepared the wooden spike. Ideally, metal spikes would work better. He thought of using the spear, but they didn't have enough spears to fill the trap. So yeah, they used the wooden spikes instead.
Seventy hobgoblins were digging the trap, and the remaining hobgoblins were making the spikes. The hobgoblins worked so fast. That may be because of the Chief's direct order. Not just that, they also listened to him well. None of them were getting cocky or hostile toward him.
