Spear Trap
The three of them waited for the forces from the rear city to come a bit closer.
Sam knew they would be coming earlier than the forces from the front city, because he released the captives just for this reason. He knew that they would go and ramble their mouths to the rear city to save their lives.
After all they wouldn't be able to just disappear into thin air, not before crossing the rear city and since all the flow of the people for the rear city are stopped from their current location, it is hard for them to blend into some random group and disguise themselves casually and escape.
Sam counted on it and it actually happened. They sent a lot of forces too.
But they are moving too slow. They are too cautious, they move like every step they are taking is a trap.
Sam looked at them for more than an hour and they barely reached the place of their first trap. The first trap in the rear path. It belongs to Kumar.
He set it up.
