The tunnels were first built and used by the Viet Minh and gave a peasant army an efficient method of transportation against a high-tech enemy. The Cu Chi area was know as The Iron Triangle and US and Australian troops tried to pacify it with napalm defoliation, excavation and burning. The VC managed to survive in the tunnels because they were up to three or four levels deep. The VC mainly fought at night when the enemy were in camp. The Americans used German Shepherd sniffer dogs to track down the VC but they were outsmarted by chilli pepper. The VC also washed in American soap and used clothing of killed soldiers to trick the dogs.
