US : artillery and bomber aircraft in 1960 in Ho Minh Cu Chi Chi
The tunnel network of Cu Chi District, now part of Greater Ho Chi Minh City, became legendary during the 1960s for its role in facilitating Viet Cong control of a large rural area only 30 km north-west of Saigon. At its height, the tunnel system stretched from the South - Vietnamese capital to the Cambodian border.
In the district of Cu Chi alone, there were over 200 km of tunnels. After ground opera- tions against the tunnels claimed large en numbers of casualties and proved ineffective, the Americans turned their artillery and bombers on the area, turning it into a moonscape.
Parts of this remarkable tunnel network have been reconstructed in the interests of promoting Vietnamese patriotism and mass foreign tourism.
