1971

February 8, 1971
In Operation Lam Son 719, three South Vietnamese divisions drive into Laos to attack two major enemy bases. Unknowingly, they are walking into a North Vietnamese trap. Over the next month, more than 9,000 South Vietnamese troops are killed or wounded. More than two thirds of the South Vietnamese Army's armored vehicles are destroyed, along with hundreds of U.S. helicopters and planes.
Summer 1971
While herbicides containing Dioxin were banned for use by the U.S. Department of Agriculture in 1968, spraying of Agent Orange continues in Vietnam until 1971. Operation Ranchhand has sprayed 11 million gallons of Agent Orange -- containing 240 pounds of the lethal chemical Dioxin -- on South Vietnam. More than one seventh of the country's total area has been laid waste.
