Ho Chi Minh trail symbolises how the Vietnamese used their limited resources to great advantage. About 20,000 North Vietnamese troops came to South Vietnam each month on this trail. The trail had support bases and hospitals along the way. In some parts, the supplies were transported in trucks, but mostly they were carried by porters, who were mainly women. These porters carried about 25 kilos on their backs or about 70 kilos on their bicycles. Most of the trails were outside Vietnam in neighbouring Laos and Cambodia with branch lines extending into South Vietnam.
The US regularly bombed this trail trying to disrupt supplies but efforts to destroy this important supply line by intensive bombing failed because they were rebuilt very quickly.
