Vo Khac Diep, Ho Viet Lai, and I were traveling as guerrilla fighters, and we had to set off first. The rainy season had begun, the grass was lush green, and the tendrils of water spinach swayed among the mangrove trees and under the banyan trees along the canal bank. The three of us left Coi Nhi, Khanh Binh Tay commune, with backpacks of clothes, sacks of rice, a cooking container, some salt, pepper, and MSG, and began a long trek that we estimated would take several months. With youthful enthusiasm, we eagerly set off to discover new things we had never experienced before.

For two days, we stayed on this side of the Cai San road, waiting for the messenger. Every morning and evening, we went down to the canal to practice swimming, preparing ourselves to face and overcome danger, because many times before, our cadres and soldiers passing through here had been ambushed and surrounded by enemy checkpoints, and some comrades had even been killed. The people living along this road were all Catholics who had been brought here by Ngo Dinh Diem in 1954, with the slogan "God has come to the South," and were indoctrinated with blind anti-communist ideology; houses were about 5-7 meters apart, with barbed wire fences about 1 meter high in front of each house; every kilometer there was an enemy outpost. In such dangerous circumstances, we safely crossed the road: even though we were carrying bags of supplies weighing more than 10 kg on our backs, we easily jumped over the fence, then waded across the roadside ditch. Fortunately, it was a clear summer night with many stars shining brightly, so we didn't have to worry about getting separated.

Having passed the safe road, the tension eased, but we still had to cross a field about 20 km long to reach the Tram Duong area before dawn. This was a sparsely forested mangrove area; places with dense canopies, which helped conceal us from the enemy's "old ladies," OV-10 planes, and "bucket-handled" helicopters, as well as having tree trunks strong enough to support hammocks, had become "reservoirs" for troops arriving and departing – a crucial point on the strategic transport route across the Cambodian border, connecting to the legendary Truong Son Trail.
