Psychological repercussions

These tunnels hugely impacted American morale as it was difficult to comprehend that the enemy could be hiding just feet away yet were undetectable and unreachable. Frank Gutierrez, for example, served with the US Army in Vietnam from 1967 to 1970 as a rifleman, field wireman, and an ordinance specialist at Chu Chi and Long Binh. When interviewed he stated: “We often wondered how things happened in the night and we never saw what was going on, guys getting their throat cut. Nobody ever knew where these guys were coming from… they pointed out in jungle school that there was a tunnel system… we had numerous tunnel rats, but we never knew exactly where or how extensive or where the entrance were. We just didn’t know. I didn’t know.”

One of the huge psychological issues for tunnel rats was the closeness of combat. Even if they could deal with the claustrophobic conditions, air and artillery support had not prepared them for the type of old-fashioned combat that relied on savage behaviour, individual strength, guts, and cunningness. The Viet Cong, with their lack of funding, was more skilled in this area given the necessity of their style of warfare. One Viet Cong technique was to slit a man’s throat or garrotte him as he came up through a connecting trap door; this often did not phase the men.

When it came to Americans, however, some found it difficult to kill when they were face-to-face with the enemy in such tight confines. Naturally, there were only first chances, never second, so some simply killed as they had to. On occasion, they ended up having severe nervous breakdowns and their colleagues dragged them out of tunnels crying and screaming. Sergeant Arnold Gutierrez of the 25th Division stated that after a while they became so tuned to what was happening “that when the other person would flick an eyelid up or down, you really knew he was there, in the corner, not even hiding anymore. Just sitting and waiting. [But] They were the ones you never killed. You just backed out and told them up above the tunnel was cold.”

How successful were they?

The United States conducted two major campaigns to search and destroy the tunnel system: Operation Crimp (1966) and Operation Cedar Falls (1967). Operation Crimp hoped to target a key Viet Cong headquarter location believed to be unground. Significant causalities ensued on both sides, but the combined Australian and American forces were unable to fully uncover the extensive tunnel network. Similarly, Operation Ceder Falls attempts to uncover and destroy the tunnel system. This attempt enjoyed more success than Crimp, but was short-lived as the tunnels were in working order again within weeks.

Overall, the Vietnamese were very quick to restore damage and continue as if nothing happened. This restoration was pivotal as it enabled some of the key successes enjoyed by the Viet Cong. Mai Chi Tho, brother of Le Duc Tho (a prominent Hanoi Politburo member) highlights how they used the tunnels to infiltrate Saigon. Tho claims the Viet Cong prepared both the necessary troops and assembled the supplies needed in these tunnels to conduct the Tet Offensive of 1968. This offensive is commonly seen by historians as a turning point for American involvement in Vietnam war.

In hindsight, listening to the Viet Cong talk about their experiences in these tunnels, it appears more training certainly would have benefitted the American cause. One Viet Cong soldier highlighted their lack of discreteness. Tunnel rat soldiers often used flashlights to guide the way and thus warned the enemy of their presence. In fact, volunteers boasted of their ability to change flashlights in the pitch black without realising the damaging consequences of this. Similarly, one American soldier highlighted how they liked to ‘soften things up’ by throwing in one or more hand grenades before sending in tunnel rats. However, as the Viet Cong soldier highlighted, by throwing grenades into the void ahead, or shooting pistols, the noise was deafening and alerted them to their presence.

Needless to say, sadly many of those Americans who did enter the tunnels ended up dying. The exact figure, however, remains unknown as there were no extensive records kept on this exact type of engagement with the enemy. According to archives held by the US government, there were 58,220 US military deaths overall as a result of the Vietnam War. The War also claimed the lives of approximately 200,000 allied soldiers in Vietnam, nearly one million North Vietnamese/ Communist allied deaths, and an incomprehensible number of civilians.
