The history of the 1st Battalion, 9th Marines is marked by relentless combat and significant sacrifices, earning them a grim but respected moniker. Known as “The Walking Dead,” this battalion faced some of the most intense battles of the Vietnam War, enduring heavy casualties but showcasing immense bravery and resilience.
The Hell of July 2, 1967
On a fateful morning in July 1967, two Marine companies, Alpha and Bravo, advanced along Highway 561, unaware they were marching into a deadly trap. This engagement would culminate in the most devastating day for Marines during the Vietnam War. The ambush was orchestrated near “The Market Place” by North Vietnamese forces who employed flamethrowers for the first time, flushing Marines into open terrain where they were targeted by artillery, mortars, and small arms fire. By day’s end, 84 Marines had fallen, 190 were injured, and nine were unaccounted for.
Origins of “The Walking Dead”
Arriving in Vietnam in June 1965, the 1st Battalion, 9th Marines quickly became embroiled in the conflict. Their initial deployment involved numerous missions, resulting in over 100 Marines killed within the first year. As the war intensified, the battalion found itself in areas like “Leatherneck Square,” notorious for its high casualty rates. The battalion’s nickname reportedly originated from North Vietnamese leaders, who allegedly vowed to annihilate the Marines as a gift to Ho Chi Minh, dubbing them “Di Bo Chet” or “The Walking Dead.” This nickname, intended to intimidate, was instead embraced by the Marines as a symbol of their tenacity.
The Bloodiest Confrontations
Operation Buffalo, which began on July 2, 1967, stands as a testament to the savage conditions faced by the battalion. North Vietnamese forces launched a vicious ambush against the Marines, resulting in catastrophic losses. Despite reinforcements, the operation claimed 159 Marine lives over its two-week duration, with 845 wounded.
Just months earlier, during Operation Prairie III, Sgt. Walter K. Singleton exhibited extraordinary bravery, posthumously earning the Medal of Honor for his actions in leading an assault under heavy fire, saving fellow Marines at the cost of his own life.
Enduring the Siege of Khe Sanh
In early 1968, the battalion was deployed to reinforce Khe Sanh Combat Base, coinciding with a notorious 77-day siege. Surviving relentless artillery bombardments, the Marines maintained their defensive positions, repelling numerous assaults and suffering significant casualties. The siege ended in April, with Marine losses totaling 205 killed and 1,662 wounded.
Operation Dewey Canyon and Final Deployments
In 1969, Operation Dewey Canyon marked the last major offensive for the Marines in Vietnam. During this operation, 1st Lt. Wesley Fox led his company through a deadly ambush, earning the Medal of Honor for his leadership and bravery. This campaign resulted in 130 Marine deaths and 932 wounded, highlighting the ongoing sacrifices of the battalion.
A Legacy of Valor
The 1st Battalion, 9th Marines, left an indelible mark on the Vietnam War, participating in 44 major operations and earning numerous commendations. Despite their heavy losses, the battalion’s legacy is one of resilience and courage, reflected in the stories of individuals like Sgt. Singleton and Lt. Fox. The battalion was eventually deactivated in 1994, but their history remains a powerful testament to their sacrifices and valor.
