Bến Tre's significance to the Vietcong went back nearly a decade before Tet. In January 1960, Nguyễn Thị Định — one of the very few high-ranking women in the VC — led the first large-scale armed rebellion against the South Vietnamese government here, capturing ten government buildings and assassinating 43 individuals. Though ARVN forces retook the city ten days later, the rebellion became a foundational story for the southern insurgency. The rural terrain surrounding Bến Tre, an island province with no bridge links to its four neighboring provinces, provided ideal conditions for guerrilla operations. By the mid-1960s, the area served as a critical VC base. As Brigadier General William Robertson Desobry noted in a 1968 debriefing: "The population is fractured, is dissident and in general has little if any history of loyalty to Saigon."

The attack began on January 31 as part of the coordinated Tet Offensive, striking simultaneously across South Vietnam during what was supposed to be a ceasefire for the Lunar New Year. Within sixteen hours, the Vietcong controlled virtually the entire city and a string of fishing villages along the Bến Tre River's south bank. Allied forces clung to a four-square-block perimeter surrounding the MACV compound, the Provincial headquarters, and the main police station. Two ARVN battalions from the 10th Regiment tried to fight through, but their regimental commander had been killed leading the assault. With the U.S. Mobile Riverine Force focused on saving nearby Mỹ Tho, Bến Tre's defenders were largely on their own, relying on airpower and naval gunfire to keep from being overrun entirely.

PBRs 7-20 and 7-21 were patrolling the Hàm Luông River when they first heard the shooting. The crews initially mistook it for Vietnamese soldiers celebrating Tết, until they spotted the telltale green tracer rounds of the Vietcong arcing above the city. Moving down the Bến Tre River to investigate, they found six South Vietnamese Navy landing craft firing at targets along the south bank. When the MACV compound radioed for gunfire support, the patrol boats headed upriver. Low tide and high riverbanks worked in their favor — VC gunners struggled to depress their fire enough to hit the boats, and most rounds passed harmlessly overhead. The PBRs' .50-caliber machine guns answered with armor-piercing incendiary rounds, and within a minute the enemy guns fell silent. It was a small engagement in a battle that would last five more days, but for the sailors on those boats, the distinction between fireworks and war had closed in seconds.

The battle ground on until February 5, when U.S. and South Vietnamese forces finally ejected the Vietcong, who suffered 328 killed. But the cost to Bến Tre itself was devastating. The heavy reliance on airpower and naval bombardment to dislodge entrenched fighters from a populated city left block after block in rubble. It was in this aftermath that Peter Arnett filed his report, quoting the unnamed major's remark about destroying the town to save it. The quote — often paraphrased as "We had to destroy the village in order to save it" — spread rapidly through American media. Its veracity has been debated for decades, but as military historian William H. Hammond later wrote, the phrase "passed into the lore of the war to become one of the most serviceable icons of the anti-war movement." Whether the major said exactly those words mattered less than the fact that Bến Tre made them believable.

Seen from the air today, Bến Tre is a green tapestry of coconut palms and fruit orchards threaded with silver waterways. The city sits on an island in the Mekong, and from altitude the surrounding delta reveals its true character: not solid land but a lattice of rivers, canals, and flooded paddies that makes conventional military movement almost impossible. It is easy to understand, looking down, both why guerrilla fighters thrived here and why conventional forces turned to overwhelming firepower when the ground itself seemed to resist them. The scars of 1968 have long since healed over with tropical growth, but the geography that shaped the battle remains unchanged — water everywhere, and solid ground a matter of negotiation.
