Note: There were many more important – possibly, even more significant – events during this year. This brief chronology will provide little more than a general the framework: a context into which other noteworthy events may be placed.

February 21, 1967 - Dr. Bernard Fall, noted historian of the French combat experience in Indochina, died in an explosion of an enemy mine. Dr. Fall was accompanying the 1st Battalion, 9th Marines in Operation Chinook.

Significance: Dr. Fall was a recognized expert on Vietnam and ironically died in an area near the so called "Street Without Joy," which he had so carefully portrayed in his writing. He was one of the South Vietnamese regime.

February 27, 1967 - NVA rocket troops launched 140 mm rockets against the Da Nang Air Base. More than 50 rockets hit the base in less than a minute. The rockets had a range of 9,000 meters.

Significance: This was the first know use of large tactical rockets in South Vietnam. The use of these weapons forced III MAF to extend its protective patrolling at Da Nang out to 9,000 meters, which added to the drain on Marine infantry manpower.

March 18, 1967 - The first woman Marine to serve in Vietnam, M/Sgt Barbara J. Dulinsky, arrived in Saigon, for assignment to the MACV combat operations center.

March 26, 1967 - COMUSMACV ordered III MAF to prepare a plan for locating, constructing, and occupying a strongpoint obstacle system south of the DMZ to prevent the North Vietnamese from infiltrating through that zone into South Vietnam.
Significance: III MAF eventually began building this strongpoint system later in the year while under fire by North Vietnamese artillery. This anti-infiltration effort, also known as Dye Marker and Project Nine was labeled by the Media as "McNamara's Wall," after the name of the U.S. Secretary of Defense Robert S. McNamara.

April 20, 1967 - U.S. Army Task Force Oregon under Major General William B. Rosson (USA) established its headquarters at Chu Lai and came under the operational control of III MAF to reinforce the Marines in I Corps. Eventually on September 20, Task Force Oregon became the U.S. Army Americal Division under Major General Samuel W. Koster (USA).
Significance: III MAF became truly a U.S. joint command with a sizable Army contingent under its operational control

April 24 - May 11, 1967 - The "First Battle of Khe Sanh" or "Hill Fights" took place. In extremely bitter fighting with North Vietnamese troops, units of the 3rd Marine Division cleared Hills 8881S, 881N, and 861 overlooking the Khe Sanh Combat base.
Significance: Khe Sanh began to take on more importance as a Marine outpost. The American command insisted that it be held and the North Vietnamese continued to probe and try to isolate the garrison.

May 31, 1967 - LtGen Robert E. Cushman, Jr. succeeded LtGen Lewis W. Walt as Commanding General III MAF.

Significance: General Walt who had become identified with the Marine Corps pacification campaign including the Combined Action Program was relieved after two emphasize pacification as a central component of the Marine effort in South Vietnam especially in the heavily populated area around Da Nang.

July 2-14, 1967 - The 9th Marines conducted Operation Buffalo to counter a North Vietnamese offensive near the Marine base at Con Thien just south of the DMZ. In very intensive fighting with heavy casualties on both sides, the Marines repulsed the North Vietnamese.
Significance: The North Vietnamese in the eastern DMZ begin to escalate the war in the north and would continue to mount attacks against Con Thien.

September 19-27, 1967 - In a massive attack by fire on Con Thien, the North Vietnamese fired more than 3,000 heavy artillery, mortar, and rocket rounds against the Marine battalion at Con Thien. In response, U.S. artillery returned 12,577 rounds, Navy gun ships fired 6,148 rounds, and U.S. fighter/attack aircraft flew 5,200 missions against the enemy firing positions.

Significance: This was one of the heaviest North Vietnamese artillery bombardments against American troops during the war and was the first phase of the Communist 1967-1968 Winter Spring Campaign that would culminate in the 1968 Tet offensive.
