Feb. 6-8: At the Honolulu Conference, attended by U.S. and South Vietnamese leaders, President Lyndon Johnson takes a strong stand on the need for pacification. He presses U.S. and South Vietnamese officials to expedite programs in such areas as health, education and building democracy to fight Communist influence in the south.

Feb. 14: While operating in the Gulf of Thailand off South Vietnam, PCF-4 is sunk by an underwater mine, killing four of her six crew. She is the first Swift Boat lost in action in Vietnam.

March 26: In order to curb Viet Cong attacks on merchant ships plying the Long Tau shipping channel leading to Saigon, U.S. Navy, U.S. Marine and South Vietnamese forces launch the first allied amphibious assault in the Rung Sat Special Zone, 35 miles south of Saigon. At the end of the 12-day effort, the allies had killed or captured 69 Viet Cong, destroyed Viet Cong bases and restricted enemy movements in this area.

April 1: U.S. Naval Forces Vietnam, responsible for all U.S. Navy forces in South Vietnam and some offshore units, is established under the command of Rear Adm. Norvell G. Ward.

April 12: Strategic Air Command B-52 bombers strike targets in North Vietnam for the first time. They hit a supply route in the Mu Gia Pass, north of the Demilitarized Zone. A B-52 bomber drops 1,000- and 750-pound bombs on a target 25 miles from Bien Hoa Air Base.

April 26: Flying a U.S. Air Force F-4 Phantom equipped with Sidewinder missiles, Maj. Paul Gilmore and 1st Lt. William Smith down the first MiG-21 over North Vietnam. The appearance of the MiG-21 in the skies of North Vietnam in 1966 signals an escalation of the air war. From 1966 onward, these planes operate sporadically, mainly in the air defense role. The MiG-21 was powered by an afterburning turbojet and could achieve speeds in excess of 1,300 mph.

July 1: A C-141 makes the first U.S. Air Force medevac flight from Vietnam directly to the United States, transporting 60 patients from Tan Son Nhut to Travis Air Force Base, Calif.

July 6: Fifty-two American prisoners of war are marched through the streets of Hanoi by their captors and are battered and bloodied by the many thousands of spectators. The propaganda event provokes widespread condemnation in the United States and produces shock waves at home and abroad that compel the Johnson administration to come to grips with the prisoner of war issue as a day-to-day problem.

July 7-Aug. 2: The 3d Marine Division Task Force Delta conducts Operation Hastings just south of the Demilitarized Zone dividing the two Vietnams. The Marine task force successfully repulses the 324th PAVN Division in its attempt to move into northern Quang Tri province. This marked the beginning of the North Vietnamese effort to move in strength directly through the DMZ. It would result in the move of the entire 3rd Marine Division northward to establish a forward headquarters at Dong Ha in northern Quang Tri province.

Aug. 11: U.S. Air Force B-57s and F-4s mistakenly attack the Coast Guard cutter Point Welcome, killing its commander, Lt. (junior grade) David C. Brostrom, the first Coast Guardsmen killed in Vietnam, and Engineman Second Class Jerry Phillips. The attacks wound all nine of the other crewmen plus a journalist and a South Vietnamese liaison officer.

Aug. 30: Taking over from Army pilots, naval aviators begin flying UH-1B “Huey” helicopters in support of riverine operations. The success of the helicopter missions results in the eventual establishment of Helicopter Attack (Light) Squadron 3. Called the Seawolves, it is one of the most highly decorated Navy squadrons in the Vietnam War.

Sept. 1: The first Purple Dragon study begins in September 1966 and lasts for six months. National Security Agency civilians and U.S. Navy personnel examine the problem of operational security during the air war in Vietnam. In particular, the study seeks to determine how the North Vietnamese get early warning of Rolling Thunder and Arc Light strikes. Purple Dragon studies became the foundation of the operational security concept adopted by the U.S. military.

Sept. 6: The U.S. Marine Corps asks women Marines to volunteer to serve in the Far East. By February 1969, more than 100 women are stationed in Japan and Vietnam.

Sept. 8: The 11th Armored Cavalry Regiment arrives in Vietnam. The only U.S. armored cavalry regiment to fight in the war, it would use its 51 tanks, 18 self-propelled howitzers, 48 helicopters and more than 300 armored personnel carriers to inflict heavy damage on the enemy in the open terrain of South Vietnam’s III Corps Tactical Zone.

Nov. 29: The Marines establish a one-battalion base area near the U.S. Special Forces Camp at Khe Sanh in northwestern Quang Tri province. This is the first establishment of a permanent Marine base at Khe Sanh.

Dec. 14: The Air Force loses its first plane to an air-to-air missile fired by a MiG-21 over North Vietnam.

Dec. 16: Wrapping up America’s massive ground combat deployment to Vietnam in 1966, the 9th Infantry Division takes up station south and east of Saigon, thereby completing the ring of U.S. divisions assigned to protect the heavily populated capital region.
