January 27, 1965 - Johnson aides, National Security Advisor McGeorge Bundy and Defense Secretary Robert McNamara, send a memo to the President stating that America's limited military involvement in Vietnam is not succeeding, and that the U.S. has reached a 'fork in the road' in Vietnam and must either soon escalate or withdraw.

January 1965 - Operation Game Warden begins U.S. Navy river patrols on South Vietnam's 3000 nautical miles of inland waterways.

February 7-8 - "I've had enough of this," President Johnson tells his National Security advisors. He then approves Operation Flaming Dart, the bombing of a North Vietnamese army camp near Dong Hoi by U.S. Navy jets from the carrier Ranger.

Johnson makes no speeches or public statements concerning his decision. Opinion polls taken in the U.S. shortly after the bombing indicate a 70 percent approval rating for the President and an 80 percent approval of U.S. military involvement in Vietnam. Johnson now agrees to a long-standing recommendation from his advisors for a sustained bombing campaign against North Vietnam.

In Hanoi, Soviet Prime Minister Kosygin is pressured by the North Vietnamese to provide unlimited military aid to counter the American "aggression." Kosygin gives in to their demands. As a result, sophisticated Soviet surface-to-air missiles (SAMs) begin arriving in Hanoi within weeks.

February 18, 1965 - Another military coup in Saigon results in General Khanh finally ousted from power and a new military/civilian government installed, led by Dr. Phan Huy Quat.

February 22, 1965 - General Westmoreland requests two battalions of U.S. Marines to protect the American air base at Da Nang from 6000 Viet Cong massed in the vicinity. The President approves his request, despite the "grave reservations" of Ambassador Taylor in Vietnam who warns that America may be about to repeat the same mistakes made by the French in sending ever-increasing numbers of soldiers into the Asian forests and jungles of a "hostile foreign country" where friend and foe are indistinguishable.

March 2, 1965 - Operation Rolling Thunder begins as over 100 American fighter-bombers attack targets in North Vietnam. Scheduled to last eight weeks, Rolling Thunder will instead go on for three years.

The first U.S. air strikes also occur against the Ho Chi Minh trail. Throughout the war, the trail is heavily bombed by American jets with little actual success in halting the tremendous flow of soldiers and supplies from the North. 500 American jets will be lost attacking the trail. After each attack, bomb damage along the trail is repaired by female construction crews.

During the entire war, the U.S. will fly 3 million sorties and drop nearly 8 million tons of bombs, four times the tonnage dropped during all of World War II, in the largest display of firepower in the history of warfare.

The majority of bombs are dropped in South Vietnam against Viet Cong and North Vietnamese Army positions, resulting in 3 million civilian refugees due to the destruction of numerous villages. In North Vietnam, military targets include fuel depots and factories. The North Vietnamese react to the air strikes by decentralizing their factories and supply bases, thus minimizing their vulnerability to bomb damage.

March 8, 1965 - The first U.S. combat troops arrive in Vietnam as 3500 Marines land at China Beach to defend the American air base at Da Nang. They join 23,000 American military advisors already in Vietnam.

March 29, 1965 - Viet Cong terrorists bomb the U.S. embassy in Saigon.

April 1, 1965 - At the White House, President Johnson authorizes sending two more Marine battalions and up to 20,000 logistical personnel to Vietnam. The President also authorizes American combat troops to conduct patrols to root out Viet Cong in the countryside. His decision to allow offensive operations is kept secret from the American press and public for two months.

April 7, 1965 - President Johnson delivers his "Peace Without Conquest" Speech at Johns Hopkins University offering Hanoi "unconditional discussions" to stop the war in return for massive economic assistance in modernizing Vietnam. "Old Ho can't turn that down," Johnson privately tells his aides. But Johnson's peace overture is quickly rejected.

April 15, 1965 - A thousand tons of bombs are dropped on Viet Cong positions by U.S. and South Vietnamese fighter-bombers.

May 13, 1965 - Viet Cong attack the U.S. special forces camp in Phuoc Long. During the fighting, 2nd Lt. Charles Williams, earns the Congressional Medal of Honor by knocking out a Viet Cong machine-gun then guiding rescue helicopters, while wounded four times.

We cannot be defeated by force of arms. We will stand in Vietnam."

"...I do not find it easy to send the flower of our youth, our finest young men, into battle. I have spoken to you today of the divisions and the forces and the battalions and the units, but I know them all, every one. I have seen them in a thousand streets, of a hundred towns, in every state in this union�working and laughing and building, and filled with hope and life. I think I know, too, how their mothers weep and how their families sorrow."

November 14 -16 - The Battle of Ia Drang Valley marks the first major battle between U.S. troops and North Vietnamese Army regulars (NVA) inside South Vietnam. American Army troops of the 1st Cavalry Division (Airmobile) respond to the NVA threat by using helicopters to fly directly into the battle zone. Upon landing, the troops quickly disembark then engage in fierce fire fights, supported by heavy artillery and B-52 air strikes, marking the first use of B-52s to assist combat troops. The two-day battle ends with NVA retreating into the jungle. 79 Americans are killed and 121 wounded. NVA losses are estimated at 2000.

November 17, 1965 - The American success at Ia Drang is marred by a deadly ambush against 400 soldiers of the U.S. 7th Cavalry sent on foot to occupy nearby Landing Zone 'Albany.'

1966

January 12, 1966 - During his State of the Union address before Congress, President Johnson comments that the war in Vietnam is unlike America's previous wars, "Yet, finally, war is always the same. It is young men dying in the fullness of their promise. It is trying to kill a man that you do not even know well enough to hate...therefore, to know war is to know that there is still madness in this world."

January 28 - March 6 - Operation Masher marks the beginning of large-scale U.S. search-and-destroy operations against Viet Cong and NVA troop encampments. However, President Johnson orders the name changed to the less aggressive sounding 'White Wing' over concern for U.S. public opinion. During the 42 day operation in South Vietnam's Bon Son Plain near the coast, troopers of the U.S. 1st Cavalry Division (Airmobile) once again fly by helicopters directly into battle zones and engage in heavy fighting. 228 Americans are killed and 788 wounded. NVA losses are put at 1342.

The term 'search-and-destroy' is used by the media to describe everything from large scale Airmobile troop movements to small patrols rooting out Viet Cong in tiny hamlets. The term eventually becomes associated with negative images of Americans burning villages.

January 31, 1966 - Senator Robert F. Kennedy criticizes President Johnson's decision to resume the bombing, stating that the U.S. may be headed "on a road from which there is no turning back, a road that leads to catastrophe for all mankind." His comments infuriate the President.

February 1966 - The Senate Foreign Relations Committee, chaired by Sen. J. William Fulbright, holds televised hearings examining America's policy in Vietnam. Appearing before the committee, Defense Secretary McNamara states that U.S. objectives in Vietnam are "not to destroy or overthrow the Communist government of North Vietnam. They are limited to the destruction of the insurrection and aggression directed by North Vietnamese against the political institutions of South Vietnam."

February 3, 1966 - Influential newspaper columnist Walter Lippmann lambastes President Johnson's strategy in Vietnam, stating, "Gestures, propaganda, public relations and bombing and more bombing will not work." Lippmann predicts Vietnam will divide America as combat causalities mount.

Over half of the American causalities are caused by snipers and small-arms fire during Viet Cong ambushes, along with handmade booby traps and mines planted everywhere in the countryside by Viet Cong. American Allies fighting in Vietnam include 45,000 soldiers from South Korea and 7000 Australians. An estimated 89,000 soldiers from North Vietnam infiltrated the South via the Ho Chi Minh trail in 1966.

1967

January 2, 1967 - Operation Bolo occurs as 28 U.S. Air Force F-4 Phantom jets lure North Vietnamese MiG-21 interceptors into a dogfight over Hanoi and shoot down seven of them. This leaves only nine MiG-21s operational for the North Vietnamese. American pilots, however, are prohibited by Washington from attacking MiG air bases in North Vietnam.

January 8 - 26 - Operation Cedar Falls occurs. It is the largest combined offensive to date and involves 16,000 American and 14,000 South Vietnamese soldiers clearing out Viet Cong from the 'Iron Triangle' area 25 miles northwest of Saigon. The Viet Cong choose not to fight and instead melt away into the jungle. Americans then uncover an extensive network of tunnels and for the first time use 'tunnel rats,' the nickname given to specially trained volunteers who explore the maze of tunnels. After the American and South Vietnamese troops leave the area, Viet Cong return and rebuild their sanctuary. This pattern is repeated throughout the war as Americans utilize 'in-and-out' tactics in which troops arrive by helicopters, secure an area, then depart by helicopters.

July 7, 1967 - North Vietnam's Politburo makes the decision to launch a widespread offensive against South Vietnam. Conceived in three phases, the first phase involves attacks against remote border areas in an effort to lure American troops away from South Vietnam's cities. The second phase (Tet Offensive) will be an attack against the cities themselves by Viet Cong forces aided by NVA troops, in the hope of igniting a "general uprising" to overthrow the government of South Vietnam.

Behind closed doors, he had begun regularly expressing doubts over Johnson's war strategy, angering the President. McNamara joins a growing list of Johnson's top aides who resigned over the war including Bill Moyers, McGeorge Bundy and George Ball.

November 30, 1967 - Anti-war Democrat Eugene McCarthy announces he will be a candidate for President opposing Lyndon Johnson, stating, "...we are involved in a very deep crisis of leadership, a crisis of direction and a crisis of national purpose...the entire history of this war in Vietnam, no matter what we call it, has been one of continued error and misjudgement."

December 4, 1967 - Four days of anti-war protests begin in New York. Among the 585 protestors arrested is renowned 'baby doctor' Dr. Benjamin Spock.

December 6, 1967 - The U.S. reports Viet Cong murdered 252 civilians in the hamlet of Dak Son.

December 23, 1967 - Upon arrival at Cam Ranh Bay in Vietnam, President Johnson declares "...all the challenges have been met. The enemy is not beaten, but he knows that he has met his master in the field." This is the President's second and final trip to Vietnam during his presidency.

By year's end, U.S. troop levels reach 463,000 with 16,000 combat deaths to date. By this time, over a million American soldiers have rotated through Vietnam, with length of service for draftees being one year, and most Americans serving in support units. An estimated 90,000 soldiers from North Vietnam infiltrated into the South via the Ho Chi Minh trail in 1967. Overall Viet Cong/NVA troop strength throughout South Vietnam is now estimated up to 300,000 men.

1968

January 5, 1968 - Operation Niagara I to map NVA positions around Khe Sanh begins.

January 21, 1968 - 20,000 NVA troops under the command of Gen. Giap attack the American air base at Khe Sanh. A 77 day siege begins as 5000 U.S. Marines in the isolated outpost are encircled. The siege attracts enormous media attention back in America, with many comparisons made to the 1954 Battle of Dien Bien Phu in which the French were surrounded then defeated.

"I don't want any damn Dinbinfoo," an anxious President Johnson tells Joint Chiefs Chairman Gen. Earle Wheeler. As Johnson personally sends off Marine reinforcements, he states "...the eyes of the nation and the eyes of the entire world, the eyes of all of history itself, are on that little brave band of defenders who hold the pass at Khe Sanh..." Johnson issues presidential orders to the Marines to hold the base and demands a guarantee "signed in blood" from the Joint Chiefs of Staff that they will succeed.

Operation Niagara II then begins a massive aerial supply effort to the besieged Marines along with heavy B-52 bombardment of NVA troop positions. At the peak of the battle, NVA soldiers are hit round-the-clock every 90 minutes by groups of three B-52s which drop over 110,000 tons of bombs during the siege, the heaviest bombardment of a small area in the history of warfare.

January 31, 1968 - The turning point of the war occurs as 84,000 Viet Cong guerrillas aided by NVA troops launch the Tet Offensive attacking a hundred cities and towns throughout South Vietnam.

The surprise offensive is closely observed by American TV news crews in Vietnam which film the U.S. embassy in Saigon being attacked by 17 Viet Cong commandos, along with bloody scenes from battle areas showing American soldiers under fire, dead and wounded. The graphic color film footage is then quickly relayed back to the states for broadcast on nightly news programs. Americans at home thus have a front row seat in their living rooms to the Viet Cong/NVA assaults against their fathers, sons and brothers, ten thousand miles away. "The whole thing stinks, really," says a Marine under fire at Hue after more than 100 Marines are killed.

January 31 - March 7 - In the Battle for Saigon during Tet, 35 NVA and Viet Cong battalions are defeated by 50 battalions of American and Allied troops that had been positioned to protect the city on a hunch by Lt. Gen. Fred C. Weyand, a veteran of World War II in the Pacific. Nicknamed the "savior of Saigon," Weyand had sensed the coming attack, prepared his troops, and on February 1 launched a decisive counter-attack against the Viet Cong at Tan Son Nhut airport thus protecting nearby MACV and South Vietnamese military headquarters from possible capture.

January 31 - March 2 - In the Battle for Hue during Tet, 12,000 NVA and Viet Cong troops storm the lightly defended historical city, then begin systematic executions of over 3000 "enemies of the people" including South Vietnamese government officials, captured South Vietnamese officers, and Catholic priests. South Vietnamese troops and three U.S. Marine battalions counter-attack and engage in the heaviest fighting of the entire Tet Offensive. They retake the old imperial city, house by house, street by street, aided by American air and artillery strikes. On February 24, U.S. Marines occupy the Imperial Palace in the heart of the citadel and the battle soon ends with a North Vietnamese defeat. American losses are 142 Marines killed and 857 wounded, 74 U.S. Army killed and 507 wounded. South Vietnamese suffer 384 killed and 1830 wounded. NVA killed are put at over 5000.

February 1, 1968 - In Saigon during Tet, a suspected Viet Cong guerrilla is shot in the head by South Vietnam's police chief Gen. Nguyen Ngoc Loan, in full view of an NBC news cameraman and an Associated Press still photographer. The haunting AP photo taken by Eddie Adams appears on the front page of most American newspapers the next morning. Americans also observe the filmed execution on NBC TV.

Another controversy during Tet, and one of the most controversial statements of the entire war, is made by an American officer who states, 'We had to destroy it, in order to save it,' referring to a small city near Saigon leveled by American bombs. His statement is later used by many as a metaphor for the American experience in Vietnam.

February 2, 1968 - President Johnson labels the Tet Offensive "a complete failure."

For the North Vietnamese, the Tet Offensive is both a military and political failure in Vietnam. The "general uprising" they had hoped to ignite among South Vietnamese peasants against the Saigon government never materialized. Viet Cong had also come out of hiding to do most of the actual fighting, suffered devastating losses, and never regained their former strength. As a result, most of the fighting will be taken over by North Vietnamese regulars fighting a conventional war. Tet's only success, and an unexpected one, was in eroding grassroots support among Americans and in Congress for continuing the war indefinitely.

February 8, 1968 - 21 U.S. Marines are killed by NVA at Khe Sanh.

February 27, 1968 - Influential CBS TV news anchorman Walter Cronkite, who just returned from Saigon, tells Americans during his CBS Evening News broadcast that he is certain "the bloody experience of Vietnam is to end in a stalemate."

February 28, 1968 - Joint Chiefs Chairman Gen. Wheeler, at the behest of Gen. Westmoreland, asks President Johnson for an additional 206,000 soldiers and mobilization of reserve units in the U.S.

March 1, 1968 - Clark Clifford, renowned Washington lawyer and an old friend of the President, becomes the new U.S. Secretary of Defense. For the next few days, Clifford conducts an intensive study of the entire situation in Vietnam, discovers there is no concept or overall plan anywhere in Washington for achieving victory in Vietnam, then reports to President Johnson that the United States should not escalate the war. "The time has come to decide where we go from here," he tells Johnson.

March 2, 1968 - 48 U.S. Army soldiers are killed during an ambush at Tan Son Nhut airport in Saigon.

March 10, 1968 - The New York Times breaks the news of Westmoreland's 206,000 troop request. The Times story is denied by the White House. Secretary of State Dean Rusk is then called before the Senate Foreign Relations Committee and grilled for two days on live TV about the troop request and the overall effectiveness of Johnson's war strategy.

March 11, 1968 - Operation Quyet Thang begins a 28 day offensive by 33 U.S. and South Vietnamese battalions in the Saigon region.

March 12, 1968 - By a very slim margin of just 300 votes, President Johnson defeats anti-war Democrat Eugene McCarthy in the New Hampshire Democratic primary election. This indicates that political support for Johnson is seriously eroding.

Public opinion polls taken after the Tet Offensive revealed Johnson's overall approval rating has slipped to 36 percent, while approval of his Vietnam war policy slipped to 26 percent.

March 14, 1968 - Senator Robert F. Kennedy offers President Johnson a confidential political proposition. Kennedy will agree to stay out of the presidential race if Johnson will renounce his earlier Vietnam strategy and appoint a committee, including Kennedy, to chart a new course in Vietnam. Johnson spurns the offer.

March 16, 1968 - Robert F. Kennedy announces his candidacy for the presidency. Polls indicate Kennedy is now more popular than the President.

During his campaign, Kennedy addresses the issue of his participation in forming President John F. Kennedy's Vietnam policy by stating, "past error is no excuse for its own perpetuation."

March 16, 1968 - Over 300 Vietnamese civilians are slaughtered in My Lai hamlet by members of Charlie Company, 1st Battalion, 20th Infantry U.S. Army, while participating in an airborne assault against suspected Viet Cong encampments in Quang Ngai Province. Upon entering My Lai and finding no Viet Cong, the Americans begin killing every civilian in sight, interrupted only by helicopter pilot Hugh Thompson who lands and begins evacuating civilians after realizing what is happening.

March 28, 1968 - The initial report by participants at My Lai states that 69 Viet Cong soldiers were killed and makes no mention of civilian causalities.

The My Lai massacre is successfully concealed for a year, until a series of letters from Vietnam veteran Ronald Ridenhour spark an official Army investigation that results in Charlie Company Commander, Capt. Ernest L. Medina, First Platoon Leader, Lt. William Calley, and 14 others being brought to trial by the Army. A news photos of the carnage, showing a mass of dead children, women and old men, remains one of the most enduring images of America's involvement in Vietnam.

March 23, 1968 - During a secret meeting in the Philippines, Gen Wheeler informs Gen. Westmoreland that President Johnson will approve only 13,500 additional soldiers out of the original 206,000 requested. Gen. Wheeler also instructs Westmoreland to urge the South Vietnamese to expand their own war effort.

March 25, 1968 - Clark Clifford convenes the "Wise Men," a dozen distinguished elder statesmen and soldiers, including former Secretary of State Dean Acheson and World War II General Omar Bradley at the State Department for dinner. They are given a blunt assessment of the situation in Vietnam, including the widespread corruption of the Saigon government and the unlikely prospect for military victory "under the present circumstances."

March 26, 1968 - The "Wise Men" gather at the White House for lunch with the President. They now advocate U.S. withdrawal from Vietnam, with only four of those present dissenting from that opinion.

March 31, 1968 - President Johnson stuns the world by announcing his surprise decision not to seek re-election. He also announces a partial bombing halt and urges Hanoi to begin peace talks. "We are prepared to move immediately toward peace through negotiations." As a result, peace talks soon begin. The bombing halt only affects targets north of the 20th parallel, including Hanoi.

April 1, 1968 - The U.S. 1st Cavalry Division (Airmobile) begins Operation Pegasus to reopen Route 9, the relief route to the besieged Marines at Khe Sanh.

April 4, 1968 - Civil rights leader Rev. Dr. Martin Luther King is assassinated in Memphis. Racial unrest then erupts in over 100 American cities.

April 8, 1968 - The siege of Khe Sanh ends with the withdrawal of NVA troops from the area as a result of intensive American bombing and the reopening of Route 9. NVA losses during the siege are estimated up to 15,000. U.S. Marines suffered 199 killed and 830 wounded. 1st Cavalry suffered 92 killed and 629 wounded reopening Route 9. The U.S. command then secretly shuts down the Khe Sanh air base and withdraws the Marines. Commenting on the heroism of U.S. troops that defended Khe Sanh, President Johnson states "...they vividly demonstrated to the enemy the utter futility of his attempts to win a military victory in the South." A North Vietnamese official labels the closing of Khe Sanh air base as America's "gravest defeat" so far.

April 11, 1968 - Defense Secretary Clifford announces Gen. Westmoreland's request for 206,000 additional soldiers will not be granted.

April 23, 1968 - Anti-war activists at Columbia University seize five buildings.

April 27, 1968 - In New York, 200,000 students refuse to attend classes as a protest.

April 30 - May 3 - The Battle of Dai Do occurs along the Demilitarized Zone as NVA troops seek to open an invasion corridor into South Vietnam. They are halted by a battalion of U.S. Marines nicknamed "the Magnificent Bastards" under the command of Lt. Col. William Weise. Aided by heavy artillery and air strikes, NVA suffer 1568 killed. 81 Marines are killed and 297 wounded. 29 U.S. Army are killed supporting the Marines and 130 wounded.

For the time being, this defeat ends North Vietnam's hope of successfully invading the South. They will wait four years, until 1972, before trying again, after most of the Americans have gone. It will actually take seven years, until 1975, for them to succeed.

May 5, 1968 - Viet Cong launch "Mini Tet," a series of rocket and mortar attacks against Saigon and 119 cities and military installations throughout South Vietnam. The U.S. responds with air strikes using Napalm and high explosives.

May 10, 1968 - An NVA battalion attacks the Special Forces camp at Kham Duc along the border of Laos. The isolated camp had been established in 1963 to monitor North Vietnamese infiltration. Now encircled by NVA, the decision is made to evacuate via C-130 transport planes. At the conclusion of the successful airlift, it is discovered that three U.S. Air Force controllers have accidentally been left behind. Although the camp is now over-run by NVA and two C-130s have already been shot down, Lt. Col. Joe M. Jackson pilots a C-123 Provider, lands on the air strip under intense fire, gathers all three controllers, then takes off. For this, Jackson is awarded the Congressional Medal of Honor.

May 10, 1968 - Peace talks begin in Paris but soon stall as the U.S. insists that North Vietnamese troops withdraw from the South, while the North Vietnamese insist on Viet Cong participation in a coalition government in South Vietnam. This marks the beginning of five years of on-again off-again official talks between the U.S. and North Vietnam in Paris.

June 5, 1968 - Robert F. Kennedy is shot and mortally wounded in Los Angeles just after winning the California Democratic presidential primary election.

July 1968 - Congress passes a ten percent income tax surcharge to defray the ballooning costs of the war.

July 1, 1968 - General Westmoreland is replaced as U.S. commander in Vietnam by General Creighton W. Abrams

July 1, 1968 - The Phoenix program is established to crush the secret Viet Cong infrastructure (VCI) in South Vietnam. The VCI, estimated at up to 70,000 Communist guerrillas, has been responsible for a long-standing campaign of terror against Americans, South Vietnamese government officials, village leaders and innocent civilians.

However, the Phoenix program, which is controlled through CORDS under the direction of Robert Komer, generates huge controversy in America concerning numerous alleged assassinations of suspected Viet Cong operatives by South Vietnamese trained by the U.S. The controversy, generated in part through North Vietnamese propaganda, eventually results in Congressional hearings. Testifying in 1971 before Congress, Komer's successor William E. Colby states, "The Phoenix program was not a program of assassination. The Phoenix program was a part of the overall pacification program." Colby admits that 20,587 Viet Cong had been killed "mostly in combat situations...by regular or paramilitary forces."

July 3, 1968 - Three American prisoners of war are released by Hanoi.

July 19, 1968 - President Johnson and South Vietnam's President Thieu meet in Hawaii.

August 8, 1968 - Richard M. Nixon is chosen as the Republican presidential candidate and promises "an honorable end to the war in Vietnam."

August 28, 1968 - During the Democratic national convention in Chicago, 10,000 anti-war protestors gather on downtown streets and are then confronted by 26,000 police and national guardsmen. The brutal crackdown is covered live on network TV. 800 demonstrators are injured.

The United States is now experiencing a level of social unrest unseen since the American Civil War era, a hundred years earlier. There have been 221 student protests at 101 colleges and universities thus far in 1968.

September 30, 1968 - The 900th U.S. aircraft is shot down over North Vietnam.

October 1968 - Operation Sealord begins the largest combined naval operation of the entire war as over 1200 U.S. Navy and South Vietnamese Navy gunboats and warships target NVA supply lines extending from Cambodia into the Mekong Delta. NVA supply camps in the Delta and along other waterways are also successfully disrupted during the two-year operation.

October 21, 1968 - The U.S. releases 14 North Vietnamese POWs.

October 27, 1968 - In London, 50,000 protest the war.

October 31, 1968 - Operation Rolling Thunder ends as President Johnson announces a complete halt of U.S. bombing of North Vietnam in the hope of restarting the peace talks.

Throughout the three and a half year bombing campaign, the U.S. dropped a million tons of bombs on North Vietnam, the equivalent of 800 tons per day, with little actual success in halting the flow of soldiers and supplies into the South or in damaging North Vietnamese morale. In fact, the opposite has occurred as the North Vietnamese have patriotically rallied around their Communist leaders as a result of the onslaught. By now, many towns south of Hanoi have been leveled with a U.S. estimate of 52,000 civilian deaths.

During Rolling Thunder, North Vietnam's sophisticated, Soviet-supplied air defense system managed to shoot down 922 U.S. aircraft during 2380 sorties flown by B-52 bombers and over 300,000 sorties by U.S. Navy and Air Force fighter-bombers.

November 1968 - William E. Colby replaces Robert Komer as head of CORDS.

November 5, 1968 - Republican Richard M. Nixon narrowly defeats Democrat Hubert Humphrey in the U.S. presidential election.

November 27, 1968 - President-elect Nixon asks Harvard professor Henry Kissinger to be his National Security Advisor. Kissinger accepts.

By year's end, U.S. troop levels reached 495,000 with 30,000 American deaths to date. In 1968, over a thousand a month were killed. An estimated 150,000 soldiers from North Vietnam infiltrated the South via the Ho Chi Minh trail in 1968. Although the U.S. conducted 200 air strikes each day against the trail in late 1968, up to 10,000 NVA supply trucks were en route at any given time.
