9. Operation Rolling Thunder

10. In early 1965, U.S. President Lyndon Johnson ordered the first of many sustained bombing missions over North Vietnam, which would be known as Operation Rolling Thunder (began on March 2, 1965 and lasted until the end of October 1968). --100 US Air Force planes and 60 South Vietnamese planes. -- In all, the US flies 304,000 fighter bomber sorties and 2,380 B-52 bomber sorties over North Vietnam, loses 922 aircraft and drops 634,000 tons of bombs. In March of the same year, the first U.S. combat troops were sent to Vietnam.

At first, Army combat units played a defensive role, protecting Saigon, the South Vietnamese capital, and other important cities and bases.

The newly formed U.S. Army, Vietnam managed the logistical effort.

16. Tools of the trade for a tunnel rat.

17. Tunnell Rats Matters escalated when three North Vietnam PT boats launched an attack against the U.S.S. Maddox, an American ship engaged in a reconnaissance mission in international waters in the Gulf of Tonkin, on August 2, 1964. The American ship fights off the PT boats, which launch 3 torpedos, none of which strike the Maddox. On August 3, the Maddox is joined by the U.S.Turner Joy in the Gulf. That night, it is reported that the Turner Joy was attacked. The NSA in 2005 issued a report that the second attack never happened. In the U.S. Congress, August 10 th - the Gulf of Tonkin Resolution was passed, allowing for an expanded war effort. --authorized the President to "take all necessary measures" to repel attacks against US forces and to "prevent further aggression" in the area.The Resolution provided President Johnson with a blank check to take whatever action he deemed appropriate in South Vietnam.

19. Tet Offensive American fortunes changed for the worse with the Tet Offensive in 1968, in which major South Vietnam cities and the U.S. embassy in Saigon were simultaneously attacked. It took nearly two weeks to completely rout the VC troops. The North Vietnamese lost an estimated 10,000 men and did not hold on to any of their objectives; however, historians disagree on the literal success of the offensive, but it proved to be a huge boost for North Vietnamese morale, and had the opposite effect on the South Vietnamese and U.S. forces.

21. As American service members fought in Vietnam, a different kind of war was taking place for American citizens back home, where the struggle was between the American people and their opposition to the fighting in Vietnam; and the American presidency's (beginning with J.F.K.) determination to halt the spread of communism.

26. However, the South Vietnamese continued to battle the Communists from March 1973 until the fall of Saigon and the capture of the South Vietnamese presidential palace on April 30, 1975, which brought the war to a close.

27. So divisive was the conflict in Vietnam and America's involvement that relations among the government, the people and the military would be strained until they were reunified by the Gulf War 25 years later. As evidenced by numerous documentaries, books and films about the war, the hard lessons the U.S. learned in Vietnam are still very much in the public consciousness.

28. Consequences 58,000 lives and 350,000 American casualties. Between one and two million Vietnamese deaths. Congress enacted the War Powers Act in 1973.
