March 30-May 1 - The siege at Dien BienPhu occurs as nearly 10,000 French soldiers are trapped by 45,000 VietMinh. French troops soon run out of fresh water and medical supplies.

The French urgently appeal to Washington for help. The U.S. Joint Chiefsof Staff now consider three possible military options: sending Americancombat troops to the rescue; a massive conventional air strike by B-29bombers; the use of tactical atomic weapons.

President Eisenhower dismisses the conventional air raid and the nuclearoption after getting a strong negative response to such actions from America'schief ally, Britain.

October 1954 - Following the French departurefrom Hanoi, Ho Chi Minh returns after spending eight years hiding in thejungle and formally takes control of North Vietnam.

In the South, Bao Dai has installed Ngo Dinh Diem as his prime minister.The U.S. now pins its hopes on anti-Communist Diem for a democratic SouthVietnam. It is Diem, however, who predicts "another more deadly war"will erupt over the future of Vietnam.

Diem, a Roman Catholic in an overwhelmingly Buddhistcountry, encourages Vietnamese Catholics living in Communist North Vietnamto flee south. Nearly one million leave.

"The cost of defending freedom, ofdefending America, must be paid in many forms and in many places...militaryas well as economic help is currently needed in Vietnam," Eisenhowerstates.

Diem's government, however, with its main focus on security, spendslittle on schools, medical care or other badly needed social services inthe countryside. Communist guerrillas and propagandists in the countrysidecapitalize on this by making simple promises of land reform and a betterstandard of living to gain popular support among peasants.

The trail will eventually expand into a 1500 mile-longnetwork of jungle and mountain passes extending from North Vietnam's coastalong Vietnam's western border through Laos, parts of Cambodia, funnelinga constant stream of soldiers and supplies into the highlands of SouthVietnam. In 1959, it takes six months to make the journey, by 1968 it willtake only six weeks due to road improvements by North Vietnamese laborers,many of whom are women.

April 1960 - Eighteendistinguished nationalists in South Vietnam send a petition to PresidentDiem advocating that he reform his rigid, family-run, and increasinglycorrupt, government. Diem ignores their advice and instead closes severalopposition newspapers and arrests journalists and intellectuals.

November 1960 - A failed coup against PresidentDiem by disgruntled South Vietnamese Army officers brings a harsh crackdownagainst all perceived 'enemies of the state.' Over 50,000 are arrestedby police controlled by Diem's brother Nhu with many innocent civilianstortured then executed. This results in further erosion of popular supportfor Diem.

Thousands who fear arrest flee to North Vietnam. Ho Chi Minh will latersend many back to infiltrate South Vietnam as part of his People's LiberationArmed Forces. Called Viet Cong by Diem, meaning Communist Vietnamese, Ho'sguerrillas blend into the countryside, indistinguishable from South Vietnamese,while working to undermine Diem's government.
