First Indochina War At the end of the
First Indochina War, in June 1954, the
French Army Groupe Mobile 100 was ordered to fall back from
An Khê to Pleiku and then to reopen Route Coloniale 14 between Pleiku and
Buôn Ma Thuột. This led to the last battle of the war: the
Battle of Mang Yang Pass.
Second Indochina War Pleiku was strategically important during the
Vietnam War because it was the primary terminus of the military supply logistics corridor extending westwards along Highway 19 from the coastal population centre and port facilities of
Qui Nhơn. Additionally, its central location on the plateau, between Kon Tum to the North,
Buôn Ma Thuột to the south, and the
North Vietnamese Army's base areas inside
Cambodia to the west made Pleiku the main centre of defense of the entire highland region of the
Republic of Vietnam. This was obvious to both sides; the
United States established an armed presence very early in the conflict at
Camp Holloway, and the
Việt Cộng attack on this base in early 1965 was one of the key escalating events that brought U.S. troops into the conflict. On 15 June 1972,
Cathay Pacific Flight 700Z, operating a
Convair 880 (VR-HFZ) from Bangkok to Hong Kong, disintegrated and crashed while the aircraft was flying at 29,000 feet (8,800 m) over Pleiku, Vietnam after a bomb exploded in a suitcase placed under a seat in the cabin, killing all 81 people on board. After the fall of Buôn Ma Thuột to a major North Vietnamese assault in early 1975, and the resulting insecurity of
National Route 19 leading from
Qui Nhơn, the president,
Nguyễn Văn Thiệu, ordered the hasty evacuation of Pleiku. The military operation to attempt the withdrawal of ARVN forces, down the poorly maintained tertiary road LTL-7B through
Ayun Pa to
Tuy Hòa, led to a catastrophe in which over 100,000 evacuees from Pleiku and Kon Tum were killed or left stranded without support. == Geography ==
