Khe Sanh Combat Base was a United States Marine Corps outpost south of the Vietnamese Demilitarized Zone (DMZ) used during the Vietnam War. ==History== Fighting began there in late April 1967 with the hill fights, which later expanded into the 1968 Battle of Khe Sanh. U.S. commanders hoped that the North Vietnamese Army would attempt to repeat their famous victory at the Battle of Dien Bien Phu, which would permit the U.S. to wield enormous air power. B-52s alone dropped more than 75,000 tons of bombs on the People's Army of Vietnam (PAVN) 304th and 325th Divisions encroaching the combat base in trenches. On April 1, 1968, the U.S. Army's 1st Cavalry Division launched Operation Pegasus to break the siege of the base. All three brigades from the 1st Cavalry participated in this vast airmobile operation, along with a Marine armor thrust.〔''Lurps: A Ranger's Diary of Tet, Khe Sanh, A Shau, and Quang Tri'', revised ed., Rowman & Littlefield Publishing Group, Lanham, MD (2009).〕 The defense of Khe Sanh commanded international attention and was considered the climactic phase of the Tet Offensive. On July 5, 1968, the combat base was abandoned, the U.S. Army citing the vulnerability of the base to dug-in enemy artillery positions in neutral Laos and the arrival of significant airmobile forces in I Corps (1st Cavalry and 101st Airborne Divisions). However, the closure permitted the 3rd Marine Division to conduct mobile operations along the DMZ. In 1971, Khe Sanh was reactivated by the U.S. Army (Operation Dewey Canyon II) to support Operation Lam Son 719, the South Vietnamese incursion into Laos. It was abandoned again in early April 1971.〔(DEPARTMENT OF THE ARMY - HEADQUARTERS - 8TH BATTALI0N (17MM/8 Inch) (SP), 4TH ARTILLERY, May 9th 1971 )〕〔(Khe Sanh Medal of Honor Awards - HAGEN, LOREN D. - 1Lt, US Army, Inf, US Army Training Advisory Group. )〕 On 27 January 1972 a U.S. Air Force AC-130A gunship was shot down by a PAVN SA-2 missile over the base. In March 1973, American intelligence reported that the PAVN had rebuilt the airstrip at Khe Sanh and were using it for courier flights into the South. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Khe Sanh Combat Base」の詳細全文を読む スポンサード リンク
