Michelin Rubber Plantation was located near Dầu Tiếng District in Binh Duong Province, 72km northwest of Saigon. The plantation was established by the Michelin company in 1925[1] and at 12,400 ha it was the largest rubber plantation in Vietnam. The plantation was located approximately halfway between the Cambodia border and Saigon and so was an important base and staging area for the Vietcong and later the NVA. The plantation was an important source of revenue for the South Vietnamese Government and it was believed that the Michelin Company paid off the Vietcong in order to keep the plantation operating during the war. US forces were obliged to compensate Michelin for damage caused to the rubber trees during operations in the plantation.
US and ARVN forces conducted frequent operations against NVA and VC forces in the plantation. On the evening of 27 November 1965 the ARVN 7th Regiment, 5th Division was overrun by the VC 272nd Regiment, killing most of the Regiment and 5 US advisers[2][3]. From 21 to 27 February 1967 the 2nd and 3rd Brigades, 1st Infantry Division conducted Operation Mastiff, a search and destroy operation in and around the plantation[4]. From 22 February to 14 May 1967 3rd Brigade, 4th Infantry Division, 196th Infantry Brigade, 173rd Airborne Brigade, 11th Armored Cavalry Regiment, VNMC 1st and 5th Battalions and ARVN 35th and 36th Ranger Battalions conducted Operation Junction City which included operations in the plantation[5]. From 17 May to 7 December 1967, the 3rd Brigade, 25th Infantry Division conducted Operation Diamond Head, a search and destroy operation in the Plantation and surrounding areas[6]. In August and September 1968, popularly known as the Third Offensive in reference to the third wave of NVA attacks after the Tet Offensive the plantation was the scene of fighting between US forces and the NVA.
