b. LRRP Team "Wild Cat" - provided long reconnaissance patrol in the Phuong Dinh district.

8. (C) General:
a. On 24 July 1968, the enemy initiated an attack against the Phuong Dinh (3) Military District compound (BT 540608), located approximately 1000 meters northwest of FSB Picarelli.
b. The Viet Cong attack on Phuong Dinh began at 240113 July and terminated approximately 240630 July. American advisors who were in the compound kept the Brigade TOC informed of the attack as it commenced, developed and terminated. This information was retransmitted to the Americal Division TOC as it was received. Per request of the ARVN Commander and American advisors for our assistance, the Brigade requested division's approval to form Joint Task Force (Americal, 25th ID and 1st CAV) with LRRP detachment from 1st ID and move elements into the Phuong Dinh area to assist the compound. The Brigade's requests, to employ units in the area were disapproved because the ROK Marine Brigade located southeast of the Suoi Bao Ao River was preparing to assist the compound and exploit the area of operations. However, the 198th Brigade provided direct support artillery fires for targets in the vicinity of the Phuong Dinh compound. Subsequent operations were conducted by the new formed Joint Task Force to search-and-destroy the enemy as he withdrew from the Phuong Dinh District area into the Joint Task Force TAOR.

9. (C) Intelligence:
a. Weather:
(1) The weather conditions during the period of 25 to 31 July 1968 were: generally no cloudy skies without rain, high humidity and even temperatures averaging 96F maximum and 82F minimum.
(2) Effects on enemy operations: Periods of reduced visibility favored undetected movement by enemy units.
(3) Effects on our operations: Periods of reduced visibility which made it difficult to locate and identify enemy targets negated the employment of Air Force flareships and miniguns as well as Army gunships (armed helicopters) during all the operation.

b. Terrain: The terrain in the area of operations is generally flat and contains many rice paddies and several streams formed by the Suoi Bao Ao River. Open fields are covered with elephant grass and brushwood. There is also "tree line" of Asian pines at BT520580.

c. Enemy:
(1) Numerous intelligence reports indicated that the enemy had improved his strength and increased his activities northwest of the FSB Picarelli at Phuong Dinh (3) (BT 540608), northeast at east bank of Suoi Bao Ao River (BT565609) and southwest at abandoned airfield (BT 526569). The intelligence liaison officer of the 198th LIB reported several times that the Phuong Dinh (3) Military compound could be attacked by one or two companies of the 72nd VC Bn. The American Advisory team at Phuong Dinh (3) acted on the intelligence reports and began preparation to increase the defensive posture of the complex; foliage was cut down and claymore mines were installed. Coordination with ROK Marines and the 198th Bde was made for the employment of artillery defensive concentrations and H&I fires. Two nights prior to the attack the ROK's provided the artillery fires.

10. (C) Missions:
a. Provide security for and defend the abandoned airfield and prevent or defend against attacks from that area toward Phuong Dinh (3).
b. Per request of Phuong Dinh Advisor (while under attack): provide artillery and gunship support in defense of Phuong Dinh compound.
c. Provide security for and defend FSB Picarelli against enemy attack.
