One VC was captured at (YD497341) with all equipment. Twelve VC KIA (body count) were credited to the Company during this sweep. Numerous other VC were fired at but exact body count was impossible due to close brush, absence of infantry support and close physical pursuit. The VC was sent back along the chain to the Company CP (YD505345). During the sweep, the combat CP came under VC sniper fire from (YD504346).

h. Civic Action.
(1) Medical Assistance. The Medical Contact Team of this com- mand dispensed a total of 477 medical treatments in the Hamlet of YEN BAC (AT985708). Medical coverage was also expanded to the CAM HOA Hamlet com- plex (AT970704). A total of 523 treatments and 13 dental extractions were affected in CAM HOA. Emergency medical assistance and evacuation was ren- dered to one Vietnamese National who has since been returned to the hamlet. Appoximately half of the treatments dispensed were in the "disease of the skin" and "upper respiratory infection" category.
(2) Agricultural Assistance. Assistance was rendered through the timely and effective distribution of some eight tons of fertilizer to the YEN BAC, CAM HOA Hamlet complex. An Animal Husbandry Team from USAID successfully vaccinated 67 pigs against smallpox and a Disease Control Team from Province Headquarters, QUANG NAM, vaccinated 10 water buffalo and 80 cows. An agricultural team also presented 150 assorted fruit trees to the two hamlet complex to diversify its agricultural spectrum. Ex- tensive repairs were made on the irrigation system of both hamlet. A Model "A" engine was coupled to a large capacity water pump which in conjunction with two other high capacity water pumps furnished by this command delivered an estimated five million gallons of water into the rice paddies of both hamlets. Two hundred kilos of "MUNK" peanuts were also distributed through the cooperation of USAID in an effort to improve local strains of peanuts. Classes were also given the villagers in the proper use of fertilizers and the operation and maintenance of irrigation pumps.

(3) Commodity Distribution. The distribution of commodities to both YEN BAC and CAM HOA included eight woodcarving kits, 120 school kits, 90 gallons of cooking oil, two physical education kits, 2,900 pounds of grain, assorted scrap lumber and building materials and seven boxes of writ- ing paper. Distribution was affected through the existing hamlet leader- ship according to the dictates of established custom. Distributed commod- ities were well received and led to a closer relationship between the two hamlets and this command.
(4) Area Security and Pacification was assisted through the continued employment of four Popular Forces soldiers by this command. At 0045 on 1 June 1966 a Viet Cong operative was killed in YEN BAC by security elements of this command while he was attempting to disseminate Viet Cong propaganda in the area. His presence seems indicative of the Viet Cong interest in disrupting the substantial gains made in the area through our Civic Action efforts. At 0015 on 4 June members of a security patrol accidential wounded a YEN BAC woman and killed her infant child. Immediate command attention prevented a serious "backlash" incident. An equitable settlement was made with the woman and no further ram- ifications resulted from the incident.
(5) Visitors to the CAM HOA and YEN BAC Hamlets during June included BrigGen ENGLISH accompanied by two New Zealand Officers, a CIB photographer, a reporter from the Honolulu ADVERTISER, and an NBC-TV camera team. While the latte was filming its report, a stray round, apparently from across the SONG CAU DO river, stuck and injured two Vietnamese Nationals. The entire incident was recorded on film and should make for some interesting viewing at some future date.
