Operation Kentucky was a multi-battalion operation conducted by the United States Marine Corps in the area south of the DMZ in Quảng Trị Province. This was another operation to secure the Con Thien area from the People's Army of Vietnam (PAVN). The operation ran from 1 November 1967 until 28 February 1969.
Following the conclusion of Operation Kingfisher, 3rd Marine Division split the Kingfisher tactical area of responsibility (TAOR) in two. The new Kentucky TAOR which included Firebase Gio Linh, Con Thien, Cam Lộ Combat Base and Đông Hà Combat Base (the area known to Marines as Leatherneck Square) was under the control of the 9th Marines, while to the west the Operation Lancaster TAOR covered Camp Carroll, The Rockpile and Ca Lu Combat Base was under the control of 3rd Marines.
On November 9 the Marines continued construction of the strongpoint obstacle system and engaged platoon and company-sized PAVN units, often in bunkers trying to ambush the Marines and hinder construction. The Marines killed 65 PAVN during these encounters. On 29 November 3 Marine Battalions and 2 Battalions from the Army of the Republic of Vietnam (ARVN) 1st Division conducted a clearing operation between Con Thien and Gio Linh. On 30 November 2/9 Marines found and overran a PAVN bunker system killing 41 PAVN for the loss of 15 Marines killed and 53 wounded.
This period saw relatively little PAVN activity other than harassment fire on the Con Thien base and the Marines used this relative quiet to continue to improve the strongpoints along the Trace line. On 31 December, Company I of 3/4 Marines on a patrol north from Strongpoint A-3 spotted PAVN soldiers in the southern DMZ, engaging the PAVN they soon realised that the PAVN occupied a line of bunkers in front of them. Marine mortars and artillery and two UH-1E Huey gunships from VMO-6 provided supporting fire and Company I was able to withdraw sustaining only 4 wounded, while the PAVN had lost at least 35 dead.
On the morning of 7 January while attempting to neutralise a PAVN sniper, two fire teams from Company L 3/4 Marines were ambushed. The remainder of Company L and Company K were sent in to help the fire teams break contact and were drawn into a daylong battle. By the end of the day the Marines had lost 6 killed, 36 wounded and 1 missing.
On 11 January a 3-Company operation was mounted to recover the body of the Marine missing in the 7 January operation, the PAVN had dragged the body into the DMZ and were using it as bait to trap US forces. The Marines supported by artillery and air strikes outflanked the PAVN positions, destroyed 25 bunkers and killed 15 PAVN for the loss of 2 Marines wounded.
On 18 January Company L 3/4 Marines launched a patrol 3.2 km northeast of Con Thien into an area nicknamed the Meat Market by Marines. The patrol was ambushed by PAVN in well-camouflaged bunkers and the lead squad was cut off from the rest of the Company and was used by the PAVN as bait for the other Marines. Under the cover of Marine gunships and artillery fire, the survivors and dead of the isolated squad were brought back into the Company perimeter. Company M then moved forward to relieve Company L and the combined force overran several PAVN bunkers. Marine losses were 9 dead and 22 wounded, while the PAVN were estimated to have suffered 100 casualties.
Due to the uncertainty of PAVN intentions in the DMZ, on 20 January COMUSMACV, General Westmoreland agreed to a request from III Marine Amphibious Force (III MAF) to suspend construction on the strongpoint obstacle system.
At 02:15 on 2 February the PAVN attacked the Combined Action Company P headquarters at Cam Lộ. The Marines, supported by a detachment of US Army M42 Dusters held off the PAVN attack until relieved by a quick reaction force from 2/9 Marines. The PAVN lost 111 killed and 23 captured while the Marines lost 2 dead and 18 wounded and the US Army lost 1 killed.
On 7 February the PAVN ambushed a patrol by a platoon from Company K 3/3 Marines south of Con Thien, killing 9 Marines including the Platoon Commander. The remainder of Company K moved to reinforce the ambushed platoon and were themselves ambushed from well-concealed PAVN bunkers, suffering 18 killed and 10 wounded in the first 5 minutes, including the Platoon commanders and their radio operators. At the 3/3 Marines operations center at Strongpoint A-3 the Battalion Commander ordered Company L to establish blocking positions while Company M manoeuvred to relieve Company K. Company M was unable to reach the ambush site before dark and Company L returned to Strongpoint A-3, while Companies K and M dug in for the night. On the morning of 8 February the two Companies, supported by tanks, artillery and gunships, attacked the PAVN bunker complex, killing 139 PAVN, while suffering a further 3 Marines killed.
Following their defeat in the Tet Offensive there was a marked decline in PAVN activity along the DMZ apart from ongoing artillery, rocket and mortar fire.
The PAVN continued to pressure the Marines particularly around the A-3 strongpoint between Con Thien and Gio Linh. On 3 March Company L, 3rd Battalion, 3rd Marines, occupying an outpost on Hill 28 just north of the A-3, intercepted a PAVN battalion attempting to infiltrate the Marine positions. The PAVN encircled the Marines and were only driven back by airstrikes and Huey gunship runs. One Marine was killed and thirteen wounded while killing over 100 PAVN.
On 16 March, Company M, 3/3 Marines and Company C, 1/4 Marines clashed with another battalion-sized PAVN force. The two Marine companies called in artillery and air upon the PAVN, the bulk of which disengaged, leaving a company behind to fight a rearguard action. PAVN artillery from north of the DMZ answered the American supporting arms with a 400-round barrage of its own on the Marines. Marine casualties were two killed and nine wounded for 83 NVA killed. For the entire month in Operation Kentucky, 9th Marines reported over 400 enemy dead while Marine casualties were 37 killed and more than 200 wounded.
On 22 May a patrol from Company A 1/4 Marines ran into a PAVN force east of Con Thien. 1/4 attacked east from Con Thien, while 3/3 Marines attacked west from Strongpoint A-3. 3/9 Marines were helicoptered into blocking positions in the south, while 1/9 Marines was helicoptered into blocking positions in the north. The PAVN tried to escape across the trace line but were mowed down by artillery, tank, gunship and fixed-wing fire. The PAVN suffered 225 killed, while the Marines had 23 killed and 75 wounded.
On 6 June, a reinforced platoon from Company E, 26th Marines observed and then engaged a PAVN company while on patrol 1.8 km southeast of Con Thien. Reinforced by the command group and a rifle platoon from Company H, the patrol engaged the PAVN with small arms and 81mm mortars. 14 PAVN were killed and the Marines suffered 14 killed and 11 wounded.
On 7 July, to exploit the results of Operation Thor in the Cửa Việt-Dong Ha sector, the 9th Marines began a sweep of the area between Con Thien and the DMZ. On 11 July, 4 km northeast of Con Thien, elements of 3/9 Marines discovered a reinforced PAVN platoon in the open. Fixing the PAVN in place with small arms fire, the Marines, with air, artillery, and tank support, launched a coordinated air-ground attack through the area killing more than 30 PAVN. The 9th Marines uncovered and destroyed numerous PAVN fortifications, a few of the positions were lightly defended, but the majority were abandoned. One bunker system discovered 4 km meters due north of Con Thien spanned more than 1 km and included 242 well-constructed bunkers. Supplies and equipment abandoned included weapons, 935 mortar rounds, 500 pounds of explosives, 55 antitank mines, and 500 pounds of rice. The Marines also found 29 bodies, killed by artillery and airstrikes during the advance on the complex.
On 21 July 2/9 Marines discovered a major PAVN bunker complex 6 km southwest of Con Thien. Composed of 60 A-frame timbered bunkers built into the sides of bomb craters, each with an average overhead cover 10-feet-thick, the system was connected to a large command bunker by a network of interconnecting tunnels. The command bunker featured an aperture overlooking Con Thien and C-2 and documents found in the bunker indicated that the PAVN had been observing and reporting the movement of helicopters, tanks, and trucks entering and leaving Con Thien and C-2.
Early August saw little contact with the PAVN other than an encounter by Company F, 9th Marines with 30 PAVN, 3 km east of Con Thien. In the face of artillery and fixed-wing support, the PAVN broke contact and the Marines began a sweep through the area during which they regained contact. The PAVN again broke and ran, and Company F moved through the area, capturing a number of weapons and counting 11 dead.
On 15 August, a PAVN company attacked a four-man Marine reconnaissance team southeast of Con Thien near the abandoned airstrip at Nam Đông. The patrol returned fire and requested reinforcement, while simultaneously calling in preplanned artillery fires. Within minutes a platoon from Company A, 1st Marines, accompanied by three tanks, moved out of positions 1 km away and headed south to assist. The coordinated attack, which included more than 150 rounds of 105mm artillery, 40 rounds of 4.2-inch mortar, 75 rounds from the 90mm guns of the tanks, and airstrikes by Marine UH-1E gunships accounted for several PAVN dead.
As PAVN activity continued to increase in the eastern DMZ, particularly north of Con Thien, the Marines decided to act. In addition to sightings of enemy tanks, Marine fighter pilots and aerial observers reported spotting trucks, truck parks, camouflaged revetments, storage bunkers, and trenchlines. Of special interest were repeated sightings of low, slow moving lights during hours of darkness which, it was assumed, came from enemy helicopters thought to be resupplying forward positions with high priority cargo such as ammunition and medical supplies or conducting medevacs. On 19 August, after 60 Arclight strikes 2nd Battalion, 1st Marines assaulted into three landing zones in the Trung Son region of the southern DMZ, 5 km north of Con Thien. Supported by a platoon of tanks from 3rd Tank Battalion, 2/1 Marines swept the area but found no evidence of use by VPAF helicopters. During the extraction one CH-46 Sea Knight was destroyed by a command detonated mine, killing 4 Marines.
While the assault claimed no PAVN casualties, it did scatter PAVN forces in the area. On the morning of the 19th, Bravo Company, 2/1 and the Army's Company A, 77th Armored Regiment engaged an enemy platoon while supported by M-48s from 3rd Tank Battalion, killing 26 PAVN. 6 km southwest of Con Thien Mike Company, 3/9 Marines intercepted a reinforced PAVN platoon, under the cover of airstrikes and artillery they kill 30 NVA and captured 2. On 20 August, 2 PAVN squads attacked Companies G and H, 2/9 Marines with small arms, RPGs, mortars, and artillery. The Marines, supported by 5 M-48s from 3rd Tank Battalion forced the PAVN to withdraw northward, leaving their dead. On 21 August, Company I, 9th Marines began receiving sniper fire and within an hour, the company had engaged a PAVN unit of undetermined size, firing small arms and grenades, responding with accurate rocket, mortar, and artillery fire, the Marines forced the PAVN to break contact and withdraw to the north. A search of the area found 14 PAVN dead and 12 weapons.
