The operation was a continuation of the recently concluded Operation Sam Houston in the same general area. 4th Infantry Division commander MG William R. Peers planned a defense in depth against People's Army of Vietnam (PAVN) incursions from Base Areas 701 and 702 across the Cambodian border.:290
Operation Francis Marion commenced on 6 April. The 1st Brigade, 4th Infantry Division deployed in an arc 20 km east of the Cambodian border along Highway 14B and the north-south line of U.S. Special Forces camps at Plei Djereng, Đức Cơ and Plei Me, with the 2nd Brigade held as a reserve force. Special Forces, CIDG units and the 4th Division's long-range reconnaissance teams would search the area west of this line to the Cambodian border. The Army of the Republic of Vietnam (ARVN) 23rd Division extended the screen south into Darlac Province and the 42nd Regiment of the 22nd Division extended it north into Kon Tum Province, split between Kon Tum city and Tân Cảnh Base Camp.:290
The operation saw isolated skirmishes in its first 2 weeks, then in mid-April Special Forces teams reported engaging a PAVN battalion in northern Darlac Province and several days later they reported sighting 2 PAVN companies 70 km south of Plei Me. In response to these reports on 24 April MG Peers sent a 1st Brigade battalion task force into northern Darlac Province.:290
On 28 April the 2nd Battalion, 8th Infantry Regiment patrolling north of Plei Me ambushed a group of PAVN killing 13 and the remainder fled into a fortified base camp. The 2/18th Infantry were unable to break through the PAVN defenses despite air and artillery strikes. The following morning, supported by 2 tanks and M113s they entered the camp but found it deserted. The force continued to advance, finding another base camp which was soon overrun by the tanks firing canister rounds, by mid-afternoon the battle was over, 138 PAVN soldiers from the 95B Regiment had been killed for the loss of 1 U.S. killed. On searching the base the 2/8th Infantry found 42 weapons, supplies and ammunition and a notebook detailing PAVN objectives for the rainy season offensive, including the 2nd Brigade base at Landing Zone Oasis and the Special Forces camps at Plei Djereng, Đức Cơ and Plei Me.:290–1
On 1 May a U.S. company repulsed a battalion-size attack near Đức Cơ. A prisoner revealed that 2 battalions of the 66th Regiment had recently arrived in the area around Đức Cơ and they planned to attack the Special Forces on 6 June, before attacking Plei Me.:291
Following 4 B-52 strikes southwest of Đức Cơ Camp, MG Peers sent the 1st Battalion, 8th Infantry in to search the area but they found no sign of PAVN activity.:291 On 13 May following a further B-52 strike 15 km northwest of Đức Cơ Camp, the 1/8th Infantry went in to search the area ending at Landing Zone Jackson Hole ( ), the 1st Brigade base on Highway 14B, with the 3rd Battalion, 12th Infantry Regiment moving parallel to it. On the morning of 18 May, Company B 1/8th Infantry patrolling in the densely jungled Ia Tchar Valley near the Cambodian border saw and pursued a lone PAVN soldier. The pursuit led the Company into an ambush by a large PAVN force and they formed a defensive perimeter while calling in air and artillery support, however the thick jungle canopy prevented aerial observation and absorbed much of the force of the incoming fire. The Battalion commander sent Company A to assist but the thick jungle delayed their progress. Company B's 4th platoon radioed that they were being overrun and called in artillery fire directly on their position. Company A was then moved by helicopter to Company B's position arriving just before sunset. The following morning Company A located Company B's 4th platoon, which had lost 19 killed, 1 missing and 7 wounded. The survivors said that after the PAVN overran the position they played dead while the PAVN executed those who moved. The rest of Company B lost had 10 killed and 24 wounded, while sweeps turned up 119 PAVN bodies. The PAVN were identified as being from the 32nd Regiment, which had last been seen in March 1967.:292–3
On 18 May a U.S. unit set up a night defensive position in an abandoned PAVN base camp. Shortly after dark, the PAVN began mortaring the position and then sent 3 assault waves against the position. The attack continued for several hours before the PAVN withdrew leaving 38 dead and 8 weapons, while U.S. losses were 10 killed. Four B-52 strikes were made on the surrounding area in the next 24 hours to deter any further attacks.:293–4
MG Peers moved the 3/12th Infantry into the Ia Tchar Valley to support the 1/8th Infantry and arranged for the 173rd Airborne Brigade to be moved in as reinforcements. On the morning of 24 May two companies of the 3/12th Infantry were about to break camp when they were hit by mortar fire and then attacked by a battalion-sized force. After 2 hours of fighting, low cloud in the area cleared allowing air support to break up the attack. U.S. losses were 10 killed while PAVN losses were 79 killed and 4 captured.:294
On 23 May it was decided to replace the 1/8th Infantry with the 3/8th Infantry. On 24 May as the 3/12th Infantry shuffled its companies, one understrength company was left alone to defend a hilltop landing zone when they were hit by a PAVN attack. Artillery fire was called in and a relief column sent and after an hour the PAVN withdrew leaving 37 dead, while U.S. losses were 4 killed.:294–5
On the morning of 26 May Company C, 3/8th Infantry was moving through thick jungle when it was hit by sniper fire killing the company commander and then hitting every officer in the company with a Master Sergeant having to take command and form a defensive perimeter. Company B sent 3 platoons to support Company C, only 1 of which was able to reach them, the others being stopped by intense fire. The PAVN launched several assaults, coming within 10m of the U.S. lines but were unable to penetrate and were eventually driven back by artillery and gunship fire leaving 96 dead and 2 wounded behind.:295–6
PAVN tactics were similar to those seen during Operation Sam Houston, the PAVN usually controlled the place and timing of the fighting, launching surprise attacks on units moving through jungle or in overnight positions, attacking with large amounts of mortar and RPG-2 fire and then withdrawing when American pressure became too great. Most of the engagements occurred close to the Cambodian border so the PAVN could withdraw to their cross-border sanctuaries as needed.:296–7
On 27 May MG Peers sent the 173rd Airborne Brigade into the Ia Drang Valley, but despite now having 3 brigades operating near the border the PAVN were still able to mortar Đức Cơ Camp on 19 and 23 June. In Kon Tum Province on 13 June the PAVN K101D Battalion attacked a CIDG unit 20 km southwest of Tan Canh and on 15 June they destroyed a Special Forces mobile guerilla force nearby. On 17 June MG Peers ordered the 173rd Airborne Brigade to reinforce Đắk Tô Base Camp.:296–7 This would mark the beginning of Operation Greeley, which would culminate in the Battle of Dak To in November 1967.:299
On 10 July 2 B-52 strikes took place between the Ia Drang Valley and Đức Cơ within 5 km of the Cambodian border and on 11 July the 1/12th Infantry was deployed to conduct bomb damage assessment of the area. The unit found no evidence of PAVN and moved 1 km east to set up 2 night defensive positions. On the morning of 12 July a patrolling platoon from Company C engaged a PAVN force killing 3, 30 minutes later Company C saw a larger PAVN force and called in artillery fire and ordered its patrol platoon to move to Company B's position, however the platoon then ran into another PAVN force and was soon surrounded. A platoon from Company B was sent to assist the Company C platoon and was similarly surrounded. Fog and low cloud prevented aerial observation and support until 11:00 and the isolated platoon relied on artillery support to avoid being overrun. Companies B and C were ordered to move to assist their beleaguered platoons but mortar fire hit the Company B command group killing the commander. Air and artillery support and reinforcements eventually forced the PAVN to abandon their attacks leaving 142 dead, U.S. losses were 31 dead and 7 missing (6 of whom became POWs and were returned in 1973) most of them from the Company B platoon.:304–6
On 23 July Companies B and C 3/8th Infantry were manning positions south of Đức Cơ, 10 km east of the Cambodian border. Each Company's 3 platoons were ordered to patrol the area to the west. At midday a platoon from Company C fired on 2 PAVN and were met by return fire from all directions, a second platoon was ordered to assist and was similarly pinned down. The PAVN then attacked the Company C command post and this was beaten back by helicopter gunships and reinforcement by Company B. The remainder of Company C backed by Company B, Company A and other reinforcements with strong air and artillery support then set out to rescue the 2 platoons, driving the PAVN 32nd Regiment back towards Cambodia. U.S. losses in the 5 hour battle were 18 killed, while PAVN losses were 184 killed by body count and 63 weapons captured.:306–7
On 3 August the PAVN ambushed a CIDG patrol 1 km from Dak Seang Camp and prisoner interrogations revealed that the newly arrived PAVN 174th Regiment planned to attack both Dak Seang and Dak Pek Camp. The ARVN airlifted a battalion of the 42nd Regiment and the 1st Airborne Task Force to Dak Seang and this force patrolled west from Dak Seang, where they encountered an entrenched battalion of the 174th Regiment. After a four-day battle and with heavy air support, the ARVN overran the position forcing the surviving defenders to flee into Laos. In the base were 189 PAVN dead, ammunition and equipment and a command post with a mock-up of the Dak Seang camp, which the PAVN apparently planned to attack on the night of 6 August.:303–4
Between 24 September and 10 October MG Peers deployed the 2nd Brigade to interdict PAVN infiltration through the Dak Payau Valley, southeast of Pleiku. On 1 October, helicopter gunships and tactical air support engaged a PAVN force moving along a trail, killing 49 by body count and taking 2 prisoners from the 95B Regiment.:309
The operation finally concluded on 11 October 1967. US forces claimed that PAVN losses were 1,600 killed, while U.S. losses were 300 killed and ARVN losses were 100 killed. The 1st Brigade, 4th Infantry Division continued to screen the border in western Pleiku Province, while 2nd Brigade continued east into Phu Bon Province to interdict PAVN infiltration.:309
The 173rd Airborne Brigade Combat Team (173rd ABCT) ("Sky Soldiers") is an airborne infantry brigade combat team of the United States Army based in Vicenza, Italy. It is the United States European Command's conventional airborne strategic response force for Europe.
Activated in 1915, as the 173rd Infantry Brigade, the unit saw service in World War II but is best known for its actions during the Vietnam War. The brigade was the first major United States Army ground formation deployed in Vietnam, serving there from 1965 to 1971 and losing almost 1,800 soldiers. Noted for its roles in Operation Hump and Operation Junction City, the 173d is best known for the Battle of Dak To, where it suffered heavy casualties in close combat with North Vietnamese forces. Brigade members received over 7,700 decorations, including more than 6,000 Purple Hearts. The brigade returned to the United States in 1972, where the 1st and 2d Battalion, 503d Infantry, were absorbed into the 3d Brigade, 101st Airborne Division (Airmobile), and the 3d Battalion, 319th Field Artillery was reassigned to Division Artillery in the 101st. The remaining units of the 173d were inactivated.
Since its reactivation in 2000, the brigade served five tours in the Middle East in support of the War on Terror. The 173d participated in the initial invasion of Iraq during Operation Iraqi Freedom in 2003, and had four tours in Afghanistan in support of Operation Enduring Freedom in 2005–06, 2007–08, 2009–10, and 2012–13. The brigade returned most recently from a deployment stretching from late 2013 to late 2014.
The 173rd Airborne Brigade Combat Team has received 21 campaign streamers and several unit awards, including the Presidential Unit Citation for its actions during the Battle of Dak To during the Vietnam War.1st Division (Vietnam)
The 1st Infantry Division was a division of the People's Army of Vietnam (PAVN), first formed from PAVN units in 1965.22nd Division (South Vietnam)
The 22nd Division of the Army of the Republic of Vietnam (ARVN) was part of the II Corps that oversaw the region of the central highlands north of the capital Saigon. The 22nd Division was based in Ba Gi near the south central coast.23rd Division (South Vietnam)
The 23rd Division of the Army of the Republic of Vietnam (ARVN)—the army of the nation state of South Vietnam that existed from 1955 to 1975—was part of the II Corps that oversaw the region of the central highlands north of the capital Saigon.Battle of Dak To
The Battle of Đắk Tô, also known as the Battle of Đắk Tô - Tân Cảnh (Vietnamese: Chiến dịch Đắk Tô - Tân Cảnh) in Vietnam, was a series of major engagements of the Vietnam War that took place between 3 and 23 November 1967, in Kon Tum Province, in the Central Highlands of the Republic of Vietnam (South Vietnam). The action at Đắk Tô was one of a series of People's Army of Vietnam (PAVN) offensive initiatives that began during the second half of the year. PAVN attacks at Lộc Ninh (in Bình Long Province), Song Be (in Phước Long Province), and at Con Thien and Khe Sanh, (in Quảng Trị Province), were other actions which, combined with Đắk Tô, became known as "the border battles." The post hoc purported objective of the PAVN forces was to distract American and South Vietnamese forces away from cities towards the borders in preparation for the Tet Offensive.
During the summer of 1967, heavy contact with PAVN forces in the area prompted the launching of Operation Greeley, a combined search and destroy effort by elements of the U.S. Army's 4th Infantry Division and 173rd Airborne Brigade, along with the Army of the Republic of Vietnam (ARVN)'s 42nd Infantry Regiment and RVN airborne units. The fighting was intense and lasted into the fall, when the PAVN seemingly withdrew.
By late October, however, U.S. intelligence indicated that local communist units had been reinforced and combined into the PAVN 1st Division, which was tasked with the capture of Đắk Tô and the destruction of a brigade-size U.S. unit. Information provided by a PAVN defector provided the allies a good indication of the locations of PAVN forces. This intelligence prompted the launching of Operation MacArthur, and brought the units back to the area along with more reinforcements from the ARVN Airborne Division. The battles that erupted on the hill masses south and southeast of Đắk Tô became some of the hardest-fought and bloodiest battles of the Vietnam War.List of allied military operations of the Vietnam War (1967)

The following outline is provided as an overview of and topical guide to the Vietnam War:
Vietnam War – Cold War-era proxy war that occurred in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. This war followed the First Indochina War (1946–54) and was fought between North Vietnam—supported by the Soviet Union, China and other communist allies—and the government of South Vietnam—supported by the United States, Philippines and other anti-communist allies. The Viet Cong (also known as the National Liberation Front, or NLF), a South Vietnamese communist common front aided by the North, fought a guerrilla war against anti-communist forces in the region. The People's Army of Vietnam, also known as the North Vietnamese Army (NVA), engaged in a more conventional war, at times committing large units to battle.
