Dak To
In the Summer of 1967, the 4th Infantry Division's 1st and 2nd Brigades were making heavy contact with enemy forces in the Central Highlands of Vietnam, in western Kontum Province. These heavy enemy contacts prompted division commander Lieutenant General William R. Peers to request reinforcement and, as a result, on 17 June, two battalions of Brigadier General John R. Deane's 173rd Airborne Brigade were moved into the Dak To area to begin sweeping the jungle-covered mountains in Operation Greeley. The 173rd had been operating near Bien Hoa Air Base outside Saigon and had been in combat only against NLF guerrillas. Prior to its deployment to the highlands, Peer's operations officer, Colonel William J. Livsey, attempted to warn the Airborne officers of the hazards of campaigning in the highlands. He also advised them that PAVN regulars were a much better equipped and motivated force than the NLF. These warnings, however, made little impression on the paratroopers, who were about to become victims of their own overconfidence.
On 20 June, Charlie Company, 1st Battalion, 503rd Airborne Infantry (C/1/503) discovered the bodies of a Special Forces CIDG unit that had been missing for four days on Hill 1338, the dominant hill mass south of Dak To. Supported by Alpha Company, the Americans moved up the hill and set up for the night. At 06:58 the following morning, Alpha Company began moving alone up a ridge finger and triggered an ambush by the 6th Battalion of the 24th PAVN Regiment. Charlie Company was ordered to go to support, but heavy vegetation and difficult terrain made movement extremely difficult. Artillery support was rendered ineffective by the limited range of visibility. Close air support was impossible for the same reasons. Alpha Company managed to survive repeated attacks throughout the day and night, but the cost was heavy. Of the 137 men that comprised the unit, 76 had been killed and another 23 wounded. A search of the battlefield revealed only 15 dead North Vietnamese.
In response to the destruction of Alpha Company, MACV ordered additional forces into the area. On 23 June, the 1st Battalion, 1st Brigade, 1st Air Cavalry Division arrived to bolster the 173rd. The following day, the Army of the Republic of Vietnam's (ARVN) elite 1st Airborne Task Force (the 5th and 8th Battalions) and the 3rd Brigade of the 1st Air Cavalry Division arrived to conduct search and destroy operations north and northeast of Kontum. General Deane sent his forces 20 kilometres (12 mi) west and southwest of Dak To to search for the 24th PAVN Regiment. By October, the 173rd, the 4th Infantry Division, and six ARVN battalions were moved to Dak To. The North Vietnamese Army, in turn, had moved almost 6,000 troops in four infantry regiments and one artillery regiment.
The battle around Dak To became more costly as 4th Battalion of the 173rd was ordered to occupy Hill 823, south of Ben Het, for the construction of Fire Support Base. Only the battalion's B Company was available for the attack, which was borne by helicopter. The company was able to take the hill but suffered 9 dead and 28 wounded. The following morning Bravo Company was relieved by Lieutenant Colonel David J. Schumacher's 1/503, which (against the admonitions of Colonel Livsey) was divided into two small task forces. Task Force Black consisted of Charlie Company supported by two platoons of Dog Company and Task Force Blue which was composed of Alpha Company and the remaining platoon of Dog. Task Force Black left Hill 823 to find the North Vietnamese who had attacked B/4/403. At 08:28 on 11 November, after leaving their overnight laager and following a PAVN communications wire, the force was ambushed by the 8th and 9th Battalions of the 66th PAVN Regiment and had to fight for its life. Task Force Blue and Charlie Company 4/503 drew the job of going to the relief of the beleaguered task force. They encountered fire from all sides during the relief attempt, but they made it, reaching the trapped men at 15:37. U.S. losses were 20 killed, 154 wounded, and two missing.
Following an attack on the Dak To airbase, and actions on hill 882 by the 1/503rd that saw 7 men dead and 34 wounded, 330 men of 2/503 moved in to assault Hill 875. At 10:30, as the Americans moved to within 300 metres (984 ft) of the crest, PAVN machine gunners opened fire on the advancing paratroopers. Then B-40 rockets and 57 mm recoilless rifle fire were unleashed upon them. The paratroopers attempted to continue the advance, but the North Vietnamese, well concealed in interconnected bunkers and trenches, opened fire with small arms and grenades. At 14:30 PAVN troops hidden at the bottom of the hill launched a massed assault from the rear. Unknown to the Americans, they had walked into a carefully prepared ambush by the 2nd Battalion of the 174th PAVN Regiment. Soon, U.S. air strikes and artillery fire were being called in, but they had little effect on the battle because of the dense foliage on the hillside. Resupply became a necessity because of high ammunition expenditures and lack of water, but it was also an impossibility. Six UH-1 helicopters were shot down or badly damaged that afternoon trying to get to 2/503.
The next morning the three companies of 4/503 were chosen to set out and relieve the men on Hill 875. Because of intense PAVN sniper and mortar fire (and the terrain) it took until nightfall for the relief force to reach the beleaguered battalion. On the afternoon of 21 November both battalions moved out to take the crest. During fierce, close-quarters fighting, some of the paratroopers made it into the PAVN trenchline but were ordered to pull back as darkness fell.
The following day was spent in launching airstrikes and a heavy artillery bombardment against the hilltop, totally denuding it of cover. On 23 November, the 2nd and 4th Battalions of the 503rd were ordered to renew their assault while the 1st Battalion of the 12th Infantry assaulted 875 from the south. This time the Americans gained the crest, but the North Vietnamese had already abandoned their positions, leaving only a few dozen charred bodies and weapons.
The battle of Hill 875 had cost 2/503 87 killed, 130 wounded, and three missing. 4/503 suffered 28 killed 123 wounded, and four missing. Combined with noncombatant losses, this represented one-fifth of the 173rd Airborne Brigade's total strength. For its combined actions during operations around Dak To, the 173rd Airborne Brigade was awarded the Presidential Unit Citation. 340 of the 570 173rd Airborne troops who attacked the hill become casualties.
