The weather at Khe Sanh throughout February could be characterized in one word--miserable. General Tompkins remarked that, for combat purposes, the weather was the worst that he'd ever seen. The northeast monsoons had long since spilled over into the Khe Sanh Valley and every morning the base was shrouded with ground fog and low scud layers which dissipated around 1000 or 1100.

When the sun finally managed to burn through, the cloud ceiling retreated slightly but still hovered low enough to prevent the unrestricted use of airborne artillery spotters and strike aircraft. It was during these periods, when the overcast was between 100 and 500 feet, that enemy artillery, rocket, and mortar fire was the heaviest. The NVA forward observers, perched along the lower slopes of the surrounding hills, called in and adjusted barrages with little fear of retaliation against their own gun positions. Later in the afternoon, when the fog rolled in again and obscured the enemy's view, the incoming tapered off.(*)(114)
(*) The weather during February was bad for operations but not particularly uncomfortable. The mean temperature was 71 degrees the average humidity was 92 percent, and an average weekly rainfall was .04 inches. The wind was out of the east with an average velocity of 6 miles per hour.
The Marines adjusted their schedule accordingly. They usually worked under the cover of the haze in the morning, went underground during the midday shelling, and returned to their duties later in the afternoon. While the extremely low cloud cover occasionally befriended the men at the base, it constantly plagued the pilots whose mission was to resupply the 26th Marine
The job of transporting enough "bullets, beans, and bandages to sustain the 6,680 Khe Sanh defenders fell to the C-130s of Marine Aerial Refueler Transport Squadron 152 and the U. S. Air Force 834th Air Division; the C-123s of the 315th Air Commando Wing; the UH-34, Ch 46, and JH-lE helicopters of Marine Aircraft Group 36 (MAs-36); and the CH-53 choppers of MA -16.(**)(115)
(**) Organizationally, the USAF C-130s belonged to the 315th Air Division but that unit did not operate in Vietnam. Five to seven aircraft from each of the 315th's squadrons were on temporary duty in Vietnam and were under the operational control of the 834th Air Division. The 315th Air Commando Wing and its C-123s were organizationally part of the 834th.
Even under ideal circumstances, the airlift would have been a massive undertaking. The difficulties, however, were compounded by the poor visibility which was below minimum for airfield operations 40 percent of the time and the heavy volume of antiaircraft and artillery fire directed at the incoming transports. The NVA had moved several antiaircraft units into the hills east of the airstrip forcing the C-130 Hercules, the C-123 Providers, and the helicopters to run the gauntlet during their final approach.
Under cover of the heavy fog, some audacious NVA gun crews positioned their antiaircraft weapons just off the eastern threshold of the runway and fired in the blind whenever they heard the drone of incoming planes. Several aircraft were hit while on GCA final and completely in the soup.(*)(116)
(*) One NVA gun crew came in too close for its own good. The 1/26 commander, Lieutenant Colonel Wilkinson, dispatched a platoon from Company D to attack this position which was off the northeastern end of the airstrip. While the 81mm mortars of 1/26 provided support, the platoon commander, Second Lieutenant Daniel L. McGravey, and his men aggressively assaulted the position. During a brisk fire fight, they killed several North Vietnamese, captured the antiaircraft weapon, and took the gunne prisoner.
Immediately after touchdown, the aircraft were subjected to intense mortar and rocket fire; in fact, the incoming was so closely synchronized with their arrival, the fixed-wing transports were nicknamed "mortar magnets" by the Marines.(117)
The key to survival for the pilots was a steep approach through the eastern corridor, a short roll-out,and a speedy turnaround after landing. A small ramp paralleled the western end of the strip which the transport crews used as an unloading point. After roll-out, the pilot turned off the runway onto the easternmost taxiway, then wheeled onto the ramp while the loadmasters shoved the pallets of supplies out the back.(**)
(**) If a pilot made his approach from the west, which was not often the case, he had to taxi all the way back down the runway to the loading ramp.
All outgoing passengers were loaded on the double because the planes rarely stopped rolling. The pilot completed the loop by turning back onto the runway via the western taxiway and took off in the opposite direction from which he landed. It was not uncommon for the entire circuit to be completed within three minutes; even then, the planes were tracked by exploding mortar rounds.(118)
On 10 February, a tragedy occurred which resulted in a drastic alteration of the unloading process. A Marine C-130, heavily laden with bladders of fuel for the 26th Marines, was making its approach to the field under intense fire. Just before the giant bird touched down, the cockpit and fuel bags I were riddled by enemy bullets. With flames licking at one side, the stricken craft careened off the runway 3,100 feet from the approach end, spun around, and was rocked by several muffled explosions.
The C-130 then began to burn furiously. Crash crews rushed to the plane and started spraying it with foam. The pilot, Chief Warrant Officer Henry Wildfang, and his copilot suffered minor burns as they scrambled out the overhead hatch in the cockpit. Fire fighters in specially designed heat suits dashed into the flaming debris and pulled several injured crewmen and passengers to safety--rescue attempts came too late for six others.
One of those killed in the crash, Lieutenant Colonel Carl E. Peterson, the 1st MAW Engineer Officer, was a reserve officer who only a few months before had volunteered for active duty. As a result of this accident and damage sustained by other transports while on the ground, C-130 landings at Khe Sanh were suspended. (119)
LAPES
With the field closed to C-130s, a U. S. Air Force innovation--the Low Altitude Parachute Extraction System or LAPES--was put into effect. This self-contained system, which had been used extensively during the renovation of the airstrip in the fall of 1967, enabled the aircraft to unload their cargo without landing. When :making a LAPES run, the Hercules pilot made his approach from the east during which he opened the tail ramp and deployed a reefed cargo parachute.
Prior to touchdown, he added just enough power to hold the aircraft about five feet above the ground. As the plane skimmed over the runway and approached the intended extraction point, the pilot electrically opened the streaming chute which was attached to the roller-mounted cargo pallets. The sudden jolt of the blossoming chute snatched the cargo from the rear hatch and the pallets came to a skidding halt on the runway. The pilot then jammed the throttles to the firewall, eased back on the yoke, and executed a high-angle, westerly pull-out to avoid ground fire while the Marines moved onto the runway with forklifts and quickly gathered in the supplies.
The system was quite ingenious and allowed the aircraft to pass through the V-ring in a matter of seconds.(*)
(*) V-ring is a term used on the rifle range to describe the bull's-eye of a target.
Even though the airmen could not control the skidding pallets after release, some pilots perfected their individual technique and were able to place the cargo on a 25-meter square with consistency. On one occasion, however, an extraction chute malfunctioned and the cargo rocketed off the western end of the runway; the eight-ton pallet of lumber smashed into a mess hall located near the end of the strip and crushed three Marines to death. (120)
Another technique--the Ground Proximity Extraction System or GPES--was also used but to a lesser degree than the LAPES. (15 GPES deliveries during the siege as compared to 52 LAPES.) Both utilized the low approach but with GPES the cargo was extracted by a hook extended from a boom at the rear of the aircraft. As the C-130 swooped low over the runway, the pilot tried to snag an arresting cable similar to the one used on aircraft carriers; only his hook was attached to the cargo bundles and not the plane. Upon engagement, the pallets were jerked from the rear hatch and came to a dead stop on the runway.
With the GPES, the chance of a pallet skidding out of control or overturning was greatly reduced. The only problem that occurred was not with the system itself but with faulty installation. The Marines who initially emplaced the GPES were frequently chased away from their work by incoming mortar rounds and, as a result of the periodic interruptions, the cable was not anchored properly. The first C-130 that snagged the wire ripped the arresting gear out by the roots.
After the initial bugs were remedied, the system worked so successfully that, on one pass, a load containing 30 dozen eggs was extracted without a single eggshell being cracked. (121)
Most of the time, however, the low overcast precluded the use of eitherr extraction system and the preponderance of supplies was delivered by paradrops. This technique called for close air/ground coordination and the C-130 pilots relied on the Marine Air Traffic Control Unit (MATCU) at Khe Sanh to guide them in to the drop zones. The Marine ground controller lined the aircraft up on the long axis of the runway for a normal instrument approach and when the Hercules passed a certain point over the eastern threshold of the field, the controller called "Ready, Ready, Mark."
At "Mark," the pilot pushed a stop watch, activated his Doppler navigational system, turned to a predetermined heading and maintained an altitude of between 500 and 600 feet. The Doppler device indicated any deviation from the desired track to the drop zone, which was west of Red Sector, and the release point was calculated by using the stop watch--20 to 26 seconds from "Mark," depending on the winds.
At the computed release point, the pilot pulled the C-130 into an 8-degree noseup attitude and 16 parachute bundles, containing 15 tons of supplies, slid from the rear of the aircraft and floated through the overcast into the 300-meter-square drop zone. Under Visual Flight Rules MR), the average computed error for the drops was only 95 meters. Even when these missions were executed completely under Instrument Flight Rules (IFR), the average distance that the bundles landed from the intended impact point was 133 meters--well inside the drop zone.
On a few occasions, however, the parachute bundles missed the zone and drifted far enough away from the base to preclude a safe recovery. In these rare instances, friendly artillery and air strikes were brought to bear on the wayward containers to keep them from falling into the hands of the enemy. During the siege, Air Force C-130 crews conducted a total of 496 paradrops at Khe Sanh.(*)(122)
(*) Disparities in official records make it difficult to determine the exact tonnage delivered to Khe Sanh by air. The USAF Historical Division Liaison Office states that, of the 14,356 tons delivered during the siege, Air Force planes were responsible for 12,430 tons (8,120 tons by paradrop, LAPES and GPES; 4,310 by aircraft landing at the field). On the other hand, 1st Marine Aircraft Wing records show that Marine helicopters alone carried 4,661 tons of cargo. About three-fourths of the helicopter tonnage, however, was lifted directly from Dong Ha to the hill outposts and thus did not pass through the main base at Khe Sanh. Neither total includes the contributions made by Marine Aerial Refueler Transport Squadron 152; the records of that unit only indicate the tonnage transported throughout the whole of I Corps and do not break it down to the amount delivered to individual bases such as Khe Sanh.
Although the paradrops were sufficient for bulk commodities such as rations and ammunition, there were certain items which had to be delivered or picked up personally. Medical supplies, special ammunition, and other delicate cargo would not withstand the jolt of a parachute landing. In addition, there were replacements to be shuttled into the base and casualties to be evacuated.
With the cancellation of all C-130 landings, this job was left up to the sturdy C-123 Providers of the 315th Air Commando Wing as well as MAG-36 and MAG-16 helicopters. The choppers could maneuver around areas of heavy ground fire, land, unload, take on medevacs, and depart very quickly but their payloads were limited. On the other hand, the C-123s had a larger cargo capacity but were restricted to a more rigid approach and provided better targets both in the pattern and on the ground. (*)(123)
(*) This resulted in another fiery crash on 6 March when a C-123 was shot down while on approach to the field and all aboard (43 USMC, 1 USN, and 4 USAF) were killed.
The Providers, however, required much less runway from which to operate than the C-130s and could land and take off using only 1,400 of the 3,900 foot strip. This saving feature enabled the pilots to make a steep approach, short roll-out, and rapid turnaround. The crews still had to undergo those frantic moments on the ground when the geysers of dirty-black smoke bracketed their aircraft. Nevertheless, the dauntless C-123 crews continued their perilous missions throughout the siege with great success.(124)
No discussion of the airlift would be complete without mention of the MAG-36 and MAG-16 helicopter pilots who flew in and out of Khe Sanh daily delivering supplies, delicate cargo, reinforcements, and evacuating casualties. The chopper crews were faced with the same problems that plagued the fixed-wing transports--,low ceilings and enemy ground fire--but to a greater degree because of their slow speed and vulnerability. MRS-36 operated primarily from Quang Tri and Dong Ha, and was reinforced from the group's main base at Phu Bai. These valiant pilots and crewmen in their Huey gunships, CH-46 transports, and U11-34s flew long hours, day and night, in all kinds of weather to sustain the Marines in and around Khe Sanh, The CH-53s of Da Nang-based MAG-16, with their heavier payload, also made a sizeable contribution to this effort.(125)
The resupply of the hill outposts was a particularly hazardous aspect of the overall mission. Approximately 20 percent of Colonel Lownds' personnel occupied these redoubts and, for all practical purposes, were cut off from the rest of the garrison. The road north of the base was not secure and the perimeters atop the hills were too small and irregular for parachute drops; the only way that the isolated posts could be sustained was by helicopter. When the dense monsoon clouds rolled into the valley, the mountain tops were the first to become submerged and, as the overcast lifted, the last to reappear.

Right: UH-34 of MAG-36 leaves Khe Sanh on its way to hill outposts.
During February, several of the outposts were completely obscured for more than a week and resupply was impossible. During these periods, the North Vietnamese took advantage of the reduced visibility and emplaced heavy automatic weapons along the neighboring peaks and waited for the ceiling to lift which invariably heralded the arrival of helicopters. As a result, the UH-1Es, UH-34s, and CH-46s were subjected to a hail of enemy bullets during each mission.(126)
When the helicopters proceeded to the hills singly or in small groups, each mission was a hair-raising experience for both the chopper crews and the men on the ground. A good example of what often transpired during those frantic moments occurred early in the siege on Hill 831S when Captain Dabney called for a chopper to evacuate a badly wounded Marine.
One corporal was assigned as a stretcher bearer because he had a badly impacted wisdom tooth and, once aboard, he could ride out on the helicopter and have the tooth extracted at the main base.(*)
(*) Having the ambulatory cases serve as stretcher bearers was standard operating procedure on 881S. These men stayed on the chopper and did not have to make the return trip to their trenches under fire. When uninjured Marines served in this capacity there was the added danger that the helicopter would take off before they could debark and they would end up at Khe Sanh. In one instance after the siege was lifted, Captain Dabney spent a day at the combat base because he did not get off a medevac chopper fast enough.
Because of the 120mm mortars located in the Horseshoe and the antiaircraft guns which ringed the hill, the men on 881S had to employ a variety of diversions to keep the enemy gunners from getting the range of the incoming choppers. In this instance, they threw a smoke grenade a good distance away from the actual landing zone in hopes that the gunners would register on the smoke and the helicopter would be in and out before the North Vietnamese could readjust. .This meant that the helo had about 19 seconds to get off the ground.(127)
The ruse did not come off as planned. The stretcher bearers had barely loaded the wounded man aboard the helicopter, a CH46, when 120mm mortar rounds bracketed the aircraft and spurred the pilot to action. The helo lurched into the air and the sudden jolt rolled the corporal with the bad tooth over the edge of the tail ramp; he held on desperately for a few seconds but finally let go and fell about 20 feet to the ground. Cursing to himself, the young man limped back to his trench and waited for another chance.
Later that day, a UH-34 swooped in to pick up another casualty and the prospective dental patient quickly scrambled aboard. This trip also covered about 20 feet--10 feet up and 10 feet down--because the tail rotor of the UH-34 was literally sawed off by a burst from an enemy machine gun just after the bird became airborne. After the swirling craft came to rest, the passengers and the three-man crew quickly clamored out the hatch and dived into a nearby trench. A heavy mortar barrage ensued during which several more men were hit.
By the time another CH-46 arrived on the scene, the passenger list had grown to 14, including 10 casualties, the crew of the downed helo, and the original dental case. Because of the heavy concentration of enemy fire in the original zone, the Marines had blasted out another landing site on the opposite side of the hill. The chopper touched down and 13 of the 14 Marines boarded before the crew chief stated emphatically that the aircraft was full.
As luck would have it, the young Marine with the swollen jaw was the 14th man. Thoroughly indignant, the three-time loser returned to his position and mumbled that he would rather suffer from a toothache than try and get off the hill by helicopter.(*)(128)
(*) During the course of the battle, 881S became a small graveyard for helicopters; at least five were downed on or around the hill. Consequently, Company I gained a reputation among chopper crews which lasted long after the siege was over. When the 3d Battalion later departed Khe Sanh, Company I eventually moved to Hill 55 near Da Nang. One afternoon, while evacuating a wounded Marine, a CH-46 developed engine trouble and the pilot decided to shut down for repairs. Another flight was sent to pick up the wounded man and as the lead pilot approached he came up over the radio and asked his wingman where the landing zone was. The wingman replied: "Just look for the downed chopper, India /Company I/ always marks their zones that way."
It was the consensus of both the ground commanders and pilots alike that the problem of getting helicopters to and from the hills was becoming critical. The technique then employed was resulting in casualties among both the air crews and the infantry units, as well as a rapid rise in the attrition of MAG-36 helicopters. The Huey gunships, though putting forth a valiant effort, did not possess the heavy volume of fire required to keep the approach lanes open. As a result, the 1st MAW adopted another system which provided more muscle.(129)
The solution was basically a page out of the Fleet Marine Force Manual for Helicopter Support Operations. All helicopter flights to the hill outposts were to be escorted by strike aircraft which would provide suppressive fire. The A-4 Skyhawks of Chu Lai-based MAG-12 were selected as the fixed-wing escorts and the little jet was perfect for the job. Affectionately referred to as "Scooters" by their pilots, the A-4 was a highly maneuverable attack aircraft; its accuracy, dependability, and varied ordnance load had made it the workhorse of Marine close air support for many years.
Generals Cushman and Anderson conceived the idea and the details were worked out by Colonel Joel B. Bonner, Lieutenant Colonel William J. White, and Lieutenant Colonel Richard E. Carey at 1st MAW Headquarters. The operation went into effect on 24 February. Because of the large number of aircraft utilized in each mission--12 A-4s, 1 TA-4, 12 CH-46s,and 4 UH-1E gunships--the overall effort was nicknamed the Super Gaggle by its planners. The difficulty in execution was primarily one of coordination and control because of the various agencies (i.e. MAG-36, MAG-12, 3d MarDiv G-4, Dong Ha Logistics Support Area, and the units on the hill outposts) which were involved.
Additional factors that had to be considered were departure weather, destination weather, and coordination of friendly artillery and air strikes around Khe Sanh.
The Super Gaggle in Action
Lieutenant Colonel Carey, the 1st MAW Operations Officer and one of the planners, later described the mechanics of the Super Gaggle:
- Success of the effort was predicated on timing, coordination, and often times luck. Luck, as used, refers to the ability to guess whether the weather would hold long enough to complete an effort once it got underway. The effort began with the TA-4 on station determining if sufficient ceiling existed for the "Scooters" of MAG-12 to provide sufficient suppressive fires to assure success...
Once the TA-4 called all conditions go, an "H" hour was set and the Super Gaggle began. Twelve A-4s would launch from Chu Lai while simultaneously 100 miles to the north 12-16 helos would launch from the Quang Tri helo base and proceed to the Dong Ha LSA (Logistics Support Area) for supply pickup.
The object was for all aircraft to arrive in the objective area on a precise schedule. So the operation generally consisted as follows:
(1) Softening up known enemy positions by four A-4s, generally armed with napalm and bombs;
(2) Two A-4s armed with CS (tear gas) tanks saturate enemy anti-aircraft and automatic weapons positions;
(3) 30-40 seconds prior to final run in by the helos two A-4s lay a smoke screen along selected avenues of approach....
(4) While helos make final run into the target, four A-4s with bombs,rockets, and 20mm guns provide close-in fire suppression....
Once the helos commenced their descent the factors of weather, their 4,000-pound externally carried load, and the terrain would not permit a second chance. If an enemy gun was not suppressed there was no alternative for the helos but to continue. They (the transport pilots) were strengthened with the knowledge that following close on their heels were their gunships ready to pick them up if they survived being shot down. Fortunately, these tactics were so successful that during the entire period of the Super Gaggle only two CH-46s were downed enroute to the hill positions. The crews were rescued immediately by escorting Huey gunships.(*)(130)
(*) For comparison, as many as 16 helicopters were utilized up to four times in one day during the Super Gaggle without a loss. Prior to the conception of this technique, as many as three choppers were shot down in one day around Khe Sanh.
These-missions, however, looked much more orderly on paper than they did in the air and the operation lived up to its name, Only those who have experienced the hazards of monsoon flying can fully appreciate the veritable madhouse that often exists when large numbers of aircraft are confined to the restricted space beneath a low-hanging overcast. Coupled with this was the fact that the fluffy looking clouds around Khe Sanh housed mountains which ran up to 3,000 feet.
Top: CH-46 helicopters with 4,000-pound external loads head for outposs in a "Super Gaggle."
Bottom: A-4 Skyhawks of MaG-12 provide suppresive fire during resupply missions.
No doubt, the aircrews involved in the Gaggle were mindful of the standard warning issued to fledgling aviators: "Keep your eyes out of the cockpit; a mid-air collision could ruin your whole day." Even though the missions were well-coordinated and executed with a high degree of professionalism, it often appeared that confusion reigned because planes were everywhere. A-4s bore in on the flanks of the approach lanes blasting enemy gun positions and spewing protective smoke; CH-46s groped through the haze trying to find the landing zones; the hornet-like UH-1E gunships darted in from the rear in case someone was shot down; and the lone TA-4 circled overhead trying to keep his flock from running amuck.
During the missions to 881S, the men of India and Mike, 3/26, added to the hullabaloo with a little twist of their own. When the CH-46s settled over the hill, the Marines on the ground tossed out a few dozen smoke grenades for added cover and then every man in the perimeter fired a full magazine at anything on the surrounding slopes which appeared hostile. With some 350 men hosing down the countryside at the same time, the din was terrific.
Neither the deluge of lead from 881S nor the suppressive fire of the jets and gunships kept the NVA completely quiet. The 120mm mortar crews in the Horseshoe were especially active during the resupply runs to 881S and always lobbed some rounds onto the hill in hopes of knocking down a helicopter. These tubes had been previously registered on the LZs and the smoke screens had little effect on their fire; as a result, the Marines frequently shifted landing zones.(*)
(*) There is an interesting possibility as to why the mortars in the Horseshoe were never silenced. Fourteen years earlier, at Dien Bien Phu, the North Vietnamese used an ingenious method to protect their heavier siege mortars from air attacks and they may well have repeated it at Khe Sanh, The mortar crews selected a site on the slope of a hill, figured the elevation and deflection necessary to hit one specific target, and then dug a small tunnel at that precise angle into the side of the hill. The mortar was emplaced at the bottom of the tunnel with connecting caves which housed the gunners. When fired, the mortar rounds traveled up the shaft, sometimes as far as 50 feet before reaching the surface. The foliage was cleared away from the mouth of the tunnel so that the rounds did not hit the overhanging branches and detonate prematurely. Mortars emplaced in this manner were, of course, limited to only one target and, as far as the gunners in the Horseshoe were concerned, that target was 881S. When the siege was later broken and Marine units began to maneuver in the terrain surrounding the hill mass, they were never taken under fire by the 120mm mortars even though they did receive fire from smaller caliber weapons. Hill 881S, however, continued to be hit periodically by the 120mms.
The smoke did block the view of the North Vietnamese machine gunners and they were forced to fire blindly through the haze--if they dared fire at all. The choppers still took hits but nowhere near as many as before the Gaggle was initiated. The CH-46 pilots, poised precariously above the LZs during the few agonizing seconds it took to unload their cargo, often heard the sickening smack which meant that a bullet had torn into the fuselage of their thin-skinned helos.
The members of the two-man Helicopter Support Teams (HST), 3d Shore Party Battalion who were attached to the rifle companies were also prime targets. These men had to stand up while they guided the choppers into the LZs and, every few days, they had to attach bundles of cargo nets, which accumulated from previous missions, for the return trip to Dong Ha. This was dangerous for the aircrews as well as the HST men because, during the hook-up, the pilots had to hold their aircraft in a vulnerable position a few feet above the ground with the nose cocked up and the belly exposed to fire from the front.
While they attached the bundles, the ground support personnel could hear the machine gun rounds zing a few inches over their heads and slap into the soft underside of the suspended helicopter. Not all the bullets and shell fragments passed overhead; on 881S, the defenders were operating with their fourth HST when the siege ended.
No Harm, No Foul
In spite of the seriousness of the situation, the Gaggle was not without its lighter episodes. In one instance, an HST man attached to 1/3/26 hooked up an outgoing load and gave the pilot the "thumbs up" when he discovered that he had become entangled in the pile of nets. The CH-46 surged into the air with the startled Marine dangling helplessly from the bottom of the net by one foot. But for the quick reaction of his comrade on the ground who informed the pilot by radio that the chopper had taken on more than the prescribed load, the young cargo handler would have had a rather interesting trip to Dong Ha. The CH-46 crews also provided a human touch during these mission. When the Sea Knights swept over the hills, it was not uncommon to see a machine gunner on board quit his weapon for a second, nonchalantly pitch a case of soda pop out the hatch, and then quickly return to blaze away at the enemy positions.
At 1st MAW Headquarters, Lieutenant Colonel Carey, who had been an infantryman in Korea before he went to flight school and who sympathized with the men on the outposts, felt that a small gesture acknowledging their continued outstanding performance was in order. Special efforts were made to obtain quantities of dry ice for packing and one day, without notice, hundreds of Dixie-cups of ice cream were delivered to the men on the hill as part of the regular resupply.
This effort was dubbed Operation COOL IT. The only hitch developed on 881S where the Marines, unaware of the contents, allowed the cargo to remain in the LZ until after dark when it was safe to venture out of the trenches. The ice cream was a little sloppy but edible and greatly appreciated.
The introduction of the Super Gaggle was a turning point in the resupply effort. Prior to its conception, the Marines on the outposts dreaded the thought of leaving their positions to retrieve cargo--even when it included mail--because of the heavy shelling. With a dozen Skyhawks pasting the surrounding hills during each mission, this threat was alleviated to a large degree and casualties tapered off.
The Company I, 3/26, commander later stated: "If it weren't for the Gaggle, most of us probably wouldn't be here today." The helicopter pilots, knowing that their jet jockey compatriots were close at hand, were also able to do their job more effectively.
In the past, the transport crew chiefs occasionally had to jettison their external load prematurely when the pilot took evasive action to avoid ground fire. When this occurred, the cargo nets usually slammed into the perimeter and splattered containers all over the hilltop.(*)(131)
(*) Of all the jettisoned loads, those containing water were the most spectacular. On one occasion, a CH-46 carrying plastic containers of water was forced to release the net about 200 feet above the ground. The containers broke open in midair and the contents cascaded on the hill below. The Company P 2/26, commander, Captain Breeding,later recalled that it produced one of the prettiest waterfalls he'd ever seen.
With the Super Gaggle, the pilots had less enemy fire to contend with and did not bomb the hills with the cargo pallets as much; as a result more supplies arrived intact. In addition, the system greatly facilitated the picking up of wounded personnel. (**)
(**) It is no exaggeration to say that MAG-36 helicopters played a decisive role in the battle. The maintenance of the hill outposts was imperative if Khe Sanh was to be held, and these units depended on the helicopters for survival.
The Marine helicopters continued their flights to and from Khe Sanh throughout the siege. In spite of the obstacles, the chopper pilots crammed enough sorties into those days with flyable weather to haul 465 tons of supplies to the base during February. When the weather later cleared, this amount was increased to approximately 40 tons a day. While supporting Operation SCOTLAND, MAG-36 and MAG-16 flew 9,109 sorties, transported 14,562 passengers, and delivered 4,661 tons of cargo. (132)
Aerial Pipeline
Colonel Lownds was more than satisfied with the airborne pipeline which kept his cupboard full and he had quite a cupboard. The daily requirement for the 26th Marines to maintain normal operations had jumped from 60 tons in mid-January to roughly 185 tons when all five battalions were in place. While the defenders didn't live high off the hog on this amount, at no time were they desperately lacking the essentials for combat.
There were periods on the hills when the Marines either stretched their rations and water or went without, but they never ran short of ammunition. Understandably, ammunition had the highest priority--even higher than food and water. A man might not be able to eat a hand grenade but neither could he defend himself very effectively with a can of fruit cocktail. This did not mean that the men of the 26th Marines went hungry. On the average, the troops at the base received two C-Ration meals a day and this fare was occasionally supplemented with juice, pastry, hot soup, or fresh fruit.
The men on the hills subsisted almost entirely on C-Rations and the time between meals varied, depending on the weather. Within the compound, water was rationed only when the pump was out of commission and that was a rare occurrence. Lieutenant Colonel Heath's position on Hill 558 was flanked by two streams so 2/26 was well supplied but the Marines on the other four outposts depended on helilifts for water; it was used sparingly for drinking and cooking.(*)(133)
(*) During one period of extremely bad weather, the platoon from A/l/26 which held positions on Hill 950 went without re-supply for nine days and the water shortage became a major problem. Lieutenant Colonel Wilkinson authorized the platoon commander, Second Lieutenant Maxie R. Williams, to send a squad out to a small stream which was about two hours march from the perimeter. In addition to finding water, the Marines surprised a group of North Vietnamese and killed nine of the enemy. One Marine was also killed.
Besides the essentials, the 26th Marines also required tons of other supplies such as fortification material, fuel, tires, barbed wire, and spare parts--to name a few. PX items were on the bottom of the bottom of the priority totem pole because, as Colonel Lownds remarked: "If you have to, you can live without those."
On the other hand, mail had a priority second only to ammunition and rations. The men at Khe Sanh received over 43 tons of mail during the worst month of the siege.(134)
One portion of the airlift which affected morale as much as the arrival of mail was the swift departure of casualties. A man's efficiency was greatly improved by the knowledge that, if he were hit, he could expect immediate medical attention and when necessary, a speedy evacuation.(*)
(*) Bad weather occasionally precluded the immediate evacuation of casualties from the hill outposts.
Those with minor wounds were usually treated at the various battalion aid stations and returned to duty; the more seriously injured were taken to Company C, 3d Medical Battalion. Charley Med, as this detachment was called, was located just south of and adjacent to the aircraft loading ramp. There, U. S. Navy doctors and corpsmen treated the walking wounded, performed surgery, and prepared the litter cases for medevac. From Charley Med, it was a short, but often nerve-racking trip to a waiting aircraft and a hospital at Phu Bai. During the siege, the courageous men of Charley Med, often working under heavy enemy fire, treated and evacuated 852 wounded personnel.(135)
Thus the Marine and U. S. Air Force transport pilots, helicopter crews, loadmasters, and ground personnel kept open the giant umbilical cord which meant life for the combat base. Without their efforts, the story of Khe Sanh would undoubtedly have been an abbreviated edition with a not-too-happy ending. On the other hand, accounts of the heroism, ingenuity, and skill demonstrated by these men would fill a book. But there were other things besides mani-ia falling from the heavens at Khe Sanh and the vital role of the transports was frequently eclipsed by the efforts of air crews who carried a much deadlier cargo.
