Low Level Hell

The aeroscouts of the 1st Infantry Division had three words emblazoned on their unit patch: Low Level Hell. It was then and continues today as the perfect concise definition of what these intrepid aviators experienced as they ranged the skies of Vietnam from the Cambodian border to the Iron Triangle. The Outcasts, as they were known, flew low and slow, aerial eyes of the division in search of the enemy. Too often for longevity’s sake they found the Viet Cong and the fight was on. These young pilots (19-22 years old) “invented” the book as they went along.

Praise for Low Level Hell

“An absolutely splendid and engrossing book. The most compelling part is the accounts of his many air-to-ground engagements. There were moments when I literally held my breath.”—Dr. Charles H. Cureton, Chief Historian, U.S. Army Training and Doctrine (TRADOC) Command

“Low Level Hell is the best ‘bird’s eye view’ of the helicopter war in Vietnam in print today. No volume better describes the feelings from the cockpit. Mills has captured the realities of a select group of aviators who shot craps with death on every mission.”—R.S. Maxham, Director, U.S. Army Aviation Museum

CHAPTER 1       
THUNDER ROAD
 
South Vietnam, July 1969
 
“Phu Loi tower, this is Darkhorse One Six. I've got a hunter-killer team on the cav pad. North departure to Lai Khe.”
 
“Roger, Darkhorse One Six flight of two. You're cleared to hover.”
 
Cobra pilot Dean Sinor (Three One) and I were heading up to Thunder Road to provide aerial cover to a heavy northbound supply convoy. A scout and gun team ran ahead of convoys coming out of Lai Khe to run a low-level inspection of the entire road up to An Loc. Even though dismounted engineer and infantry swept the highway for mines every morning at first light, this stretch of road had proved highly susceptible to ambush attack.
 
With Sinor at altitude, I put my Loach down low and slow, to pick up anything out of place on or along the road. It was possible for the enemy to get in and plant a few mines between the time it was swept by the engineers and the arrival of the convoy. Early in the morning, once the highway had been swept by the engineers, civilian traffic was always bustling along Thunder Road—motorcycles, mopeds, carts, Cushman-type vehicles, little buses, and small trucks. But never before the U.S. Army had cleared the road for mines. It was far too dangerous.
 
Working about a mile ahead of the convoy, I headed straight down the highway, banked to the east, then back south to check the cleared area on the column's right flank. I cut west over the last vehicle and headed back north to check out the left side of the convoy, creating a boxlike search pattern.
 
On my first run back along the east side of the road, I saw evidence of recent heavy foot traffic, enough to make me feel very uneasy. I didn't see any enemy, so I headed across the tail end of the convoy to make my run back north on the west flank.
 
As I got about six hundred yards out ahead of the column, I picked up heavy foot trails again. There wasn't any good reason for people to have been out in the Rome-plowed area next to the highway, so I decided to follow one of the trails to see where it took me. It led to a drainage ditch that stretched for nearly a mile—right along the side of the highway! But, again, not a single person in sight.
 
Circling over the area, I keyed the intercom to my crew chief. “Parker, do you see anything? Something's damned screwy about this. What do you make of it?”
 
“Don't see anything but footprints, Lieutenant. Not a soul, sir!”
 
About that time I made a sharp turn over a thick clump of tall grass on the west side of the road near the drainage ditch, about ten feet from the side of the highway. Not more than four to five feet below me, I glimpsed a slight movement and something dark lying on the ground.
 
“Son of a bitch, Jim! Did you see that?” I hollered into the intercom.
 
I hauled the Loach around to hover right above the spot. Then Parker and I saw the two dark brown eyes staring up at us from a hole dug into the ground under an area of pushed-up dirt created by the Rome plow months before.
 
Without me saying a word, Jim Parker opened up. I winced at the explosion of the M-60 right behind my head. The enemy soldier jerked violently and slumped over in his hole.
 
I got on the radio to Sinor. “Three One, One Six. We got a dink. The gunner shot a dink dug into the grass up under a Rome plow mound, not more than ten feet off the west side of the highway. I think they're all over the place—up close, not in the jungle! They've dug in spider holes right on top of the convoy!”
 
The head of the convoy was just seconds away at this point, heading right into an ambush. Sinor immediately called the convoy commander on FM.
 
The minute the convoy commander got the word that the enemy was close to him, I knew he would order all convoy weapons to open up on both sides of the highway, and woe be to the Loach pilot who was out there when all that ordnance started to go off.
 
Three One knew it too. “Get the hell out of there, One Six,” he yelled. “Get up to altitude, NOW!”
 
But which way can I go? I thought. No time to get any altitude. And I can't go parallel to the convoy, or I'll make myself a tailor-made flank shot for every gun—ours and theirs. So I pulled the hardest right turn I could, made a 180-degree arc, and headed back south again—right on top of the northbound convoy. I figured the safest place for a Loach at that moment was five feet off the tops of those trucks, where hot rounds would least likely be crisscrossing.
 
I barely made it on top of the convoy when all hell broke loose. The enemy, now fully alerted by Parker's shooting of the soldier in the spider hole, sprung its ambush. They pushed aside the overhead camouflage and rose up out of their holes, guns blazing. At point-blank range, they opened up into the convoy with everything they had: AK-47s, RPGs, grenades, SGMs. The column simultaneously let go with their machine guns, 90mm cannon firing canister rounds, and every other weapon carried on the vehicles in the convoy. It was like one giant, sustained explosion. Bullets flew everywhere. Deafening noise erupted. Smoke and flying debris engulfed the entire convoy. And there, in the midst of that sudden hell, were Parker and me flying at antenna level, straight down the back of the convoy, trying our best to stay out of the way of both enemy and friendly fire.
 
As the convoy charged north, we flew south, blistering along at well over one hundred knots, Parker working with his M-60 from the right side of the aircraft. His tracers were impacting on the spider holes as we ripped past, his targets not more than ten to twenty yards from his muzzle. We were so low that if someone had reached up out of a truck or tank turret, they probably could have caught our skid.
 
Suddenly, not more than a hundred yards to my front, a five-thousand-gallon tanker truck took a direct RPG hit, and the diesel fuel it was carrying exploded like a nuclear bomb. Sheets of flame, parts of the truck, smoke, and dust shot up, momentarily blinding me. The little OH-6 lurched violently with the shock of the explosion, as though a giant unseen fist had landed a smashing blow to the nose of the aircraft.
 
I jerked aft as hard as I could on the cyclic and yanked in a load of collective. The resulting g's nearly sent my buttocks through the armor plate in the bottom of my seat. I don't know how Parker was able to hang on.
 
As the fast-reacting Loach wrenched up over the eruption, I said silently, “God bless this helicopter!” then yelled to Sinor over UHF: “Three One, One Six. I'm coming up to altitude. We're OK, but that was close! You're cleared in. I'm out of the way. Hit the tree line to the west of the convoy.”
 
The battle between Charlie and the convoy continued with ferocity. Shortly after the tanker truck exploded, a five-ton rig near the middle of the convoy was hit. It was loaded with ammunition—enough to knock everything around it off the road. Then a tank went up, its turret flying into the air fifteen to twenty feet, turning a somersault, and crashing back down.
 
The convoy's intent was to continue moving north as fast as it could, and it managed to do just that. If a vehicle was hit, the driver made every attempt to get it off the road under its own power. If it was hit too badly to move itself out of the way, the driver behind rammed it and pushed it off. The key was to break free of the killing zone and accelerate out of the ambush area, while pumping all possible fire into the ambushers to gain fire superiority.
 
The enemy's RPGs did the most damage. Once a vehicle was disabled with rocket fire, the automatic weapons would open up. Charlie had prepared well; he was hitting hard from a position of advantage.
 
When the enemy had lost the element of surprise and the defenders began to gain the firepower advantage, the enemy troops usually would attempt to break contact and fade into the jungle before an organized pursuit could be launched. With this in mind, I keyed Sinor as he pulled out of his rocket and minigun run along the western line. “Three One, let's cut off the avenue of retreat. Work up some artillery and give us two brackets of artillery fire on both sides of the road running north and south. We'll pin them against the highway with no back door.”
