The village of Nuo Hoy, whose population we suspected had participated in the looting, lay twelve miles to the west, amidst densely forested hills. It was plausible to suppose that the sheer quantity of the stolen material had made it imperative for the enemy to establish several secret dumps. They could not have possibly stored everything in their camp, not with any degree of safety. Natural caves and runnels, either in the hills or beneath the village, were the likely places to look for.
Pondering over the map, we reasoned that the camp itself should be located within a limited area, since to sustain several hundred men the enemy needed plenty of water. A small stream fed by a creek from the mountains flowed through the suspected village. The creek was the only natural source of water in the hilly area. The terrorist camp ought to be somewhere along that creek. We settled for investigating the neighborhood of the village, without revealing ourselves to the enemy. Naturally we could not follow the existing trails that were probably mined and kept under constant surveillance. Although it meant a detour of thirty miles, the alternative route had more appeal for me. It was prudent to suppose that the stockade was still under enemy observation and that Viet Minh lookouts were watching our activities.
We left the compound late in the afternoon when it was still light enough for the snoopers to see us moving in the opposite direction, away from them and our true destination. As soon as darkness prevented further observation we entered the woods and camped down for the night. For all intents and purposes, our battalion had vanished from the sight of the enemy. Now we were on equal terms with the Viet Minh and even had a slight advantage, for we knew where we wanted to strike next but they had no idea where we were.
Shortly after sunrise we set out for the hills. Our trail-blazers needed four days to cut a path through the virgin woods and arrive within two miles of the village. Xuey, Schenk, and four men departed on a long reconnaissance trip into the hills south of the settlement, where I suspected the guerrillas had had their camp along the creek. The sky was overcast and it appeared as if a storm was in the making. We established ourselves a mile inside the woods, close to a brook but high enough not to be washed away by a sudden downpour. It began to rain shortly afterwards and poured for almost a day without stopping. Cooking was out of the question, save for an occasional cup of tea or a soup made of extracts. The men were able to prepare these in their canteens by burning spirit cubes under the protection of their burlaps. We were carrying no tents except for a few canvas sheets to protect our radio gear, maps, and sensitive equipment.
The rain came down so hard that it penetrated the overhead foliage like bullets, and we had to seek shelter among the trees and under thick branches. Wild torrents of water rushed down from every direction and emptied into the brook, which became a thundering river. Several times we had to move to safer spots but even so the men were soon in deep mud and could not even sit down properly. The roaring of the rain as it hammered on the leaves around us was so intense that we had to shout to make ourselves understood. By evening our small canteens of rum had been consumed. With it went our only source of warmth. A period of constant shivering now began. The troops swallowed aspirin and sulfathiazole pills to head off illness.
Suoi fared better. When the rain started, she put on a long sleek nylon raincoat with a hood. Now she sat on the rucksacks, her head resting in Erich’s lap. He was holding a sandwich for her to bite.
“An idyllic spectacle,” Eisner commented. But I had to concede that she put up with all our hardships bravely. And I wondered how Xuey, Sergeant Schenk, and the party were faring out in the hills, for they carried not even burlaps.
Toward morning the rain abated. The clouds drifted off and the sun began to shine. The temperature rose rapidly. By eleven o’clock the forest had turned into a steam-bath. Stripped to the waist, the troops were strolling off left and right, searching for small patches of sunlight to dry their damp clothes and to warm their chilled bones. The day was spent cleaning weapons, greasing footwear, and learning Indochinese. Ever since Suoi joined our battalion, linguistic studies had gained popularity among the troops. Suoi was a charming and patient teacher and from the moment she took charge of our language courses progress was certain.
The reconnaissance party brought back good news. Sergeant Schenk had discovered the Viet Minh camp and had made a diagram of the area. There was a small cascade in the hills which supplied the enemy camp with water. From a cliff above the cascade, Schenk and Xuey observed the camp for over two hours. Xuey was certain that it sheltered both Nam Hoa and Trengh, along with approximately five hundred terrorists. The camp, Schenk explained, was so cleverly arranged that it was almost impossible to move a large body of troops against it. Save for the one cliff, which could accommodate not more than ten men at a time, there were no other places where troops or automatic weapons could be deployed. The dense vegetation prohibited the use of machine guns elsewhere, and to enter the camp one had to pass along a narrow ravine which the Viet Minh covered with machine guns.
But if the location of the camp prohibited the use of troops and weapons, it certainly invited our bag of rat poison. The creek that fed the Viet Minh water tank could be approached unseen from above. I decided to leave the village alone for the time being but occupy the surrounding hills and trails with a couple of strong detachments. The majority of the troops were to remain with Eisner, Riedl, and Pfirstenhammer to conclude the first phase of the operation—the envelopment of the whole area. Selecting only fifty men, Schulze and I planned to establish a camp close to the guerrilla base, within easy reach of the cascade.
Starting out before daybreak, we broke up into separate groups and proceeded with the occupation of the hills. Suoi insisted on joining Schulze and me and after a brief argument, I bowed to the majority vote. We crossed the stream and the road three miles west of the village, following the trail which Xuey and Schenk had already surveyed. Leaving Suoi with the men in a secluded depression, Xuey, Schenk, Schulze, and I proceeded to the cliff and settled down near the precipice, where jutting boulders covered with shrubs permitted us to survey the enemy base at leisure.
The creek came from high above in the hills. Cold and clear, it flowed past where we were hidden and dropped steeply between the rocks, forming a small cascade a hundred feet below. Near the cascade stood a large water tank made of tin. A circular lid covered the top and it had several taps at the bottom. A system of hollow bamboo served as pipes to convey water from a smaller arm of the cascade to the tank. The tube could be swiveled to and from the water and it was now disconnected. Using canvas bags we dissolved the sack of arsenic in water and added our supply of morphine, digitalis, and a few other drugs to the mixture. Sergeant Zeisl was sure that our cocktail could kill a herd of elephants.
Our major problem was how to convey the preparation to the small branch of the cascade that fed the tank. It would have been of little use to drop the poison into the cascade for only a fraction of it would have reached the branch and consequently the tank. Schulze came up with the idea of using a hollow bamboo to funnel down the poison. There was no bamboo around and Sergeant Schenk had to fetch some from a thicket two miles away.
We occupied the only accessible position in the neighborhood, but the camp was so cleverly hidden among the trees that even we could see only four or five huts. Nearest the tank stood the cooking house, where fires burned in carefully shielded earthen ovens. The overhead foliage was extremely dense, and instead of rising, the smoke dispersed before it reached the treetops. Air reconnaissance could never spot the base, which seemed fairly well established and contained all the necessary components of a permanent base. The mess hut housed a long row of tables made from the sides of ammunition crates which had been nailed to poles driven into the ground. The benches had been contrived in a similar fashion. Along the creek we noticed a spacious natural pool which served as a bath. Farther downstream a couple of empty crates stood in the water, weighed down with boulders; they served as washing stands.
