When night had fully fallen, and after our meager evening rations had been doled out, Julian and I once more made our way toward the docks. The warehouse, though still heavily guarded, was less busy at this hour. The men Julian had chosen as his workforce had been sworn to secrecy, and they slept apart from the other soldiers so as not to risk unwise conversation. Most of the recruits, Julian said, knew only the particular task assigned them, and had been kept ignorant of the whole outline of the business. But there were a hundred or so men who had been made to understand our ultimate objective, and this elite group was in the warehouse tonight—or rather on top of the warehouse, for we climbed an iron stairway to the roof of the building, which was securely tiled and only gently sloped. The “Kite Brigade,” as Julian called them, awaited him there.
The night was moonless, the stars obscured by high fast-running clouds. Apart from a few campfires, and lanterns in odd windows, the town of Striver was entirely dark. The huge kites I had seen before had been brought up here. They were still furled, but their bridles had been attached to reels of hempen twine which were nailed to wooden bases and equipped with hand cranks. Each kite also had a bucket tied to its bridle with a short string, and as we arrived a man was just finishing the work of pouring a measured amount of sand into each of these buckets.
“What’s that for?” I asked Julian—quietly, since the eerie atmosphere of the rooftop seemed to discourage anything beyond a hushed whisper.
“I’ve calculated how much weight each parafoil can carry,” Julian said. “To night we discover whether my calculations were correct.”
I didn’t ask how one estimated the lifting power of a “parafoil,” or with what kind of arithmetic—no doubt it was something else Julian had learned from one of his antique books. If it depended on the wind, we were in luck; the breeze was brisk; but it was very cold, and I kept my hands in the pockets of my overcoat, and wished I had my old packle hat on top of my head, instead of the thin Army cap I was wearing.
Everything seemed ready for the “test flight,” as Julian called it, except for the darkness. “How can you see whether they fly, when the moon is down and even the Northern Lights aren’t operating?”
Julian didn’t answer, but beckoned to a man nearby. This soldier carried a bin with some liquid in it, and a brush.
The liquid, as it turned out, was a compound of phosphorous which radiated an unearthly green light. [The Dutch use it for military signaling, but it also serves in theatrical effects.]
The soldier employed his brush to splash a little of this on each bucket, until they had all been so marked, and glowed like demonic jack-o’-lanterns in the darkness.
“Stringmen prepare!” Julian called out abruptly.
Dozens of men jumped to their stations at the anchored kite-reels.
“Furlers stand ready!”
An equal number of men, positioned downwind along the rim of the roof, grasped the huge furled kites and held them at present-arms, ready to be unrolled so that their wings might catch the wind.
“Launch!” cried Julian.
The reader should understand that a black silk kite taller than a man, lofted into the Stygian darkness of a Labrador night, while the wind comes skirling from the arctic regions like a madman with a knife in his teeth, is not the same beast as a child’s kite bobbing in the sunlight of a summer day. The immense black kites, though not easily visible, made their presence known as soon as the first one caught the icy breeze and opened with a concussive bang as loud as a gunshot.
Each kite, as the wind filled it, made the same deafening report (which reminded me of the popping of sails aboard the Basilisk when that vessel began to trim for heavy weather), until it sounded as if an artillery duel was under way and we were in the middle of it. Then the kites rose to the limit of the strings which bound them to the buckets they were meant to carry, each with its weighed portion of sand and its glowing green insigne.
Evidently Julian’s calculations had been correct. With only a moment’s hesitation, and an encouraging tug from the Stringmen, the buckets soared aloft. Mere words cannot convey how unusual and strange this looked: all that was visible from any distance was the phosphorescent paint that marked each rising container. These unearthly Lights (as they seemed) rose and bobbed and rose again, like angels or demons sailing in close formation. I was suffused with awe, even though I knew the explanation for what I was seeing. An unenlightened observer might easily have been terrified.
“Not every American soldier in town is asleep,” I said. “Might not someone see this, and alert others?”
“I hope so. It will brace up the men, to think that this is a sample of what we’ve been preparing.”
“They’ll take it for supernatural.”
“Let them take it according to their beliefs—it makes no difference.”
“But—as impressive as this is—a kite isn’t a weapon, Julian, even if it flies at night and glitters like an owl’s eye.”
“Sometimes seeming is as good as being.” Julian busied himself with a sort of sextant, performing an act he called “triangulation.” By this time the kites had come to the end of their measured lengths of tether. The tether-lines were taut; in fact the Stringmen had to struggle to keep the reels in place, so powerful was the force generated by the wind upon the parafoils. The hempen lines strained ferociously, and made a singing noise, eerie in the darkness.
Julian spent some time instructing the Stringmen on how to buck and lax their lines so that the kites could be made to drop and rise again. They performed the task crudely, but Julian reckoned that even a little experience was better than none. Then the Stringmen began the slow and laborious task of reeling the kites back from the sky.
An impressive display, but it wasn’t finished—Julian had one more theatrical effect he wished to test.
“Tubemen ready!” he shouted.
Another group of soldiers, who had previously been huddled at the chimney-brace for warmth, suddenly separated and formed into a row. Each of them carried a length of rubber tubing, perhaps originally intended to transport water in some Dutch governor’s mansion. When they had room enough—much to my amazement—they began to whirl the tubes above their heads, the way a cattle-herder might whirl a rope, though less elegantly. The result was that each tube (and they had been cut to various lengths) began to sing, much the way an organ-pipe sings when wind is blasted through it. What the performance yielded in this circumstance was not music, however, but a kind of unearthly, dissonant hooting—the sound a chorus of loons might make, if they were inflated to the size of elephants.
I had to clap my hands over my ears. “Julian, the whole town will be awake—you’ll wake up the Dutch infantry, though their trenches are miles away!”
“Good!” said Julian; or at least that’s what he appeared to say; the keening of the rubber tubes drowned him out somewhat. But he smiled contentedly, and after a time made a hand signal that caused the Tubemen to cease their whirling. By this time the black kites were almost reeled in, and before long the whole production was over.
No more than an hour had passed.
My astonishment was boundless, but I told Julian I still could not see the point of it. The Dutch troops, if we tried this trick on them, would no doubt be impressed —quite possibly frightened —but it didn’t seem to me they would be materially damaged in any way.
“Wait and find out,” said Julian.
