At first it seemed that the petrol trench would serve its purpose. The besiegers sensed the peril of swimming it, and made no move to plunge blindly over its brink. Instead they devised a better maneuver; they began to collect shreds of bark, twigs and dried leaves and dropped these into the petrol. Everything green, which could have been similarly used, had long since been eaten. After a time, though, a long procession could be seen bringing from the west the tamarind leaves used as rafts the day before.
Since the petrol, unlike the water in the outer ditch, was perfectly still, the refuse stayed where it was thrown. It was several hours before the ants succeeded in covering an appreciable part of the surface. At length, however, they were ready to proceed to a direct attack.
Their storm troops swarmed down the concrete side, scrambled over the supporting surface of twigs and leaves, and impelled these over the few remaining streaks of open petrol until tlhey reached the other side. Then they began to climb up this to make straight for the helpless garrison.
During the entire offensive, the planter sat peacefully, watching them with interest, but not stirring a muscle. Moreover, he had ordered his men not to disturb in any way whatever the advancing horde. So they squatted listlessly along the bank of the ditch and waited for a sign from the boss. The petrol was now covered with ants. A few had climbed the inner concrete wall and were scurrying towards the defenders.
“Everyone back from the ditch!” roared Leiningen. The men rushed away, without the slightest idea of his plan. He stooped forward and cautiously dropped into the ditch a stone which split the floating carpet and its living freight, to reveal a gleaming patch of petrol. A match spurted, sank down to the oily surface–Leiningen sprang back; in a flash a towering rampart of fire encompassed the garrison.
This spectacular and instant repulse threw the Indians into ecstasy. They applauded, yelled and stamped, like children at a pantomime. Had it not been for the awe in which they held the boss, they would infallibly have carried him shoulder high.
It was some time before the petrol burned down to the bed of the ditch, and the wall of smoke and flame began to lower. The ants had retreated in a wide circle from the devastation, and innumerable charred fragments along the outer bank showed that the flames had spread from the holocaust in the ditch well into the ranks beyond, where they had wrought havoc far and wide.
Yet the perseverance of the ants was by no means broken; indeed, each setback seemed only to whet it. The concrete cooled, the flicker of the dying flames wavered and vanished, petrol from the second tank poured into the trench–and the ants marched forward anew to the attack.
The foregoing scene repeated itself in every detail, except that on this occasion less time was needed to bridge the ditch, for the petrol was now already filmed by a layer of ash. Once again they withdrew; once again petrol flowed into the ditch. Would the creatures never learn that their self-sacrifice was utterly senseless? It really was senseless, wasn’t it? Yes, of course it was senseless–provided the defenders had an unlimited supply of petrol.
When Leiningen reached this stage of reasoning, he felt for the first time since the arrival of the ants that his confidence was deserting him. His skin began to creep; he loosened his collar. Once the devils were over the trench there wasn’t a chance in hell for him and his men. God, what a prospect, to be eaten alive like that!
For the third time the flames immolated the attacking troops, and burned down to extinction. Yet the ants were coming on again as if nothing had happened. And meanwhile Leiningen had made a discovery that chilled him to the bone-petrol was no longer flowing into the ditch. Something must be blocking the outflow pipe of the third and last cistern-a snake or a dead rat? Whatever it was, the ants could be held off no longer, unless petrol could by some method be led from the cistern into the ditch.
Then Leiningen remembered that in an outhouse nearby were two old disused fire engines. Spry as never before in their lives, the peons dragged them out of the shed, connected their pumps to the cistern, uncoiled and laid the hose. They were just in time to aim a stream of petrol at a column of ants that had already crossed and drive them back down the incline into the ditch. Once more an oily girdle surrounded the garrison, once more it was possible to hold the position–for the moment.
It was obvious, however, that this last resource meant only the postponement of defeat and death. A few of the peons fell on their knees and began to pray; others, shrieking insanely, fired their revolvers at the black, advancing masses, as if they felt their despair was pitiful enough to sway fate itself to mercy.
At length, two of the men’s nerves broke: Leiningen saw a naked Indian leap over the north side of the petrol trench, quickly followed by a second. They sprinted with incredible speed towards the river. But their fleetness did not save them; long before they could attain the rafts, the enemy covered their bodies from head to foot.
In the agony of their torment, both sprang blindly into the wide river, where enemies no less sinister awaited them. Wild screams of mortal anguish informed the breathless onlookers that crocodiles and sword-toothed piranhas were no less ravenous than ants, and even nimbler in reaching their prey.
In spite of this bloody warning, more and more men showed they were making up their minds to run the blockade. Anything, even a fight midstream against alligators, seemed better than powerlessly waiting for death to come and slowly consume their living bodies.
Leiningen flogged his brain till it reeled. Was there nothing on earth could sweep this devil’s spawn back into the hell from which it came?
Then out of the inferno of his bewilderment rose a terrifying inspiration. Yes, one hope remained, and one alone. It might be possible to dam the great river completely, so that its waters would fill not only the water ditch but overflow into the entire gigantic “saucer” of land in which lay the plantation.
The far bank of the river was too high for the waters to escape that way. The stone breakwater ran between the river and the plantation; its only gaps occurred where the “horseshoe” ends of the water ditch passed into the river. So its waters would not only be forced to inundate into the plantation, they would also be held there by the breakwater until they rose to its own high level. In half an hour, perhaps even earlier, the plantation and its hostile army of occupation would be flooded.
The ranch house and outbuildings stood upon rising ground. Their foundations were higher than the breakwater, so the flood would not reach them. And any remaining ants trying to ascend the slope could be repulsed by petrol.
It was possible–yes, if one could only get to the dam! A distance of nearly two miles lay between the ranch house and the weir–two miles of ants. Those two peons had managed only a fifth of that distance at the cost of their lives. Was there an Indian daring enough after that to run the gauntlet five times as far? Hardly likely; and if there were, his prospect of getting back was almost nil.
No, there was only one thing for it, he’d have to make the attempt himself; he might just as well be running as sitting still, anyway, when the ants finally got him. Besides, there was a bit of a chance. Perhaps the ants weren’t so almighty, after all; perhaps he had allowed the mass suggestion of that evil black throng to hypnotize him, just as a snake fascinates and overpowers.
The ants were building their bridges. Leiningen got up on a chair. “Hey, lads, listen to me!” he cried. Slowly and listlessly, from all sides of the trench, the men began to shuffle towards him, the apathy of death already stamped on their faces.
“Listen, lads!” he shouted. “You’re frightened of those beggars, but you’re a damn sight more frightened of me, and I’m proud of you. There’s still a chance to save our lives–by flooding the plantation from the river. Now one of you might manage to get as far as the weir–but he’d never come back. Well, I’m not going to let you try it; if I did I’d be worse than one of those ants. No, I called the tune, and now I’m going to pay the piper.
