“Sorry, Captain,” said Murchison, “I spoke without thinking.”
The other nodded and went on. “The damage may already have been done. They’ve seen our ship fly, and the med-station buildings, and we checked their first attack by throwing sand at them and threatening to douse them with seawater, although neither stopped them trying to attack us because it was the rainstorm that did that. Maybe they think we were responsible for that, too. But allowing them to run into an invisible wall like the meteorite shield could be too much for a primitive species to take, brave and resourceful and adaptable though they are.
“The trouble is,” it went on, “that we can’t generate clouds of sand under the trees and neither can we drag water that far without it spilling on the way. We can use more power on the tractor to uproot trees and throw soil into the air, but not with enough accuracy to keep some of the spiders from getting squashed. Pathologist Murchison, didn’t you mention earlier that they had a fear of fire as well as water?”
“I did,” Murchison replied, “but I’d rather you didn’t use it because I’m not sure whether the on-board fire precautions I saw were due to the material of their ships being flammable, or their bodies.”
“My idea is to frighten them off without hurting them,” said the captain. “Don’t worry, I’ll be careful. But I’d like them to come close enough for Dr. Priliclato get an emotional reading from them. Specifically, why do they feel so strongly about us that they are willing to go up against a completely strange and obviously superior enemy?”
For nearly an hour they watched the enhanced images of the spider force as it moved slowly nearer, making use of all available cover and spreading out into line abreast formation as it came. The captain said complimentary things about the spider commander’s tactical know-how as the center of the line held back to enable the formation to form a crescent that would enclose the station and the grounded Rhabwar. They had closed to just under one hundred meters before the captain spoke directly to the station.
“Dr. Prilicla, are they close enough to give you an emotional reading?”
“Yes, friend Fletcher,” he replied, “a strong but imprecise one. The strength as well as the lack of precision is due to the large number of sources sharing the same feelings. There is uncertainty and apprehension characteristic of fear that is under control, and a general feeling of antipathy towards the enemy…”
“Blind xenophobic hatred,” the captain broke in. “I was afraid of that.”
“As I’ve said, friend Fletcher,” said Prilicla, “It is difficult to be precise, but my feeling is that they don’t hate us so much as what we are doing.”
“But we aren’t doing anything wrong,” the other protested, “at least that we know about. No matter, we have to stop them before they get any closer. Haslam, launch the chemical pyrotechnics. Spread them in front of their line at twenty-meter intervals. Dodds, use your tractor beam to pull off bunches of burning vegetation and drop them into any smoke-free gaps. I want our perimeter protected by a line of fire and smoke. Stand by to deploy the meteorite shield if that doesn’t work.”
Distress flares shot from Rhabwar’s launchers made low, fiery arcs in the sky before landing at the designated intervals among the trees.
“After three days’ heavy rain,” the captain added for Murchison’s benefit, “the vegetation is still too damp for there to be any danger of us starting a conflagration. We will be producing mostly light, steam, and smoke.”
The intense blue light and heat of the chemical flares, which had been designed to be seen across thousands of miles of space, caused the damp surrounding vegetation to fairly explode into flame. Dodds picked at the hottest spots with his tractor beam, moving clumps of burning branches into the intervening areas where the vegetation had been unaffected. A dense pall of steam and smoke rose into the sky so that the sun became a dark orange shape that wavered in and out of visibility. A few minutes later they could see through the dissipating smoke that the secondary fires were dying down, and those where the flares had landed were not looking too healthy, but they had done their work.
“A wind off the sea is blowing the smoke inland,” said the captain. “The spider force is withdrawing and heading back to their ships. So far as we can see, no injuries have been sustained.”
“Their emotional radiation confirms,” said Prilicla, “but they are badly frightened and their dislike of us has increased.”
“Sir,” Lieutenant Haslam reported before the captain could reply, “the ships on the other side of the island must have seen the smoke. A glider has been launched. It is slope-soaring over the high ground and heading this way, obviously to find out what has been happening. I think we won this one.”
“We won this battle, Lieutenant,” said the captain, “but not the war. If we win the war that means we lose, because the only way to win this war is to stop it before anyone gets hurt.
“I’m open to suggestions.”
CHAPTER 30
For the remainder of the day, between breaks for meals, checks on the patients, and a period of rest for himself, they watched the glider overhead because there was nothing else of interest happening. The spider aircraft was doing some very interesting things, like signaling to its mother ship on the other side of the island and the three vessels drawn up along the beach.
A large, circular panel close to one wing-root had opened and begun spinning in the slipstream about its two diametrically opposed attachment points. One face of the panel was bright yellow while the other matched the overall brownish-green color of the glider. The rotating disk was within easy reach of the pilot who used one of its forelimbs to check the spin at irregular intervals to show either the light or dark face to watchers below and on its more distant mother ship.
“Ingenious,” said the captain admiringly. “It’s using the visual equivalent of Earth’s old-time Morse code. The spiders might not have radio but they can communicate over short to medium distances. The rotating panel would have minimum effect on the glider’s flight characteristics, and any information being transmitted would be passed slowly, although if necessary the message could last for as long the glider remained aloft. Judging by the pauses in signaling, which last for anything up to
fifteen minutes, I’d say that there is a similar device on the mother ship and they are talking about us.”
“Sir,” said Haslam. “It’s not heading back to its ship. Why is it still climbing? I would have expected it to come down to take a closer look at us so that the pilot would have more to talk about.”
The captain exercised the prerogative of a senior officer who did not know the answer by maintaining a commanding silence.
The litters bearing all of the patients were moved into the afternoon sunshine of the beach although, as it had been in the recovery ward, the druul-like Earth-human casualties and those from the Trolanni searchsuit were separated from visual contact by portable screens. There were a few spiders moving about the beach, but they stayed close to their ships and it was plain that another attack was not imminent. To conserve power the meteorite shield had not been deployed so that the patients could benefit from the sea breeze as well as the sunshine. They, too, lay watching and talking about the slowly ascending glider. It was still climbing late in the afternoon when the patients were moved indoors and when the sun began to sink behind the high ground inland. When dusk fell at ground level it was still climbing, tiny with distance but clearly visible in the bright, orange light of the sun which for it had not yet gone down. It began circling widely and performing slow, intricate aerobatics.
