"Call the defense forces," Bors commanded the grid office, by transmitter. "They'll be Mekinese--Mekinese-officered, anyhow. We don't want them to get ideas of attacking us, so identify us as the pirate ship _Isis_ and order all police and garrison troops to stay exactly where they are. Say we've got all our fusion-bombs armed to go off in case of an artillery-fire hit." This was the most valid of all possible threats against the most probable form of attack. Fusion-bombs could be used against enemies in space, or for the annihilation of a population, but they could not be used in police operations against a subject people. To coerce people one must avoid destroying them. So while a ship the size of the _Isis_ could--and did--carry enough confined hellfire in its missile warheads to destroy an area hundreds of miles across, the occupation troops of Mekin could not use such weapons. They needed blast-rifles for minor threats and artillery for selective destruction. In any case no sane man would try to destroy the _Isis_ aground after an announcement that its bombs were armed, and that they were fused to explode. "Now repeat the demand for stores," ordered Bors. "We might as well stock up. Speed is essential. We can't use stores they've time to booby-trap or poison. Give them twenty minutes to start the stuff arriving. Demand fuel, extra rocket-fuel especially. Remind them about our bombs." He waited. Speakers beside him could inform him of any action anywhere outside or inside the ship. The landing-party in the spaceport building reported as it went through the spaceport records, picking up such information concerning Mekinese commercial regulations, identification-calls and anticipated ship-movements as might prove useful elsewhere. The rasping voice began to broadcast again. It went on for fifteen seconds and cut off. "Tell the government broadcasting system that if they stop relaying our broadcast," said Bors, "we'll heave a bomb into the police barracks and the supply-depots." He heard the threat issued and very soon thereafter an agitated voice announced to the people of Tralee that a pirate ship was in possession of the planet's spaceport and that it insisted upon broadcasting to the planet's people. It was considered unwise to refuse. Therefore the broadcast would continue, but of course citizens could turn off their sets.
