"Don't be a pigheaded idiot!" roared Connel. "Nothing will happen to those men now, and in five minutes there'll be so much confusion around here that we'll be able to walk over and open the door without firing a shot!"
Suddenly there was an explosive roar behind them and they spun around. On the opposite side of the canyon three rocket ships were hurtling spaceward.
"They must have spotted our fleet coming in," said Connel, a puzzled frown on his face.
"But how could they?" asked Astro. "We knocked out their radar!"
Connel slammed his fist into the palm of his hand. "By the stars, Astro, we forgot about their monitoring spaceship above the tower! When we knocked out the main station here in the canyon, it took over and warned the base of the attack!"
From all sides the canyon reverberated with the roaring blasts of the Nationalist fleet blasting off. Around them, the green-clad rebels were running to their defense posts. Officers shouted frantic orders and workers dropped tools to pick up guns. The building that held Carson and the other planters was suddenly left alone as the guards hurried to ships and battle stations.
Connel counted the number of ships blasting off and smiled. "They don't stand a chance! They're sending up only two heavy cruisers, four destroyers, and about twenty scouts. The Solar Guard fleet will blast them into space dust."
Astro jumped up and started to run.
"Hey, Astro! Where are you going?" shouted Connel.
