points equidistant around Mars' equator. At each point a post like Weathering's own was established, with dirtworks in a square around it and atom-blast batteries mounted. Jimmy Crane, who had shown aptitude thus far in Martian campaigning, was made commander of one of these posts and a Lieutenant Lanson commander of the other. Halkett and Burnham stayed in Weathering's own post.
Eighty of the ninety-seven rockets that had landed safely. Weathering now sent back to earth for more men and supplies. Word came from earth that fifty new rockets had been constructed and were on their way with men and materials. Weathering distributed them equally among his three posts when they came and sent them also back to earth for more. Crane and Lanson, under his orders, had devastated the oases around their posts to drive the Martians back from them.
Chapter 2
The Conquest Of Mars
Weathering's men were becoming acclimated to Martian conditions. The oxygenation treatments eliminated most of the Martian fever, and as the earthmen's muscles attuned themselves gradually to the new gravitation their movements became more sure. It is worthy of note that some of those first venturers who went back from Mars to earth after a year on the red planet were stricken by a sort of earth-sickness due to earth's different conditions.
As reinforcements came in. Weathering continued to distribute them among the three posts of Crane and Lanson and himself. He wanted to establish the three forts firmly before an overwhelming Martian attack swept them out of existence. There were signs that that could be expected from the Martians.
The Martian attacks were growing fiercer. The Martians could see plainly enough the course Weathering was following, and that each week brought more rockets from earth with more men, more supplies and more atom- blasts and atomic bombs. They determined upon a concerted attack to wipe out the earthmen's three forts before they became too strong.
The attack broke against the three forts, so widely separated, at the same time. It did not catch Weathering and Crane and Lanson by surprise — their atom-blasts were ready. But even so, the Martian attack was almost irresistible in sheer weight. From far across the reddish desert surged the furry Martian masses toward the three little forts, coming on despite the atom-blasts that took toll of them by tens of thousands.
Weathering's post and that of Crane withstood the attack by only the utmost endeavor. Halkett had charge of one of the atom-blast batteries at Weathering's fort, on the side that the Martians attacked most determinedly. It was Halkett's battery that wrought the deadliest destruction amid the furry hordes.
The third post, that of Lanson, fell. The Martians got inside with their chemical weapons despite the atom- blasts and bombs of the earthmen. Lanson and his garrison were massacred to the last man by the Martians. Only one of the three rockets stationed at Lanson's post escaped, a little before the fort fell, and got to Weathering with the news.
Weathering acted at once, despite his own precarious situation. He assembled sixteen rockets from his fort and Crane's, loaded them with men and weapons, and sent them under the command of Mart Halkett to reestablish the third fort. They did so, taking the Martians there by surprise, and managed to hold the place in the face of the Martian attacks that followed.
There followed a lull in the fighting, with Weathering, Crane and Halkett holding grimly on in the three forts. The Martians had lost tremendous numbers without dislodging the earthmen, and were in no mood for further attacks in force. Yet they did not retire but continued to encircle the forts.
But steadily the earthmen's strength grew as more rockets came in. Earth was aflame over the situation, cheering Weathering as the upholder of terrestrial honor. The gallant fight of earth's lonely outposts there amid the Martian hordes had appealed to the popular imagination and there were insistent demands that the Interplanetary Council use all its powers to reinforce them.
It meant to do so. It sent Weathering a message stating as much, advancing him from colonel to general, promoting Jimmy Crane to colonel, and Halkett and Bumham and a number of others to captaincies. The enlistment bureaus of the Council on earth could not handle the flood of recruits.
Rockets were now pouring from the factories in a steadily increasing stream. Atomic weapons were also being produced in quantity and every few days saw rockets laden with supplies and men taking off for Mars. Many perished still in the dangers of the void but most arrived safely. Weathering continued to distribute the men and supplies they brought among his three posts.
When the three forts were strong enough to be impregnable to any Martian attack. Weathering began the establishment of new posts. He proceeded methodically to dot Mars with small but strong forts, each covering a certain portion of the planet's surface. Hall Bumham was made commander of one of the first of these. Crane and Halkett retaining command of their posts.
Within a year Weathering had a network of fifty forts stretched over Mars' surface from the north polar snow-cap to the southern one. He had in them strong garrisons of bronzed earthmen thoroughly acclimated to the Martian gravitation and atmosphere, and well seasoned in fighting with the stilt-limbed Martians. By then Halkett and Bumham were commanding two of the fifty forts, while Jimmy Crane was now Weathering's second in command. The two worked together distributing, according to their plan, among the fifty. posts, the streams of men and materials arriving from earth.
With the next melting of the polar snow-caps. Weathering was ready to begin the final subjugation of Mars. From a circle of six of his forts he sent out strong forces to attack and drive together the Martians in that circular territory. This was the plan evolved by Weathering and Crane, to concentrate forces upon one section of the planet at a time, using the forts around that section as bases, mopping up the Martians in that section thoroughly and then proceeding to another.
Crane had charge of the first operation and it worked perfectly. The Interplanetary Council had directed Weathering to offer the Martians peace if they promised to obey the Government's authority. But Crane's men had no chance even to make the offer, so utterly fierce was the Martian resistance.
The Martians had never expected what happened. The furry, stilt-limbed men had ceased their attacks on the earthmen's forts some time before, save for occasional raids, and had retired to take up existence in the vegetation oases remoter from the forts. There they had lived as they had for ages, moving in nomadic fashion through the oases gathering the fruits upon which they subsisted, digging as ages of experience had made them skillful in doing for the underground springs. Now the earthmen were attacking them! The Martians rose madly to the fight.
But Crane's forces were strongly armed and with atom-blasts and atom bombs against their crude weapons the Martians had no chance. Those in that section were mostly killed in the fighting and the few remaining were herded into prison camps. Crane went on under Weathering's order to another section and repeated the maneuver. Halkett's fort was one of the posts around that section, but Halkett and Crane had small opportunity of seeing each other in the midst of the grim business of rounding up the Martians. With that section subdued like the first, the forces of Crane concentrated on another.
Within another year Weathering could send word back to the Council that the plan had succeeded and that except for a few remote wastes near the snow-caps, Mars was entirely subjugated. In that year approximately three-fourths of the Martian race had perished, for in almost every case their forces had resisted to the last. Those who remained could constitute no danger to the earthmen's system of forts. The Council flashed Weathering congratulations and gave Crane command of the expedition then fitting out on earth for the exploration of Jupiter.
Crane went back to earth to take charge of it, first taking warm leave of Mart Halkett and Hall Bumham at the posts they commanded. Crane spent a half year on earth preparing his expedition of two hundred rockets to meet conditions on Jupiter. For Jupiter presented a greater problem to earth explorers than had Mars, and biologists and chemists had been working to overcome the obstacles.
The greatest difficulty, Crane saw, was Jupiter's gravitation, almost twice that of earth despite the swift- spinning planet's counteracting centrifugal force. Gillen's visit to Jupiter on his epochal flight had been terminated by sickness brought on by that greater gravitation and the heavy damp atmosphere. Crane's men must be
