The Battle of Korad

The Battle of Korad is a green Martian ambush of a peaceful Helium scientific expedition, in which twenty airships are met by a sudden, disciplined volley and driven into retreat. Its immediate result is the capture of Dejah Thoris, whose presence transforms the battle from a remote clash into the central personal encounter of John Carter’s early life on Mars. The episode also binds warfare to the planet’s precarious infrastructure: the expedition had been surveying atmospheric conditions, and the survival of all Martian peoples depended on the scientific work its attackers interrupted.

Background and Sudden Attack

Three days after an incubator ceremony, Lorquas Ptomel’s traveling community set out toward home. The procession had barely emerged into open ground when orders sent it hastily back. Green Martian warriors vanished into the doorways of nearby buildings in less than three minutes, an abrupt dispersal that revealed how quickly the caravan could turn itself into a concealed force.

John Carter and Sola were inside a building at the city’s front. Carter climbed to an upper floor to learn what had caused the retreat and saw a long line of gray airships coming slowly over the nearest hill. One ship followed another until twenty were sailing low above the ground. The scale and deliberate approach of the fleet initially gave no clear indication that its crews had detected the hidden warriors or understood that the city was occupied.

The expedition was not on a military mission. Dejah Thoris later explained that her party had been sent by her grandfather, the Jeddak of Helium, to rechart air currents and take atmospheric-density measurements. Its banners and the colors of its craft marked it as a peaceful research party, not a force advancing to attack. The mismatch between the expedition’s purpose and the reception it received is the battle’s decisive irony: the green warriors fired before the approaching ships could establish their intentions.

The Exchange of Fire

The green Martians opened fire without warning from windows facing the valley. The foremost airship swung broadside and returned the attack with its guns, moving parallel to the green Martian position before turning in a wide circle to bring itself around opposite the firing line. The ships behind it followed the same maneuver, opening fire as each reached position.

The defenders’ volley was strikingly accurate. Carter observed that the shots seemed to bring down figures aboard the ships while banners and upper works broke apart in bursts of flame. The green warriors’ fire did not slacken, and their coordinated targeting made the opening ambush more than a single burst of violence. Their marksmen had prepared to disable an attacking fleet by concentrating on its weapons and personnel; the later account of green Martian combat practice describes specialists assigned to the guns’ wireless-finding and sighting apparatus, smaller guns, gunners, officers, crew, steering gear, and propellers. The battle shows the practical effect of this division of fire: a fleet caught unprepared could lose its ability to fight and maneuver before it could organize a response.

The shipboard guns proved ineffective against the first volley. The crews had been caught unprepared, and the guns’ sighting apparatus was left exposed to the defenders’ aim. After twenty minutes, the fleet turned away. Several ships were visibly damaged and barely under the control of their depleted crews; their fire stopped as they concentrated on escape. The warriors climbed to the roofs and continued shooting at the retreating ships.

One by one, the vessels disappeared below the distant hills. The last, already moving slowly and apparently without a visible crew, failed to escape with the others. It turned erratically back toward the city. Once the warriors recognized that it was helpless and unable to harm them, they stopped firing. The change from attack to restraint came not from mercy toward a fighting opponent but from the ship’s evident incapacity to resist.

Capture of the Damaged Ship

The returning craft drifted about fifty feet above the ground, its dead crew visible on the decks. The green Martians ran out onto the plain but could not reach the vessel while it remained aloft. Warriors moved ahead to the building it seemed likely to strike, then swarmed onto it through the windows just before impact. Using their great spears to ease the collision, they reduced the force of the crash; others threw grappling hooks and hauled the craft down.

Once it was secured, the warriors searched it from stem to stern. Carter saw them examine the dead sailors for signs of life, then watched a group emerge from below dragging a small, living prisoner. The captive was less than half the height of the green warriors and walked upright on two legs. From his distant vantage point Carter did not yet know who she was; he could only mistake her for another unfamiliar Martian creature.

The victors systematically stripped the ship over several hours. They carried away arms, ammunition, silks, furs, jewels, carved stone vessels, and solid food and drink, including casks of water—the first water Carter had seen since arriving on Mars. The wreck was not simply a battlefield prize: its contents offered the community useful supplies, while its sole surviving passenger would alter Carter’s understanding of the world around him.

Dejah Thoris and the Battle’s Personal Consequence

After the last load had been removed, the warriors towed the craft out into the valley. Carter later saw activity aboard it that appeared to involve emptying the contents of containers over the dead sailors and the vessel. Meanwhile, the caravan remained in the deserted city. Lorquas Ptomel considered it too dangerous to take chariots and children onto the open plains while the airships’ return remained possible; the homeward march was delayed for more than a week.

When Carter and Sola entered the plaza, he saw the prisoner being dragged into a nearby building by two green Martian females. His response was an unresolved mixture of hope, fear, exultation, and depression, with relief and happiness most prominent. The captive was slender and girlish in appearance, with features Carter associated with women on Earth, reddish-copper skin, and coal-black hair. She wore no clothing apart from elaborate ornaments. At first she did not see him; as she was taken through the doorway, their eyes met.

The woman made a small sign with her free hand. Carter did not understand it and did not answer. Her expression, which had brightened with hope and renewed courage when she noticed him, changed to dejection, contempt, and loathing as she was dragged out of sight. He realized only afterward that she had appealed to him for help and protection, and that his ignorance of Martian customs had prevented him from responding. The battle’s capture thus begins not with a rescue but with a failure of recognition: the future connection between the two is first marked by a plea Carter cannot read.

The prisoner identified herself as Dejah Thoris, daughter of Mors Kajak of Helium. She said the expedition’s scientific measurements were intended to rechart air currents and assess atmospheric density. Its work, she insisted, served the interests of the green Martians as well as those of Helium, because without the results of such operations there would not be enough air or water on Mars to sustain life. She described centuries of effort to maintain the supply despite interference from the green people. Her testimony recasts the attack as more than a military encounter: it has endangered a mission concerned with the shared conditions of planetary survival.

Political and Narrative Significance

Dejah Thoris addressed Lorquas Ptomel and the assembled warriors after describing the expedition’s purpose. She condemned the green Martians’ communal order as one that had left them without written language, art, homes, or love, and urged them to abandon hostility and join the red Martians in trying to regenerate a dying planet. The appeal did not immediately end the conflict. The warriors listened in silence, and Carter believed they had been moved; Tars Tarkas rose with an expression of inward struggle against custom and inherited ways, but the scene leaves the outcome of that moment open rather than presenting the battle itself as a reconciliation.

The episode places a concrete scientific purpose at the center of an action scene. The expedition’s measurements concern atmospheric density, while the later explanation of Mars’s life-support system identifies an engineered process for producing its air. The atmosphere plant separates the ninth ray from sunlight, stores it in reservoirs, combines it with refined electrical vibrations, and pumps the product to the planet’s principal air centers, where contact with the ether turns it into atmosphere. A later crisis makes clear that this system is vulnerable: when the keeper fails to report and the machinery stops, air pressure begins to fall across Mars. In that broader context, the Helium expedition’s work is not incidental exploration; it belongs to the technical effort by which the planet’s inhabitants maintain breathable air and water.

The battle also introduces a recurring tension between technical sophistication and social violence. The airships, their guns, and the green warriors’ disciplined targeting reveal formidable military knowledge, yet that capacity is directed first against a research party whose stated mission includes preserving resources shared by both peoples. Dejah Thoris’s plea gives the clash an explicit alternative to endless hostility: cooperation across the division between red and green Martians. The battle does not settle that political question, but it makes it personal for Carter. A prisoner glimpsed too late to answer his appeal becomes the living consequence of the ambush, while her account exposes the common planetary stakes beneath the two sides’ immediate enmity.
