A Strange First Attack

The Cloudlets Descend
An alien arrival
Green cloudlets gather over a mountain valley, then combine into a destructive mass. The Second Men encounter a living form that does not fit their assumptions about bodies or consciousness.
A first defense
Radiation beams disrupt the invader, which retreats to Mars. The encounter saves the valley but leaves both species unable to understand the other’s nature.
The Second Invasion

The Earth Is Stripped
Resource seizure
The Martians attack rivers, forests, and settlements, carrying water and plant matter back to Mars. Dense cloud-jellies flatten cities and kill inhabitants.
A hard-won victory
Humanity devises electrical weapons that destroy the invading clouds. Their remnants, however, spread a disease that severely damages the Second Men’s bodies and institutions.
Repeated Raids

A Recurrent War
Adaptation and counterattack
The Martians return with defenses against humanity’s latest weapons, and humans repeatedly devise new means of resistance. Each encounter renews devastation without resolving the fundamental misunderstanding.
Unequal recovery
Earth rebuilds slowly after each raid, while Mars gains water despite losing many inhabitants. The repeated pattern exhausts humanity and strengthens the Martian capacity to continue.
Colonies and Revolts

The Enemy Becomes Legible
A change in understanding
Living among terrestrial conditions, some Martians recognize that human beings are the planet’s actual minds. Their inherited public ideology begins to lose its hold on private thought.
A recurring suppression
The Earth colony repeatedly begins a spiritual transformation, only to be destroyed by orthodox forces from Mars. Human settlements rebuild behind electrical barriers amid intermittent attacks.
Double Extinction

A War Without Survival
Total commitment
Humanity’s disorder turns a proposed deadly weapon into an unexamined policy. A bacterium is released that destroys the Martian colonies and infects Mars itself.
The human aftermath
The human population also succumbs to disease and grief, abandoning the work of rescue. A small remnant survives, but the Second Men enter a prolonged racial sleep.
