The Cylinder Falls
The Narrator, a philosophical writer, sees a strange, green meteor fall onto Horsell Common near his home in Maybury, Surrey. Initially mistaken for a meteor, it soon reveals itself to be a large, cylindrical object. A crowd gathers, including Ogilvy, an astronomer, who dismisses the idea of life on Mars. The Narrator visits the site and sees the cylinder embedded in the sandy pit. He describes the growing public curiosity and the general excitement mixed with slight unease, as people from Woking and other nearby towns flock to witness the spectacle.
The Martians Emerge
The top of the cylinder unscrews, and a terrifying creature, a Martian, slowly emerges. The Narrator describes them as large, greyish, oily bodies, with V-shaped mouths and prominent eyes, lacking lungs or digestive systems. Three men, including Ogilvy, approach the pit with a white flag, trying to communicate. Suddenly, a blinding flash erupts, and a Heat-Ray incinerates them and the surrounding trees. The Narrator, witnessing this horror from a safe distance, realizes the danger and flees, narrowly escaping the initial destruction and the alien's aggression.
The Martian Offensive Begins
More cylinders land across the English countryside, and from them, the Martians build massive, three-legged 'fighting-machines' or tripods. These metallic giants, armed with the Heat-Ray and later, the Black Smoke, begin destroying towns and military forces. The Narrator, after a harrowing journey home and a brief reunion with his wife, understands the scale of the invasion. He sends his wife to safety in Leatherhead, believing she will be safer there, while he returns to his home in Maybury to observe the catastrophe, driven by curiosity and a sense of duty to document events.
Flight and the Curate
London falls into chaos as the Martians advance. The Narrator, after a desperate search for his wife, joins the mass exodus from the city. He encounters a terrified and increasingly deranged Curate, whom he takes under his protection. The Curate's religious fanaticism and constant pronouncements of divine judgment become a burden. They witness horrific scenes of destruction and human desperation, including the 'Fighting Machine' on the road to London, and the destruction of Weybridge. The Narrator struggles to maintain his sanity and pragmatism amidst the Curate's escalating hysteria and the widespread devastation.
Trapped in the Ruined House
While seeking shelter, the Narrator and the Curate become trapped in a ruined house in Sheen, after a Martian cylinder crashes nearby. They hide in the scullery for days, observing the Martians' activities through a crack in the wall. The Martians establish a base, constructing a huge gantry and other machinery, and begin to harvest human blood. The Curate's increasingly loud and irrational behavior puts them both in peril, as his cries threaten to expose their hiding place. The Narrator is forced to knock him unconscious to silence him, an act of self-preservation.
Escape and the Artilleryman
After the Curate's death – presumably from Martian detection or starvation – the Narrator escapes the ruined house. He wanders through a desolate, Martian-ravaged land, encountering an artilleryman. The artilleryman, initially appearing resourceful, outlines a plan to rebuild civilization underground, but his talk quickly becomes vague and impractical. The Narrator recognizes the man's delusion and, disheartened by his lack of true pragmatism, leaves him to continue his solitary journey through the devastated countryside, further cementing his sense of isolation.
Journey to London and the Red Weed
The Narrator makes his way back to London, finding the city eerily silent and deserted. The Martians have introduced a crimson alien vegetation, the 'Red Weed,' which spreads rapidly across the land, turning the Thames a bloody red. He sees the Martians' discarded fighting machines, now inert, and observes the widespread devastation. The silence of the city and the alien flora create a chilling atmosphere of post-apocalyptic desolation. He is struck by the complete absence of human life and the overwhelming dominance of the alien presence.
The Martians' Demise
To the Narrator's astonishment, he discovers that the Martians are dying. Their fighting machines are motionless, and the creatures themselves lie lifeless. The cause of their demise is not human resistance, but Earth's microscopic bacteria, to which the Martians, having no natural immunity, are vulnerable. This revelation highlights the planet's own defense mechanisms and the unpredictable nature of biological warfare. The Narrator reflects on the irony of humanity's helplessness against the invaders, only for a microscopic force to achieve what no weapon could.
Reunion and Aftermath
The Narrator, weakened and traumatized, makes his way to his cousin's house in Putney, where he is unexpectedly reunited with his wife, who had safely reached Leatherhead. Their reunion is emotional and filled with relief, but also tinged with the lingering trauma of their experiences. In the aftermath, humanity begins the slow process of rebuilding, but the world is changed. The invasion is a stark reminder of humanity's vulnerability and the potential for life beyond Earth. The Narrator contemplates the lessons learned and the shift in human perspective caused by the alien encounter.
The Brother's Account
Interspersed throughout the Narrator's account are chapters detailing the experiences of his younger brother in London. The brother witnesses the panic and chaos as the Martians approach the city, describing the mass evacuations and the breakdown of order. He joins a desperate throng attempting to escape by sea from the east coast. He describes the harrowing journey, the Martian attack on refugee ships, and his eventual escape to the continent, highlighting the widespread nature of the invasion and the desperate measures people took to survive. His perspective offers a broader view of the national catastrophe.
