A first-person narrator recounts a sudden invasion from Mars: cylindrical projectiles strike the countryside and disgorge towering tripod machines that devastate towns with a heat-ray and noxious gases. Panic spreads as civilians flee toward the metropolis, transport and order collapse, and isolated acts of courage and cruelty occur, including a naval attempt to halt the attackers. Survivors endure confinement, starvation, and moral testing while cities lie smothered in wreckage. The campaign ends unexpectedly when the invaders fall victim to terrestrial microbes. The account examines human vulnerability, scientific hubris, imperial assumptions, and both communal and individual responses under extreme crisis.
