People had fled the cities in a mass exodus to escape the terror of the merciless Martians. They didn't know at the time that they would not be any safer in the country or in wooded areas. The giant insects sought the hills and farm areas for food. Crossing grassy areas, the creatures often unwittingly crushed fleeing humans under their huge legs. There wasn’t an obstacle that could stop the monsters. Homes were smashed to bits if they lay in the path of the on-rushing beasts. The inhabitants’ only warning of peril was the crash of heavy foot-steps as the creatures approached. Their only hope for survival was to hide before the insects detected them.
