By attacking the food supply of the world, the Martians hoped that they would be able to bring the Earth to its knees. The leaders of the invasion ordered the saucers to destroy all of the animals and farm land that existed. Sweeping over the nations of the world, the saucers destroyed acre after acre of wheat land. Animals were burnt to death by the searing heat rays that the Martians fired. Farmers stood by watching helplessly as cows, horses and chickens were destroyed. Trying to save as much of the livestock as possible, farmers hid the animals in shelters and barns. Some of the animals were kept in the family's own living quarters to keep them safe from the attacks.
