Welcome to the fourth and last part of our program, "A Princess of Mars." The story is from a series of books by Edgar Rice Burroughs. Last week, we told how John Carter observed a fierce battle between the green Martians and a race of red, human-like creatures. He also saw the beautiful Princess Dejah Thoris being captured after the battle. A short time later, John Carter, the Princess and their friend, the green Martian woman Sola, attempt to escape rather than face death. The Princess and Sola must flee while John Carter tries to slow the green warriors who are chasing them. John Carter continues to tell what happens in Edgar Rice Burroughs' story, "A Princess of Mars." The huge green warrior Tars Tarkas came slowly toward me with his thin sword. I backed away. I did not want to fight him. I did not wish his death. He had been as kind to me as a green Martian can be. As I stood watching him, a rifle fired in the distance, then another and another. Tars Tarkas and his warriors were under attack from another tribe of green warriors. Within seconds, a terrible battle raged. As I watched, three of the attackers fell on Tars Tarkas. He killed one and was fighting with the other two when he slipped and fell. I ran to his aid, swinging my sword. He was on his feet. Shoulder-to-shoulder, we fought against the attackers. They finally withdrew after an hour of fierce fighting.
