"An odyssey unequaled in modern times": Edgar Snow on Long March

In the summer of 1936, an American journalist crossed military blockades and entered a region almost completely closed to the outside world. There, he met the leaders of the Chinese Red Army and listened to the stories of those who had completed the Long March.
His name was Edgar Snow.
His book, Red Star Over China, gave the world a comprehensive account of the "odyssey unequaled in modern times."
