"The Chinese People's Liberation Army" is an English monograph written by American military historian Samuel Griffiths on the study of the course of development and growth of the Chinese People's Liberation Army (PLA). In his book, Griffiths made an in-depth study on the glorious history of the Long March of the Chinese Workers' and Peasants' Red Army through comparative study of the war histories of the East and the West. He said, "the repeated severe trials the Chinese Communists had gone through proves that they can certainly reach their goals since they could bear with indescribable hardships, take on all severe challenges the nature placed along their way in a seemingly resolve to stop their advance, and defeat the enemies who were determined to destroy them."

　　Samuel Griffiths is among the first experts in the foreign military field to study Mao Zedong's military thinking and publish the related academic works. In his book "The Chinese People's Liberation Army", he spoke highly of the great Long March, and stressed that in the 4th century BC, after his expedition to Persia, Alexander led 10,000 Macedonian troops in a great retreat. His troops spent four months to cover 3,200km, during which they had to fight many battles, climb snow-capped mountains and cross swamplands. Compared with the Greeks' retreat from Persia to the Black Sea in 400 BC, the Long March of the Red Army is " a feat of greater daring ". The Long March of the Red Army is unparallel in the world in terms of its scale, its untold difficulties and its heroic achievements, etc.
