This special re-print edition of the United States War Department's book "Signal Pieon Manual" provides information on the use of Homing Pigeons as messengers during the Second World War. Written in 1944, this manual was issued to members of the U.S. Signal Pigeon Corps. The United States Army Pigeon Service (a.k.a. Signal Pigeon Corps) was a unit of the United States Army during World War I and World War II. Their assignment was the training and usage of homing pigeons for communication and reconnaissance purposes. During World War II, the force consisted of 3,150 soldiers and 54,000 war pigeons, which were considered an undetectable method of communication. Over 90% of US Army messages sent by pigeons were received. This reprinted text is fascimile of the manual issued during the last years of World War Two to enlisted men in the Signal Pigeon Corps on how to care for and utilize homing pigeons as millitary messengers. A fascinating read. Note: This edition is a perfect facsimile of the original edition and is not set in a modern typeface.
