Written by two dedicated local historians, The History of Camp Upton is a comprehensive account of the WWI training ground and WWII 1222nd Army Reception Center located in Yaphank, NY. Through their passion of unearthing local history, both authors illustrate its daily operations, how it changed throughout time, and with surprises of lesser known truths about the camp. Price includes shipping.
