Merriam Press World War II History No. 20. First eBook Edition, 2015. This is a brand new edition of “Study No. 23: The Army Ground Forces: Training for Mountain and Winter Warfare,” originally published in 1946. This general study of the experiments in mountain and winter warfare training from 1940 to 1944 was designed as an introduction to the histories of the Mountain Training Center and the 10th Mountain Division. Its purpose was to trace the development of mountain and winter warfare training from its inception in 1940 to its termination in 1944. Considerable controversy attended the decisions of the War Department concerning mountain and winter warfare. This study was confined to an account of the actual decisions and the reasons for which they were made. This is an entirely new edition, with the addition of numerous photographs. 53 photos, footnotes.
