Papuan Campaign: the Buna-Sanananda Operation is the second of a series called AMERICAN FORCES IN ACTION. The series was prepared at the suggestion of General of the Army George C. Marshall, Chief of Staff. His foreword, as used in the original edition, appears on the previous page. The series was originally designed for military personnel only and primarily for wounded soldiers in hospitals to tell them the military story of the campaigns and battles in which they served. With the cessation of hostilities, Papuan Campaign is released as a public document. ………. This study was based on the best military records available. Although in its published form it contains no documentation, the original manuscript, fully documented, is on file in the War Department. Aerial photographs are by the Allied Air Forces, S. W. P. A.; all others are by the U. S. Army Signal Corps.
