The questions most frequently addressed by historians in their study of American foreign policy during World War 1 normally concern either why the United States entered the war or why she ultimately rejected the postwar settlement, These questions lead scholars primarily to the study of neutrality from August 1914 to April 1917 and to an examination of peacemaking from November 1918 to March 1920. Unfortunately, the period of actual combat has, until recently, been all but neglected.
