At the outset of World War One, many regarded New York's Seventh Infantry Regiment as a social club for Manhattan's most prominent sons rather than a serious National Guard unit. But on 29th September 1918 they proved their critics wrong. As part of the newly-formed NY 107th Infantry Regiment, they attacked the Germans' feared Hindenburg Line. At a frightful human cost, suffering more fatalities on a single day than any other regiment in American history, they broke the enemy line and helped to bring the war to an end. In this book, Great War expert Stephen Harris follows these "silk stocking soldiers" from the outbreak of war to their triumphant return home.
