More than 8,000 men served in the Fifth Marine Regiment during World War I and the occupation of Germany. Marine units were among the first to arrive in war-torn Europe in 1917, and they sustained greater casualties than other American units. This book tells the story of the "Devil Dogs" in World War I and the years after through the recollections of veterans recorded over the past century. The influenza epidemic that raged during the war is discussed. An annotated roster of the regiment lists each Marine, with service details provided where known.
