Band of Brothers: E Company, 506th Regiment, 101st Airborne from Normandy to Hitler's Eagle's Nest is the late historian Stephen Ambrose's 1993 story of the titular U.S. Army unit's brutal journey from the beaches of northern France on D-Day to the surrender of Nazi Germany. Ambrose, the prolific author of a number of popular books detailing the histories of various military units and campaigns of World War II, as well as his well-received history of the journeys of Lewis and Clark (Undaunted Courage: Meriweather Lewis, Thomas Jefferson and the Opening of the American West) devotes his entire volume to one company -- a company that played a major if previously underappreciated role in the U.S. Army's march across Europe. While Ambrose's narrative tracks the unit's history, it also provides portraits of E Company's (known also as "Easy Company) officers and soldiers. These depictions of the individuals not only serve to remind readers of the individual sacrifices made by so many, but also serves to provide a glimpse into the role personal conflicts have in the functioning of a closely-knit military unit. Band of Brothers was adapted by film-maker Steven Spielberg and actor Tom Hanks for a miniseries that was broadcast initially in 2001 on the cable television network HBO.
