Maps have been integral to military conflicts and warfare since time immemorial, and many of these documents are highly prized by collectors and military historians. The American Memory Project at the Library of Congress recently created this fine digital collection of World War II situation maps from the years 1944 and 1945. Beginning with the D-Day Invasion, the maps provide information about troop positions throughout Western Europe, along with important graphical representations of various landmarks within the military landscape. Visitors can browse through the collection by title, creator, subject, place, or date. Perhaps the finest part of the site is an interactive essay that takes users through the Battle of the Bulge with a series of maps and some brief commentaries.
