The Eastern Front of the European Theatre of World War II encompassed the conflict in central and eastern Europe from June 22, 1941 to May 9, 1945. It was the largest theatre of war in history in terms of numbers of soldiers, equipment and casualties and was notorious for its unprecedented ferocity, destruction, and immense loss of life (see World War II casualties). The fighting involved millions of German, Hungarian, Romanian and Soviet troops along a broad front hundreds of kilometres long. It was by far the deadliest single theatre of World War II. Scholars now believe that at most 27 million Soviet citizens died during the war, including at least 8.7 million soldiers who fell in battle against Hitler's armies or died in POW camps. Millions of civilians died from starvation, exposure, atrocities, and massacres. The Axis lost over 5 million soldiers in the east as well as many thousands of civilians.
