On December 16, three German armies (more than a quarter-million troops) launched the deadliest and most desperate battle of the war in the west in the poorly roaded, rugged, heavily forested Ardennes. Despite Germany's historical penchant for mounting counteroffensives when things looked darkest, the Allies' leadership miscalculated and left the Ardennes lightly defended by only two inexperienced and two battered American divisions.

Its objective was to split the Allied armies by means of a surprise blitzkrieg thrust through the Ardennes to Antwerp, marking a repeat of what the Germans had done three times previously-in September 1870, August 1914, and May 1940. In December 1944, in an all-out gamble to compel the Allies to sue for peace, Adolf Hitler ordered the only major German counteroffensive of the war in northwest Europe.
