Historical territorial chronology consulted; no source artwork or prose republished The eastern campaign front does not extend Soviet control into Greece, Albania, or the Yugoslav Partisan theatre. For January 1945, liberated Greece and Albania use the closest published 1945 national reference. Bypassed island garrisons fall outside its regional precision.
The moving front follows the source-map position for 1945-01-15. The source date is kept separate from the chapter anchor; manual registration has the precision of a regional map.
The legacy Italian front ID is retained, while its geometry follows the actual dated front. In June 1944 the front is near Rome, rather than prematurely at the Gothic Line.
Slovak territory is reconstructed from the published 1938–1945 border-change map, which separates the client state from Hungarian and German annexations. This regional source does not resolve small northern frontier changes or survey-level detail. After August 1944, German military occupation supersedes the client-state fill.
Published prewar regional land geometry supplies a geographic reference for military control documented separately. Lastovo is Partisan-held after September 1943; Zara changes after October 1944. These regional fills do not claim continuous control of every rural locality.
The dates of published political outlines retain the resolution available in their sources. Military fronts and operational perimeters have their own source and method records.

Layer records and reconstruction methods
The moment in context The Ardennes offensive was meant to change the political situation as well as the military one. In December 1944 Hitler sent his forces west in the hope of splitting the British and American armies and taking Antwerp. If the blow produced a rupture among the Allies, Germany might escape defeat. Surprise helped the attack at first, but the distance to Antwerp required fuel, transport, and reserves Germany did not have. Within weeks the offensive had failed, and the forces spent on it were unavailable for the defense of Germany.
