The moving front follows the source-map position for 1941-12-06. The source date is kept separate from the chapter anchor; manual registration has the precision of a regional map.
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.
The eastern Italian frontier uses the published 1930s regional map and a reconstruction of the 1924 Fiume boundary. Source conquests after April 1941 remain separately dated.
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.

The moment in context Germany attacked the Soviet Union on the assumption that a series of victories near the frontier would destroy the state behind the armies. About 3.6 million Axis troops crossed the border in the largest invasion in history. Three army groups drove toward Leningrad, Moscow and Ukraine. At Minsk, Smolensk and Kiev, German mobile formations surrounded enormous Soviet forces; by winter more than three million prisoners had been taken.
