The Western Front was a front of the Red Army, one of the Red Army Fronts during World War II. The Western Front was created on 22 June 1941 from the Western Special Military District (which before July 1940 was known as Belorussian Special Military District). The first Front Commander was Dmitry Pavlov (continuing from his position as District Commander since June 1940). The western boundary of the Front in June 1941 was long, from the southern border of Lithuania to the Pripyat River and the town of Włodawa. It connected with the adjacent North-Western Front, which extended from the Lithuanian border to the Baltic Sea, and the Southwestern Front in Ukraine.
