How long was the front line of Operation Barbarossa?

The invasion of the Soviet Union, known as Operation Barbarossa, was launched along a front line of 1,800 miles (2,900 km).1

This vast theater of combat, which stretched across eastern Europe from the Baltic Sea in the north to the Black Sea in the south, spanned approximately 800 miles (roughly 1,300 km) in a direct line, though the distance was more than twice that when measured along the borders between the opposing countries.2
