Operation Barbarossa

Key Takeaways The gauge problem: Soviet railways used a 1,520mm gauge; European railways used 1,435mm. German trains couldn't run on Russian tracks without conversion. The conversion bottleneck: Converting track required enormous labor and materials. At peak efficiency, German engineers converted about 30 km of track per day—far slower than the army's advance. The supply gap: The gap between the advancing front and the end of converted rail created a "supply vacuum" that had to be filled by trucks, which consumed their own fuel and wore out on Russian roads. The cumulative failure: By the time the Wehrmacht reached Moscow's suburbs, its supply system was delivering only 10-20% of required tonnage. The army that arrived was too weak to take the city. The Lesson Not Learned On June 22, 1941—exactly 129 years after Napoleon’s Grande Armée crossed the Niemen River—Adolf Hitler launched Operation Barbarossa, the largest military operation in human history. More than 3 million German and Axis soldiers invaded the Soviet Union along a front stretching 1,800 miles. ...

The Invisible Army ← Series Home Key Takeaways Infrastructure is strategy: Russia's wider railroad gauge (1,520mm vs. Germany's 1,435mm) meant German trains couldn't use Russian tracks—forcing either gauge conversion or transshipment at the border. Conversion takes time armies don't have: German engineers could convert about 50km of track per day. The front advanced 50km per day in the first weeks. The railhead never caught up. Trucks can't compensate: Germany tried to bridge the gap with trucks, but vehicles consumed fuel faster than they could deliver it over Russian distances and roads. The tyranny of distance: At 500km from the border, the logistics math collapsed. The German army was literally starving as it approached Moscow. The Plan That Ignored Logistics Operation Barbarossa, launched on June 22, 1941, was the largest military operation in history. Three million German soldiers, organized into 150 divisions, invaded the Soviet Union along a 1,800-mile front. ...
