16h 56min, aug 26, 1914 y - Battle of Tannenberg
The Russian army marched into Prussia. However, because of the differences in railway gauge between Russia and Prussia it was difficult for the Russians to get supplies through to their men. The Germans, on the other hand, used their railway system to surround the Russian Second army at Tannenberg before it’s commander could realise what was happening. The Russians lost the battle with thousands of men killed and 125,000 taken prisoner. Although the Germans won the battle, 13,000 men were killed.
