So let me get this straight, the Germans in WW1 with horses at best were able to advance through Russia at a rate higher then the average rate of advance of the Wehremacht during the first 3 weeks of Barborosa. And not just advance faster but almost twice as fast? The average Wehremacht advance was 28 km or 17 miles per day with tanks rolling.
Damn, now how is it that the Germans were not able to take Paris in WW1? Or why is it, it took them 3 years to take Poland? I'll let you mull that for a while.
Spoken like the DU and all political expidients.
They were fighting a Soviet army that hadn't quit yet. The Russian army in 1918 had quit. By the way the Wehrmacht was not all that mechanized in WW2. Most of the transport for the infantry was horses and wagons. The tanks had to wait for infantry support to come up. It's history, you should look it up.
