I'm near the end of finally reading Guderian's 'Panzer Leader' he published in 1952. (Covid is good for something) The Barbarossa op was one of those cluster/gaggle things you hear so much about pretty much from the start in June of '41. Primarily caused by interference from the Germanicon General Staff. Hitler didn't start screwing things up until a bit later. I'd have to look to see where 8 Panzer Div was working. I think it was under Heinz who was boss of 2 Panzer Army in the Central Army Group.
Logistics was nearly non-existent and not just because of the rail road gauges. A lack of logistics combined with repeated changes in orders and objectives from the 'armchair', political, generals.
And then it all went down hill when the weather got wet in the Fall. Heinz talks of a sea of mud over the entire theatre. Nothing moved. Not even the bikers. There were no paved roads and no trucks anyway. Wheeled vehicles couldn't go anywhere and neither could tracked vehicles. Plus they were dealing with miles and miles and miles of distances. Supply depots were hundreds of miles behind the troops.
Oh and the "bikers" were the Panzer Div Recce guys.
