Have you ever seen a map of the Moscow region lately? Do you realise this reagion was particularly crisscrossed with watelines, and strewn with wooded and built-up areas? Where have you came up with this strange notion that "they had already partly closed a ring around"? Can you please show me a map with this precious information? Well, if they had to have help from the main manoeuvre force of the neighbouring Army Group this means they simply were not up to the task, they had the means for one arm of the pincer only, isn't it? All the Germans had to do? Can you please provide an estimate of how many troops you would need to reinforce Army Group Centre with to enable it to perform this manoeuvre? And how would you supply them and through which specific roads?
