According to most of my readings on the subject, AGC's infantry was in no condition and lacked the logistics for a final assault on Moscow in August of 1941. However, AGC's panzer devisions were possibly capable of penetrating the final 200 miles from Smolensk to Moscow during that time. So my question pertains to what Guderian (the main advocate for an earlier advance towards the Russian capital), planned to do once he reached Moscow while the bulk of his infantry slogged behind cleaning up the hundreds of thousands of Russian defenders that would probably have been pocketed by the panzer pincer movements. I believe it would have been at least several weeks before the infantry caught up to the tanks. So Guderian (a brilliant German general), had to know ahead of time that his tanks would arrive at the gates of Moscow well before his foot soldiers would (based on the previous pace of the Barbarossa advance), and I wonder if he had ever revealed any official plans for what he wanted to do once he got there. Was he planning to encircle and cut off the huge city while he waited for his storm troops to arrive, or was he planning to send the panzers directly into Moscow which could have invited disaster much like Stalingrad?
The historian David Stahel, author of "The Battle of Moscow", discusses this in this video lecture: https://www.youtube.com/watch?v=e4XEbJOqTCo. tl;dr: it would have been impossible for Guderian to do anything with tanks alone.
