1. The reference is not correct. Pages are useless and ch.1 of part 3 tells nothing about the campaign of 1807. At least because it describes november 1805.
2. I can't recall any trouble between Bagration and Kutuzov in 1812.
3. In many armies subordinates tried not to follow orders they didn't like. Specially when it was a matter of command. To name a few - Jerome Bonaparte declined to obey his brother's order to become subordinate to Davout and left the army. Murat declined to take command of the army after Napoleons leave and left shortly after him. Leaving the army to Eugene.
4. There was another tradition in Russian army. When commander higher in rank (or with seniority within the same rank) came with reinforcements he voluntary subordinated himself to the one who was already in fight. Examples are Miloradovich who subordinated Bagration in 1799 at Lecco and Bagration who subordinated Barclay. There were numerous examples in 1808-09 in Finland and in 1812-1814. It will take time to find them though. When needed references are so difficult to find[:I]
5. There is a map date 1847 here http://www.davidrumsey.com/maps1239.html
