Short answers, pulled from the story.
Mikhail Kutuzov was born in Saint Petersburg on the 16th of September 1745. His father served for thirty years with the Corps of Engineers and his mother Anna Illarionovna Beklemisheva came from a family of high Russian nobility.
While charging at the town of Alushta, Mikhail Kutuzov was shot in the left temple by an almost certainly fatal wound that went right through his head and exited near the right eye. He slowly recovered though frequently overcome by sharp pains and dizziness while his right eye remained permanently twisted after the injury.
Mikhail Kutuzov lost power because Emperor Alexander believed waiting for reinforcements would be seen as cowardly and ordered troops off the strategic Pratzen Plateau despite Kutuzov's objections. When Kutuzov asked where Alexander planned to move troops he was told it was none of his business and Napoleon seized the ridge immediately.
Mikhail Kutuzov was appointed commander-in-chief on the 17th of August 1812 and joined the army on the 29th of August 1812 at Tsaryovo-Zaymishche. He decided to give a major battle on approaches to Moscow two weeks later when two huge armies clashed near Borodino on the 7th of September 1812.
Mikhail Kutuzov died on the 28th of April 1813 at Bunzlau in Silesia which is now Bolesławiec Poland. He is buried at Kazan Cathedral by sculptor Boris Orlovsky after falling ill early in 1813.
