In daily streaks, what was the longest Emperor Napoleon wasn't in France?
1806-1807: I don't think Napoleon returned to France in the 4th coalition, but idk how long pre-war he left France and post-war returned to France. Conservatively, 9 months away?
1809: Napoleon left France in April. He returned post-Schonnbrun. Idk what day. Conservatively, 6 months away?
1812: Idk when Napoleon left France, but he returned in December - conservatively, 6 months?
1813: Napoleon fought at Lutzen in May, so he must've left France pre-May. He didn't return up to November. 6-7 months?
1814-1815: For fun, let's count Elba. He landed in Elba May 4, left February 26. +2 days travel to and from France, that's 300 days. Are any campaign absences longer?
I left out 1805, because I doubt he took longer to leave and come back. But it maybe surprisingly, if he took his time post-Austerlitz.
