Does writer Stephen Ambrose admire Meriwether Lewis in Undaunted Courage?
I think Ambrose admires both Lewis and Clark. You can see when he writes about some of the challenges they faced, how these two men and their party were utterly alone in the unmapped wilderness, and simply the personal presence and strength of Lewis to overcome obstacles and lead a party of such men won his admiration.
I thought Ambrose specifically liked the fact that the Corps of Discovery could do what they did on the expedition with both limited resources and limited technology. Lewis was a particularly able leader given the circumstances.
