The border had been reached.

The American army had not followed.

It was, in the most precise possible sense, the completion of the flight.

The flight that started with a peace party carrying a white flag in a canyon in Idaho in June 1877, that moved through a thousand miles of mountains and plains and rivers and the worst the northern autumn could offer, that ended in two places simultaneously: surrender at Bear Paw and escape to Canada.

Both of those places are where the flight ended.
