It would be all guesswork. There are reports that when they had crossed the Buffalo they sat around for a while, segments left and came back. So one cant put a time to that. They also hrrassed some of the Fugitives, again a time span. And lastly there is no starting time for when the reserves were thrown into the action.
Considering the distance is around 12 miles approx 19kilometers, extremely rough terrain, add in the above issues then take a guess.
Sorry thats all I can contribute.
