“Reaching Louisville late on the afternoon of April 22, Grierson found the townspeople had boarded up their buildings in preparation of his arrival. Again, Grierson showed his concern for the welfare of Southern civilians by issuing strict orders; “drive out stragglers, preserve order, and quiet the fears of the people.” (CW) The Federal cavalrymen passed through Louisville without incident, only to strike a dismal swamp where they lost several horses from drowning. On April 23, they moved through Philadelphia, stopping to rest at 10 o’clock that evening.”
