WHEN Lincoln's assassin had been swallowed up in the darkness of the night and the clatter of his horse's hoofs had died away, it seemed at first thought a hopeless task to divine his probable direction or to organize anything but a haphazard pursuit. On second consideration, however, the choice of possible routes of escape narrowed down perceptibly. Booth, who had been seen on the stage by thousands, could not risk passing through northern cities where he might have been recognized by any chance passer-by. The country west of Washington was held by Federal troops; even if Booth was ignorant that the War Department had alarmed such far-away posts as Cumberland and Charlestown, he would have shied at the prospect of traversing these districts. Nor did the northwestern roads lead to friendly territory. There remained Baltimore, a town in which Southern sentiment always ran high and where Booth had many friends; and finally, the South itself, where the assassin could hope for acclaim and assistance.
