It was thus clearly evident I could do nothing, although I now possessed a well defined theory of just what had occurred. To my mind Eric was in the hands of Fagin, either hidden securely away among the sand caves for some purpose connected with Grant's treachery, or else with the intention of claiming the reward for his capture offered by Howe. The former probably seemed most likely in view of Grant's failure to return to Philadelphia with Colonel Mortimer, yet there was no reason why the conspirators should not wreak vengeance, and win the reward also. But did Claire know, or suspect the predicament of her brother? If she did, then she was seeking to conceal the truth from her father, but would never remain long inactive in the city. I knew the girl's real spirit far too well to believe she would fail for long in learning the boy's fate. And when she did she would act quickly. Perhaps even now she was back at Elmhurst, facing peril in the track of the contending armies, striving to give the lad refuge. In an agony of apprehension I asked for a scouting detail in that direction, but was sternly refused. Word had come that Clinton was evacuating Philadelphia; that his advance was already across the Delaware. Any moment might bring to our little army orders to press forward to intercept him. I was a soldier, compelled to remain. CHAPTER XXVI FORCING CLINTON TO BATTLE I was left behind at Coryell's Ferry, for the purpose of hastening forward any supplementary orders from Washington, when Maxwell, and the Jersey militiamen, pressed forward in an effort to retard the march of the enemy. From the reports of scouts we began to understand what was occurring. Before dawn on the eighteenth of June the British army began leaving the city, crossing the Delaware at Gloucester Point, and by evening the motley host, comprising Regulars, Hessians, Loyalists, and a swarm of camp followers, were halted near Haddenfield, five miles southeast of Camden.
