THE MARCH TO THE FRONTIER
THE eastern ridge of the Appalachian chain runs like a mighty mountain wall southwest to northeast. From the Schuylkill to the Delaware there is only one pass in this barrier, the narrow gap through which rush the waters of the Lehigh. Bishop Spangenberg, whose military instinct was so sure that he might have risen high in the profession of arms, was prompt to realize the advantages entailed in the possession of this important pass, and emphasized them to Richard Peters.
I have considered that if Gnädenhutten is emptied and left to the enemy it may prove the ruin not only of all the settlements lying along the Lehigh and Delaware, but also of Philadelphia. If the French once come and build there a fort, it will cost as much, if I am not mistaken, as the taking of Crown Point to get it out of their hands. For if they put a garrison in the Gaps of the mountains, you you cannot come at them at all with any great guns.1
