Howe was doing what able officers with him, such as Cornwallis, Grey, and the German Knyphausen, appear to have been unanimous in thinking he should not do. He was misled not only by the desire to strike at the very center of the rebellion, but also by the assurance of the traitorous Lee that to take Philadelphia would be the effective signal to all the American Loyalists, the overwhelming majority of the people, as was believed, that sedition had failed. A tender parent, the King, was ready to have the colonies back in their former relation and to give them secure guarantees of future liberty. Any one who saw the fleet put out from New York Harbor must have been impressed with the might of Britain. No less than two hundred and twenty-nine ships set their sails and covered the sea for miles. When they had disappeared out of sight of the New Jersey shore their goal was still unknown. At sea they might turn in any direction. Washington's uncertainty was partly relieved on the 30th of July when the fleet appeared at the entrance of Delaware Bay, with Philadelphia some hundred miles away across the bay and up the Delaware River. After hovering about the Cape for a day the fleet again put to sea, and Washington, who had marched his army so as to be near Philadelphia, thought the whole movement a feint and knew not where the fleet would next appear. He was preparing to march to New York to menace General Clinton, who had there seven thousand men able to help Burgoyne when he heard good news. On the 22d of August he knew that Howe had really gone southward and was in Chesapeake Bay. Boston was now certainly safe. On the 25th of August, after three stormy weeks at sea, Howe arrived at Elkton, at the head of Chesapeake Bay, and there landed his army. It was Philadelphia fifty miles away that he intended to have. Washington wrote gleefully: "Now let all New England turn out and crush Burgoyne." Before the end of September he was writing that he was certain of complete disaster to Burgoyne.
