The British, in 1776 having failed to reach Philadelphia by the northward way through New Jersey, planned the 1777 campaigns to end with the capture from the southward by the Chesapeake of the capital of "the rebels." This was in accordance with the plan, as we now know, of General Charles Lee, second in command to Washington, while he was a prisoner in New York. He thus proved himself a traitor more despicable even than Arnold. His infamy did not become known until of late years. Moving northward from the head of the Chesapeake Bay, the British encountered Washington at Brandywine and, defeating him, secured an entrance to Philadelphia when it pleased General Howe to enter, which he did on September 26th, amid the welcoming acclaim of the people who remained. The Patriots had generally left the city. On the 23d the Navy Board ordered all vessels south of Market Street to move down the river and all north to go up the Delaware to escape falling into the hands of the British. Barry's "Effingham" went down the river. Barry, as the Senior Commander of the Navy at the Port of Philadelphia, had charge of the "row gallies, batteries" and other vessels protecting and maintaining the _chevaux de frize_ off Billingsport by sinking obstructions to prevent the passage to the city of any British vessels and thus effectually stopping the channel. The British erected a battery near the mouth of the Schuylkill upon which Barry's galleys fired at times but seemingly with but little effect, though "playing their part most nobly and acting like men and freemen convincing the world their liberty was merited," to use the words of Thomas McKean to General Rodney. When, on October 22, 1777, Count Donop attacked the Americans in Fort Mercer at Red Bank, the British fleet cooperated with the land forces, while the Continental vessels under Barry and the Pennsylvania fleet under Hazlewood drove them back, preventing their passage up the river. The British frigate the "Augusta" and the "Merlin" were driven ashore. The "Merlin" was set on fire by its crew. The powder on the "Augusta" exploded and that vessel was blown up. Portions of its remains are in the water off Red Bank to this day.
