the combined Pennsylvania and Continental fleet was successful, repulsing one attempt by the British to pass the defenses of Forts Mercer and Mifflin on October 22 and 23, 1777 with the destruction of two British war ships, HMS Augusta and HMS Merlin, under the command of Admiral Francis Reynolds. The fleet also bombarded von Donop's forces as they attacked Fort Mercer, in the Battle of Red Bank, in which the Hessians suffered one of their worst defeats of the war. In November, the two forts were taken by British land forces, and Commodore John Hazelwood's fleet was then forced to withdraw upriver. Unfavorable winds slowed their progress, and four ships (Montgomery, Delaware, Arnold, and Putnam) were burned to prevent their capture. In April 1778 most of the fleet was destroyed in advance of expected British operations against it. However, news that the British were going to withdraw from Philadelphia led to its resurrection, and in July Captain Hazelwood reported that the brig Convention was ready for action. Its existence as a significant force was limited by the arrival of a French fleet on the North American coast, and in August 1778 the state's assembly voted to sell off most of its remaining ships, keeping only the Convention and a few smaller ships. The smaller ships proved inadequate protection for the trade ships of Pennsylvania's merchants. In response to their petitions, the state authorized the construction of the General Greene in March 1779. Under her captain, James Montgomery, she cruised between New York and the Chesapeake Bay, often in conjunction with Continental Navy ships or privateers, and sent a number of prizes to Philadelphia. According to Montgomery, her crew was virtually unmanageable, and she was sold at the end of the 1779 sailing season. Her unusually low sales price aroused suspicions of collusion in the process. By 1782 the activities of the Royal Navy and Loyalist privateers again spurred Philadelphia's merchants to petition for better naval defenses. This resulted in the commissioning of the Hyder Ally, which was outfitted by the merchants, and placed under the command of the Continental Navy's Joshua Barney. After the successful capture of HMS General Monk, Barney took over her command, renaming her Washington. After a trip to the West Indies, she was sold to the Continental Navy. The Hyder Ally continued to patrol without significant success. By February 1783, with peace appearing to near, most
