Howe now determined to make a general sweep of all the American works on the Delaware, and, preparatory thereto, he called in his outposts and concentrated his whole army near to and within Philadelphia. Two Rhode Island regiments, belonging to General Varnum's *** brigade, under Colonel Christopher Greene, garrisoned the fort at Red Bank, and

** This cut, copied from an old print, shows the form of the chevaux de frisé. A is a profile view, and B a plan. The spikes were made of heavy timbers, about thirty feet in length. Partially filled with heavy stone, they presented a formidable obstacle to vessels. It is said that these obstructions were mainly planned by Dr. Franklin, and constructed under the immediate supervision of M. Du Plessis Manduit, a French engineer.
*** James Mitchell Varnum was born at Dracut, Massachusetts, in 1749, and graduated in the first class at Providence College in 1769. He afterward studied law at East Greenwich, became an active politician in Rhode Island, espoused the patriot cause, and joined the army in 1775. In February, 1777, he was commissioned a brigadier in the Continental service. He served under Sullivan in the operations on Rhode Island, in 1778, and the next year resigned his commission and left the army. He was a delegate to Congress in 1786, and the following year was appointed a judge of the Northwestern Territory. He died at Marietta, Ohio, January 10, 1790, aged forty-one. His brother, Joseph Bradley Varnum, was also an officer in the Revolution; a member, from Massachusetts, of the first Congress after the adoption of the Federal Constitution; was four years speaker of the Lower House, and succeeded Timothy Pickering as United States senator in 1811. He died on the 11th of September, 1821, aged seventy-one years.

The American fleet in the river, consisting chiefly of galleys and floating batteries, was commanded by Commodore Hazlewood. * It was quite as important to the Americans to maintain these forts and defend the river obstructions as it was to the British to destroy them. It was therefore determined to hold them to the last extremity, for it was evident that such continued possession would force Howe to evacuate Philadelphia.
