Historical Background

William Dobbs was a pilot from Fishkill, New York. In 1779, Washington engaged Dobbs to act as a pilot for French Admiral Hector D'Estaing upon his arrival. This agreement was renewed, though the French Navy did not actually collaborate with the Continental Army until the famous Yorktown campaign of 1781. On May 2, 1780 Admiral de Ternay (d'Estaing having returned to France), in command of a division of seven ships, sailed from Brest, carrying a total of 6,000 men under the command of Lieutenant General de Rochambeau. Ternay's orders specified Newport, Rhode Island, as his destination unless he found the island to be already occupied by the British. He arrived on July 12. For much of 1780 and early 1781, the French Navy and Rochambeau's Expeditionary Army were bottled up in Newport, Rhode Island, by British blockade.

Washington, as is argued by historian Joseph Ellis, envisioned collaboration between his army, Rochambeau, and the French Navy, but his real object was New York City, the site of Washington's most humiliating defeat to date. He could expunge his demons by delivering the decisive blow for American independence. As Washington wrote to Nathanael Greene three days after this letter, he had "determined upon a plan of operations for the reduction of the City and Garrison of New York" with French assistance. He knew the French Navy would need skilled pilots, knowledgeable of the idiosyncrasies of the Hudson River and New York harbor, and Dobbs was ideal. As this letter shows, Washington wanted Dobbs to bring more pilots. On July 15, he dispatched the Marquis de Lafayette with a "Memorandum for Concerting a Plan of Operations" to Rochambeau, which detailed his plan to invest New York. Washington stated that it was "essential for us to be Masters of the Navigation of the No[rth, or Hudson]. River and of the [Long Island] Sound."

Most of the consequential combat took place in the South in 1780. British Commander-in-Chief Sir Henry Clinton captured Charleston, South Carolina on May 12, 1780, and left his chief subordinate, Lord Cornwallis, to subdue the Carolinas and protect Loyalists. Clinton returned to New York City on June 17 and received a message from the traitor Benedict Arnold, the American commandant of West Point, that Rochambeau's troops were on their way to join the Patriot cause (they were not). Clinton therefore ordered an advance on Springfield, New Jersey, to occupy Washington and prevent any potential union. This advance, one of the last to take place in New Jersey, forced Washington to remain in New Jersey for most of July, making his headquarters at Colonel Dey's home (located in present-day Wayne, New Jersey). Clinton also wanted to gain time for his troops to return from Charleston, after which he planned to launch an offensive in the Hudson Highlands, with Arnold's treacherous assistance.
