The French equipped at Toulon a fleet of twelve sail of the line and six frigates, and gave the command to Count D'Estaing, who, with a considerable number of troops on board, sailed on the 13th of April (1778); but meeting with contrary winds he did not reach the coast of America till the 5th of July. He expected to find the British army in Philadelphia and the fleet in the Delaware, and if this expectation had been realized the consequences to Britain must have been calamitous. But the British fleet and army were at Sandy Hook or New York before the French fleet arrived on the coast. Count D'Estaing touched at the capes of the Delaware on the 5th of July, and on learning that the British had evacuated Philadelphia, he dispatched one of his frigates up the river with M. Gerard, the first minister from France to the United States, and then sailed for Sandy Hook. Washington received intelligence of D'Estaing's arrival in a letter from the President of Congress while he was at Paramus. The next day he received a second letter on the same subject, enclosing two resolutions--one directing him to cooperate with the French admiral and the other authorizing him to call on the States from New Hampshire to New Jersey, inclusive, for such aids of militia as he might deem necessary for the operations of the allied arms. He determined to proceed immediately to White Plains, whence the army might cooperate with more facility in the execution of any attempt which might be made by the fleet, and dispatched Lieutenant-Colonel Laurens, one of his aides-de-camp, with all the information relative to the enemy, as well as to his own army, which might be useful to D'Estaing. Lieutenant-Colonel Laurens was authorized to consult on future conjoint operations, and to establish conventional signals for the purpose of facilitating the communication of intelligence. The French admiral, on arriving off the Hook, dispatched Major de Choisi, a gentleman of his family, to Washington for the purpose of communicating fully his views and his strength. His first object was to attack New York. If this should be found impracticable, he was desirous of turning his attention to Rhode Island. To assist in coming to a result on these enterprises, Washington dispatched Lieutenant-Colonel Hamilton, another of his aides-de-camp, with such further communications as had been suggested by inquiries made since the departure of Laurens.
