The battle of Monmouth, which took place on the 28th of June, was widely scattered in its action over a hot and sandy plain. The outcome was that General Lee first brought his troops face to face with the enemy, and then, instead of leading on to the attack, gave the order for retreat. Afterwards, in the court-martial of Lee, it was made evident that the movement of the troops as ordered by Lee would have left Lafayette and his detachment abandoned in an extremely exposed position on the open plain, the troops that should have supported him having been withdrawn by Lee's orders and directed to retreat. Lafayette and the other generals felt great bitterness on that day because they had been swept into battle but had not been allowed to strike a blow.
Everybody knows how Washington rode up, and when he saw the retreat, how he indignantly reproved General Lee and commanded the battalions to turn back and form in position for battle. Lafayette was in command of a division stationed at the second line under Lord Stirling who sustained the left wing; they were now placed on an eminence behind a morass and there played the batteries to such good effect that they were able to check the advance of the British. This halt gave Washington time to place his army to advantage. The British were driven from a strong position they had taken, and before dark the American troops had turned the British back. That night they lay upon the field in bright moonlight, and while Washington and Lafayette discussed the possible outcome of the next day, the British were silently withdrawing from the Monmouth plains. The next morning all had disappeared except some forty of their wounded. At Sandy Hook, where the British army crossed to New York, it was learned that they had lost about two thousand men by desertions and by losses at Monmouth. Many of the soldiers on both sides had died from the extreme heat on that 28th of June.
During the battle Lafayette was master of himself. Almost fifty years later, Colonel Willett related that in the hottest of the fight he saw Lafayette ride up to one of the officers and, in a voice cool, steady, and slow, and with as much deliberation as if nothing exciting prevailed, say,
"General, the enemy is making an attempt to cut off our right wing; march to his assistance with all your force."
So saying he galloped off. Colonel Willett remembered that he was exceedingly well mounted, though plainly dressed, and "very sedate in his air for a Frenchman."
A number of situations arose soon after this in which Lafayette found himself of great use. The French fleet under Count d'Estaing appeared near Delaware Bay and sailed up the coast. Washington was at White Plains. The British held New York. It was thought that the French fleet could accomplish much by going to Newport and there coöperating with the land forces. Lafayette was given a detachment and commanded to proceed to Providence where he was to stand ready to give all possible aid.
But he was doomed to still another disappointment. The French fleet arrived off Point Judith near Newport; visits of ceremony were exchanged by the French and American generals; preparations were made; but through misunderstandings, the plans never worked out to an actual engagement. Before anything was accomplished, a severe storm overtook the fleet, and it withdrew to Boston for necessary repairs.
During this trying time, Lafayette was a trusted resource to Washington, who devoutly wished to reconcile all differences and to bring peace out of dissension. For this Lafayette had peculiar qualities, as he understood the character of both the French and the Americans, and believed absolutely in the good intentions of the officers on both sides. Twice he rode to Boston and back again to help in settling some difficulty, making on one of those occasions a journey of seventy miles, at night, in six and a half hours—a feat paralleled only by Sheridan's famous ride to Winchester.
But the fleet sailed away, bearing many disappointments with it, though much good had been done by its coming; it meant that the American cause had received definite encouragement from France.
It was now October of 1778 and autumn weather was closing the campaign of the year. The sending of the French fleet to our shores had been virtually a declaration that a state of war existed between France and England, and the thought that this might develop into an actual war in which Lafayette, after his practical experience and training in the Continental army, could take part and win glory, inclined him strongly at this point to return to his native land. Permission was given to him to do this. The proper farewells, official and private, were made, and Lafayette started on his way to Boston where he was to embark.
