General Washington expressed his sense of this brilliant affair in his orders of the 15th, Head Quarters, before York-Town. "The Marquis Lafayette's division will mount the trenches tomorrow. The commander in chief congratulates the allied army on the success of the enterprise, last evening, against the two important redoubts on the left of the enemy's works. He requests the Baron Viominel who commanded the French grenadiers, and the Marquis Lafayette, who commanded the American Light Infantry, to accept his warmest acknowledgments for the excellence of their dispositions, and for their own gallant conduct on the occasion. And he begs them to present his thanks to every individual officer and to the men of their respective commands, for the spirit and rapidity with which they advanced to the points of attack assigned them, and for the admirable firmness with which they supported them, under the fire of the enemy, without returning a shot. The General reflects with the highest pleasure on the confidence which the troops of the two nations must hereafter have in each other: assured of mutual support, he is convinced there is no danger which they will not cheerfully encounter; no difficulty which they will not bravely overcome." If the Marquis de Lafayette was animated by an ardent love of civil liberty, when he first came to America, his attachment to its principles must have become more firm and settled, if not more intense, after an acquaintance of five years, with the patriots and heroes of our revolution. He had become acquainted with our institutions, and with the principles of our government; and was probably led to believe that systems equally free might be maintained in other countries. He was so enamoured, not only with the theory, but with the practical effects, of republicanism, that he felt it a duty to recommend systems of government more consonant to the rights of mankind. We know not, if he justly appreciated the importance of the general diffusion of knowledge among all classes of people, to ensure such a happy state of society. It was probably owing to this consideration, however, that he did not immediately attempt the reformation of the political system under which his own nation had long been oppressed. That Louis XVI. was mild, humane, and anxious for the good of his subjects, we are not disposed to doubt. But the ancient regime was unquestionably despotic; and in the hands of ambitious or selfish ministers, liable to be an instrument of injustice and oppression. And those who have long been accustomed to govern, without being accountable for their conduct, will not easily be induced to relinquish power, from any considerations of abstract right, or a belief that others will be more just. We will here present a letter of Lafayette, directed to Sir H. Clinton; to show his regard to truth, and to his own reputation suffering in some measure by a statement which had been publicly made by that military officer.
