At Trenton Lafayette stopped to resign his commission in the American army, and Congress sent a committee made up of one representative from each State to express the thanks of the nation. Then he returned to Washington’s estate on the banks of the Potomac, and there walked over the beautiful grounds of Mount Vernon, discussing agriculture with the owner, and sat with the latter in his library, listening to Washington’s hopes concerning the young nation for which both men had done so much. History shows no more ideal friendship than that between the great American and the great Frenchman, a friendship of inestimable value for the two lands from which they sprang.

When the time came for parting Washington drove his guest as far as Annapolis in his carriage. There the two friends separated, not to meet again. Washington went back to Mount Vernon, and there wrote a farewell letter to Lafayette. “In the moment of our separation,” he said, “upon the road as I traveled and every hour since, I have felt all that love, respect, and attachment for you, with which length of years, close connection, and your merits have inspired me.... It is unnecessary, I persuade myself, to repeat to you, my dear marquis, the sincerity of my regards and friendship, nor have I words which could express my affection for you, were I to attempt it. My fervent prayers are offered for your safe and pleasant passage, a happy meeting with Madame de Lafayette and family, and the completion of every wish of your heart.”

Lafayette answered after he had gone on board the Nymphe at New York. “Adieu, adieu, my dear general,” said he. “It is with inexpressible pain that I feel I am going to be severed from you by the Atlantic. Everything that admiration, respect, gratitude, friendship, and filial love can inspire is combined in my affectionate heart to devote me most tenderly to you. In your friendship I find a delight which words cannot express. Adieu, my dear general. It is not without emotion that I write this word. Be attentive to your health. Let me hear from you every month. Adieu, adieu.”

On Christmas Day, 1784, Lafayette sailed for France, expecting to return to his adopted country in a few years. He was not to return, however, for a long time, and in the interval much was to happen to himself and his own land.

In the following summer the Marquis made a journey through Germany and Austria, where he was received not only as a French field-marshal, but as an informal representative of America and a friend of Washington, who could answer the questions about the new republic which every one was eager to ask. At Brunswick he visited the duke who was later to lead the German troops against the army of revolutionary France. At Potsdam he was entertained by Frederick the Great, who happened on one occasion to place Lafayette between the English Duke of York and Lord Cornwallis at table. Lafayette was, as always, delightful company, and the general he had defeated at Yorktown wrote home to a friend in England, “Lafayette and I were the best friends possible in Silesia.”

The Frenchman saw reviews of the Prussian armies, and was much impressed by the discipline of Frederick the Great. But he did not like that ruler, and spoke of his “despotic, selfish, and harsh character,” and he liked his military system still less. He wrote to General Knox, “The mode of recruiting is despotic; there is hardly any provision for old soldiers, and although I found much to admire, I had rather be the last farmer in America than the first general in Berlin.”

From Prussia he went to Austria, where he met the emperor, and there, as in all his travels, he told every one of his admiration for the United States and for Washington, and tried to make them see how much the young republic had already accomplished for the happiness of men.

The love of liberty was the dominant motive of Lafayette’s life. He had told Washington of his desire to find some means of securing the freedom of slaves, and he wrote to John Adams in 1786, “Whatever be the complexion of the enslaved, it does not in my opinion alter the complexion of the crime the enslaver commits,—a crime much blacker than any African face. It is to me a matter of great anxiety and concern to find that this trade is sometimes perpetrated under the flag of liberty, our dear and noble stripes to which virtue and glory have been constant standard-bearers.” So, on his return to France, he bought a plantation in Cayenne, and brought many negroes there, who, after being educated in self-government according to his directions, were to receive their freedom. He also tried to improve the condition of the French Protestants, who were very much persecuted, and ardently pleaded their cause before the King at Versailles.

In the meantime he constantly gave his help to furthering the affairs of America. Thomas Jefferson, the author of the Declaration of Independence, who had been Governor of Virginia when Lafayette had fought his campaign there, was now the United States Minister to France. Jefferson wrote to Washington, “The Marquis de Lafayette is a most valuable auxiliary to me. His zeal is unbounded and his weight with those in power is great.... He has a great deal of sound genius, is well remarked by the King, and rising in popularity. He has nothing against him but the suspicion of republican principles. I think he will one day be of the ministry.”

The United States at that time especially needed aid in establishing trade relations with France, and it was here that Lafayette proved himself very valuable. He obtained concessions in regard to the importing and sale of oil and tobacco, and his efforts on behalf of the American whale fishery were so successful that the citizens of Nantucket voted at a town-meeting that every man on the island who owned a cow should give all of one day’s milk toward making a cheese to weigh five hundred pounds, and that the cheese should be “transmitted to the Marquis de Lafayette, as a feeble, but not less sincere, testimonial of their affection and gratitude.”
