The future marshal of France had been first destined to priesthood for no other reason than that he was a second son, and he was about to receive the tonsure when his elder brother died, and Bishop de Crussol, who had been supervising Donatien's ecclesiastical studies, came one day to him and said: "You must forget all I have told you up to now; you have become the eldest of your family and you must now serve your country with as much zeal as you would have served God in the ecclesiastical state."

Rochambeau did so. He was appointed an officer and served on his first campaign in Germany at sixteen, fought under Marshal de Saxe, was a colonel at twenty-two (Washington was to become one also at twenty-two), received at Laufeldt his two first wounds, of which he nearly died. At the head of the famous Auvergne regiment, "Auvergne sans tache" (Auvergne the spotless), as it was called, he took part in the chief battles of the Seven Years' War, notably in the victory of Klostercamp, where spotless Auvergne had 58 officers and 800 soldiers killed or wounded, the battle made memorable by the episode of the Chevalier d'Assas, who went to his heroic death in the fulfilment of an order given by Rochambeau. The latter was again severely wounded, but, leaning on two soldiers, he could remain at his post till the day was won.

On the opposite side of the same battle-fields were fighting many destined, like Rochambeau himself, to take part in the American war; it was like a preliminary rehearsal of the drama that was to be. At the second battle of Minden, in 1759, where the father of Lafayette was killed, Rochambeau covered the retreat, while in the English ranks Lord Cornwallis was learning his trade, as was too, but less brilliantly, Lord George Germain, the future colonial secretary of the Yorktown period. At Johannisberg, in the same war, Clinton, future commander-in-chief at New York, was wounded, while here and there in the French army such officers distinguished themselves as Bougainville, back from Ticonderoga, and not yet a sailor, Chastellux, already a colonel, no longer a secretary of embassy, not yet an Academician, and my predecessor, La Luzerne, an officer of cavalry, not yet a diplomat, who was to be the second minister ever accredited to America, where his name is not forgotten.

When still very young Rochambeau had contracted one of those marriages so numerous in the eighteenth, as in every other century, of which nothing is said in the memoirs and letters of the period, because they were what they should be, happy ones. Every right-minded and right-hearted man will find less pleasure in the sauciest anecdote told by Lauzun than in the simple and brief lines written in his old age by Rochambeau: "My good star gave me such a wife as I could desire; she has been for me a cause of constant happiness throughout life, and I hope, on my side, to have made her happy by the tenderest amity, which has never varied an instant during nearly sixty years." The issue of that union, Viscount Rochambeau, from his youth the companion in arms of his father, an officer at fourteen, accompanied him to the States, and was, after a career of devotion to his country, to die a general at Leipzig, in the "Battle of Nations."

Informed at Versailles of the task he would have to perform, the exact nature of which was kept a secret from the troops themselves now gathered at Brest, Rochambeau hastened to forget his "rhumatisme inflammatoire" and set to work to get everything in readiness, collecting information, talking with those who knew America, and noting down in his green-garbed registers, which were to accompany him in his campaign, the chief data thus secured. He also addressed to himself, as a reminder, a number of useful recommendations such as these: "To take with us a quantity of flints, ... much flour and biscuit; have bricks as ballast for the ships, to be used for ovens; to try to bring with us all we want and not to have to ask from the Americans who are themselves in want ... to have a copy of the Atlas brought from Philadelphia by Mr. de Lafayette ... to have a portable printing-press, like that of Mr. d'Estaing, handy for proclamations ... siege artillery is indispensable." Some of the notes are of grave import and were not lost sight of throughout the campaign: "Nothing without naval supremacy."

To those intrusted with the care of loading the vessels he recommends that all articles of the same kind be not placed on the same ship, "so that in case of mishap to any ship the whole supply of any kind of provisions be not totally lost."

As to the pay for himself and his officers, he writes to the minister that he leaves that to him: "Neither I nor mine desire anything extravagant; we should like to be able to go to this war at our own expense." But the government did not want him to be hampered by any lack of funds, and allotted him the then considerable sum of twelve thousand francs a month, and four thousand a month the generals under him.

At Brest, where he now repaired, Rochambeau found that the ships were not so numerous as expected, so that only the first division of his army could embark under Admiral Chevalier de Ternay: a sad blow for the commander-in-chief. He prescribed that care be at least taken to select for the passage the most robust men, and, in order to save space, that all horses be left behind, himself giving the example. "I have," Rochambeau writes to Prince de Montbarey, the minister of war, "to part company with two battle-horses that I can never replace. I do so with the greatest sorrow, but I do not want to have to reproach myself with their having taken up the room of twenty men who could have embarked in their stead." Officers, soldiers, ammunition, artillery, spare clothing for the troops, and even the printing-press go on board at last. Men and things are close-packed, but end by shaking down into place; all will go well, Rochambeau writes to the minister, "without any overcrowding of the troops; the rule for long journeys having been observed, namely one soldier for every two tons burden."

When all were there, however, forming a total of 5,000 men, the maximum was so truly reached that a number of young men, some belonging to the best-known French families, who were arriving at Brest from day to day, in the hope of being added to the expedition, had to be sent back. The fleet was already on the high seas when a cutter brought the government's last instructions to Rochambeau. On the boat were two brothers called Berthier, who besought to be allowed to volunteer. "They have joined us yesterday," the general writes to the minister, "and have handed us your letters.... They were dressed in linen vests and breeches, asking to be admitted as mere sailors." But there was really no place to put them. "Those poor young men are interesting and in despair." They had, nevertheless, to be sent back, but managed to join the army later, and so it was that Alexander Berthier began in the Yorktown campaign a military career which he was to end as marshal of France, and Prince of Wagram and Neufchâtel.

The departure, which it was necessary to hasten while the English were not yet ready, was beset with difficulties. Tempests, contrary winds and other mishaps had caused vexatious delay; the Comtesse de Noailles and the Conquérant had come into collision and had had to be repaired. "Luckily," wrote Rochambeau to Montbarey, with his usual good humor, "it rains also on Portsmouth." At last, on the 2d of May, 1780, the fleet of seven ships of the line and two frigates conveying thirty-six transports, weighed anchor for good. "We shall have the start of Graves," the general wrote again, "for he will have to use the same wind to leave Portsmouth," and he added, with a touch of emotion at this solemn moment: "I recommend this expedition to the friendship of my dear old comrade, and to his zeal for the good of the state."
