In the spring of 1816 Charles sold his wife's property out of the
funds to the amount of nearly four hundred thousand francs, intending
to seek his fortune in America, and abandon his own country where
persecution was beginning to lay a heavy hand on the soldiers of
Napoleon. He went to Havre accompanied by Dumay, whose life he had
saved at Waterloo by taking him on the crupper of his saddle in the
hurly-burly of the retreat. Dumay shared the opinions and the
anxieties of his colonel; the poor fellow idolized the two little
girls and followed Charles like a spaniel. The latter, confidence that
the habit of obedience, the discipline of subordination, and the
honesty and affection of the lieutenant would make him a useful as
well as a faithful retainer, proposed to take him with him in a civil
capacity. Dumay was only too happy to be adopted into the family, to
which he resolved to cling like the mistletoe to an oak.

While waiting for an opportunity to embark, at the same time making
choice of a ship and reflecting on the chances offered by the various
ports for which they sailed, the colonel heard much talk about the
brilliant future which the peace seemed to promise to Havre. As he
listened to these conversations among the merchants, he foresaw the
means of fortune, and without loss of time he set about making himself
the owner of landed property, a banker, and a shipping-merchant. He
bought land and houses in the town, and despatched a vessel to New
York freighted with silks purchased in Lyons at reduced prices. He
sent Dumay on the ship as his agent; and when the latter returned,
after making a double profit by the sale of the silks and the purchase
of cottons at a low valuation, he found the colonel installed with his
family in the handsomest house in the rue Royale, and studying the
principles of banking with the prodigious activity and intelligence of
a native of Provence.
