The author has often been asked if there were any foundation in real
life for the delineation of the principal character in this book. He can
give no clearer answer to the question than by laying before his readers
a simple statement of the facts connected with its original publication.

Many years since, the writer of this volume was at the residence of an
illustrious man, who had been employed in various situations of high
trust during the darkest days of the American Revolution. The discourse
turned upon the effects which great political excitement produces on
character, and the purifying consequences of a love of country, when
that sentiment is powerfully and generally awakened in a people. He who,
from his years, his services, and his knowledge of men, was best
qualified to take the lead in such a conversation, was the principal
speaker. After dwelling on the marked manner in which the great struggle
of the nation, during the war of 1775, had given a new and honorable
direction to the thoughts and practices of multitudes whose time had
formerly been engrossed by the most vulgar concerns of life, he
illustrated his opinions by relating an anecdote, the truth of which he
could attest as a personal witness.

The dispute between England and the United States of America, though not
strictly a family quarrel, had many of the features of a civil war. The
people of the latter were never properly and constitutionally subject to
the people of the former, but the inhabitants of both countries owed
allegiance to a common king. The Americans, as a nation, disavowed this
allegiance, and the English choosing to support their sovereign in the
attempt to regain his power, most of the feelings of an internal
struggle were involved in the conflict. A large proportion of the
emigrants from Europe, then established in the colonies, took part with
the crown; and there were many districts in which their influence,
united to that of the Americans who refused to lay aside their
allegiance, gave a decided preponderance to the royal cause. America was
then too young, and too much in need of every heart and hand, to regard
these partial divisions, small as they were in actual amount, with
indifference. The evil was greatly increased by the activity of the
English in profiting by these internal dissensions; and it became doubly
serious when it was found that attempts were made to raise various corps
of provincial troops, who were to be banded with those from Europe, to
reduce the young republic to subjection. Congress named an especial and
a secret committee, therefore, for the express purpose of defeating this
object. Of this committee Mr.----, the narrator of the anecdote,
was chairman.

In the discharge of the novel duties which now devolved on him, Mr.----
had occasion to employ an agent whose services differed but little from
those of a common spy. This man, as will easily be understood, belonged
to a condition in life which rendered him the least reluctant to appear
in so equivocal a character. He was poor, ignorant, so far as the usual
instruction was concerned; but cool, shrewd, and fearless by nature. It
was his office to learn in what part of the country the agents of the
crown were making their efforts to embody men, to repair to the place,
enlist, appear zealous in the cause he affected to serve, and otherwise
to get possession of as many of the secrets of the enemy as possible.
The last he of course communicated to his employers, who took all the
means in their power to counteract the plans of the English, and
frequently with success.

It will readily be conceived that a service like this was attended with
great personal hazard. In addition to the danger of discovery, there was
the daily risk of falling into the hands of the Americans themselves,
who invariably visited sins of this nature more severely on the natives
of the country than on the Europeans who fell into their hands. In fact,
the agent of Mr. ---- was several times arrested by the local
authorities; and, in one instance, he was actually condemned by his
exasperated countrymen to the gallows. Speedy and private orders to the
jailer alone saved him from an ignominious death. He was permitted to
escape; and this seeming and indeed actual peril was of great aid in
supporting his assumed character among the English. By the Americans, in
his little sphere, he was denounced as a bold and inveterate Tory. In
this manner he continued to serve his country in secret during the early
years of the struggle, hourly environed by danger, and the constant
subject of unmerited opprobrium.

In the year ---, Mr. ---- was named to a high and honorable employment
at a European court. Before vacating his seat in Congress, he reported
to that body an outline of the circumstances related, necessarily
suppressing the name of his agent, and demanding an appropriation in
behalf of a man who had been of so much use, at so great risk. A
suitable sum was voted; and its delivery was confided to the chairman of
the secret committee.

Mr. ---- took the necessary means to summon his agent to a personal
interview. They met in a wood at midnight. Here Mr. ---- complimented
his companion on his fidelity and adroitness; explained the necessity of
their communications being closed; and finally tendered the money. The
other drew back, and declined receiving it. "The country has need of all
its means," he said; "as for myself, I can work, or gain a livelihood in
various ways." Persuasion was useless, for patriotism was uppermost in
the heart of this remarkable individual; and Mr. ---- departed, bearing
with him the gold he had brought, and a deep respect for the man who had
so long hazarded his life, unrequited, for the cause they served
in common.

The writer is under an impression that, at a later day, the agent of
Mr. ---- consented to receive a remuneration for what he had done; but it
was not until his country was entirely in a condition to bestow it.

It is scarcely necessary to add, that an anecdote like this, simply but
forcibly told by one of its principal actors, made a deep impression on
all who heard it. Many years later, circumstances, which it is
unnecessary to relate, and of an entirely adventitious nature, induced
the writer to publish a novel, which proved to be, what he little
foresaw at the time, the first of a tolerably long series. The same
adventitious causes which gave birth to the book determined its scene
and its general character. The former was laid in a foreign country; and
the latter embraced a crude effort to describe foreign manners. When
this tale was published, it became matter of reproach among the author's
friends, that he, an American in heart as in birth, should give to the
world a work which aided perhaps, in some slight degree, to feed the
imaginations of the young and unpracticed among his own countrymen, by
pictures drawn from a state of society so different from that to which
he belonged. The writer, while he knew how much of what he had done was
purely accidental, felt the reproach to be one that, in a measure, was
just. As the only atonement in his power, he determined to inflict a
second book, whose subject should admit of no cavil, not only on the
world, but on himself. He chose patriotism for his theme; and to those
who read this introduction and the book itself, it is scarcely necessary
to add, that he took the hero of the anecdote just related as the best
illustration of his subject.

Since the original publication of _The Spy_, there have appeared several
accounts of different persons who are supposed to have been in the
author's mind while writing the book. As Mr. ---- did not mention the
name of his agent, the writer never knew any more of his identity with
this or that individual, than has been here explained. Both Washington
and Sir Henry Clinton had an unusual number of secret emissaries; in a
war that partook so much of a domestic character, and in which the
contending parties were people of the same blood and language, it could
scarcely be otherwise.

The style of the book has been revised by the author in this edition. In
this respect, he has endeavored to make it more worthy of the favor with
which it has been received; though he is compelled to admit there are
faults so interwoven with the structure of the tale that, as in the case
of a decayed edifice, it would cost perhaps less to reconstruct than to
repair. Five-and-twenty years have been as ages with most things
connected with America. Among other advantages, that of her literature
has not been the least. So little was expected from the publication of
an original work of this description, at the time it was written, that
the first volume of _The Spy_ was actually printed several months,
before the author felt a sufficient inducement to write a line of the
second. The efforts expended on a hopeless task are rarely worthy of him
who makes them, however low it may be necessary to rate the standard of
his general merit.

One other anecdote connected with the history of this book may give the
reader some idea of the hopes of an American author, in the first
quarter of the present century. As the second volume was slowly
printing, from manuscript that was barely dry when it went into the
compositor's hands, the publisher intimated that the work might grow to
a length that would consume the profits. To set his mind at rest, the
last chapter was actually written, printed, and paged, several weeks
before the chapters which precede it were even thought of. This
circumstance, while it cannot excuse, may serve to explain the manner in
which the actors are hurried off the scene.

A great change has come over the country since this book was originally
written. The nation is passing from the gristle into the bone, and the
common mind is beginning to keep even pace with the growth of the body
politic. The march from Vera Cruz to Mexico was made under the orders of
that gallant soldier who, a quarter of a century before, was mentioned
with honor, in the last chapter of this very book. Glorious as was that
march, and brilliant as were its results in a military point of view, a
stride was then made by the nation, in a moral sense, that has hastened
it by an age, in its progress toward real independence and high
political influence. The guns that filled the valley of the Aztecs with
their thunder, have been heard in echoes on the other side of the
Atlantic, producing equally hope or apprehension.

There is now no enemy to fear, but the one that resides within. By
accustoming ourselves to regard even the people as erring beings, and by
using the restraints that wisdom has adduced from experience, there is
much reason to hope that the same Providence which has so well aided us
in our infancy, may continue to smile on our manhood.
