natural allegiance, as that, provided the jurisdiction of another
independent state be not infringed, every nation has a right to
enforce the services of her subjects wherever they may be found.
Nor has any neutral nation such a jurisdiction over her merchant
vessels upon the high seas as to exclude a belligerent nation from
the right of searching them for contraband of war or for the property
or persons of her enemies. And if, in the exercise of that right,
the belligerent should discover on board of the neutral vessel a
subject who has withdrawn himself from his lawful allegiance, the
neutral can have no fair ground for refusing to deliver him up;
more especially if that subject is proved to be a deserter from
the sea or land service of the former." [Footnote: "The Naval History
of Great Britain," by William James, vol. iv, p. 324. (New edition
by Captain Chamier, R. N., London, 1837.)]

Great Britain's doctrine was "once a subject always a subject." On
the other hand, the United States maintained that any foreigner,
after five years' residence within her territory, and after having
complied with certain forms, became one of her citizens as completely
as if he was native born. Great Britain contended that her war
ships possessed the right of searching all neutral vessels for the
property and persons of her foes. The United States, resisting this
claim, asserted that "free bottoms made free goods," and that
consequently her ships when on the high seas should not be molested
on any pretext whatever. Finally, Great Britain's system of
impressment, [Footnote: The best idea of which can be gained by
reading Marryatt's novels.] by which men could be forcibly seized
and made to serve in her navy, no matter at what cost to themselves,
was repugnant to every American idea.
