the nation, defensive or the contrary, we are confronted by an event
as remarkable in its nature as it is epoch-making in its consequences.
Magna Charta was sealed on the 13th of June 1215, and within a year of
that date, on, namely, the 14th of April then next ensuing, King John
issued his commission to the barons of twenty-two seaports, requiring
them, in terms admitting of neither misconstruction nor compromise, to
arrest all ships, and to assemble those ships, together with their
companies, in the River of Thames before a certain day. [Footnote:
Hardy, _Rotuli Litterarum Clausarum_, 1833.] This wholesale
embargo upon the shipping and seamen of the nation, imposed as it was
immediately after the ensealing of Magna Charta, raises a question of
great constitutional interest. In what sense, and to what extent, was
the Charter of English Liberties intended to apply to the seafaring
man?

Essentially a tyrant and a ruthless promise-breaker, John's natural
cruelty would in itself sufficiently account for the dire penalties
threatened under the warrant of 1208; but neither his tyranny, his
faithlessness of character, nor his very human irritation at the
concessions wrung from him by his barons, can explain to our
satisfaction why, having granted a charter affirming and safeguarding
the liberties of, ostensibly, every class of his people, he should
immediately inflict upon one of those classes, and that, too, the one
least of all concerned in his historic dispute, the pains of a most
rigorous impressment. The only rational explanation of his conduct is,
that in thus acting he was contravening no convention, doing violence
to no covenant, but was, on the contrary, merely exercising, in
accordance with time-honoured usage, an already well-recognised,
clearly denned and firmly seated prerogative which the great charter
he had so recently put his hand to was in no sense intended to limit
