SECTION III.

_Blockades. Right of Search. Convoys_.

[Sidenote: Blockades.]

We now pass on to the subject of Blockade, which is the next exception

to the general freedom of neutral commerce in time of war.

A blockade is a high act of Sovran authority; it cannot be assumed or

exercised by a commander, without special authority, provided his

Government is sufficiently near at hand to superintend and direct the

course of operations; but a commander on a distant station is supposed

to carry with him such a portion of the Sovran authority as may enable

him to act with energy against the commerce of the enemy, as against

the enemy himself.[184]

Again, referring to Sir Wm. Scott's celebrated judgments, we find him

saying,

"That to constitute a violation of a state of blockade,

three things must be proved: first, the existence of the

blockade; secondly, the knowledge of it, in the party

supposed to have offended; and thirdly, some act of

violation, either by going in, or coming out with a cargo,

laden after the commencement of the blockade."

[Sidenote: First Rule of Blockade.]

I. There is no rule of law more established than this; that the Breach

of a Blockade subjects the property so employed to confiscation. Every

man knows it; the subjects of all states know it.

A lawful maritime blockade requires the actual presence of a

sufficient force stationed at the entrance of the port, sufficiently

near to prevent communication.

The blockade is to be considered legally existing, although the winds

may occasionally blow off the blockading squadron. It is an accidental

change which must take place in every blockade; but the blockade is

not therefore suspended.

This axiom is laid down in all books of authority; and the law

considers an attempt to take advantage of such an accidental removal

as an attempt to break the blockade, and a mere fraud.[185]

When a blockading squadron is driven off by a superior force, the

blockade is effectually raised, and it must be renewed by fresh

notification, before foreign nations can be affected by an obligation

to observe it as a blockade. The mere appearance of another squadron

will not renew it, but it must be restored by the measures required

for the original imposition of a blockade.[186]

[Sidenote: Second Rule of Blockade.]

It is necessary that the evidence of a blockade should be clear and

decisive. A blockade may exist without a public declaration; although

a declaration, unsupported by fact, will not be sufficient to

establish it. In the War of 1798, the West India Islands were declared

under blockade by Admiral Jervis; but the Lords of the Supreme Court

held, that as the fact did not support the declaration, a blockade

could not be deemed legally to exist. But the fact, on the contrary,

duly notified on the spot, is of itself sufficient; for public

notifications between governments are meant for the information of

individuals; but if the individual is _personally_ informed, that

purpose is better obtained than by a public declaration.[187]

Where the vessel sails from a country lying near enough to the

blockaded port to have constant information of the blockade, no notice

is necessary of its continuance or relaxation; but when the country is

at a distance beyond constant information, they may lawfully send

their vessels on conjecture that the blockade is broken up, after it

has existed a long time.[188] And this is important, as it must be

remembered that even the _intention_ to evade blockade is a fraudulent

breach of it, and sailing towards the port is an _overt_ act of that

intent.[189]

There are two kinds of Blockade. 1. Simple Blockade, _i.e._ Blockade

in Fact; and 2nd., Blockade in Fact, accompanied by a Notification.

The first expires by the breaking up _intentionally_ of the blockading

squadron. The second, _prima facie_, does not expire until the repeal

of the notification, but it is the duty of the belligerent country

directly the blockade ceases, _de facto_, to revoke its proclamation.

And it would appear that a notified blockade would only expire, in

fact, after some unnecessary and long neglect to publish this

revocation; otherwise neutral nations are bound until such

publication.[190]

It has from time to time been stipulated, in treaties between

belligerent and neutral countries, (as in the case of the Treaty

between Great Britain and the United States, of 1794,) that vessels of

the neutral country should not be considered as having notice of a

blockade, until they have been duly and respectfully warned off; and

it would only be on a second attempt to enter port that they would be

liable to be seized. Under such a treaty a neutral vessel might

lawfully sail for a blockaded port, knowing it to be blockaded.[191]

[Sidenote: Third Rule of Blockade.]

An act of Violation is essential to a Breach of Blockade; such as,

either going in or coming out of the port with a cargo, laden after

the commencement of the blockade: or being found so near to the

blockaded port as to show, beyond a doubt, that the vessel was

endeavouring to run into it: or where the intention is expressly

avowed by the papers found on board.[192]

The time of shipment is very material; for although it may be hard to

refuse a Neutral, liberty to retire with a cargo already laden, and by

that act already become neutral property,--yet, after the commencement

of a blockade, a neutral cannot be allowed to interpose in any way to

assist the exportation of the property of the enemy. After the

commencement of a blockade, a Neutral is no longer at liberty to make

any purchase in that port.[193]

A _Maritime_ Blockade is not in law violated by bringing or sending

goods to the port through the internal canal navigation or land

carriage of the country; and thus such goods are not liable to

confiscation on ground of the blockade.

[Sidenote: Right of Search.]

On the great question of the Right of Search, the International Law

has been summed up by Lord Stowell, in the case of the _Maria_, where

the exercise of the right was attempted to be resisted, by the

interposition of a convoy of Swedish ships of war.[194]

First, the right of visiting and searching merchant ships on the high

seas, whatever be the ships, whatever be the cargoes, whatever be the

destinations, is the incontestible right of the lawfully commissioned

cruizers of a belligerent nation.

Secondly, that the authority of the Sovran of the neutral country,

being interposed in any manner of mere force, cannot legally vary the

rights of a lawfully commissioned belligerent cruizer. It cannot be

maintained, that if a Swedish commissioned cruizer, during the wars of

his own country, has a right, by the Laws of Nations, to visit and

examine neutral ships, the King of England, (being Neutral to Sweden,)

is authorized by law to obstruct the exercise of that right with

respect to the merchants' ships of his country.

Thirdly, that the penalty for the violent contravention of this right,

is the confiscation of the property withheld from visitation and

search.

The judgment of condemnation, pronounced in this case, was followed by

the Treaty of Armed Neutrality entered into by the Baltic Powers to

resist the Right of Search, in 1800, which league was dissolved by the

death of the Emperor Paul, and the points in controversy between those

Powers and Great Britain were finally adjusted by the Convention of

5th of June, 1805.[195]

[Sidenote: Convoys.]

It now remains to say a few words on the subject of Convoy. Convoy is

a ship or ships of war appointed by the Government, or by the

Commander-in-Chief on a particular station, for the guard of merchant

vessels bound to their destination. A warranty that the vessel shall

sail with convoy, is very common in Policies of Insurance, and if not

complied with, the Insurance becomes absolutely void.

This warranty to sail with convoy, does not mean that the vessel shall

depart with convoy immediately from the lading port, but only from the

place of rendezvous appointed for vessels bound from that port, and

must be strictly and impartially maintained by force, to the uniform

universal exclusion of all vessels not privileged by law.[196]

From many ports, and among others from the port of London, no convoy

ever sails. It has therefore been held sufficient for a vessel bound

from London to sail with convoy from the _Downs_, and even from

_Spithead_, when there was no convoy appointed from the _Downs_.

Neither does it require the vessel to sail with convoy bound to the

precise place of her destination; but if the vessel sail with the only

convoy appointed for vessels going to her place of destination, it is

sufficient. It sometimes happens that the force first appointed, is to

accompany the ships only for a part of their voyage, and to be

succeeded by another; at other times a small force is detached from

the main body to bring up to a particular point; if a vessel sail

under the protection of a vessel thus appointed or detached, the

warranty is satisfied.

But this warranty requires not only that the vessel shall sail under

the protection of the convoy, but also that she shall continue during

its course under the same protection, unless prevented from so doing

by tempest or other unavoidable accident, in which case, the master

and owners will be excused, if the master does all that is in his

power to keep with the convoy.

The merchantman must, before sailing, obtain or endeavour to obtain,

the sailing orders issued by the convoying squadron. The value of a

convoy appointed by Government arises in a great degree from its

taking the ships under control, as well as under protection; but this

control cannot be exercised except by means of sailing orders.

Otherwise, the master could not learn the rendezvous in case of

dispersion by a storm, or obey signals in case of attack.

The obligation to sail with convoy does not depend merely on special

agreement; but, by act of parliament, a merchant cannot sail without a

convoy, on a _foreign_ voyage, unless previously licensed to do

so.[197]
