[Footnote 226: As the seizure of all these articles is, according to article 53 of the Hague Regulations, permissible in occupied enemy country, provided they are restored and indemnities paid after the conclusion of peace, seizure must likewise--under the same conditions--be permissible in case these articles are on the territory of a belligerent. As regards rolling stock belonging to private enemy railway companies, see Nowacki, _Die Eisenbahnen im Kriege_ (1906), § 15.] [Sidenote: Effect of the Outbreak of War on Merchantmen.] § 102_a_. In former times International Law empowered States at the outbreak of war to lay an embargo upon all enemy merchantmen in their harbours in order to confiscate them. And enemy merchantmen on the sea could at the outbreak of war be captured and confiscated although they did not even know of the outbreak of war. As regards enemy merchantmen in the harbours of the belligerents, it became, from the outbreak of the Crimean War in 1854, a usage, if not a custom, that no embargo[227] could be laid on them for the purpose of confiscating them, and that a reasonable time must be granted them to depart unmolested; but no rule was in existence until the Second Peace Conference of 1907 which prescribed immunity from confiscation for such enemy merchantmen at sea as did not know of the outbreak of war. This Conference took the matter into consideration, and produced a Convention (VI.) relative to the status of enemy merchantmen at the outbreak of hostilities[228] which is signed by all the Powers represented at the Conference, except the United States of America,[229] China, and Nicaragua; but Nicaragua acceded later. In coming to an agreement on the subject, two facts had to be taken into consideration. There is, firstly, the fact that in all maritime countries numerous merchantmen are now built from special designs in order that they may quickly, at the outbreak of or during war, be converted into cruisers; it would therefore be folly on the part of a belligerent to grant any lenient treatment to such vessels. There is, secondly, the fact, that a belligerent fleet cannot nowadays remain effective for long without being accompanied by a train of colliers, transport vessels, and repairing vessels; it is, therefore, of the greatest importance for a belligerent to have as many merchantmen as possible at his disposal for the purpose of making use of them for such assistance to the fleet. For this reason, Convention VI. represents a compromise, and it distinguishes between vessels in the harbours of the belligerents and vessels on the sea. Its provisions are the following:-- [Footnote 227: See above, § 40.] [Footnote 228: See Lémonon, pp. 647-661; Higgins, pp. 300-307; Nippold, II. pp. 146-153; Scott, _Conferences_, pp. 556-568; Dupuis, _Guerre_, Nos. 74-81; Scott in _A.J._ II.
