The Signatory Powers shall take the necessary steps in order to bring the provisions of the present Convention to the knowledge of their naval forces, and especially of the members ent.i.tled thereunder to immunity, and to make them known to the public.

_Article 21_

The Signatory Powers likewise undertake to enact or to propose to their Legislatures, if their criminal laws are inadequate, the measures necessary for checking in time of war individual acts of pillage and ill-treatment in respect to the sick and wounded in the fleet, as well as for punishing as an unjustifiable adoption of naval or military marks, the unauthorised use of the distinctive marks mentioned in Article 5, by vessels not protected by the present Convention.

They shall communicate to each other, through the Netherland Government, the enactments for preventing such acts at the latest within five years of the ratification of the present Convention.

_Article 22_

In the case of operations of war between the land and sea forces of belligerents, the provisions of the present Convention are only applicable to the forces on board ship.

_Article 23_

The present Convention shall be ratified as soon as possible.

The ratifications shall be deposited at The Hague.

The first deposit of ratifications shall be recorded in a Protocol signed by the Representatives of the Powers which take part therein and by the Netherland Minister for Foreign Affairs.

The subsequent deposits of ratifications shall be made by means of a written notification, addressed to the Netherland Government and accompanied by the instrument of ratification.

A duly certified copy of the Protocol relating to the first deposit of ratifications, of the notifications mentioned in the preceding paragraph, and of the instruments of ratification, shall be immediately sent by the Netherland Government through the diplomatic channel to the Powers invited to the Second Peace Conference, as well as to the other Powers which have acceded to the Convention. The said Government shall, in the cases contemplated in the preceding paragraph, inform them at the same time of the date on which it received the notification.

_Article 24_

Non-Signatory Powers which have accepted the Geneva Convention of July 6, 1906, may accede to the present Convention.

A Power which desires to accede notifies its intention in writing to the Netherland Government, forwarding to it the act of accession, which shall be deposited in the archives of the said Government.

The said Government shall immediately forward to all the other Powers a duly certified copy of the notification, as well as of the act of accession, mentioning the date on which it received the notification.

_Article 25_

The present Convention, duly ratified, shall replace, as between Contracting Powers, the Convention of July 29, 1899, for the adaptation to naval warfare of the principles of the Geneva Convention.

The Convention of 1899 remains in force as between the Powers which signed it but which do not also ratify the present Convention.

_Article 26_

The present Convention shall take effect, in the case of the Powers which were parties to the first deposit of ratifications, sixty days after the date of the Protocol recording such deposit, and, in the case of the Powers which shall ratify subsequently or which shall accede, sixty days after the notification of their ratification or of their accession has been received by the Netherland Government.

_Article 27_

In the event of one of the Contracting Powers wishing to denounce the present Convention, the denunciation shall be notified in writing to the Netherland Government, which shall immediately communicate a duly certified copy of the notification to all the other Powers, informing them of the date on which it was received.

The denunciation shall only operate in respect of the denouncing Power, and only on the expiry of one year after the notification has reached the Netherland Government.

_Article 28_

A register kept by the Netherland Ministry for Foreign Affairs shall record the date of the deposit of ratifications effected in virtue of Article 23, paragraphs 3 and 4, as well as the date on which the notifications of accession (Article 24, paragraph 2) or of denunciation (Article 27, paragraph 1) have been received.

Each Contracting Power is ent.i.tled to have access to this register and to be supplied with duly certified extracts from it.

In faith whereof the Plenipotentiaries have appended their signatures to the present Convention.

Done at The Hague, October 18, 1907, in a single original, which shall remain deposited in the archives of the Netherland Government, and of which duly certified copies shall be sent, through the diplomatic channel, to the Powers invited to the Second Peace Conference.
