6. In the event of the Canadian or Australian Government desiring to send ships to a foreign port, they will obtain the concurrence of the Imperial Government, in order that the necessary arrangements with the Foreign Office may be made, as in the case of ships of the British Fleet, in such time and manner as is usual between the British Admiralty and the Foreign Office. 7. While ships of the Dominions are at a foreign port a report of their proceedings will be forwarded by the officer in command to the Commander-in-Chief on the station or to the British Admiralty. The officer in command of a Dominion ship so long as he remains in the foreign port will obey any instructions he may receive from the Government of the United Kingdom as to the conduct of any international matters that may arise, the Dominion Government being informed. 8. The commanding officer of a Dominion ship having to put into a foreign port without previous arrangement on account of stress of weather, damage, or any unforeseen emergency, will report his arrival and reason for calling to the Commander-in-Chief of the station or to the Admiralty, and will obey, so long as he remains in the foreign port, any instructions he may receive from the Government of the United Kingdom as to his relations with the authorities, the Dominion Government being informed. 9. When a ship of the British Admiralty meets a ship of the Dominions, the senior officer will have the right to command in matters of ceremony or international intercourse, or where united action is agreed upon, but will have no power to direct the movements of ships of the other service unless the ships are ordered to co-operate by mutual arrangement. 10. In foreign ports the senior officer will take command, but not so as to interfere with the orders that the junior may have received from his Government. 11. When a court-martial has to be ordered by a Dominion and a sufficient number of officers are not available in the Dominion service at the time, the British Admiralty, if requested, will make the necessary arrangements to enable a court to be formed. Provision will be made by order of his Majesty in Council and by the Dominion Governments respectively to define the conditions under which officers of the different services are to sit on joint courts-martial. 12. The British Admiralty undertakes to lend to the Dominions during the period of development of their services, under conditions to be agreed upon, such flag officers and other officers and men as may be needed. In their selection preference will be given to officers and men coming from, or connected with, the Dominions, but they should all be volunteers for the service. 13. The service of officers of the British Fleet in the Dominion naval forces or of officers of those forces in the British Fleet will count in all respects for promotion, pay, retirement, etc., as service in their respective forces.
