Governing the Conduct of American Merchant
Vessels on which ARMED GUARDS have been placed.
1. Armed Guards on Amierican merchant vessels are for
the sole purpose of defense against the unlawful acts of the submarines of Germany or of any nation following the policy announced by Germany in her note of January 31, 1917. Neither the Armed Guards nor their arms can be used for any other purpose.
2. The announced policy of Germany, in her note of January 31, 1917, to sink all vessels that enter certain areas of the high seas, has led the Government of the United States to authorize Armed Guards on merchant vessels to resist any and all attempts of the submarines of Germany or of any nation following the policy announced by Germany in her note of January 31st, to put that policy into practice.
3. It shall be lawful for the Armed Guard on any American merchant vessel to fire upon any submarine of Germany or of any nation following the policy of Germany announced in her note of January 31, 1917, that attempts to approach, or lies within 4,000 yards of the commercial route of the vessel sighting the submarine, if the submarine is sighted within the zone proscribed by Germany.
4. No Armed Guard on any American merchant vessel shall fire at any submarine that lies more than 4,000 yards from the commercial route of the vessel sighting the submarine, except that the submarine shall have fired first.
5. No Armed Guard on any American merchant vessel shall take any offensive action against any submarine of Germany or of any nation following the policy of Germany announced in her note of January 31, 1917, on the high seas outside of the zones proscribed by Germany, unless the submarine is guilty of an unlawful act that jeopardizes the vessel, her passengers, or crew, or unless the submarine is submerged.
6. No Armed Guard on an American merchant vessel shall attack a submarine that is retiring or attempting to retire either within or without the zone proscribed by Germany, unless it may be reasonablly presumed to be manouevering for renewal of attack.
7. In all cases not herein specifically excepted the Armed Guard on American merchant vessels shall be governed by the principles of established international law and the treaties and conventions to which the Government of the United States is a party.
8. American merchant vessels are forbidden to pursue or search out the submarines of any nation or to engage in any aggressive warfare against them.
9. American merchant vessels shall make every effort compatible with the safety of the merchant vessel to save the lives of the crew of any submarine that may be sunk, or that submits, or is in distress.
<*> 10. American merchant vessels shall make every effort to avoid the submarines of Germany and of any nation following the policy of Germany announced in her note of January 31, 1917, while in the zones proscribed by Germany.
<*> 11. American merchant vessels shall display the American colors continuously at sea.
12. American merchant vessels should communicate with the Commandant of the Naval District before leaving a United States port to make sure of the latest information.
13. The safety of American merchant vessels requires that they obey all instructions of vessels of war of the United States.
ON SIGHTING A SUBMARINE IN
THE PROSCRIBED ZONES
14. If a submarine is sighted beyond torpedo range, bring submarine abaft the beam and keep her there. If submarine attempts to close, bring her astern and proceed at highest possible speed.
15. If submarine is sighted close aboard forward of the beam, the greatest safety lies in changing course directly toward the submarine.
16. If submarine is sighted close aboard abaft the beam, the greatest safety lies in turning away from the submarine and proceeding at highest speed.
ON OPENING FIRE IN DEFENSE
AGAINST THE UNLAWFUL ACTS OF SUBMARINES
17. Hoist national colors before first shot is fired.
18. Once it has been decided to open fire, do not submit to the gun fire of a submarine so long as the armed guard can continue to fire.
19. Send all persons except bridge force and the armed guard below decks while vessel is under fire.
20. Watch out for torpedoes and maneuver to avoid them. If unable to avoid them, maneuver so that they will strike a glancing blow.
