official courtesies

The interchange of official compliments and visits between foreign military or naval officers and the authorities of a military post are international in character. In all cases it is the duty of the commandant of a military post, without regard to his rank, to send a suitable officer to offer civilities and assistance to a vessel of war (foreign or otherwise) recently arrived. After such offer it is the duty of the commanding officer of the vessel to send a suitable officer to acknowledge such civilities, and request that a time be specified for his reception by the commanding officer of the post. The commanding officer of the post, after the usual offer of civilities, is always to receive the first visit without regard to rank. The return visit by the commanding officer of the military post is made the following day, or as soon thereafter as practicable.
