a patrol station soon thereafter. Unfortunately, at 18:30 that afternoon, Aramis rammed (Coast Torpedo Vessel No. 12), causing the latter to miss the sailing of a convoy, but suffered no damage herself. While returning to her section base at 15:55 the next day, Aramis forward lookout spotted what looked like a floating spar about 300 yards off the starboard bow. Ensign George Dumars, USNRF, the officer of the deck, managed to obtain a quick glimpse of it before it vanished. Aramis was brought dead in the water and her listening gear was put into operation. The man listening reported that he heard submarine engines. Within five minutes, the commanding officer, Ensign Leroy W. Tilt, USNRF, called all hands to general quarters. Reporting the presence of a submarine to district headquarters, Aramis bent on speed and came about. At 17:15, the patrol craft spotted the , standing up from the eastward, about seven miles south. After her attempts to reach that vessel by radio failed, Aramis fired a blank charge to attract Hauolis attention, and the patrol boat came alongside at 18:00. Unfortunately, Hauolis approach "gummed the listening device to such an extent as to drown all other sounds," enabling the submarine—as everyone believed it was—to slip away. Aramis, with Hauoli standing by, then headed for the spot the submarine had last been seen and, during the next quarter-hour dropped her four Mark I depth charges, one by one. Unfortunately, none of them worked. Subsequently, shifting from Base No. 6 to the Marine Basin at Brooklyn—where she took on board a pair of depth charges from (Coast Torpedo Boat No. 31)—Aramis relieved the converted yacht on patrol duty on 18 August before returning to the Marine Basin for the installation of new wireless equipment. She proceeded to her section base on the 25th, only to move over to Shewan's shipyard on the 27th. Flagship No logs exist for Aramis activities over the next four months, but extant message traffic reveals that she was detached from the 3rd Naval District on 18 September for use as a division commander's flagship and was directed to proceed to Base Two (Yorktown, Virginia) and report to the Commander-in-Chief, Atlantic Fleet. However, Aramis chronic engine trouble delayed her departure until 6 October 1918, when the yacht finally sailed unescorted. What followed for the next month and a half—during which the armistice brought World War I to
