 At about this time, Yūnagi detached from the Japanese column and reversed direction, perhaps because she lost sight of the other Japanese ships ahead of her, or perhaps she was ordered to provide a "rear guard" for Mikawa's force. One minute later, Japanese lookouts sighted a warship to port. This ship was the destroyer Jarvis, heavily damaged the day before and now departing Guadalcanal independently for repairs in Australia. Whether Jarvis sighted the Japanese ships is unknown, since her radios had been destroyed. Furutaka launched torpedoes at Jarvis, which all missed. The Japanese ships passed as close to Jarvis as 1,100 meters, close enough for officers on Tenryū to look down onto the destroyer's decks without seeing any of her crew moving about. If Jarvis was aware of the Japanese ships passing by, she did not respond in any noticeable way.
