Following a night patrol off the southern end of Savo Island, "Jarvis" returned to Lunga Point to screen the unloading transports. The warning of an impending air attack suspended these operations and the transports and their protective screen of destroyers and cruisers deployed in the body of water between Guadalcanal and Florida Island, soon to be called "Ironbottom Sound". When enemy torpedo bombers appeared around noon on 8 August, they met a stream of antiaircraft fire. Only 9 of the 26 planes penetrated the defensive fire, but they set the attack transport ablaze and torpedoed "Jarvis".
