Once the Allies realized this they started sending in forces and by August 7 Allied forces started landing on Guadalcanal, Gavutu and Tulagi. Duncan's crew, however, thinking that Farenholt and Laffey were commencing an attack on the Japanese warships, increased speed to launch a solitary torpedo attack on Gotō's force without telling Scott what they were doing. Incorrectly applying the perceived lessons learned from this battle, U.S. commanders in future naval night battles in the Solomons consistently tried to prove that American naval gunfire was more effective than Japanese torpedo attacks. [12], To protect the transports carrying the 164th to Guadalcanal, Ghormley ordered Task Force 64 (TF 64), consisting of four cruisers (San Francisco, Boise, Salt Lake City, and Helena) and five destroyers (Farenholt, Duncan, Buchanan, McCalla, and Laffey) under U.S. Rear Admiral Norman Scott, to intercept and combat any Japanese ships approaching Guadalcanal and threatening the convoy.

Fubuki was starboard of Aoba and Hatsuyuki to port. [16], Allied reconnaissance aircraft sighted Jojima's supply convoy 210 mi (180 nmi; 340 km) from Guadalcanal between Kolombangara and Choiseul in the Slot at 14:45 on the same day, and reported it as two "cruisers" and six destroyers.

The U.S. formation at this point was in position to cross the T of the Japanese formation, giving Scott's ships a significant tactical advantage. Two screening destroyers—Fubuki and Hatsuyuki—accompanied CruDiv6. After two days into the Battle of Savo Island the crews of the Allied ships were exhausted so the ship was at Condition II.

At 07:00, five CAF Douglas SBD-3 Dauntless dive bombers attacked Kinugasa but inflicted no damage. [11], In the meantime, Major General Millard F. Harmon—commander of United States Army forces in the South Pacific—convinced Vice Admiral Robert L.

Since U.S. Navy warships had yet to attempt to interdict any Tokyo Express missions to Guadalcanal, the Japanese were not expecting any opposition from U.S. naval surface forces that night. At the Battle of Savo Island, Japan sank three American ships and killed over 1,000 U.S. sailors in addition to dooming an Australian ship and killing 84 Australian sailors while suffering 129 killed of their own.
