await pickup by the reinforcement group's destroyers. All six Zeros ditched; only one pilot was recovered. Allied reconnaissance aircraft from Guadalcanal sighted Jojima's supply convoy between Kolombangara and Choiseul in the Slot at 14:45 on the same day, and reported it as two "cruisers" and six destroyers. Gotō's force—following the convoy—was not sighted. In response to the sighting of Jojima's force, at 16:07 Scott turned toward Guadalcanal for an interception. Scott crafted a simple battle plan for the expected engagement. His ships would steam in column with his destroyers at the front and rear of his cruiser column, searching across a 300 degree arc with SG surface radar in an effort to gain positional advantage on the approaching enemy force. The destroyers were to illuminate any targets with searchlights and discharge torpedoes while the cruisers were to open fire at any available targets without awaiting orders. The cruiser's float aircraft, launched in advance, were to find and illuminate the Japanese warships with flares. Although Helena and Boise carried the new, greatly improved SG radar, Scott chose San Francisco as his flagship. At 22:00, as Scott's ships neared Cape Hunter at the northwest end of Guadalcanal, three of Scott's cruisers launched floatplanes. One crashed on takeoff, but the other two patrolled over Savo Island, Guadalcanal, and Ironbottom Sound. As the floatplanes were launched, Jojima's force was just passing around the mountainous northwestern shoulder of Guadalcanal, and neither force sighted each other. At 22:20, Jojima radioed Gotō and told him no U.S. ships were in the vicinity. Although Jojima's force later heard Scott's floatplanes overhead while unloading along the north shore of Guadalcanal, they failed to report this to Gotō. At 22:33, just after passing Cape Esperance, Scott's ships assumed battle formation. The column was led by Farenholt, Duncan, and Laffey, and followed by San Francisco, Boise, Salt Lake City, and Helena. Buchanan and McCalla brought up the rear. The distance between each ship ranged from . Visibility was poor because the moon had already set, leaving no ambient light and no visible sea horizon. Gotō's force passed through several rain squalls as they approached Guadalcanal at . Gotō's flagship Aoba led the Japanese cruisers in column, followed by Furutaka and Kinugasa. Fubuki was starboard of Aoba and Hatsuyuki to port. At 23:30, Gotō's ships emerged from the last rain squall and began appearing on the radar scopes of Helena and Salt
