Patch, afraid of another Japanese attack, sent only a small portion of his troops to continue an attack against Hyakutake's forces. On 29 January, Halsey sent a resupply convoy to Guadalcanal protected by a cruiser task force. Sighting the cruiser task force, Japanese naval torpedo bombers attacked the task force and heavily damaged the U.S. cruiser . The next day, more torpedo aircraft attacked and sank "Chicago".
