On 9 May, TF 17 altered course to the east and proceeded out of the Coral Sea via a route south of New Caledonia. Nimitz ordered Fletcher to return "Yorktown" to Pearl Harbor as soon as possible after refueling at Tongatabu. During the day, U.S. Army bombers attacked Deboyne and "Kamikawa Maru", inflicting unknown damage. In the meantime, having heard nothing from Fletcher, Crace deduced that TF17 had departed the area. At 01:00 on 10 May, hearing no further reports of Japanese ships advancing towards Port Moresby, Crace turned towards Australia and arrived at Cid Harbor, south of Townsville, on 11 May.
