After these fights, Fletcher was concerned about the losses to his carrier fighter aircraft. He was also anxious about the threat to his carriers from Japanese air attacks, and worried about his ships' fuel levels. Fletcher pulled back from the Solomon Islands area with his carrier task forces the evening of 8 August. As a result of the loss of carrier-based air cover, Turner pulled back his ships from Guadalcanal, even though less than half of the supplies and heavy equipment needed by the troops ashore had been unloaded. Turner planned, however, to unload as many supplies as possible on Guadalcanal and Tulagi throughout the night of 8 August and then depart with his ships early on 9 August.
