After these clashes, Fletcher was concerned about the losses to his carrier fighter aircraft strength, anxious about the threat to his carriers from further Japanese air attacks, and worried about his ships' fuel levels. Fletcher withdrew from the Solomon Islands area with his carrier task forces on the evening of 8 August. As a result of the loss of carrier-based air cover, Turner decided to withdraw 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.
