P-38 ace Rex Barber flew the P-38 Lightning in the 339th Fighter Squadron, 347th Fighter Group. On April 7, 1943, Barber engaged several Mistubishi Zeros which had appeared near his airfield, Fighter Two, on Guadalacanal.
Near Cape Esperance, Guadalcanal, Barber downed two of the Zeros, his second and third victories. He went on to score two more confirmed and three probables by the end of his tour. One of the last two was on April 18, 1943, when Barber and his squadron flew a long over-water interception of Admiral Yamamoto's flight over Bougainville Island, shooting down the Admiral's bomber and killing him.
