They were joined on 22 August by the U.S. Army's 67th Pursuit Squadron under Major Dale Brannon, with five Army P-400s (an "export" version of the P-39); and on 24 August by 11 SBD dive bombers that came from the aircraft carrier USS "Enterprise" because they were unable to land on their own carrier, damaged in the Battle of the Eastern Solomons. At the end of August, these warplanes were joined by 19 more Wildcats from VMF-224 under Major Robert E. Galer, and a dozen more SBD dive bombers from VMSB-231, also part of the Marine Air Group 23. This varied assortment of Army, Marine, and Navy pilots and warplanes was the beginnings of the Cactus Air Force.
