Fifty-one officers and two hundred and forty-one (241) enlisted men were transferred to the group on 15 February 1943. The source of the cadre was the 46th Bombardment Group and units from Will Rogers Field; Blythe AAF, California; Barksdale Field, Louisiana and a number of men with considerable overseas experience from the Third Air Force Replacement Center, Plant Park, Florida. On that date, the 46th BG moved to the North side of Will Rogers Field, leaving the South side to the 416th BG.
