General Henry “Hap” Arnold was in England at Eighth AF headquarters that week. In the coming days, replacement crews arrived from the US to fill the void. Meanwhile, command and strategic changes were put into motion. By the first week of January 1944, P-51 Mustang fighters began arriving in significant numbers. Lieutenant General Jimmy Doolittle replaced Lieutenant General Eaker, who assumed command of the Mediterranean Allied Air Forces. By D-Day, Allied ground troops landed along the Normandy coast and only a handful of enemy fighters were encountered.
