On the German side, there was a call to unify German fighter forces and hold them back from coastal and keep them out of Allied fighter escort range. Regardless of the logic, Sperrle opposed the idea to preserve his command. Sperrle was sensitive to a centralise command for fighter forces and resisted. On 14 September 1943, "Luftflotte" 3 area of operations covered most of France, with the exception of some regions in Alsace-Lorraine; Luxembourg, western and southern Belgium were his responsibility. Sperrle's headquarters remained in Paris. The largest organisation attached to Sperrle's command was 3. "Jagd" Division (3rd Fighter Division) based at Metz, under the control of Werner Junck. Sperrle had retained the "Luftgau" in southern Germany, and his air fleet was given control of the 5. "Jagd" Division. On 15 September 1943 an effort to improve Sperrle's organisation was made by creating II. "Jagdkorps" with the 5th and 4. "Jagd" Division. The improvement in command and control made little difference in the battle with the USAAF for neither division received the reinforcements it needed.
