On the 14 August, Sperrle began a smaller, prolonged, but widely scattered series of attacks on aerodromes and other targets in the western half of England. The attacks were not very effective and earned the "Luftflotte" a rebuke from Göring. The following day, between midnight and midnight, the "Luftwaffe" made 1,786 sorties. Conferring with his commanders, Göring condemned the lack of foresight which had sent many bombers of "Luftflotte" 3 on difficult missions suitable only for experienced picked crews. The "Reichsmarshall" also deplored the waste of effort caused by choosing targets of no strategic value as 'alternatives' for crews unable to reach their primary objectives. The 15 August became known as "Black Thursday" in the "Luftwaffe" due to the scale of the fighting and losses.
