On 17 August 1943 the USAAF carried out the Schweinfurt–Regensburg mission. The ball bearing industry was damaged but the "Luftwaffe" appeared to win a defensive victory. Nevertheless, Göring made an abusive phone call to Jeschonnek that afternoon. General Meister recalled they also spoke about the coordination of night fighters and anti-aircraft artillery. During the day, Meister, as usual, went out with Jeschonnek on a skiff on Goldap lake. Afterwards, they drank champagne to celebrate Jeschonnek's daughter's birthday before parting company.
