The British Operation Corona helped confuse the defences and Göring's mishandling of the night fighter force allowed Bomber Command to devastate Kassel. Göring deflected the blame for British attacks on his subordinates and his relations with them deteriorated.[25][26] In August 1943 Jeschonnek killed himself after the failed defence of Peenemünde. In November 1943 Bomber Command began the Berlin campaign and Kammhuber was dismissed from command.[27]
