 assigned to the cell. RAF bombers flying into Germany or France would have to cross the line at some point, and the radar would direct a searchlight to illuminate the plane. Once this had happened other manually-controlled searchlights would also pick up the plane, and the night fighter would be directed to intercept of the now-lit bomber.

s, with a range of about 30 km. Unlike the early-warning Freya radar, Würzburgs were accurate (and complex) tracking radars. One would be locked onto the night fighter as soon as it entered the cell. After the Freya picked up a target the second Würzburg would lock onto it, thereby allowing controllers in the Himmelbett center to get continual readings on the positions of both planes, controlling them to a visual interception. To aid in this, a number of the night fighters were fitted with a short-range infrared

 device known as Spanner, but these proved almost useless in practice.

Another tactic that proved effective was to send their own planes to England while the raids were taking off or landing. Radio operators listening to the RAF bomber frequencies were able to recognize the start of a raid, and the raiding force of about 30 night fighters would be sent over the RAF airbases to shoot down the bombers as they took off or landed. By the beginning of October the night intruder force had claimed a hundred kills but on October 13 Hitler ordered the force sent to the Mediterranean despite their success.

 sent in their planes one at a time in order to force the defenses to be spread as far apart as possible, meaning that any one aircraft would have to deal with little concentrated flak. However this also meant the Himmelbett centers were only dealing with perhaps one or two planes at a time, making their job much easier. At the urging of R.V. Jones

, Bomber Command reorganized their attacks against a single target at a time, sending all of the bombers in a single "stream", carefully positioned to fly right down the middle of a cell. Now the Himmelbett centers were facing hundreds of bombers, countering with only a few planes of their own. So successful was this tactic that the success rate of the night fighters dropped almost to zero.

Kammhuber started looking for solutions, and the result was the two-prong concept of Wilde Sau

In the former, day fighters would be sent up and look for the bombers from the light of flares dropped from light bombers, searchlights set to a wide beam or illuminating lower clouds, or the fires on the ground below.

 bombers lost that raid.

Zahme Sau envisioned freeing the night fighters (now equipped with radar for the final stages of the interception) from the Himmelbett cells and allowing them to attack on their own. This was not all that easy, given the current generation of radars, but newer systems being developed would greatly increase the detection range and angles. In this role the existing cells created as part of the original Kammhuber Line would be used primarily for early warning and vectoring the planes to the stream.

At the same time Kammhuber continued to press for a new dedicated nightfighter design, eventually selecting the Heinkel He 219

After the reorganization of the Luftwaffe in Scandinavia and the dissolution of Luftflotte 5, he became commanding general of the Luftwaffe in Norway (September-October 1944). In 1945 he was re-appointed to command of the night fighters, at this point a largely ceremonial position considering the state of the Third Reich at that time.

Postwar

After the fall of the Reich in May 1945, Kammhuber was held by the United States, but he was released in April 1948 without charges being brought against him. He wrote a series of monographs for the U.S. Department of Defense on the conduct of the German defences against the RAF and USAAF
