The German fighters, taking advantage of the illumination from searchlights, target indicator flares and fires claimed that they shot down 12 aircraft, but had to share their claims with the anti-aircraft batteries who also claimed the downings. To avoid friendly fire losses, anti-aircraft batteries restricted the height of their flak and the fighters operated above that pre-agreed ceiling. |
