Intelligence reports indicated that this attack (on 4-5 July) on St Leu succeeded in blocking all approaches to the caves and that a large quantity of earth above the caves had fallen into them. It was also known that the Germans were making tremendous efforts to repair this damage, and a similar main force of 228 Lancasters attacked again on 7th-8th July. There was fairly heavy cloud over the target at 18,000 feet so the Australians of Nos. 463 and 467 came below this height to attack and again reported good results. Enemy ground gunfire was far more evident than on the first occasion, and, although a “Mandrel” screen was in operation to confuse enemy night fighters, the Germans brought up reinforcements from the Low Countries and 31 Lancasters were shot down, a disappointingly high percentage for an attack on northern France but one which clearly showed the importance in German eyes of protecting St Leu d’Esserent. Daylight reconnaissance later showed large new craters over the entrances to the three main tunnels. Road and rail approaches had been blocked and appeared to be beyond immediate repair. In addition the river banks had been badly cratered which caused flooding. For 10 days after this second attack on St Leu the daily average of flying-bomb attacks fell from about 100 to less than 70.
