Down in the underground control rooms at both Uxbridge and Stanmore the days activity started earlier than on some other days when enemy formations were detected over Cap Gris Nez at eight thirty in the morning. The RDF stations were soon reporting one hundred plus aircraft in the raid. As it approached Dover the raid split and headed for two separate targets, one was the fighter airfield at Rochford and the other was the Maritime Command airfield at Eastchurch. Four fighter squadrons were scrambled by Eleven Group to intercept these raids. It was only as the two raids were sighted by the fighters that it became apparent that with just ten bombers heading for Eastchurch and twenty seven heading for Rochford that the bulk of the raid consisted of the Me 109s. Fighting at odds the four fighter squadrons were unable to get past the defending Me 109’s and the bombers managed to hit both targets. At East Church Maritime Command lost two De Haviland Flamingo Maritime Patrol Aircraft on the ground to bomb damage and once again the airfield was cratered but remained operational. Even as the last remains of this raid retreated off the edge of the plot table another raid was forming over Calais.
Once again the target was the airfield at Rochford near Southend. Thirteen squadrons were scrambled to counter this attack. The observer corps had reported the formation was again composed of more fighters than bombers. Despite the commitment of so many aircraft by Fighter Command comparably few fighters broke through the escort to get to the bombers. Over thirty bombs hit the airfield but once again no serious damage was done and the airfield though battered remained open.
The next attack was in the form of large fighter sweeps coming in over Kent and the Thames Estuary. Here there was a breakdown in communication and Parks instruction that combat with enemy fighter formations was to be avoided was not followed and all the seven squadron sent to counter the attack suffered casualties. That brought the days confrontations to an end with the RAF losses of twenty fighters only being two less than the Luftwaffe losses of Me 109’s. This loss ratio was improved by the fourteen enemy bombers that failed to return safely to their bases.
The night saw the first concerted large scale attack on the docks at Liverpool. Some one hundred and fifty bomber aircraft were involved in this attack, whilst diversionary attacks, often of only a single bomber were made against Birmingham, Sheffield, London, Coventry, Manchester and Derby. No 80 wing aircraft flying that evening had detected the German navigation beams but this could only give the axis of the attack as they crossed several potential targets. However it did enable the Night Fighter force to concentrate on the track of the main raid. No less than twelve of the GCI/PPI stations were able to direct fighters into the main attack.
Here the Fighter Command plot table at Bentley Priory became vital in coordinating the various sorties so that the RAF Night Fighters did not clash with their own. At one time so many night fighters were in the area covered by the PPI station at Rack Green that the IFF signals almost blanked out the screens. This was due to aircraft under the control of the neighbouring PPI sites at Trewan Sands, St Annes and Conberton also being in the area covered by Rack Green. Whilst this situation lasted a very short period it raised some very important questions for the Operational research teams. Slightly earlier the four Coastal GCI/PPI stations between Bournemouth and Dover had ceased directing individual night fighters but had instructed them use their RDF 1.5 sets to get close enough to the bomber stream for their RDF.2 sets to get a return. The four coastal stations giving a running commentary to the fighters on their frequencies as to the height location and speed of the main enemy formations. The afteraction analysis of this approach to countering mass night attacks would go a long way to formulating fighter commands response to a large scale night assault. Despite this being the largest night fighter effort to date Liverpool and Birkenhead were badly bombed. With the increased number of GCI/PPI stations now operational the air raid warning system run from Fighter Command HQ was no longer so dependant on the Observer Corps for tracking raids. air raid warnings were issued to indicate three levels of threat from Yellow as a preliminary, Purple, raid approaching douse all working lights etc. Red, Sound Sirens. The Issuing of Purple alerts was very disrupting to the works of docks and marshalling yards that really did require task lighting. So getting the threat level right and issuing timely warning was an important task, now made easier by the almost real time tracking of the bombing raids across the country achieved by the GCI/PPI network.

August the 29th
Day; Quiet morning. Airfield attacks in south and south-east in afternoon.
Night; Liverpool again attacked; diversions in the midlands.
Weather; showers and bright interval. Channel and Straits cloudy. (1)
The lack of air activity in the morning was a welcome respite after such a busy and frenzied night. At mid-afternoon as the day brightened Luftflotte Two put up three large fighter sweeps, starting to cross the channel from Cape Gris Ness, Boulogne and the mouth of the Somme. The response to these large formations was again the scrambling of thirteen squadrons from Eleven Group. However to day the Squadrons largely obeyed the instructions issued by Parks on the 19th of August that combat should not be engaged solely with fighter formations. The sense of this instruction becomes apparent when later the Luftwaffe records became available it was shown that these sweeps comprised some five hundred and sixty four Me 109’s with an additional one hundred and fifty nine Me 110’s also taking part, this was some what greater that the RAF estimates of four hundred and fifty given on the day. The RAF figure meant that the thirteen squadrons from Eleven Group were facing more than twice their number whilst in reality the odds were actually over three to one. This refusal to engage large enemy fighter formations was in some quarters seen as yielding air superiority to the enemy.
With the coming of the night Luftflotte Three carried out their second consecutive night of major raids on Liverpool with some one hundred and thirty aircraft bombing the docks and city. The night fighter response was much the same as the previous night but with concerted efforts not to swamp any single GCI/PPI station. Once more the coastal stations used the passive RDF 1.5 sets on the night fighters to try and intercept the raids as they approached the coast. Tonight the stations at Salcombe, Exminster and Sturminster Newton to the west of Bournemouth also employed this tactic.
The restraint showed by Eleven Group in countering the large enemy fight formations was reflected in the losses for the day. Whilst the RAF losses were restricted to nine aircraft with only three pilots killed the Luftwaffe lost twenty seven aircraft most of which were Me 109’s and 110’s.
