The British system for welcoming aerial intruders started with the Chain Home and Chain Home Low radar stations. The former could detect raids at high altitude before they even left France, while Chain Home Low could spot low-level aircraft out into the middle of the Channel. Once aircraft reached England, the Observer Corps would phone in sightings, too. All of this information went to RAF Fighter Command headquarters at Bentley Priory, and also to the headquarters of various groups. Below is the map table in the operations room at RAF Uxbridge, 11 Group headquarters.
You can see the squadron boards at the top of the picture, which lit up to indicate squadron status, and the map table at the bottom. Raids were plotted using the counters without the yellow bit on a stick, with the lower number indicating the size of the raid and the upper number indicating its altitude in feet (I've also seen counters with a raid ID, assigned consecutively based on order of detection). The other counters are RAF responses, the yellow bit with the number indicating which squadron the counter represents. Curiously, the counters on the table there don't reflect the usual reality—RAF squadrons almost exclusively flew in twelves, and it was rare for the Luftwaffe to encounter paired squadrons or larger groups because of the extra time it took to form up. As one RAF officer said, every minute's delay translates to 2,000 feet the RAF interceptors wouldn't have. A squadron would reach the raid, and, per Luftwaffe doctrine, and one Staffel of escorts would peel off and dogfight the interceptors to prevent them from reaching the bombers. I wondered if that was the best way to handle things at first, but I don't know that there's a better way—the Luftwaffe has no radar coverage of Britain at all, so they don't really know how many aircraft are scrambling to meet the raid, and it would be something of a waste to meet the RAF squadrons with, say, 2-1 strength, and then find that there are another two squadrons coming to pound the bombers.
Anyway, it's the morning of July 12th, and Herr Reichsmarshall Fishbreath Göring plans to exercise the RAF's defense to its utmost.
I've planned three raids. R001 is a Stuka raid against the Ventnor Chain Home station (the raid flying due north), followed minutes after by a low-level raid by unescorted Bf 110s (the raid flying northwest). Just over half an hour later, 96 He 111s will target the Woolston Supermarine Factory (flying west-northwest). All told, there are 374 aircraft involved in these sorties. It's the biggest flight sim scenario I've ever seen.
It's difficult to describe exactly how nerve-wracking this game is. As the Luftwaffe commander, I have very little information about the RAF response to my raids before the interceptors actually show up, and while I'm flying I don't even have access to that. I'm only able to swallow hard and hope for success when I see the raid again. I'm able to put it out of my mind this time, and flying escorts for both raids, I bag two Spitfires and two Hurricanes in total.
I run out of targets and spare fuel just about simultaneously at 8:10, just after the bombers should have dropped on Woolston. It doesn't appear that they hit their target, possibly due to cloud or to navigational failures. That's quite a shame, but it's about time that my best-laid plans were ruined by weather. Everyone heads home, and at least we got the radar station pretty good.
For good measure, I launch an unescorted, lone, low-level raid of Bf 110s at the radar station as night is getting close, but it's intercepted and forced to turn back, losing a handful of planes.
Luftwaffe intelligence suggests 15 squadrons of RAF fighters met us today across all three raids. My tally for the RAF's losses comes to 61. The escorts for the Stuka raids shot down nearly two full squadrons of Hurricanes. Luftwaffe losses, on the other hand, totaled 60: 36 Bf 109s (which are the important statistic), 4 Stukas and 5 He-111s, and 15 Bf 110s. Given the ratio of Bf 109s to British front-line fighters, I'm pleased with today's outcome.
Fishbreath's personal tally: 9 kills/1 probable/1 death
This screen shows the effects of the bomber losses bug (going from the right, the numbers are total, He 111s, Ju 88s). My listed strength here in He 111s is 121, while I actually have nearly 250 ready (as other screens and mission readiness confirm). So, although this is a really handy screen, it can't be depended on for me.
In talking about it with people at the Battle of Britain 2 forum, I'm beginning to suspect it may have to do with one of my settings; I'm going to see if I can't prove that tonight. If I can, it'll also be a workaround, so I won't have to worry about it quite as much.
