 Once this was corrected, 80 Wing was able to jam the beam so successfully that the 50 per cent success rate (bombs on target) of the early "Baedeker" raids dropped to 13 per cent and the campaign petered out.R.V.Jones estimated that the delay in allowing 80 Wing to begin jamming cost about 400 lives and another 600 serious injuries, while Anti-Aircraft Command was forced to redeploy hundreds of guns to cover potential "Baedeker" targets.
