Several months later on 11 March 1943, a massive fleet of 314 RAF bombers arrived at Stuttgart. Pathfinder units claimed to have spotted the city, but most of the bombs dropped that night fell in open country and on dummy Pathfinder indicators, the first use thereof by the Germans, but still 112 died and 386 were injured when Vaihingen and Kaltental were hit, resulting in the destruction of 118 houses. Six Halifaxes, three Stirlings, and two Lancasters, 3.5% of the total force, were lost during the operation. The next month, 462 bombers marshaled against Stuttgart and again the Pathfinders claimed to have accurately identified Stuttgart, but the actual bombardment occurred to the northeast of the city. This mission proved a costly failure, as eight Stirlings and Wellingtons, four Halifaxes, and three Lancasters were lost. That October, the RAF changed gears and sent a force of 343 Lancasters for a nighttime attack with the 101st Squadron equipped with the "Airborne Cigar" jamming device and supplemented with several diversionary flights, all together ensuring that only four Luftwaffe night fighters made their way to Stuttgart by the end of the raid. For a loss of only four Lancasters, the raid was a massive success, killing 104 civilians and injuring 300 more. A further 31 deaths and 156 injuries were sustained the next month on 26 November 1943, as a diversionary force of 178 bombers conducted a scattered raid on Stuttgart to draw night fighters away from Berlin for a cost of six Halifaxes lost to the Luftwaffe.
