III./KG 100 used the Fritz-X for the first time on 21 July against ships in Augusta harbour. The Foggia element withdrew to Istres on 27 July. It bombed ships in Palermo harbour on 1 August and again off Syracuse nine days later. By 20 August 1943 only five of the 30 Do 217s were operational. On 29 August it claimed a British cruiser damaged off Gibraltar. II./KG 100 flew the first PGM ordnance attack in history, using the rocket-boosted Henschel Hs 293 ASM (guided by the same "Kehl-Straßurg" system as the Fritz X used) off the northern tip of Spain on 25 August and damaged "HMS "Bideford". Two days later, they sank the sloop "Egret"—sunk by ""Geschwaderkommodore" Auffhammer (who took command on 4 May 1943) and "Oberleutnant" Paulus—and damaged four escorts. On 9 September 1943 both groups attack the Salerno beachhead. On 13 September it sank the hospital ship "Newfoundland". The same afternoon, 11 Do 217s of III./KG 100, led by commanding officer Bernhard Jope, sank the battleship "Roma" and damaged "Italia". From 10 to 19 September it attacked several freighters. On 16 September the group severely damaged the battleship "Warspite" and damaged "Valiant".
