On 30 May, Captain Linnarz again commanded LZ 38 on the first London raid; LZ 37 was also to be part of the raid but suffered structural damage early on and returned to Namur. Flying from Evere LZ 38 crossed the English coast near Margate at 21:42 before turning west over Southend. London police were warned of an incoming raid around 23:00; a few minutes later small incendiaries began to fall. These devices, weighing , were filled with thermite and the exterior was wrapped in tarred rope. In total some 120 bombs were dropped on a line stretching from Stoke Newington south to Stepney and then north toward Leytonstone. Seven people were killed and 35 injured; 41 fires were started, burning out seven properties and the total damage was assessed at £18,596. Aware of the problems that the Germans were experiencing in navigation, this raid caused the government to issue a D notice prohibiting the press from reporting anything about future attacks that was not mentioned in official statements: previous press reports had contained detailed information about where bombs had fallen. Fifteen defensive sorties were flown against the raiders, only one of whom managed to make visual contact with the enemy. No ground-based guns fired and no searchlights found the airship; one pilot was killed when attempting to land.
