On the evening of 31 May 1915 Linnarz made his fifth raid on England in LZ 38. Relenting in the face of increasing pressure, the Kaiser had finally given approval for air raids on London – although at this stage they were limited to a line east of the Tower of London.

Linnarz followed his now familiar route over Southend and, adhering to the Kaiser’s restriction with impressive accuracy, appeared over Stoke Newington in north London around 11.00pm. Here, Linnarz dropped his first bomb, an incendiary, on 16 Alkham Road. Heading south, LZ 38 continued to drop bombs, with the first fatalities occurring at 33 Cowper Road, Stoke Newington. An incendiary set the house on fire and claimed the life of 3-year-old Elsie Leggatt and fatally injured her 11-year-old sister, Elizabeth May. Moments later another incendiary set fire to 187 Balls Pond Road, burning to death a married couple, Henry and Caroline Good. Over Shoreditch LZ 38 steered away from the Tower of London, and, over Whitechapel an explosive bomb claimed two more lives in Christian Street: 8-year-old Samuel Reuben and 16-year-old Leah Lehrman, who died in hospital two days later from her injuries. The seventh and final victim of the raid, Eleanor Willis, 67, also died two days later, as a result of shock caused by the raid.

From Whitechapel LZ 38 continued to bomb, attacking Stepney before flying over Bow and dropping a single incendiary on Stratford, then releasing its final five bombs on Leytonstone. In total LZ 38 dropped 91 incendiary, 28 explosive bombs and two grenades. The defences, however, were caught out by this first London raid. LZ 38 escaped detection by any searchlights, while no anti-aircraft guns opened fire as it passed over the capital. The only ground opposition came from machine gun fire at Burnham and an AA-gun at Southminster, both in Essex. The RNAS flew 15 defence sorties but only one pilot saw LZ 38, engine problems forcing him to abandon the chase.

The home defence aircraft suffered their first loss when Sopwith Gunbus 802 flying from Hendon crashed while trying to land, killing the pilot, Flight-Lieutenant Douglas Barnes
Casualties: 7 killed, 35 injured

Damage: £18,596

The third deaths: Christian Street, Whitechapel (2 killed, 11 injured)
One of several streets leading south off Commercial Road, Christian Street would have been lined by slums and small factories and warehouses devoted to the clothing trade. It's a sign of how overcrowded these were that two bombs hitting the same spot were able to injure so many, as well as killing 8-year-old Samuel Reuben and 16-year-old Leah Lehrman. Today the only vaguely old buildings hereabouts are at the Commercial Road end of the street, below which a typical Tower Hamlets residential zone kicks in with late 20th century flats and highrises

Leah Lehrman was just 16 when she was killed while cycling from her East End home to central London and her job as a tailor. Now, 100 years after her death in one of the first Zeppelin raids of the First World War, her tomb has a memorial plaque after a 20-year search by her niece, Janet Foster, for the resting place of the aunt she never knew.

The stone setting was taking place on Wednesday June 3, exactly 100 years after her burial in an unmarked grave at Plashet Cemetery in east London, with a small family service commemorating her life.
Mrs Foster was inspired to search for the grave by her late father, who had talked to her about his sister, killed when he was just five years old.
Mrs Foster, a Jewish Care volunteer, told the Jewish Chronicle: "I'm so pleased I finally found it. I know my father would be really pleased. I did it for him. He was a child when she died, but he always used to say how beautiful she was. It means everything to find it."
