The Schütte-Lanz SL 11 was a German military dirigible built in 1916 by Luftschiffbau Schütte-Lanz. It was the first German airship to be shot down while bombing England.
The SL 11 was based at Spich and commanded by Hauptmann Wilhelm Schramm. In the early hours of 3 September 1916, after jettisoning bombs over Essendon, Hertfordshire, destroying several houses, damaging a church, and killing two sisters aged 26 and 12, it was then shot down over nearby Cuffley by Lt. William Leefe Robinson flying a BE 2C using incendiary ammunition. It crashed at Cuffley, killing the entire crew, who were buried at Potters Bar Cemetery; they were re-interred at Cannock Chase German Military Cemetery in 1962. Robinson was awarded the Victoria Cross.
