Teetering Head
As far as I can make out the closest Zepp attack to Chrisp St was carried out by L33 on Sept 23/24 1916.
L33 commanded by Alois Bocker approached the coast along the Thames estuary and River Crouch before running in over South Brentwood and Chadwell Heath. Believing himself to be over Tower Bridge Bocker dropped 2 300kg bombs, 8 100kg bombs and 32 50kg bombs along with 20 incendiaries. These actually fell on Bromley by Bow creating a fire at an oil depot, destroying a row of tenements and a pub resulting in 12 injuries and 6 fatalities.
However,whilst over Bromley at 13,000ft Bocker's L33 took a hit from an artillery shell. This ripped the skin of the gas cell resulting in Bocker gradually losing height. Bocker made a dash for the coast but was unable to maintain height eventually coming down at Little Wigborough on Mersea Island. Bocker and his crew were subsequently caught and held as POW's.
Is that sufficiently "anoraky"?
