On 28–29 July the first raid to include one of the new R-class Zeppelins, L 31, took place. These were long, with a capacity of , powered by six engines and capable of operating at , and could carry up to four tons of bombs. The 10-Zeppelin raid achieved very little; four turned back early and the rest wandered over a fog-shrouded landscape before giving up. Adverse weather dispersed two raids on 30–31 July and 2–3 August. On 8–9 August, two Zeppelins were part of a nine airship raid on Hull. The sixth successful London raid was on 24–25 August when 13 Navy Zeppelins were launched and Heinrich Mathy's L 31 reached London; flying above low clouds, 36 bombs were dropped in 10 minutes on West Ferry Road, Deptford Dry Dock, the station at Norway Street and homes in Greenwich, Eltham and Plumstead. Nine people were killed, 40 injured and £130,203 of damage was caused. L 31 suffered no damage in the attack but several weeks of repair work were needed following a hard landing.
