 Starting from early September, four Maurice Farman seaplanes on board the "Wakamiya" conducted reconnaissance and aerial bombing operations over Tsingtao.The aircraft had crude bombsights and carried six to ten bombs that had been converted from artillery shells and were released through metal tubes on each side of the cockpit.On September 5, in the first successful operation, two Farman seaplanes dropped several bombs on the Bismarck battery which were the main German fortifications in Tsingtao.
