Operation Türkenkreuz News of the deadliest bombing raid of WWI (and the first daylight raid over London), which occurred two days prior. Over 100 planes involved. Details from wikipedia:
"An attack on 5 June was diverted to Sheerness in Kent due to a poor weather forecast but a third raid on 13 June, taking off at 10:00 a.m., was the first daylight raid on London. As there had been little planning, early attempts to intercept the Gothas were ineffective. In England, 92 aircraft took to the air but few were able to climb high enough to engage the bombers. A Bristol F.2 Fighter of 35 (Training) Squadron flown by Captain John Cole-Hamilton with Captain C. H. C. Keevil as the observer, attacked three Gothas over Ilford but Keevil was hit by return-fire and killed instantly. British anti-aircraft guns near the coast managed to hit the aircraft of Captain T. Grant of 39 Squadron, who made a forced-landing at Rochford. As the Gothas flew on the crews could see aircraft taking off from airfields as they approached, the air peppered with smoke from anti-aircraft fire. Beyond Southend, the formation was approached by a Sopwith Triplane (114 mph (183 km/h), time to 10,000 ft (3,000 m), ten minutes) which fired at too great a distance to have an effect. Near Ostend, a British formation was spotted and one fighter made a head-on attack on a Gotha which was then attacked by a Sopwith Camel from the rear, hitting the aircraft with gunfire before the combined fire of several Gothas drove off the British fighters.
The raid caused 162 deaths and 432 injuries. Among the dead were 18 children, killed by a bomb falling on the Upper North Street School primary school in Poplar. The reason for the relatively large numbers of casualties seems to have been public ignorance as to the threat posed by aerial bombardment in daylight. Lieutenant Charles Chabot, a RFC pilot on leave, recorded that: "...Raids hadn't become a very serious thing and everybody crowded out into the street to watch. They didn't take cover or dodge". This was the deadliest air raid of the war and no Gothas were lost. News of the raid was received enthusiastically in Germany and Brandenburg was summoned to Berlin to be awarded the Pour le Mérite, Germany's highest military honour. On taking off for the return journey, his aircraft had an [sic] failure; Brandenburg was severely injured and his pilot, Oberleutnant} Freiherr von Trotha, was killed."
