LONDON'S WELCOME TO A ZEPPELIN RAIDER
In the early part of the war Zeppelin raids on England were frequent.
The rapid perfecting of searchlights, anti-aircraft guns and airplane
defenses soon discouraged them. This picture shows an airplane about
to attack with flaming bullets.

It is probable that one of the motives of these raids was to keep at home fleets of English airplanes which might be more useful on the front. Indeed, many Englishmen, alarmed by the damage, urged such a policy, but the good sense of the English leaders prevented such a mistake from being made. Pitiful as must have been the suffering in individual cases, the whole of the damage caused by the German frightfulness was but a trifle as compared with the usefulness of the English air-fleets when directly sent against the German armies. Nevertheless, every squadron of German airplanes sent to England was attacked by British aviators, and in those attacks the Germans suffered many losses.

The worst raid of all those made was one on June 13th, which was directed upon the city of London. On that occasion ninety-seven persons were killed and four hundred and thirty-seven wounded. These airplane operations differed from the Zeppelin expeditions in being carried on in the daytime, and this raid took place while the schools were in session and large numbers of people were in the street. Only one of the attacking airplanes was brought down. The raiding machines were of a new type, about three times the size of the ordinary machine, and there were twenty-two such machines in the squadron. The battle in the air was a striking spectacle and in spite of the danger was watched by millions of the population. The raiders were easily seen and their flight seemed like a flight of swallows as they dived and swerved through the air.

The raids on England were not the only raids conducted by the Germans during the war. Paris suffered, but as soon as the warning sounded, the sky over the city was alive with defense airplanes. An attack on the French capital took place on the 27th of July and began about midnight. The German airmen, however, never got further than a suburban section of the city, and their bombardment caused but little damage. In one of the suburbs, however, a German flyer dropped four bombs on a Red Cross Hospital, killing two doctors, a chemist and a male nurse, and injuring a number of patients. The raider was flying low and the distinguishing marks of the hospital were plainly apparent.

Almost every day during the bitter fighting of 1918, reports came in that Allied hospitals had been bombed by German raiders. Attacks on hospitals were, of course, strictly forbidden by the Hague Convention, and they caused bitter indignation. Such attacks were of a piece with those upon hospital ships which were made from time to time. From the very beginning of the war the Germans could not understand the psychology of the people of the Allied countries. They were not fighting with slaves, ready to cower under the lash, but with free people, ready to fight for liberty and roused to fury by lawlessness.
