Though Zeppelins apparently had practically reached the end of their usefulness, a considerable increase took place in the number and extent of aeroplane raids, especially over England.
A number of watering places on the southeast coast of England were raided on August 12, 1917. Twenty-five persons were killed, fifty-two injured, and two German machines were brought down. Dover, Margate, and Ramsgate were visited on August 22, 1917, killing eleven persons and injuring thirteen. Eight of the attacking machines failed to return home.
The east coast was again raided on September 2, 1917. The following day, September 3, 1917, an English naval station at Chatham, near London, was bombed. One hundred and eight persons were killed and ninety-two wounded, most of them members of the English naval service. The first moonlight raid of London was carried out during the night of September 4-5, 1917. It resulted in the death of eleven persons and in the wounding of sixty-two.
Five zeppelins destroyed after the air raid on London, October 19-20, 1917.
The end of September, 1917, brought a large number of raids on England. On the 24th the southeast coast and the London district were raided. Fifteen were killed and seventy injured. Again on the 25th German machines appeared over London, killing seven and wounding twenty-six. On September 29, 1917, another raid killed eleven and wounded eighty-two; two of the attacking machines being brought down. The next night machines again were over England, killing nine persons.
One of the strongest air attacks was carried out on October 1, 1917. Four German squadrons attacked a number of coast towns, ten persons were killed and thirty-eight wounded. The next raid occurred on October 31, 1917. There were thirty German machines, but only three succeeded in reaching London. Eight persons were killed and twenty-one wounded.
Twenty-five German machines broke through the English air defenses and reached London on December 6, 1917. Two of them were brought down, not, however, until they had killed seven persons and injured twenty-one. Other raids occurred on December 18 and 21, 1917. Each time a number of the German machines were brought down. Ten persons were killed and seventy were injured.
