On the night of June 4, 1915, German dirigibles attacked towns at the mouth of the Humber, the port and shipping of Hardwich, in England. There were some casualties and considerable property loss, but the British Government would not make public the extent of the damage as the places attacked were of naval importance. Calais, on the French coast was raided the next day by two German airmen. There was one casualty. England's east coast was visited by Zeppelins on the night of June 6, 1915, twenty-four persons being killed and forty hurt. There was much damage, all details of which were suppressed. Just after the break of day on June 7, 1915, a British monoplane was returning from a scouting trip over Belgium. At the same hour a Zeppelin flew homeward from the English coast. The two met between Ghent and Brussels. Four persons had been killed and forty injured during the night at Yarmouth and other near-by towns on the East channel coast. Raids had been frequent of late and the British pilot sensed the fact that this Zeppelin was one of the dreaded visitors. He was several miles away when the big aircraft hove into view. Uncertain for a few minutes how to proceed, he rose until he was two thousand feet above the Zeppelin. His maneuver was not appreciated at first, or the Zeppelin crew did not see him. There was no attempt either to flee or give battle. But as the monoplane drew nearer it was sighted and a combat followed such as never was seen before. Sub-Lieutenant R. A. J. Warneford, a young Canadian who had not reached twenty-one years of age, matched his pygmy machine against the great aerial dreadnought. The fight started at a height of 6,000 feet. Lieutenant Warneford released his first bomb when about 1,000 feet above the Zeppelin. He saw it strike the airbag and disappear, followed by a puff of smoke. Because of the sectional arrangement this did not disable the airship. The Lieutenant circled off and again approached the Zeppelin. Every gun was trained upon him that could be brought to bear. The wings of his machine were shattered many times, but he kept on fighting. When once more above the enemy craft, he released another bomb. It also struck the Zeppelin, but appeared to glance off. The antagonists resorted to every conceivable ruse, one to escape, the other to bring down its quarry. All efforts of the Zeppelin commander to reach the height of his antagonist were defeated. His lone enemy kept above him. The battle varied from an altitude of 6,000 to 10,000 feet. Three other bombs struck the airship, and each time there was the telltale wisp of smoke.
