The war in the air developed into a reign of terror during the second half of the first year of the world catastrophe. While the armies on the land were locked in terrific conflict, and the navies were sweeping the seas, the huge ships of the air were hovering over cities with a desperate resolve to win on all sides. By degrees the pilots of the various nations learned to work in squadrons. The tactics of the air began to be developed and opposing aerial fleets maneuvered much as did the warships. Long raids by fifty or more machines were reported, tons of bombs being released upon cities hundreds of miles from the battle line.

The German ambition to shell London was realized, and the east coast of England grew accustomed to raids. The spirit of the British never faltered. Perhaps it was best typified in the admonition of a Yarmouth minister following a disastrous Zeppelin visit, who said: "It is our privilege, we who live on the east coast, to be on the firing line, and we should steel ourselves to face the position with brave hearts."

Casualties grew in all quarters. French cities were the greatest sufferers, although French airmen performed prodigies of valor in defending the capital and in attacks upon German defensive positions. But the stealthy Zeppelin took heavy toll on many occasions. It was shown that there was no really adequate defense against sudden attack from the air. Constant watchfulness and patrolling machines might be eluded at night and death rained upon the sleeping city beneath.

The spring of 1915 found the air service of every army primed for a dash. The cold months were spent in repairing, reorganizing and extending aerial squadrons. Everything awaited the advent of good weather conditions.

During February, 1915, the hand of tragedy fell upon the German air service. Two Zeppelins and another large aircraft were wrecked within a couple of days.

In a storm over the North Sea on February 16, 1915, a Zeppelin fought heroically. Contrary air currents compelled the Zeppelin commander to maneuver over a wide zone in an effort to reach land. Caught in the gale the big dirigible was at the mercy of the elements. Snow, sleet, and fog enveloped it and added to its peril. The craft caught in the February storm, fought a losing battle for twenty-four hours and finally made a landing on Fanoe Island, in Danish territory. The officers and men were interned, several of whom were suffering from exposure in an acute form and nearly all of them with frostbitten hands and feet.

Another Zeppelin was lost in this same February storm. It is presumed that the two started on a raiding trip against England and were caught in the storm before reaching their destination. Details of the second Zeppelin's fate never have been told. It fell into the sea, where parts of the wreckage were found by Dutch fishermen. All on board lost their lives. The third airship wrecked that month was of another type than the Zeppelin. It foundered off the west coast of Jutland and four of its crew were killed. The others escaped, but the airship was a total loss.

This trio of accidents shocked the German official world to its depths and had a chilling effect upon the aerial branch of its military organization for some weeks. The Zeppelins remained at home until the return of better weather. England, for a time, was practically freed from the new menace.

It was not accident alone, nor an adverse fortune, which caused the loss of the three airships. The position of the British Isles, on the edge of the Atlantic, enabled British weather forecasters to tell with almost unfailing exactness when a storm was to be expected. The French also had an excellent service in this direction. Realizing that bad weather was the worst foe of the Zeppelin, aside from its own inherent clumsiness, the two governments agreed to suppress publication of weather reports, thereby keeping from the Germans information of a vital character. The German Government maintained a skilled weather department, but the geographical location of the country is such that its forecasters could not foretell with the same accuracy the conditions on the Atlantic. The shrewd step of the French and British therefore resulted in the destruction of three dirigibles in a single month, a much higher average than all the efforts of land guns and aviators had been able to achieve.

February, 1915, was a bleak, drear month. Aviators of all the armies made daily scouting trips, but wasted little time in attacking each other. Few raids of importance took place on any of the fronts. But British airmen descended upon German positions in Belgium on several occasions. Zeebrugge, Ostend, and Blankenberghe received their attention in a half dozen visits between February 5 and 20.
