Shortly after one o'clock on the morning of March 21, 1915, two Zeppelins appeared above Paris. Four of the raiders started from the German lines originally, but two were forced to turn back. They were first seen above Compiegne, north of which the German lines came nearest to Paris. The news was flashed ahead. The French airmen rose to meet them. Two of the Zeppelins eluded the patrol. Their coming was expected and when they approached the city searchlights picked them up and kept the raiders in view as they maneuvered above the French capital. The French defenders and the Zeppelin commanders met in a bold battle in the air. The Zeppelins kept up a running fight with pursuing aeroplanes while dropping bombs. They sailed across Mt. Valerien, one of the most powerful Paris forts, dropping missiles which did little harm. A searchlight from the Eiffel Tower kept them in full view. They were forced to move rapidly. Finally they swung in a big arc toward Versailles, and then turned suddenly and sailed for the heart of the city. Twenty-five bombs were dropped. Eight persons were struck and a number of fires started. The Parisians flocked to the streets and watched the strange combat with rapt interest. Although the raiders had come before, the spectacle had not lost its fascination. Even though the authorities issued strict orders and troops tried to drive the throngs indoors, Parisians persisted in risking life and limb to see the Zeppelins battle in the night skies. Upon this occasion the battle aloft lasted until after four o'clock in the morning, or more than three hours. On the same night, March 21, 1915, three bombs were thrown upon Villers-Cotterets, fifteen miles southwest of Soissons. There was small damage and no casualties. But the two raids emphasized that a few weeks more would see intensive resumption of war in the air. French aviators shelled Bazincourt, Briey, Brimont, and Vailly on March 22, 1915. At Briey, the station was damaged and the railway line cut, two of the birdmen descending to within a few hundred yards of the track. Enemy batteries at Brimont suffered damage. The next day a German machine was shot down near Colmar, in Alsace, and its two occupants captured. With the return of spring, 1915, came renewed activity among airmen on all fronts. The first day of April was marked by the loss of two German machines, one near Soissons and the other near Rheims. The first fell a victim to gunfire, both occupants being killed. The second, an Albatross model, was discovered prowling above Rheims. French pilots immediately gave chase and after a circuitous flight back and forth across the city, compelled the enemy machine to land. The pilot and observer were overpowered before they had time to set it afire, the usual procedure when captured.
