When the time came for them to go to the front, the Fates still favoured them; they went out together to the same regiment in France, and were drafted to the same company. Together they went up to the trenches for the first time, together they worked, together they crouched under the parapet when the German shells came unpleasantly close, and, all the time, Jonathan, calm and stolid, unconsciously helped the other, who, being cursed with a vivid imagination, secretly envied his friend's calm. Now, nothing has more power to cement or break friendships than war. The enforced company, the sharing of danger, the common bearing of all imaginable discomforts combine to make comrades or enemies. There are so many things to tax one's patience, that a real friend in whom one may confide becomes doubly dear, while you end by hating a man who has the misfortune to irritate you day after day. War made David and Jonathan realise how much their friendship meant, and how necessary each was to the other, the one because of his continued calm, the other because of the relief his love of music and of Nature brought with it. II Near the end of April 1915 they came back to billets near Ypres. To the north a terrific battle was in progress, the last inhabitants were fleeing from the town, and huge shells screamed on their way, and burst with appalling clouds of smoke among the already shattered houses. Occasionally a motor cyclist would come racing down the road, and, once or twice, an ambulance came by with its load of gassed and wounded from the fighting to the north. One morning, when the Germans seemed fairly quiet, David and Jonathan set out arm in arm towards Ypres, to explore. An occasional shell--a hum, increasing until it became a roar, followed, a moment after, by a fearful explosion--warned them not to proceed beyond the outskirts of the town, and here it was that they came upon a large villa, with lilac budding in the garden. By mutual consent, they turned in at the tall iron gate, and entered the half-ruined house. The part of the house giving on the road had been destroyed by a large shell. Over a gaping hole in the ceiling was a bed, its iron legs weirdly twisted, which threatened to overbalance at any minute and to come hurtling down into the hall beneath. Shattered picture frames still hung on the walls, and on the floor near at hand lay a rosary, the Crucifix crushed by some heedless boot. The furniture lay in heaps, and the front door was lying grotesquely across a broken mirror. Everywhere was wreckage. The other half of the house was still almost intact. In what had once been the salon they found comfortable chairs and an excellent Pleyel piano, while a copy of the _Daily Mirror_ gave the clue that the room had until recently been occupied by British troops.
