At our first halt a Battalion of the London Regiment was drawn up on parade in a field, and for the first time we opened the large red box and handed round the hymn-sheets. It was here that we were to begin to understand the wonderful uplifting power of our great English hymns when they are sung on great occasions. After all, the heart of a nation is often to be found in its hymns. They express a simple theology in simple terms, and words and tunes of hymns learned in childhood are very dear to men, even if in the rush of life they have not, as many said, "found much time for religion before I came to France." The Bishop had chosen hymns which he knew would be familiar to all the men of all denominations. Only four hymns were sung throughout the week--"When I Survey the Wondrous Cross," "Rock of Ages, Cleft for Me," "There Is a Green Hill Far Away," and "Jesus, Lover of My Soul"--hymns which are known throughout the world wherever British men have gone. There was no necessity to have an accompaniment, for everybody knew the tunes. Once or twice a band was present, and now and then a small harmonium was used, but as a rule the hymns were sung unaccompanied, except by the thunder of the guns. It is always moving and inspiring to join in hymns when they are sung by large bodies of men, especially when those hymns have been associated with great moments in our lives, but never before can these familiar tunes have had such a setting; never, certainly, have they been sung more reverently or with greater earnestness. Perhaps, as children they liked the tunes best, but now that they have become men and put away childish things, the soldiers think first of the words. How much those words meant to many hearts no one but He to Whom all hearts are open can ever know; but that they moved thoughts too deep for words was clearly written on every face in those great gatherings of men. As they must have raised many memories of childhood in the hearts of many of the men, so now they will in future years be sung by many with another and a deeper memory of the occasions when they were sung upon the battlefields of Flanders in the days of the Great War. There was one verse in the Gospels which was continually in my mind at these great services. In Holy Week, of course, we were often thinking of that last night of our Lord with His disciples in the upper room at Jerusalem before He went out to His great battle in Gethsemane, and on the Cross: "When they had sung an hymn, they went out into the Mount of Olives." We were with men at the great moments of their lives, many of them having come straight out of the trenches, many going back to the trenches in but a few moments after we had left them--men who had been in battle, and men who were preparing for battle. Nobody who was present at those services would ever forget what it meant to say: "And when they had sung a hymn, they went back to the trenches."
