One of my best friends in Vienna was Ernst Karczag. Shortly after the outbreak of the war I received a postal from him stating that he was about to rejoin his regiment--he was a lieutenant in a crack hussar regiment--and proceed to the Galician front. At Christmas I received a long letter from him and a photograph of himself in his hussar uniform. Then one morning in March I received a cablegram from a mutual friend in London, stating that Ernst had died of cholera in Poland. Ernst was in his twenty-fifth year and was tenderly attached to his mother. Until the war broke out he had never been away from home except on a brief holiday, and his long absence at the front last winter brought his mother to the verge of a nervous collapse. It came to a point where it was absolutely necessary for her to see her son. Mr. Karczag, although a millionaire and a man of considerable influence, was unable to get a pass for his wife to visit the line near Lodz in Poland, where the son's regiment was stationed. She set out for Lodz alone. After nearly a week of the hardest kind of travelling, much of it in troop trains, she reached Lodz, where she found every hotel occupied by German and Austrian officers. In desperation she decided to appeal to Gen. Mackensen, the famous German General, who was in supreme command. "You shall see your son to-morrow morning," he told her when he learned that her boy was a lieutenant of a certain hussar regiment. "I am reviewing the Austrian troops at 6 o'clock to-morrow morning. If you will come to my headquarters at that time I shall permit you to witness the review." The review of the Austrian troops lasted nearly five hours, and it was witnessed by Gen. Mackensen, his staff and the mother of my friend. Regiment after regiment passed by, but there was no sign of the young hussar officer. The anxious mother was almost ready to break down, when at the very end of the last regiment in the review she caught sight of her son. Forgetting her peculiar position she called to her boy. But he did not hear her, and a few moments later he galloped out of sight. "I must have a few words with my boy," she pleaded with Gen. Mackensen; "I must talk with him." Evidently she struck a sympathetic chord in his nature, for he told her he would send a motor car to the hotel to take her to her son's regiment. For two days she waited for the car, but as it did not arrive she again went to Gen. Mackensen's headquarters, only to learn that he had been called away to another position on the front. Apparently he had forgotten all about his promise. There was no one to help her, so she started out alone to reach the little Polish village where her son's regiment was stationed. No conveyance was obtainable for any sum, so for three days and three nights the poor mother walked the frozen roads to her son's side.
