These five plays were written, in the order in which they appear now, during the years 1916 and 1917. They would hardly have been written had it not been for the war, although only one of them is concerned with that subject. To his other responsibilities the Kaiser now adds this volume. For these plays were not the work of a professional writer, but the recreation of a (temporary) professional soldier. Play-writing is a luxury to a journalist, as insidious as golf and much more expensive in time and money. When an article is written, the financial reward (and we may as well live as not) is a matter of certainty. A novelist, too, even if he is not in "the front rank"-but I never heard of one who wasn't-can at least be sure of publication. But when a play is written, there is no certainty of anything save disillusionment. To write a play, then, while I was a journalist seemed to me a depraved proceeding, almost as bad as going to Lord's in the morning. I thought I could write one (we all think we can), but I could not afford so unpromising a gamble. But once in the Army the case was altered. No duty now urged me to write. My job was soldiering, and my spare time was my own affair. Other subalterns played bridge and golf; that was one way of amusing oneself. Another way was-why not?-to write plays.
