Although I had resigned my commission as an officer two years before, I immediately left Switzerland, accompanied by my wife, in order to report for duty. As it happened, a wire reached me a day later calling me to the colors.

We started at once to dig our trenches, half of my platoon stepping forward abreast, the men being placed an arm's length apart. After laying their rifles down, barrels pointing to the enemy, a line was drawn behind the row of rifles and parallel to it.

My wife volunteered her services as Red Cross nurse, insisting upon being sent to the front, in order to be as near me as could be, but it developed later that no nurse was allowed to go farther than the large troop hospitals far in the rear of the actual operations.

One gets into a strange psychological, almost hypnotic, state of mind while on the firing line which probably prevents the mind's eye from observing and noticing things in a normal way.
