15 December 1917; Saturday

Took over at midnight. Did some French and wrote a short letter to Charlie. Didn’t sleep well all day. Warned for a new arrangement and to start at 8 tomorrow night instead of 4 o’clock to-night. Lay in bed. A few minutes later warned for duty at once and had to get up. No sooner on duty than warned to clear up and go back to bed and return to headquarters first thing in the morning. Returned to bed.
