It had been a quiet night. The soldier on sentry duty had heard no sound; all was calm. This was a relief, because after a full day in sole command, and a playdate to round things off in the late afternoon, she was absolutely knackered. She had gone through her checklist at the end of the day, making sure kit and rations were present and correct for roll-call next morning at 0700 hours, and then retired to keep watch over her charges, later than planned as usual.
At 0600 hours, the call for help came through on the radio, an hour earlier than expected.
"I need a poo! I need a poo! I NEED A POO!"
