Early that afternoon we got a message that another Column was coming to relieve us, and that we were to return to Zyradow for a rest. We were very sorry to leave our little dressing-station, but rejoiced to hear that we were to go up again in two days' time to relieve this second Column, and that we were to work alternately with them, forty-eight hours on, and then forty-eight hours off duty. We had left Zyradow rather quiet, but when we came back we found the cannon going hard, both from the Radzivilow and the Goosof direction. It would have taken much more than cannon to keep _us_ awake, however, and we lay down most gratefully on our stretchers in the empty room at the Red Cross Bureau and slept. A forty-eight hours' spell is rather long for the staff, though probably there would have been great difficulty in changing the Columns more often. I woke up in the evening to hear the church bells ringing, and remembered that it was Christmas Eve and that they were ringing for the Midnight Mass, so I got up quickly. The large church was packed with people, every one of the little side chapels was full and people were even sitting on the altar steps. There must have been three or four thousand people there, most of them of course the people of the place, but also soldiers, Red Cross workers and many refugees mostly from Lowice. Poor people, it was a sad Christmas for them--having lost so much already and not knowing from day to day if they would lose all, as at that time it was a question whether or not the Russian authorities would decide for strategic reasons to fall back once more. And then twelve o'clock struck and the Mass began. Soon a young priest got up into the pulpit and gave them a little sermon. It was in Polish, but though I could not understand the words, I could tell from the people's faces what it was about. When he spoke of the horrors of war, the losses and the deaths and the suffering that had come to so many of them, one woman put her apron to her face and sobbed aloud in the tense silence. And in a moment the whole congregation began sobbing and moaning and swaying themselves to and fro. The young priest stopped and left them alone a moment or two, and then began to speak in a low persuasive voice. I do not know what he said, but he gradually soothed them and made them happy. And then the organ began pealing out triumphantly, and while the guns crashed and thundered outside, the choir within sang of peace and goodwill to all men.
