The 'All Clear' went at once after that. Its suddenness was something surprising, the mournful cheerful, long notes dying regretfully on a night that had only just gone quiet after the perfectly astonishing row. The moon had taken it into its head to rise; begumboiled, jocular and grotesque, it came from behind the shoulder of one of the hut-covered hills and sent down the lines of Tietjens' huts long, sentimental rays that converted the place into a slumbering, pastoral settlement. There was no sound that did not contribute to the silence, little dim lights shone through the celluloid casements. Of Sergeant- Major Cowley, his numerals gilded by the moon in the lines of A Company, Tietjens, who was easing his lungs of coke vapours for a minute, asked in a voice that hushed itself in tribute to the moonlight and the now keen frost.
