We reached a narrow road, crowded with battery ammunition waggons going up to the new positions. Darkness had descended, and when you got off the road to avoid returning vehicles it was necessary to walk warily to escape tumbling into shell-holes. "The blighters have got a new way of worrying us now," went on the adjutant. "They've planted land-mines all over the place, particularly near tracks. Lead-horses are always liable to put a foot against the wire that connects with the mine, and when the thing goes off some one is nearly always hurt. D Battery had a nasty experience this afternoon. Kelly tried to take a section forward, and the Boche spotted them and shelled them to blazes. As they came back to get away from observation one of the teams disturbed a land-mine. The limber was blown up, and one driver and two horses were killed.... Look here, if we move off in this direction we ought to save time; the railway must be over there and the place for our Headquarters is not far from it, in a trench where the O.P. used to be." We found ourselves on some shell-torn ground that was cut up also by short spans of trenches. One part of it looked exactly like another, and after ten minutes or so we decided that we were wandering to no purpose. "There are some old German gun-pits close by," panted the adjutant in further explanation of the place we were seeking. All at once I saw a thin shaft of light, and blundered my way towards it. It proved to be a battery mess, made in a recess of a trench, with a stout tarpaulin drawn tight over the entrance. I hailed the occupants through the tarpaulin, and on their invitation scrambled a passage inside. A young captain and two subalterns listened to what I had to say, and gave me map co-ordinates of the spot on which we now were. When I mentioned German gun-pits the captain responded with more helpful suggestions. "It's difficult finding your way across country, because the trenches wind about so, but follow this trench as it curves to the right, and when you come to an old British dug-out blown right in, go due north across country; then you'll come to the railway," he said. We thanked him, plodded on, reached a point on the railway quite half a mile beyond the spot we wanted, and then out of the darkness heard the voice of Henry of C Battery. We drew near, and found him in the mood of a man ready to fight the whole world. "Dam fools," he grumbled: "there's a sergeant of A Battery who's taken a wrong turning and gone into the blue, and half a dozen of my waggons have followed him.... And B Battery have a waggon tipped over on the railway line, just where we all cross, and that's holding everything else up."
