But at such moments there's nothing so steadying to mind and senses as something definite to do. Earlier on I had noted marked on a Corps signalling-map a test-box between the quarry and the canal and another one along the railway embankment, not far from the retiring positions assigned to the batteries. If we could find them the labour of laying an overland telephone wire from the quarry to the opposite side of the canal would be saved. We set out, got off the roadway, and did a good deal of floundering about in hedge-bottoms and over waste lands; but the important thing was that we found both test-boxes, and that the buried cables we hoped for were there. 10.30 P.M.: I had reeled out my lines alongside the railway from the test-box to D Battery and to C and A, who, because of the nine guns the brigade had lost in the morning, had become a composite battery. They had crossed the canal in comparative quiet and were now laying out lines of fire by compass bearings. B Battery were coming along to a spot near the railway farther north, and my signallers were waiting to connect them up. Things were indeed getting ship-shape again. I had spoken through to the colonel and put him in touch with his battery commanders, and to the F.O.O. left at the rearmost O.P. on the eastern side of the canal. The colonel had issued a night-firing programme just as if we were in settled positions, and with fresh ammunition arriving from the original waggon lines the batteries began "pooping off" with brisk enthusiasm, their object being, of course, to cover the retirement of our infantry. Every one of us had turned out that morning immediately the Hun bombardment started. No sleep could be looked for that night either; but there was the morrow, March 22nd, to be reckoned with--it might entail even more wear and tear than the day which was ending; so I sent back to the waggon lines all but six of the signallers, the brigade clerks, the two wireless operators, who had nothing whatever to do, and most of the servants, telling them to get as much sleep as possible. The colonel's servant was still in the quarry guarding our castaway kit; my own servant I had stationed on the canal bridge so that he could report to me as soon as the sergeant-major and the rescuing waggon hove in sight. Our discovery of the buried cable running under the canal had a sequel equally welcome. One of the telephone linemen said he believed there was another "bury" on the far side of the railway cutting, and that it connected with the back areas. The signalling-sergeant and myself set out on another hunt, and, joy! we discovered, after patient test calls with a D.III. telephone, that by speaking through two exchanges we could communicate with our own Divisional H.Q. It was six hundred yards from the railway cutting, but I could now keep in touch with the colonel in front, the batteries to right and left of me along the railway, and the brigadier-general and the brigade-major in rear.
