During this period in billets the reorganized seniority of the Territorial Force was published, all temporary rank being cancelled. We suddenly found ourselves with no Majors and only four Captains, while several of our Company Commanders fell to 2nd-Lieutenants. The system of promotion to acting ranks was, however, at once instituted, and we resumed most of our original ranks, though Major Charles Wilson lost his majority, only one Major being allowed instead of two. About this time Captain Bowring took over command of "A" Company. On June 12th "A" Company relieved "C" Company in the subsidiary line, and on the 15th the battalion relieved the 2/7th K.L.R. The route chosen was Buterne Avenue, the common communication trench between ourselves and the right battalion. Owing to the destructive shooting of the enemy, Irish Avenue had more or less ceased to exist; and "C" Company, who once more found themselves in this unhealthy sector, had to use Cambridge Avenue and Regent Street, which made their relief a slow and tedious process. "B" Company was on the right, and then came "A" and "D" Companies. Owing to the raiding detachment being left out of the line, "D" Company had to be assisted by a loan of men from "C" Company; while "A" and "B" Companies were supplemented by various employed men--buglers, grooms, etc.--normally left out of the line. The sector was again full of gas, and the persistent efforts of the R.Es. to discharge it seriously hampered the patrolling that had to be carried out nightly in the vicinity of the area to be raided, and which was of vital importance. The real nature of the bridge over the ditches, which eventually proved to be a brick culvert, had long been in dispute, and Lieutenant Royle, the Intelligence Officer, spent every night while we were in Armentières with the Battalion scouts in No Man's Land up to and including the night of the raid. In spite of his multifarious duties as Intelligence Officer and his two daily summaries, he never spared himself in his efforts to make certain that the gaps were open and the routes beyond dispute. The enemy activity had meanwhile still further increased. Irish Avenue was reduced to a mere chain of shell-holes and débris, while every communication trench, and in fact every part of the sector, was well hammered. We were surprised and pleased to find how well the gas cylinders stood being knocked about.
