One of the special delights of the Commanding Officer was crawling about exposed parts of the sector by day. It was not only his anxiety to acquire an accurate knowledge of his sector, though that was certainly one reason; he wanted to find out where every derelict trench led to, what secrets lay hidden in those areas of abandoned chaos in which the sector abounded, and no one could ever have known his sector better than did Colonel Fletcher. But apart from all this, his old big-game hunting instincts were aroused. This time he was not tracking the shy koodoo or the skulking lion, but matching his brains and his woodcraft against the ever-watchful German. Major Geddes more than once accompanied him on these excursions, as he crawled and wriggled on his stomach from place to place, now lying up to use telescope and field-glasses, now tracing out all the intricacies of our own or the enemy trenches. Home the pair would come at last, with the perspiration streaming down their faces. "Well, that is the best afternoon I have had since the war started!" the Commanding Officer would exclaim, as he sat mopping his face and drinking large cups of tea. The gas attack had originally been fixed for the night of May 20th-21st. The targets selected for the projectors were Census Support Line, Les 4 Hallots Farm, and Battalion Headquarters at Census Farm. The inclusion of the latter target caused some people certain misgivings, as they had a suspicion--afterwards confirmed from a captured German map--that our own Headquarters were not unknown to the enemy. The usual invasion of our sector by "N" and "L" Special Companies, R.E., took place on the night in question. Extra telephones had been rigged up, and in addition cryptic messages about "presentations of medals" and "indents for bicycles" came frequently over the 'phone. At the last moment the wind veered round, as it frequently did at night. It was too late to cancel the orders by message, so a special signal rocket was fired from Headquarters. It was a red, green and red rocket. The first one lighted refused to move at all; but the second, a parachute light, went up with a roar for about twenty feet, and then sailed off along the subsidiary line. Fortunately, it was successful in stopping the discharge of the gas. We took a more than usual interest in this discharge, as it appeared that we could not be relieved till it took place. However, in the end, when we had been in ten days, the attack was definitely postponed for twenty-four hours to allow the relief to be effected. On the early morning of May 22nd 2nd-Lieutenants Hodgkinson and Little with patrols attempted entries into the German line at Cell Trench, opposite Hobbs Farm and at Centaur Trench respectively. Both were spotted and heavily bombed, Little being slightly wounded, but not sufficiently for evacuation. Lieutenant Alcock two days previously had been hit in the eye by a splinter from a "pineapple," and had retired temporarily to a
