From The Story of the 2/4th Oxfordshire and Buckinghamshire Light Infantry, by Captain G. K. Rose M.C. (Oxford: B.H. Blackwell, 1920)
On November 21 the Brigade took over its new sector of the line and with it a somewhat different régime to what it had known before. It was heard said of the 61st Division that it stayed too long in quiet trenches (to be sure, trenches were only really ‘quiet’ to those who could afford to visit them at quiet periods). Still the Somme ‘craterfield’ presented a complete contrast to the old breastworks with their familiar landmarks and daylight reliefs. Battle conditions remained though the advance had stopped. Our recent capture of Beaumont-Hamel and St. Pierre Divion left local situations, which required clearing up. The fragments of newly-won trenches above Grandcourt, trenches without wire and facing a No-Man’s-Land of indeterminate extent, gave their occupants their first genuine tactical problems and altogether more responsibility than before. In some respects the Germans were quicker than ourselves to adapt themselves to conditions approximating to open warfare. The principle of an outpost line and the system of holding our front in depth had been pronounced often as maxims on paper, but had resulted rarely in practice. Subordinate staffs, on whom the blame for local reverses was apt to fall rather heavily, were perhaps reluctant to jeopardise the actual front line by holding it too thinly, while from the nature of the case, the front line was something far more sacred to us than to the enemy. Since the commencement of trench warfare the Germans had held their line on the ‘depth’ principle, keeping only a minimum of troops, tritely referred to as ‘caretakers,’ in their front trench of all, while we for long afterwards crammed entire companies, with their headquarters, into the most forward positions.
