On the 25th July the Division was relieved after a continuous tour in the Loos front of just under five months--a period of particularly bitter and severe trench warfare. Trench-mortaring was continuous on both sides on the greater part of the front held, and shelling heavy. The artillery suffered no less severely than the infantry, owing to the very restricted choice of positions and the advantages of the observation enjoyed by the enemy. Raids and counter-raids were numerous. An analysis of the diary shows that during the six months from the end of January to the end of July the Division carried out 30 raids, of which 13 were successful in obtaining their objective and securing prisoners (total for the 13 raids: 54), 11 secured their objective but failed to yield any prisoners, and only 6 definitely failed. During the same period the enemy attempted 21 raids, of which only 4 succeeded in taking prisoners, 5 entered our trenches without securing any prisoners, and 12 were entire failures. Three of the enemy's attempted raids yielded us prisoners, and 4 yielded identifications. The low average of prisoners taken by us in successful raids is attributable to two causes--first the extraordinary precautions taken by the enemy in the latter part of the period to avoid losing prisoners by evacuating his trenches on the slightest alarm or remaining in his dug-outs, and secondly the fierceness engendered in our troops by the severity of the bombardment, and particularly of the trench-mortaring to which they were normally subjected. A very successful battalion raid by the 1st The Buffs on the 24th June, which yielded 15 prisoners, might have made a better showing if it had not followed closely on the receipt of the mail containing accounts of an enemy bombing raid on Folkestone.
