It only remains to be added that on the extreme left of the line the Germans attempted a counter-attack while the main battle was going on. It was gallantly urged by a few hundred men, but it was destined to complete failure before the rifles of the 89th Brigade of the Thirtieth Division (Williams). Few of these Germans ever returned. It was a one day's battle, a single hammer-blow upon the German line, with no ulterior operations save such as held the ground gained, but the battle has been acclaimed by all critics as a model and masterpiece of modern tactics, which show the {110} highest power of planning and of execution upon the part of Sir Herbert Plumer and his able Chief-of-Staff. The main trophy of course was the invaluable Ridge, but in the gaining it some 7200 prisoners fell into British hands, including 145 officers, which gives about the same proportion to the length of front attacked as the Battle of Arras. The Germans had learned wisdom, however, as to the disposition of their guns in the face of "the unwarlike Islanders," so that few were found within reach. Sixty-seven pieces, however, some of them of large calibre, remained in possession of the victors, as well as 294 machine-guns and 94 trench mortars. The British losses were about 16,000. The military lesson of the battle has been thus summed up in the words of an officer who took a distinguished part in it: "The sight of the battle-field with its utter and universal desolation stretching interminably on all sides, its trenches battered out of recognition, its wilderness of shell-holes, _débris_, tangled wire, broken rifles, and abandoned equipment, confirms the opinion that no troops, whatever their morale or training, can stand the fire of such overwhelming and concentrated masses of artillery. With a definite and limited objective and with sufficient artillery, complete success may be reasonably guaranteed." It is the big gun then, and not, as the Germans claimed, the machine-gun which is the Mistress of the Battle-field. The axiom laid down above is well proved, but it works for either side, as will be shown presently where upon a limited area the weight of metal was with the Germans and the defence with the British. ------------------------------------------------------------------- {111} [Illustration: Order of Battle, MESSINES, June 7, 1917] -------------------------------------------------------------------
