In the previous volume of this work, which dealt with the doings of the British Army in France and Flanders during the year 1914, I ventured to claim that a great deal of it was not only accurate but that it was very precisely correct in its detail. This claim has been made good, for although many military critics and many distinguished soldiers have read it there has been no instance up to date of any serious correction. Emboldened by this I am now putting forward an account of the doings of 1915, which will be equally detailed and, as I hope, equally accurate. In the late autumn a third volume will carry the story up to the end of 1916, covering the series of battles upon the Somme.The three years of war may be roughly divided into the year of defence, the year of equilibrium, and the year of attack. This volume concerns itself with the second, which in its very nature must be less dramatic than the first or third. None the less it contains some of the most moving scenes of the great world tragedy, and especially the second Battle of Ypres and the great Battle of Loos, two desperate conflicts the details of which have not, so far as I know, been given up to now to the public.Now, as before, I must plead guilty to many faults of omission, which often involve some injustice, since an author is naturally tempted to enlarge upon what he knows at the expense of that about which he is less well informed. These faults may be remedied with time, but in the meantime I can only claim indulgence for the obvious difficulty of my task. With the fullest possible information at his disposal, I do not envy the task of the chronicler who has to strike a just balance amid the claims of some fifty divisions.
