An article by General Wauchope appeared in _Blackwood's_, 'The Battle that won Samarrah.' This article not only stressed the fact that the Black Watch were first in Baghdad and Samarra--an accident; they were the freshest unit on each occasion, while other units were exhausted from fighting just finished--but dismissed the second day of 'the battle that won Samarra' with one long paragraph, from which the reader could get no other meaning except the one that this day also was won by the same units as did the fighting of the 21st. This was a handling of fact which appealed neither to the Black Watch, whose achievements need no aid of embellishment from imagination, nor to the Leicestershires, who were made to appear spectators through the savage fighting of two days. If the reader turns to the chapter in this book entitled 'The Battle for Samarra,' he will learn what actually happened on April 22, 1917. The only other reference in print, that I know of, to the fighting for Samarra is the chapter in Mr. Candler's book. This, he tells us, was largely taken over by him from a journalist who visited our battlefields during the lull of summer. He showed the account to officers of my division, myself among them, and they added a few notes. But the chapter remained bare and comparatively uninteresting beside the accounts of actions which Mr. Candler had witnessed. For this book, then, my materials have been: First, my own experience of events _quorum ego pars minima_. Next, my own note-books, carefully kept over a long period in Mesopotamia and Palestine, a period from which these two campaigns of Samarra and Tekrit have been selected. Thirdly, I saw regimental war-diaries and talked with brigade and regimental officers. Most of all, from the Leicestershires I gained information. It is rarely any use to question men about an action; even if they speak freely, they say little which is of value on the printed page. One may live with a regimental mess for months, running into years, as I did with the Leicestershires' subalterns, and hear little that is illuminating, till some electric spark may start a fire of living reminiscence. But from many of my comrades, at one time and another, I have picked up a fact. I am especially indebted to Captain J.O.C. Hasted, D.S.O., for permission to use his lecture on the Samarra battle. I could have used this lecture still more with great gain; but I did not wish to impair its interest in itself, as it should be published. From Captain F.J. Diggins, M.C., I gained a first-hand account of the capture of the Turkish guns. And Major Kenneth Mason, M.C., helped me with information in the Tekrit fighting. My brother, Lieutenant A.R. Thompson, drew the maps.
