The Great War is one that for the most part is painted in broad strokes, with the fine points having become blurred over time. Recreating the details- the experiences of the men who fought it- is a painstaking process. Millions died, so there are millions of pieces to the puzzle. It is through efforts like this that a more full accounting of the War is preserved, the fine details brought to light.
The causes of the War notwithstanding, it is the collective experience of the men that fought it that is most in need of preserving. To that end, Geoff Crompton has definitely "done his bit".
