The general purpose and scope of the rehearsal of my three years' personal experience while in the artillery arm of the First Division of Canada's overseas forces is to lay before the reader an outline of the movement of our Division as it may be gathered from the performance of my own specific duties, with especial reference to the battles of Ypres (the 2nd), Givenchy, Sanctuary Woods (Ypres 3rd), the Somme and Vimy Ridge.
