Frederic C. Curry, From the St. Lawrence to the Yser with the 1st Canadian brigade
“ From our trench on the hill top we could see the long line of trenches, hidden here and there by trees, stretching southwards to Armentières, the tall chimneys of which were clearly discernible.Anxiously we glanced from this view to our watches while the hands crept slowly around to the appointed moment. In the distance there suddenly appeared faint lines of whitish smoke among the trees; and we lit our smoke bombs and hurled them over the parapet. There was a moment's pause, and then they burst into clouds of yellow smoke, hiding the German trench from view. ”
