And the little graveyard in rear of the line was to receive the bodies of many of our comrades and hold them in common sanctity with those of other gallant men, British and French, Highlanders and Turcos, who had perished on the slopes of Messines.

For a week we systematically registered our guns on new points in the enemy's second and third lines—the usual preliminary to an offensive—and bombarded them severely.

This was done to prevent the enemy from moving any of his guns from this area to the southern end of the line, where, now that the weather was again favourable, the British were to make another thrust.

For this purpose, too, we were to make a "little demonstration" on our front, using smoke bombs to make the enemy believe we were going to use gas, and, to our great satisfaction, it was announced that in those areas where the real offensive was being made the Germans would be treated to a dose of their own poison. Too long we had waited and allowed the enemy to use this fearful weapon against us, thinking the neutral nations might intervene; but their interest in the cause of humanity was largely a financial one, and we determined to adopt a broader view, perhaps, of what justifiable weapons are, and make use of the advances of science. France was already using the gas, but Britain hesitated at setting her hall-mark on such a usage, necessary as it had become.

The day, October 13th, was ideal for observation, beautifully clear, with a gentle breeze from our trench towards the enemy's. Nothing finer could be desired for our operations to the south.

About 2 o'clock our guns, along the whole British front, started to cut wire as though preparing for an attack.

The Germans in return sprinkled our lines vigorously with shrapnel, the fleecy white puffs of their shells showing up like clouds on the clear blue sky.

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.
