I ran back to her mother, pointed out where the child was, but she still seemed afraid to venture across.  Although my little adventure did not occupy over three minutes, I could wait no longer, and jumped on my horse and the train of wagons trotted sharply out of the square.  As the last wagon was leaving, I heard a sound like a train leaving a depot—­choo! choo! choo! choo! growing louder each instant, and as the tail-end of the last wagon was trotting out of the square a shell, the largest ever employed by the German command and called the Ypres Express, landed full in the square, killing every living thing there and destroying ambulances and wagons of every kind, catching our rear wagon and blowing it up, wounding the driver and destroying the magnificent Cloth Hall, the last vestige of this most beautiful piece of architecture being destroyed by the resulting fire.  That shell was from one of two guns that were expressly manufactured for the purpose of destroying the city of Ypres, a couple of months being taken to build cement platforms in which to set the ordnance, and the death-dealing monsters started on their mission of destruction from Dixmude, about 22 miles distant.

Not long after, an airplane located these monsters and succeeded in destroying one by a downpour of explosives he dropped on it, and the other one, a couple of days following, when being fired by its crew, the shell exploded in the gun itself, tearing it from its cement foundation and destroying itself and crew.  These were the only guns of that caliber that have ever been used, so far as is known.  The passage through the air of those missiles of death, heralded by their choo! choo! sent a shiver of dread up and down the lines as far as the sound would reach, and deep and lasting was the satisfaction of all ranks when the last of these mammoths of destruction wended its final flight.

CHAPTER V.

HUN HELPERS

On the sixth day after the first gas attack on the Canadians at Ypres, we took up a new position in a hedge about three-quarters of a mile north and a quarter of a mile east of Ypres, and about a thousand yards from the German trenches.  We galloped like mad over the shell-swept road, taking just exactly an hour and a half to get the guns placed and blazing.  We had four guns when we pulled into this position, but were latterly reinforced by two more from another battery, their sisters having been smashed and the crews bayoneted, including their commanding officers, and like friendless children they came to us looking for a home and were gladly taken in, thus increasing our battery to six guns.

The hedge of the thickly growing thorn bushes ranged to the height of four feet, making it incumbent upon us to continually assume a stooping position when walking, involving a crick in the back for a good part of the time while there, but the bush was as thick as could be and formed an admirable shelter.
